Highlights Fed/BoE NIRP: It is too soon for either the Fed or Bank of England to consider a move to a negative interest rate policy (NIRP), even with US and UK money markets flirting with pricing in that outcome. Lessons from “NIRP 1.0”: In the countries that did go to negative rates in 2014-16 (Japan, Switzerland, the euro area, Sweden and Denmark), there existed some combination of weak economies, near-0% inflation, anemic credit growth or unwanted currency appreciation. Negative rates were needed to help fight those trends by driving down longer-term bond yields. NIRP 2.0?: Among the major countries without negative rate policies in effect (the US, UK, Canada and Australia), there is no evidence that longer-term borrowing rates need to fall further to boost credit growth, even in the midst of deep recessions. However, additional strength of the stubbornly resilient US dollar could be the deflationary shock that eventually forces the Fed into NIRP. Feature Chart 1NIRP 2.0 Would Trigger A Surge Of Negative Yielding Bonds Within a 20-month window in 2014-16, the central banks of Japan, Sweden, the euro area, Switzerland and Denmark all cut policy interest rates to below 0% - where they remain to this day. Fast forward to 2020, in the midst of a global pandemic and deep worldwide recession that has already forced major developed market central banks to cut rates close to 0%, there is now increased speculation that the negative interest rate policy (NIRP) club might soon get a few new members. The Federal Reserve has been front and center in that group. Fed funds futures contracts had recently priced in slightly negative rates in 2021, despite Fed Chair Jerome Powell repeatedly saying that a sub-0% funds rate was not in the Fed’s plans. The Bank of England (BoE) has also seen markets inch toward pricing in negative rates, although BoE officials have been more open to the idea of negative rates as a viable policy choice. Even the Reserve Bank of New Zealand has suggested that negative rates may be needed there soon. An expansion of the list of countries that have moved to negative rates, beyond the “NIRP 1.0” group of 2014-16, has the potential to drive down global bond yields even further. Already, there is $11 trillion of negative yielding debt within the Bloomberg Barclays Global Aggregate index, representing 20% of the total (Chart 1) If there is a shift to negative rates in the potential “NIRP 2.0” group of major developed economies with policy rates now near 0% – a list that includes the US, the UK, Canada and Australia – then the amount of negative yielding debt worldwide will soar to new highs. An expansion of the list of countries that have moved to negative rates, beyond the “NIRP 1.0” group of 2014-16, has the potential to drive down global bond yields even further. In this report, we take a look at the conditions that led the NIRP 1.0 countries to shift to negative rates in the middle of the last decade, to see if any similarities exist in non-NIRP countries today. We conclude that the conditions are not yet in place for a shift to sub-0% policy rates in the US, the UK, Canada or Australia – all countries where central banks still have other policy tools available to provide stimulus before resorting to negative rates. How Negative Interest Rates Can “Work” To Revive Growth Broadly speaking, central banks around the world have had difficulty meeting their inflation targets since the 2008 Global Financial Crisis. The main reason for this has been sub-par economic growth, much of which is structural due to aging demographics and weak productivity. Since central bankers must stick to their legislated inflation targeting mandates, they are forced to cut rates when economic growth and inflation are too low. If real economic growth remains weak for structural reasons, then central banks can enter into a cycle of continually cutting rates all the way to zero, or even below zero, in order to try and prevent low inflation from becoming entrenched into longer-term inflation expectations. If growth and inflation continue to languish even after policy rates have reached 0%, then other tools must be used to ease monetary conditions to try and stimulate economies. These typically involve driving down longer-term borrowing rates (bond yields) through dovish forward guidance on future monetary policy, bond purchases through quantitative easing (QE) and, if those don’t work, moving to negative policy interest rates. A nice summary indicator to identify this intertwined dynamic of real economic growth and inflation is to look at the trend growth rate of nominal GDP. Chart 2 shows the policy interest rates three-year annualized trend of nominal GDP growth for the NIRP 1.0 countries, dating back to before the 2008 crisis. Japan stands out as the weakest of the group, with trend nominal growth contracting during and after the 2009 recession, while struggling to reach even +2% since then. The euro area, Sweden and Switzerland all enjoyed +5% nominal growth prior to 2008, before a plunge to the 1-2% range during and after the recession. After that, the three countries had varying degrees of economic success. Between 2016 and 2019, Sweden saw trend nominal growth between 4-5%, while the euro area struggled to achieve even +3% nominal growth and Switzerland maintained a Japan-like pace. Chart 2Fewer Tools Left For NIRP 1.0 Countries To Boost Growth Chart 3NIRP 2.0 Candidates Can Still Expand QE First The European Central Bank (ECB), Swiss National Bank (SNB), the Bank of Japan (BoJ) and Sweden’s Riksbank all cut policy rates aggressively in 2008/09, helping spur a recovery in nominal growth. The central banks had to keep rates lower for longer because of structurally weak growth, leaving far less capacity to ease aggressively in response to the growth downturn a few years later. Eventually, the ECB, SNB, BoJ and Riksbank all went to negative rates between June 2014 and February 2016. The BoJ and SNB, facing persistent headwinds from strengthening currencies, also resorted to aggressive balance sheet expansion to provide additional monetary stimulus – trends that have continued to this day, with both central banks having balance sheets equal to around 120% of GDP. The experience of these four NIRP 1.0 countries showed that the move to negative rates was a process that began in the 2008 financial crisis. Central banks there were unable to raise rates much, if at all, after the recession, leaving little ammunition to fight the varying growth slowdowns suffered between 2012 and 2016. Eventually, rates had to be cut below 0% which, combined with QE, helped generate lower bond yields, weaker currencies and, eventually, a pickup in growth and inflation. Looking at the NIRP 2.0 candidate countries, nominal GDP growth has also struggled since the financial crisis, unable to stay much above 3-4% in the US, Canada and the UK. Only Australia has seen trend growth reach peaks closer to 5-6% (Chart 3). The Fed, BoE, Reserve Bank of Australia (RBA) and Bank of Canada (BoC) all also cut rates aggressively in 2008/09, with the Fed and BoE doing QE buying of domestic bonds. Rates were left at low levels after the crisis in the US and UK, with only the RBA and, to a lesser extent, the BoC hiking rates after the recession ended. When growth slowed again in these countries during the 2014-16 period, the RBA and BoC did lower policy rates, but negative rates were avoided by all four central banks. Today, nominal growth rates have collapsed because of the COVID-19 lockdowns that have shuttered much of the world economy. Central banks that have had any remaining capacity to cut policy rates back to 0% have done so, yet this recession has already become so deep that additional declines in rates may be necessary to stabilize unemployment and inflation. The experience of the NIRP 1.0 countries shows that negative rates can also be effective in boosting growth – especially in countries suffering unwanted currency strength. One way to see the problem that monetary policymakers are now facing is by looking at Taylor Rule estimates of appropriate interest rate levels (Charts 4 and 5). Given the rapid surge in global unemployment rates to levels that, in some cases, have not been seen since the Great Depression (Chart 6), alongside decelerating inflation, Taylor Rule implied policy rates are now deeply negative in the US (-5.6%), Canada (-2.9%) and euro area (-1.7%).1 Taylor Rules show that moderately negative rates are also needed in Sweden (-0.5%), Switzerland (-0.2%) and Japan (-0.2%). Only in Australia (+1.3%) and the UK (+0.3%) is the Taylor Rule indicating that negative rates are not currently required. Chart 4Taylor Rule Says More Rate Cuts Needed Here … Chart 5… But Rates Are Appropriate Here Chart 6The Main Reason Why Taylor Rule Implied Policy Rates Have Plunged Among the potential NIRP 2.0 candidates, the negative rate option has been avoided and aggressive QE balance sheet expansion has been pursued by all of them – including the BoC and RBA who avoided asset purchase programs in 2008/09. Balance sheet expansion can be an adequate substitute for policy interest rate cuts by helping drive down longer-term bond yields and borrowing rates, which helps spur credit demand and, eventually, economic growth. Yet the experience of the NIRP 1.0 countries shows that negative rates can also be effective in boosting growth – especially in countries suffering unwanted currency strength. How negative rates worked for the NIRP 1.0 countries For the ECB (Chart 7), BoJ (Chart 8), Riksbank (Chart 9) and SNB, the path from negative policy rates in 2014-16 to, eventually, faster economic growth and inflation followed a similar process: Chart 7The Euro Area's Negative Rates Experience Chart 8Japan's Negative Rates Experience Chart 9Sweden's Negative Rates Experience Moving to negative policy rates resulted in a sharp decline in nominal government bond yields The fall in yields helped trigger currency depreciation Nominal yields fell faster than inflation expectations, allowing real bond yields to turn negative Credit growth eventually began to pick up in response to the decline in real borrowing costs Inflation bottomed out and started to move higher. In Japan, the euro area and Sweden, this process played out fairly rapidly with credit growth and inflation bottoming within 6-12 months of the move to negative rates. Only in Switzerland (Chart 10), where the SNB gave up on currency intervention in January 2015, was the process delayed, as the surge in the currency triggered a move into deeper deflation and higher real bond yields. It took a little more than a year for the deflationary impact of the franc’s surge to fade, allowing real bond yields to decline and credit growth and inflation to bottom out and recover. The implication is clear – negative rates are good for real assets, but troublesome for banks. Of course, we are talking about the pure economic effect of negative rates as a monetary policy tool. There are side effects of having negative nominal interest rates and deeply negative real bond yields, like surging asset values (especially for real assets like housing). Bank profitability is also negatively impacted by the sharp fall in longer-term bond yields that hurts net interest margins, even with higher lending volumes and reduced non-performing loans. Chart 10Switzerland's Negative Rates Experience Chart 11Negative Rates Are Good For Real Assets This can be seen in Charts 11 & 12, which compare the performance of real house prices and bank equities (relative to the domestic equity market) in the years leading up to, and following, the move to negative rates in 2014-16 for the NIRP 1.0 countries. The implication is clear – negative rates are good for real assets, but troublesome for banks. Chart 12Negative Rates Are Bad For Bank Stocks Nonetheless, the experience of the NIRP 1.0 countries suggests that the potential NIRP 2.0 countries could see similar benefits on growth and inflation – but not before other policy options are exhausted first. Bottom Line: In the countries that did go to negative rates in 2014-16 (Japan, Switzerland, the euro area, Sweden and Denmark), there existed some combination of weak economies, near-0% inflation, anemic credit growth or unwanted currency appreciation. Negative rates were needed to help fight those trends by driving down longer-term bond yields and helping spur credit growth and, eventually, some inflation. Depreciating currencies had a big role to play in generating those outcomes. Negative Rates Are Not Necessary (Yet) In The NIRP 2.0 Countries As discussed earlier, the sharp surge in unemployment because of the COVID-19 global recession means that negative interest rates may now be “appropriate” in the US and Canada, based on Taylor Rules. Negative rates are not needed in the UK and Australia, however, although policy rates need to stay very low in both countries. A similar divergence can be seen in inflation. Headline CPI inflation rates were already under severe downward pressure from the recent collapse in oil prices. The surge in spare economic capacity opened up by the current recession can only exacerbate the disinflation trend. However, the drop in inflation has been more acute in the US and Canada relative to the UK and Australia, suggesting a greater need for the Fed and BoC to be even more stimulative than the BoE or RBA (Chart 13). A renewed breakout of the currency to new cyclical highs could be the deflationary signal that triggers the Fed into an even more aggressive policy response. There is one area where the Fed stands alone in this group. The relentless strength of the US dollar, even as the Fed’s rate cuts have taken much of the attractive carry out of the greenback, hurts US export competitiveness in a demand-deficient recessionary global economy. The strong dollar also acts as a dampening influence on US inflation. A renewed breakout of the currency to new cyclical highs could be the deflationary signal that triggers the Fed into an even more aggressive policy response (Chart 14). This would mirror the experience of the NIRP 1.0 countries prior to the move to negative rates, where unwanted currency strength crippled both economic growth and inflation. Chart 13The Threat Of Deflation Could Trigger NIRP Chart 14Could More USD Strength Drag The Fed Into NIRP? For now, the Fed has many other policy options open before negative rates would be seriously considered. The reach of its QE programs could be expanded even further, even including equity purchases. The existing bond QE could be combined with a specific yield target (i.e. yield curve control) for shorter-maturity US Treasuries, helping anchor US yields at low levels for longer. Summing it all up, we do not see the need for any of the NIRP 2.0 candidates to move to negative rates anytime soon. The need for such extreme policies is not yet necessary, though, both in the US and the other NIRP 2.0 candidate countries. Bank lending is expanding at a double-digit pace in the US, and still at a decent 5-7% pace in the UK, Canada and Australia, even in the midst of a sharp recession (Chart 15). This may only be due to the numerous loan guarantees provided by governments as part of fiscal stimulus responses, or it may be related to companies running down credit lines to maintain liquidity. The experience of the NIRP 1.0 countries, though, suggests that credit growth must be far weaker than this to require negative policy rates to push down longer-term borrowing costs. Chart 15These Already Look Very "NIRP-ish" Chart 16Too Soon For Global NIRP, Maintain Neutral Global Duration Exposure Summing it all up, we do not see the need for any of the NIRP 2.0 candidates to move to negative rates anytime soon. In terms of investment implications, we continue to recommend an overall neutral stance on global duration exposure, as we see little immediate impetus for yields to move lower because of reduced expectations of future interest rates or inflation (Chart 16). We will continue to watch currency levels and credit growth as a sign that policymakers may need to shift their tone in the coming months. Bottom Line: Among the major countries without negative rate policies in effect (the US, UK, Canada and Australia), there is no evidence that longer-term borrowing rates need to fall further to boost credit growth, even in the midst of deep recessions. However, additional strength of the stubbornly resilient US dollar could be the deflationary shock that eventually forces the Fed into NIRP.

The Custom Benchmark Index Footnotes 1 Our specification of the Taylor Rule uses unemployment rates relative to full employment (NAIRU) levels as the measure of spare capacity in the economies. For the neutral real interest rate, we use the New York Fed’s estimate of r-star for the US, Canada, the euro area and the UK; while using the OECD’s estimate of potential GDP growth as the neutral real rate measure for countries where we have no r-star estimate (Japan, Sweden, Switzerland and Australia).
