Developed Countries

Highlights Duration: The coronavirus is still weighing on yields and could push them down further in the near-term. However, the history of past viral outbreaks suggests that yields will move sharply higher once the daily number of new cases falls to zero. Fed: We would speculate that, this year, the Fed is very likely to change its framework so that it can seek a temporary overshoot of its 2% inflation target. This may involve moving to an “average inflation targeting” regime implemented via operational inflation ranges. Labor Market: It is very likely that employment growth peaked for the cycle in 2015, but falling employment growth is only consistent with the end of the economic recovery when it breaks below monthly labor force growth, causing the unemployment rate to rise. Feature Chart 1Fresh Lows! The ultimate economic fallout from the coronavirus remains uncertain, but bond investors are starting to fear the worst. As we go to press, the 10-year and 30-year Treasury yields have both made new cyclical troughs at 1.36% and 1.83%, respectively (Chart 1). The 3-month / 10-year Treasury slope is once again inverted and the 2/10 slope is down to 11 bps, from 34 bps at the start of the year (Chart 1, bottom panel). This behavior tells us that the market is pricing-in a significant economic slowdown stemming from the coronavirus, one that will force the Fed to ease policy this year. Indeed, the overnight index swap curve is priced for more than 50 bps of rate cuts during the next 12 months, and fed funds futures are discounting 58% chance of a 25 basis point rate cut in either March or April. In direct opposition to the market’s moves, the past week saw several FOMC members push back against the idea of a rate cut. Atlanta Fed President Raphael Bostic said in an interview:1 There are many different scenarios about what’s going to happen between now and say June or July. My baseline expectations are that the economy is not going to see rising risks and it’s going to stay stable, so we won’t have to do anything. St. Louis Fed President James Bullard was even more forceful, saying:2 There’s a high probability that the coronavirus will blow over as other viruses have, be a temporary shock and everything will come back. But there’s a low probability that this could get much worse. Markets have to price that in, and that drags down the center of gravity a little bit. But if this all goes away, I expect that pricing will come back out of the market and we’ll be back to the on-hold scenario. Finally, Fed Vice Chair Richard Clarida challenged the notion that expectations for a 2020 rate cut are widespread. Similar to Bullard, he claimed that market prices reflect hedging against potential downside risks. He went on to cite survey measures that show investors looking for a flat funds rate in their base case scenarios.3 There’s a wide gap between survey and market rate expectations. Clarida’s point about the discrepancy between market and survey rate expectations is well taken. Chart 2 shows that the median forecast from the New York Fed’s Survey of Market Participants calls for an unchanged fed funds rate through 2022. However, it’s important to note that this survey was taken prior to the January FOMC meeting, when the coronavirus was only just starting to hit the news. Chart 2A Wide Gap Between Market And Survey Expectations Do They Protest Too Much? We can sympathize with the FOMC’s desire to push back against market expectations that it feels are off target, but we also think the strategy could prove self-defeating. If the market starts to believe that the Fed will not ease policy quickly enough, the yield curve will flatten even more and risk assets (equities and credit spreads) will sell off. Both of those developments would increase the pressure on the Fed to ease policy. Chart 3The History Of Viral Outbreaks In fact, if the present market turmoil continues, the Fed is very likely to deliver a rate cut sometime this year in an effort to support confidence and limit the potential economic damage from the coronavirus. Unfortunately, at this point we have no idea whether the coronavirus will spread further during the next couple of months, or whether it will be contained. In the former scenario, financial conditions will continue to tighten and the Fed will ease policy. In the latter scenario, financial conditions will not tighten aggressively and the Fed will stay on hold. In either case, given the uncertainty of the situation, we recommend stepping aside on our prior recommendation to short the August 2020 fed funds futures contract. No matter how long it takes to contain the coronavirus, we would expect growth to rebound quickly once the situation is resolved. This has been the pattern of past viral outbreaks: a steady decline in bond yields that sharply reverses course when the daily number of new cases reaches zero (Chart 3). Even accounting for its sharp drop during the past few days, the 10-year Treasury yield is still tracking the pattern of past viral outbreaks, and a jump in yields seems likely once the virus is contained. For this reason, we are inclined to maintain below-benchmark duration on a 12-month horizon. The US Election Is The Biggest Risk To Our Cyclical View The main risk to our 6-12 month below-benchmark portfolio duration stance is the possibility that as soon as the market is done worrying about the coronavirus it jumps right to worrying about the outcome of the US election. This could keep Treasury yields low throughout all of 2020. We argued last week that Treasury yields could come under downward pressure if Bernie Sanders looks set to win the election, while a victory for Donald Trump or one of the other Democratic candidates would be neutral for yields.4 As it stands now, Sanders has taken a more decisive lead in the Democratic leadership race after winning in Nevada. But President Trump’s approval rating has also been tacking higher. We will continue to monitor this risk closely in the coming weeks, and may alter our cyclical duration view depending on how polls evolve in March. The Fed may be forced to cut rates this year if financial conditions continue to tighten. Bottom Line: The coronavirus is still weighing on yields and could push them down further in the near-term. However, the history of past viral outbreaks suggests that yields will move sharply higher once the daily number of new cases falls to zero. Likewise, credit spreads have near-term upside until the virus is contained, but will tighten anew once the threat has passed. As discussed last week, the fundamental credit cycle backdrop remains supportive.5 The Fed may be forced to cut rates this year if financial conditions continue to tighten. Dual Mandate Update As discussed above, Fed participants generally view the current level of interest rates as appropriate and have been reluctant to hint at any upcoming policy changes. It’s not that difficult to see why. If we recall that the Fed’s dual mandate – as set by Congress – is to pursue maximum employment and price stability, then it’s pretty clear that current policy is delivering on both fronts. Chart 4 shows that the sum of the unemployment rate and 12-month consumer price inflation – the so-called Misery Index – is about as low as it has been since the 1960s. Further, the outlook for 2020 is that employment growth will remain firm and inflation tepid. Chart 4The Fed Has The Economy In A Good Spot Labor Market Chart 5Employment Growth Greater Than Labor Force Growth It is very likely that employment growth peaked for the cycle back in 2015, but falling employment growth is only consistent with the end of the economic recovery when it breaks below monthly labor force growth, causing the unemployment rate to rise. During the past 12 months, monthly employment gains have averaged +171k compared to a +122k average increase in the labor force (Chart 5). In other words, employment growth is slowly trending down but it remains at a comfortable level. Beyond decelerating employment, rising labor force participation is the other important trend in the US labor market. While it’s tempting to think that stronger labor force growth might only raise the bar for what employment growth is necessary to keep the recovery on track, this is not the case. In practice, gross labor flow data show that, since 2017, 73% of people that entered the labor force transitioned directly to being employed. Only 27% of those entering the labor force transitioned to unemployed status. Simply, rising labor force growth tends to push employment growth higher as well. It does not make it more likely that the unemployment rate will rise. Rising labor force participation has not gone unnoticed. The minutes from January’s FOMC meeting revealed that: Many participants pointed to the strong performance of labor force participation despite the downward pressures associated with an aging population, and several raised the possibility that there was some room for labor force participation to rise further. The prime age participation rate is already back to pre-crisis levels and the female 24-54 part rate is making new highs (Chart 6). Nonetheless, US prime age participation remains low compared to other developed countries – like its closest neighbor Canada – making further gains possible. Chart 6Do Part Rates Have More ##br##Upside? Chart 7Don't Be Alarmed By The Drop In Job Openings Finally, many have pointed to the recent drop in Job Openings as a reason to be concerned about the state of the US labor market (Chart 7). We view these concerns as unfounded. First, the drop in openings does not appear to be related to flagging labor demand. The Job Hires rate is steady and involuntary layoffs are low. Against a backdrop of steady demand, fewer openings could simply mean that there is a little more slack in the labor market than was previously thought. Inflation On inflation, we see little chance of a meaningful surge this year. The Prices Paid and Supplier Delivery components of the ISM Manufacturing index, two indicators that tend to lead changes in core inflation, are downtrodden (Chart 8). Meanwhile, base effects could cause 12-month core CPI to jump in the next month or two, but are more likely to drag it down on a 6-month horizon (Chart 8, bottom panel). Chart 8Inflation Will Remain Tame In 2020 At the component level, shelter is the largest component of core CPI but it is unlikely to accelerate in the coming months. The National Multifamily Housing Council’s Survey of Apartment Market Conditions just ticked below 50 (Chart 9). Shelter inflation is more likely to rise when the index is firmly above 50 in “tightening” territory. Further, the recent jump in core goods inflation is set to wane in the coming months. Core goods inflation tracks non-oil import prices with a lag of about 18 months, and import prices have been on a declining trend (Chart 9, bottom panel). Chart 9Shelter And Core Goods Inflation Bottom Line: The Fed is performing well on its dual mandate. Employment growth is firm, inflationary pressures are tepid and continued accommodative monetary policy might be able to pull more people into the labor force. Absent any desire to preemptively ease to counteract the effects of the coronavirus, the Fed’s on hold policy stance is appropriate. Tracking The Fed’s Balance Sheet We strongly disagree with the suggestion that the increase in the size of the Fed’s balance sheet meaningfully impacted Treasury yields or risky assets this year.6 But the Fed’s balance sheet policy remains a point of interest nonetheless, and last week we received more information about what the Fed intends to do with its balance sheet this year. Specifically, the Fed has decided that $1.5 trillion will serve as a firm floor for bank reserves. That is, the Fed will not allow the supply of reserves to fall below that level, and will typically maintain a significant buffer above $1.5 trillion. To accomplish this, the Fed would prefer to transition away from daily repo transactions. It would rather rely on its Treasury and T-bill purchases to keep reserves at desired levels. $1.5 trillion will be the firm floor on bank reserves.   With that in mind, the Fed now plans to scale daily repo operations back to zero by the end of April. The Fed’s $60 billion per month T-bill purchases will continue through the second quarter. After that, the pace of asset purchases will be lowered, with the goal of simply keeping reserve supply stable. It has not yet been decided whether Treasury purchases after June will be concentrated in T-bills or spread out across the maturity spectrum. Chart 10 and Table 1 show our updated projections for what the Fed’s balance sheet will look like at the end of June. Our projections show a reserve level of $1.7 trillion at the end of June, significantly above the $1.5 trillion floor. This provides a healthy buffer in case a spike in the Treasury’s General Account leads to a temporary drop in reserve supply. Chart 10The Fed's Balance Sheet Securities And Reserves Table 1Fed's Balance Sheet Projections The Biggest Changes The Fed Could Make This Year (And More Details About The Ongoing Strategic Review) Chart 11Monitoring Financial Conditions The minutes from the January FOMC meeting, released last week, revealed a few important details about the Fed’s ongoing strategic review. The strategic review is a process that the Fed expects to complete by mid-year, where it will consider potential changes to its monetary policy strategy, tools and communication practices. At the last FOMC meeting, the committee took up the issues of how to incorporate financial stability into the Fed’s monetary policy strategy and of whether it should consider targeting an inflation range instead of a specific point. Financial Stability The traditional consensus in central banking was that interest rates should not be used to manage financial stability risks. Rather, monetary policy should remain focused on the dual mandate of full employment and inflation. In January’s discussion, FOMC participants generally agreed that macroprudential and regulatory policies remain the preferred methods for dealing with financial stability risks. But participants also recognized that this might not suffice: Many participants remarked that the Committee should not rule out the possibility of adjusting the stance of monetary policy to mitigate financial stability risks, particularly when those risks have important implications for the economic outlook and when macroprudential tools had been or were likely to be ineffective at mitigating those risks. At January’s FOMC meeting, the Fed staff also presented the idea of a “financial stability escape clause” that would “provide leeway for the central bank to deviate from its usual monetary policy strategy if financial vulnerabilities become significant.” For our part, we have consistently argued that, if inflation expectations remain stubbornly low, the Fed may eventually lift rates this cycle in response to signs of excess in financial markets.7 So far, we don’t see asset valuations as stretched enough to prompt Fed tightening (Chart 11), but the longer that interest rates stay low, the more likely it is that financial market valuations will reach bubbly levels. Inflation Ranges The FOMC discussed two types of inflation ranges at the January FOMC meeting. They discussed ranges that are symmetrical around the Fed’s 2% target, and “operational ranges” that could be moved around depending on the Fed’s policy goals. In theory, the advantage of a symmetric inflation range around the Fed’s 2% target is that it could help communicate the inherent uncertainty in measuring inflation, and the difficulty in forecasting it with precision. However, participants worried that introducing a symmetric inflation range at a time when inflation has been running below the Fed’s 2% target would signal that the Fed is comfortable with below-target inflation. In contrast, the idea of an operational range has some appeal, especially if the Fed decides to shift from a pure forward-looking 2% inflation target to a target that seeks to achieve average 2% inflation over time. How would this work? In an environment where inflation had been running below 2% for several years, the Fed would set its operational range to be 2%-2.5% for a time (Chart 12). Once it judged that enough of an overshoot of 2% had taken place to make up for past downside misses, it would shift back to a symmetric operational range of say 1.75%-2.25%. Or perhaps, if it judged that inflation needed to undershoot 2% for a time, it would set its operational range as 1.5%-2%. Crucially, the operational range would be moved around at the discretion of the Committee with the goal of achieving 2% inflation on average over time. Chart 12The Fed Could Adopt An Operational Target Inflation Range of 2-2.5 This Year The Most That Could Be Announced This Year Based on the info we’ve received so far from the FOMC minutes and the speeches of several Fed Governors, two in particular from Governor Lael Brainard.8 We now have a decent sense of the most dramatic changes that could be announced this year. In all likelihood, the announced changes will be somewhat less dramatic than those listed below, as consensus amongst committee members on all the details will be difficult to achieve. The Fed will change from a forward-looking 2% inflation target to one that seeks to achieve average inflation of 2% over time. It will implement its new inflation targeting framework by using operational inflation ranges that will be moved around at the discretion of the Committee. The Fed will allow for the possibility of changing interest rates in response to financial stability risks, if it is thought that those risks threaten the dual mandate of full employment and 2% inflation. It will announce a new tool for implementing monetary policy at the zero-lower bound where it puts a hard cap on bond yields out to some specific maturity. The cap won’t be lifted until some specified economic goals are met. We would speculate that, this year, the Fed is very likely to change its framework so that it can seek a temporary overshoot of its 2% inflation target. This may involve moving to an “average inflation targeting” regime implemented via operational inflation ranges, or it could be a more watered down version of the same idea. Similarly, we would also expect that any announced changes to the Fed’s policy strategy will include more explicit language related to financial stability risks. As for the idea of adopting bond yield caps at the zero-lower bound, a policy that is similar to the Bank of Japan’s current Yield Curve Control policy. This may not be announced this year, especially since the Fed probably believes that it has more time to mull over this sort of proposal.   Ryan Swift US Bond Strategist rswift@bcaresearch.com Footnotes 1 Please see “CNBC Exclusive: CNBC Transcript: Atlanta Fed President Raphael Bostic Speaks with CNBC’s Steve Liesman on CNBC’s “Squawk Box” Today,” CNBC, dated February 21, 2020. 2 Please see “CNBC Exclusive: CNBC Excerpts: St. Louis Fed President James Bullard Speaks with CNBC’s “Squawk Box” Today,” CNBC, dated February 21, 2020. 3 Please see “CNBC Exclusive: CNBC Transcript: Federal Reserve Vice Chair Richard Clarida Speaks with CNBC’s Steve Liesman,” CNBC, dated February 20, 2020. 4 Please see US Bond Strategy Weekly Report, “The Credit Cycle Is Far From Over,” dated February 18, 2020, available at usbs.bcaresearch.com 5 Please see US Bond Strategy Weekly Report, “The Credit Cycle Is Far From Over,” dated February 18, 2020, available at usbs.bcaresearch.com 6 Our rationale is explained in US Bond Strategy Special Report, “The Fed In 2020,” dated December 17, 2019, available at usbs.bcaresearch.com 7 Please see US Bond Strategy Special Report, “The Fed In 2020,” dated December 17, 2019, available at usbs.bcaresearch.com 8 Governor Lael Brainard, “Federal Reserve Review of Monetary Policy Strategy, Tools, and Communications: Some Preliminary Views,” dated November 26, 2019, and “Monetary Policy Strategies and Tools When Inflation and Interest Rates Are Low,” dated February 21, 2020,  Board of Governors of the Federal Reserve System, Fixed Income Sector Performance Recommended Portfolio Specification

Special Report

Highlights Butterfly Strategy: A butterfly fixed income strategy is a combination of a barbell (a weighted combination of long- and short-term bonds) and a bullet (the medium-term bonds that sit within the yield curve segment selected in the barbell) designed to provide investors exposure to specific yield curve changes while being insulated from parallel shifts. Yield Curve Models: Simple yield curve models, based on the positive relationship between the slope of the yield curve and butterfly spreads – and to a certain extent, implied interest rate volatility – can be used to identify which part of the yield curve is most attractively valued by comparing what change in the slope is being discounted with our own macro views. Current Valuation: The overall message from our new suite of global yield curve models is that trades favoring barbells over bullets are attractive across all the developed market countries covered in our analysis. Feature In February 2002, BCA Global Fixed Income Strategy (GFIS) introduced a framework for measuring market expectations for changes in short-term interest rates embedded in the slope of government bond yield curves.1 By comparing those discounted changes with our own macro view on where rates were headed, this framework provided signals on potential value in trades focusing on the shape of the yield curve. This analysis originally focused on one specific yield curve (butterfly) strategy across six developed markets; the US, Germany, the UK, Japan, Canada, and Australia. Table 1Most Attractive Butterfly Trades More recently, our sister service US Bond Strategy applied this framework to each different butterfly spread combination across the entire US Treasury curve, creating a tool to identify the most attractively valued parts of the US yield curve at any point in time.2 In this Special Report, we revisit the original GFIS methodology for identifying attractive yield curve trades in global government bond markets. Furthermore we extend the analysis to all butterfly combinations and add three additional European countries to the list - France, Italy and Spain. The overall message is that trades that favor barbells over bullets are attractive across all the developed markets covered in this analysis. Table 1 displays the most attractive combinations of barbells over bullets for each country. Going forward, we will rely on the readings from our refreshed yield curve models, combined with our macro views, to populate our new Tactical Trade Overlay framework with yield curve trades in global government bond markets. What Is A Butterfly Strategy? A butterfly fixed income strategy involves two main components: a barbell (a weighted combination of long-term and short-term bonds) and a bullet (a medium-term bond that sits within the yield curve segment selected in the barbell). This strategy owes its name to the resemblance that barbells and bullets can have with the wings and body of an actual butterfly, not to lepidopterology.3 To implement a butterfly strategy, a bond investor would go long (short) the barbell while simultaneously going short (long) the bullet. In general, barbells are expected to outperform bullets in a flattening yield curve environment, and vice-versa. The reason butterfly strategies are so widely used is that they provide fixed-income investors exposure to specific changes in the slope of the yield curve, while being neutral to small parallel shifts. This immunization to small parallel shifts is achieved by setting the weights of the short- and long-term bonds in the barbell such that the weighted sum of their dollar duration (referred to as DV01 – the dollar value of a basis point) equals the DV01 of the bullet. In the event of large parallel shifts in the yield curve – which are quite rare – the barbell will outperform the bullet since the former will always have a greater convexity than the latter in the absence of convexity-matching between each leg of the trade. We illustrate how a 2/5/10 butterfly strategy works for US Treasuries, using hypothetical constant-maturity par bond yields, in Table 2A.4 Table 2AThe Butterfly (Strategy) Effect Illustrated As can be seen in the ”Weighted DV01” column of Table 2A, the DV01 of each leg of the trade (the bullet and the two combined bonds in the barbell) are identical. Importantly, the weighted DV01 contribution to the barbell from the 2-year note and the 10-year bond differ substantially, meaning that the barbell is more sensitive to changes in the 10-year yield than changes in the 2-year yield. This mismatch is precisely what gives a butterfly strategy exposure to the slope of the curve. Table 2A also presents three yield curve scenarios to demonstrate the benefits of butterfly strategies. In the parallel shift scenario, yields across the entire yield curve rise by 10bps. This parallel shift is neutralized as the two legs of the strategy cancel out. In the steepening curve scenario, the 2-year yield falls by 10bps, the 10-year yield rises by 10bps and the 5-year yield remains flat. In this case, the small gains on the 2-year note cannot offset the losses on the 10-year bond; hence the barbell underperforms the 7-year bullet. Finally, the “Flattening” column in the table shows that the barbell outperforms the bullet when the curve flattens. Our government bond yield curve models rely on the positive relationship typically observed between the butterfly spread and the slope of the yield curve. Bottom Line: A butterfly fixed income strategy is a combination of a barbell (a weighted combination of long- and short-term bonds) and a bullet (the medium-term bonds that sit within the yield curve segment selected in the barbell) designed to provide investors exposure to specific yield curve changes while being insulated from parallel shifts. Dusting Off The GFIS Yield Curve Models Chart 1Butterfly Spreads & Yield Curves Our government bond yield curve models rely on the positive relationship typically observed between the butterfly spread and the slope of the yield curve. When the curve steepens, the butterfly spread widens, and vice-versa (Chart 1). This has to do with mean reversion: as the curve steepens, it increases the odds that the curve will flatten in the future since it cannot steepen indefinitely. Consequently, investors will ask for greater compensation to enter a curve steepener trade when the curve is already steepening. As a result, we can create simplified models of the yield curve by regressing any butterfly spread on its corresponding curve slope. Deviations from these fair value models indicate which butterfly strategies are cheap or expensive. While positive, the correlations between yield curve slopes and butterfly spreads vary widely across butterfly combinations and also among countries – in Japan, for example, the historical relationship seems dubious (Chart 1, panel 4). We can further improve the fit of some of our yield curve models by including the MOVE US bond volatility index as a second independent variable. As our colleagues at US Bond Strategy have pointed out, implied interest rate volatility is also positively correlated with the slope of the yield curve (Chart 2, top panel). This matters for butterfly trades because of the convexity mismatch between the barbell and the bullet, particularly given the fact that high convexity is beneficial when implied interest rate volatility is elevated. Simply put, a larger convexity mismatch between the two legs makes them more sensitive to changes in the slope of the curve, and therefore easier to model (Chart 2, bottom panel). Importantly, one other useful application of the relationship between yield curve slopes and butterfly spreads is that we can reverse the yield curve models to calculate what amount of curve steepening or flattening is being discounted in current butterfly spreads. In other words, our models allow us to calculate change in the curve slope that would force the butterfly spread to be equal to its fair value (Chart 3). Chart 2Taking Into Account Implied Vol Armed with that information, we can then apply our macro views to determine potential butterfly spread trades. Chart 3Case In Point: US 2/5/10 Spread Fair Value Model For example, the 2/5/10 butterfly spread in the US (the 5-year bullet yield minus the weighted combination of 2-year and 10-year yields) is, at the moment, below its fair value with 46bps of steepening discounted over the next six months (Chart 3, panels 2 & 3). That means the bullet is expensive as per our model and therefore the recommended butterfly strategy would be to go long the 2/10 barbell and short the bullet. However, in the event the 2/10 Treasury slope steepens by more than 46bps over the next six months, the 5-year bullet would be expected to outperform the barbell. In other words, when the butterfly is initially below its fair value, more curve steepening will be needed for the bullet to outperform the barbell. Conversely, if it is above fair value, more curve flattening will be required for the barbell to outperform. In light of this, let’s consider the example of curve steepening from before, but this time looking at two scenarios: the butterfly spread is at fair value the butterfly spread is initially different from its model-implied fair value, but is then expected to revert to fair value by the end of the investment horizon. Under the first scenario, the bullet outperforms the barbell when the curve steepens, as expected given that the butterfly spread is at fair value (Table 2B). Now, in the second scenario, the bullet actually ends up underperforming the barbell, although it is the same curve steepening environment. Table 2BButterfly Strategy Performance And Deviations From Model-Implied Fair Values The reason for this underperformance is that the butterfly spread is now below the fair value shown in scenario #1, thus requiring more steepening for the bullet to outperform the barbell. Ultimately, we have to rely on our macro view of how the slope of the yield curve will change alongside the message from our yield curve models to choose the right butterfly strategy. This means that, ultimately, we have to rely on our macro view of how the slope of the yield curve will change alongside the message from our yield curve models to choose the right butterfly strategy. Bottom Line: Simple yield curve models, based on the positive relationship between the slope of the yield curve and butterfly spreads – and to a certain extent, implied interest rate volatility – can be used to identify which part of the yield curve is most attractively valued by comparing what change in the slope is being discounted with our own macro views. The Message From Our Butterfly Strategy Valuations In the remaining pages of this Special Report, we present the current read-outs from of our yield curve models for each of the major developed market. More specifically, we provide the deviations from fair value for different combinations of bullets and barbells and highlight the most attractive butterfly strategy. The deviations from fair value shown in Tables 3-11 are standardized to facilitate comparison between the different butterfly combinations. Also, for each country we provide a quick assessment of the performance of these butterfly strategies over time by applying a simple mechanical trading rule. Every month, we enter the most attractive butterfly strategy, i.e. the one with the highest absolute standardized deviation from its model fair value. The overall message is that barbells appear attractive relative to bullets across all the countries shown. Trades that favor barbells over bullets are attractive across all the developed markets covered in our analysis. This is consistent with our near term macro view. Global government bond markets have been experiencing bull flattening pressures ever since the COVID-19 virus outbreak sparked a generalized flight-to-safety. Markets woke up to the recent news about the spread of the virus in countries outside of China – namely Italy, South Korea, Japan, Iran and Israel – and all traces of complacency have now vanished.5 There is too much uncertainty about COVID-19 in terms of severity and duration, and government bond yields may very well continue falling until the threat is contained. In the meantime, this may force major central banks to provide even easier monetary policy. While this may be difficult for the ECB and the BoJ, which both already seem out of ammunition, the other central banks could very well end up delivering the rate cuts currently discounted in the overnight index swap curves.6 Looking back at our Central Bank Discounters, the largest amount of rate cuts over the next year are now discounted in the US (-53bps), now discounted in the US (-53bps), Australia (-38bps), Canada (-37bps) and the UK (-23bps). At the same time, the fewest cuts are priced in Japan (-8bps), the euro area (-6bps) and New Zealand (-25bps). The resulting bull steepening would likely be mild, however; after all, rate cuts cannot fight a pandemic, but can only try and cushion the blow to growth. In the event COVID-19 virus does not turn into a pandemic and we observe a decline in the daily change of the number of cases, then global government bond yields would rebound from their current lows. Given the current valuation cushion, we would expect barbelled portfolios to do well, especially since we would not expect more steepening than what is currently being discounted (i.e. we do not expect the 2/30 Treasury slope to steepen by more than 73bps in the near term).   Jeremie Peloso Senior Analyst jeremiep@bcaresearch.com US There are presently three butterfly combinations standing out in that they appear attractive according to our yield curve model. One of them is going long the 2/30 barbell and shorting the 10-year bullet, which currently displays a standardized residual of -1.42 (Table 3). Table 3US: Butterfly Strategy Valuation: Standardized Residuals The bullet appears 21bps expensive according to our model and would only outperform its counterpart given a steepening in the 2/30 Treasury slope greater than 73bps, which we view as unlikely given the current environment (Chart 4A). Chart 4AUS: 2/10/30 Spread Fair Value Model Chart 4BUS Butterfly Strategy Performance Following the mechanical trading rule looks promising (Chart 4B). In fact, we observe few periods of negative year-over-year returns. Germany The most attractively valued butterfly combination currently on the German yield curve is going long the 2/30 barbell and shorting the 10-year bullet, which is currently a little bit more than one standard deviation above its implied-model fair value, with a standardized residual of -1.09 (Table 4). Table 4Germany: Butterfly Strategy Valuation: Standardized Residuals The bullet appears 14bps expensive according to our model and would only outperform its counterpart given a steepening in the 2/30 German curve slope greater than 36bps (Chart 5A). Chart 5AGermany: 2/10/30 Spread Fair Value Model Chart 5BGerman Butterfly Strategy Performance Over time, picking the cheapest butterfly combinations based on our yield curve models works relatively well (Chart 5B). Importantly, we observe very few episodes of underperformance since 1990. France The most attractively valued butterfly combination currently on the French OAT yield curve is going long the 5/30 barbell and shorting the 10-year bullet, which currently displays a standardized residual of -1.13 (Table 5). Table 5France: Butterfly Strategy Valuation: Standardized Residuals The 10-year bullet appears 11bps expensive according to our model and would only outperform its counterpart given a steepening in the 5/30 French OAT curve slope greater than 44bps (Chart 6A). Chart 6AFrance: 5/10/30 Spread Fair Value Model Chart 6BFrench Butterfly Strategy Performance The mechanical trading rule appears to also work relatively well when applied to butterfly combinations in the French OAT government bond market (Chart 6B). Italy & Spain Turning to European countries in the periphery, the most attractively valued butterfly combinations appear to be going long the 5/30 barbell and shorting the 7-year bullet in the Italian government bond yield curve (Table 6), and favoring the 7/30 barbell versus the 10-year bullet in the Spanish government bond market (Table 7). Table 6Italy: Butterfly Strategy Valuation: Standardized Residuals Table 7Spain: Butterfly Strategy Valuation: Standardized Residuals In the case of Italy, the 7-year bullet appears 7bps expensive according to our model and would only outperform its counterpart given a steepening in the 5/30 Italian curve slope greater than 41bps (Chart 7A). The mechanical trading rule appears to work well when applied to Italian butterfly combinations, displaying better excess returns than for most other countries we’ve looked at (Chart 7B). Chart 7AItaly: 5/7/30 Spread Fair Value Model Chart 7BItalian Butterfly Strategy Performance Looking at Spain, the 10-year bullet appears 8bps expensive according to our model and would only outperform its counterpart given a steepening in the 7/30 Spanish curve slope greater than 64bps, which seems highly unlikely at this point in time (Chart 8A). The mechanical trading rule works well when applied to Spanish butterfly combinations and shows very few periods of underperformance since the early 90s (Chart 8B). Chart 8ASpain: 7/10/30 Spread Fair Value Model Chart 8BSpanish Butterfly Strategy Performance UK The most attractively valued butterfly combination currently on the UK Gilts yield curve is holding a 2/30 barbell versus the 10-year bullet, which currently displays a standardized residual of -1.64 (Table 8). Table 8UK: Butterfly Strategy Valuation: Standardized Residuals The 10-year bullet appears 21bps expensive according to our model and would only outperform its counterpart given a steepening in the 2/30 curve slope greater than 62bps (Chart 9A). Chart 9AUK: 2/10/30 Spread Fair Value Model Chart 9BUK Butterfly Strategy Performance Chart 9B shows that applying the simple mechanical trading rule works well over time. Canada The most attractively valued butterfly combination currently on the Canadian yield curve is favoring a 1/30 barbell versus the 10-year bullet, which currently displays a standardized residual of -1.11 (Table 9). Table 9Canada: Butterfly Strategy Valuation: Standardized Residuals The 10-year bullet appears 18bps expensive according to our model and would only outperform its counterpart given a steepening in the 1/30 curve slope greater than 60bps (Chart 10A). Chart 10ACanada: 1/10/30 Spread Fair Value Model Chart 10BCanadian Butterfly Strategy Performance Once more, following the mechanical trading rule looks promising (Chart 10B). In fact, we observe only four periods of negative year-over-year returns. Japan The most attractively valued butterfly combination currently on the Japanese JGBs yield curve is going long the 5/10 barbell and shorting the 7-year bullet, which is currently below one standard deviation above its implied-model fair value, with a standardized residual of only -0.86 (Table 10). Table 10Japan: Butterfly Strategy Valuation: Standardized Residuals The bullet appears slightly expensive, by 5bps, and would only outperform its counterpart given a steepening in the 5/10 JGB curve slope greater than 32bps (Chart 11A). Chart 11AJapan: 5/7/10 Spread Fair Value Model Chart 11BJapanese Butterfly Strategy Performance The mechanical trading rule also performs well when selecting the most attractive butterfly combinations in the Japanese government bond market (Chart 11B). Australia The most attractively valued butterfly combination currently on the Australian government bond yield curve is going long the 3/10 barbell and shorting the 7-year bullet, which presently displays a standardized residual of -1.52 (Table 11). Table 11Australia: Butterfly Strategy Valuation: Standardized Residuals Please note that we excluded the 20- and 30-year government bonds from our analysis since they were first issued only a few years ago. Our yield curve model suggests that the bullet is 10bps expensive and would only outperform its counterpart given a steepening in the 3/10 Australian curve slope greater than a whopping 92bps (Chart 12A).
