Executive Summary Spreads Near 2017-19 Average The main indicators that determine corporate bond performance are valuation, the cyclical/monetary environment and corporate balance sheet health. US corporate bond valuation is quite expensive. Spreads are off their post-COVID lows, but consistent with the 2017-19 average. The flat 2-year/10-year Treasury curve indicates that the cyclical/monetary backdrop is relatively poor. What’s more, the yield curve could easily invert within the next few months as the Fed tightens. This would send an even more negative signal for corporate bond returns. Corporate balance sheets are currently in excellent shape, but their health will deteriorate within the next 12 months as profit growth slows and interest rates rise. Relative valuation favors high-yield over investment grade corporates, and high-yield has a track record of outperformance during periods of restrictive monetary conditions and strong corporate balance sheets. Bottom Line: Investors should cyclically reduce exposure to US corporate bonds while retaining a preference for high-yield over investment grade. We recommend downgrading investment grade corporates from neutral (3 out of 5) to underweight (2 out of 5) and high-yield corporates from overweight (4 out of 5) to neutral (3 out of 5). Feature Chart 1A Rapid Recovery US corporate bonds have had a very good run since the March 2020 peak in spreads. Investment grade corporates outperformed a duration-matched position in US Treasuries by 23% during the first 12 months of the recovery, the best 12-month excess return since 2010 (Chart 1). That same period also saw an extremely rapid re-normalization of credit spreads. It took just 11 months for the investment grade corporate index option-adjusted spread (OAS) to reach 90 bps following its March 2020 peak, and the index delivered an annualized excess return of 26% during that period. In contrast, it took 109 months for the index OAS to reach 90 bps following the 2008 recession and corporates only beat duration-matched Treasuries by an annualized 4% during that time (Table 1). Table 1US Investment Grade Corporate Bond Returns From Spread Peak Until 90 BPs The outlook for US corporate bond returns looks much different today. Spreads are tighter and the Fed is rapidly removing policy accommodation. Against this backdrop, we decided last week to cyclically reduce our corporate bond exposure.1 Specifically, we recommended downgrading investment grade corporates from neutral (3 out of 5) to underweight (2 out of 5) and high-yield corporates from overweight (4 out of 5) to neutral (3 out of 5) within US bond portfolios. This Special Report discusses the rationale for our recent decision. First, we examine trends in the main indicators that determine corporate bond performance. These indicators fall into three categories: (i) valuation, (ii) cyclical/monetary indicators and (iii) balance sheet health. We then discuss the outlook for the relative performance of high-yield versus investment grade corporates. Valuation Starting with a simple examination of the average investment grade index OAS, we see that the spread has widened somewhat off its pre- and post-pandemic lows, but remains close to the average level seen between 2017 and 2019 (Chart 2). The index OAS is a reasonable gauge of value relative to recent history, but for a longer historical perspective we should adjust the index to account for its changing average credit rating and duration. To do this, we first re-weight the index to maintain a constant distribution between the different credit rating buckets. Next, we control for the index’s changing duration by calculating a 12-month breakeven spread. The 12-month breakeven spread is the spread widening that must occur during the next 12 months for the corporate index to perform in line with a duration-matched position in Treasuries. It can be approximated by dividing the index OAS by average index duration. Finally, Chart 3 presents the 12-month breakeven spread as a percentile rank since 1995. It shows that, after controlling for credit rating and duration, the investment grade corporate index has only been more expensive than current levels 24% of the time since 1995. Notice that the spread bounced off the 0% line in late-2021, indicating that it had reached all-time expensive levels. Chart 2Spreads Near 2017-19 Average Chart 3Investment Grade Valuation All in all, we can conclude that investment grade corporate bonds are quite expensive. Spreads aren’t so low that they would justify an underweight allocation in a supportive cyclical/monetary environment. But they are tight enough that it makes sense to proceed cautiously in a neutral or negative cyclical/monetary environment, like the one we are in today. Cyclical/Monetary Indicators The slope of the yield curve is the key variable we use to assess the current state of the cyclical/monetary environment. A very flat or inverted yield curve signals a relatively restrictive monetary policy backdrop, and we have shown that such a backdrop tends to coincide with poor excess corporate bond returns. Conversely, we have found that corporate bonds perform best early in the economic recovery when the yield curve is very steep. This steep yield curve signals that monetary conditions are highly accommodative, and thus supportive of credit spread tightening. Today, the yield curve is sending a somewhat confusing message. The 2-year/10-year Treasury slope briefly inverted last week, and it remains flat at 22 bps. Meanwhile, the 3-month/10-year Treasury slope is very steep, up above 200 bps (Chart 4)! Chart 4Conflicting Signals From The Yield Curve We discussed how to interpret the signals from different yield curve segments in a recent Special Report.2 We found that the 2-year/10-year Treasury slope sends the most useful signal for corporate bond excess returns, and we therefore view current cyclical/monetary conditions as negative for corporate bonds. In Table 2 we split each of the past six economic cycles into phases based on the 2-year/10-year Treasury slope. We define Phase 1 of the cycle as the period from the end of the prior recession until the 2-year/10-year slope breaks below 50 bps. Phase 2 of the cycle encompasses the time when the slope is between 0 bps and 50 bps. Phase 3 of the cycle spans from when the yield curve inverts until the start of the next recession. Table 2US Corporate Bond Performance In Different Phases Of The Cycle The table shows annualized excess returns for both investment grade and high-yield corporate bonds in each of the three phases, and those returns exhibit a clear pattern. Returns are best in Phase 1 when the yield curve is steep. They take a step down in Phase 2 when the slope is between 0 bps and 50 bps, though they usually stay positive. Negative returns are most likely in Phase 3, after the yield curve inverts. Chart 5Limited Room For Curve Steepening With the 2-year/10-year Treasury slope at 22 bps, we are firmly in Phase 2 of the cycle. However, we could easily see the 2-year/10-year slope invert within the next few months while a breakout above 50 bps seems less likely. In fact, there are only two ways in which the 2-year/10-year Treasury slope can steepen further from current levels. First, the market could bid up its expectation of the long-run neutral fed funds rate, pushing long-dated bond yields higher. Second, expectations for the pace of near-term Fed tightening could diminish, pulling short-dated yields down. At the long-end, the 5-year/5-year forward Treasury yield is already above survey estimates of the long-run neutral rate (Chart 5). At the front-end, the market is discounting a rapid pace of 272 bps of tightening during the next 12 months (Chart 5, bottom panel), but that pace has limited room to fall given current extremely high inflation readings. Turning back to a comparison of the signals from the 2-year/10-year slope and 3-month/10-year slope, it is worth pointing out that the 3-month/10-year slope is influenced by yield movements at the very front-end of the curve. Meanwhile, the 2-year/10-year slope is purely a function of rate expectations beyond the next two years. As a result, we can view the 3-month/10-year slope as sending a timelier signal about Fed rate hikes and cuts, while the 2-year/10-year slope gives a better reading of how the market views the ultimate economic impact of Fed actions. For example, the 3-month/10-year Treasury slope inverted in 2019 just before the Fed started cutting rates (Chart 6A). The 2-year/10-year slope, however, only briefly dipped below zero. The message from the market was that the Fed would cut rates, but those cuts would be sufficient to sustain the economic recovery. As a result, corporate bonds performed well during this period, consistent with the message from the 2-year/10-year slope. Another interesting example occurred in early 2000 (Chart 6B). This time, the 2-year/10-year Treasury slope inverted while the 3-month/10-year slope remained steep. In this case, the 3-month/10-year slope was telling us that Fed rate hikes would continue, while the 2-year/10-year slope was telling us that those hikes would eventually kill the economic recovery. Once again, corporate bonds took their cues from the 2-year/10-year Treasury slope and performed poorly during this period. Chart 6AStrong Performance In 2019 Chart 6BPoor Performance In 2000 Obviously, the current situation looks more like 2000 than 2019, but with the 2-year/10-year slope still positive there remains scope for positive excess corporate bond returns in the near-term. That said, with high odds of 2-year/10-year curve inversion within the next few months and spreads at relatively tight levels, it makes sense to scale back exposure today in advance of the worst phase of the cycle. Balance Sheet Health The final factor we consider is the health of nonfinancial corporate sector balance sheets, and in fact, this is currently the lone bright spot for corporate bond investors. Our Corporate Health Monitor (CHM), a composite indicator of six key balance sheet ratios, is deep in “improving health” territory (Chart 7). This positive signal is driven by exceptionally high Interest Coverage (Chart 7, panel 2) and Free Cash Flow-To-Debt that is just off its highs (Chart 7, panel 3). Return On Capital is up sharply since 2020 but has not recovered its previous peak (Chart 7, bottom panel). Chart 7Balance Sheets Are In Great Shape While corporate balance sheets are in excellent shape right now, their health will certainly deteriorate going forward as profit growth comes down off its highs and interest rates rise. The only question is whether this deterioration will happen slowly or quickly. Turning to history, two relevant periods stand out (Chart 8). First is the mid-1990s when investment grade corporate bond excess returns peaked in July 1997, 16 months before our CHM moved into “deteriorating health” territory. Conversely, the CHM sent a negative signal before the excess return peak in 2007. But even then, investment grade corporates only outperformed Treasuries by an annualized 0.8% between when the 2-year/10-year slope fell below 50 bps in 2005 and when the CHM moved above zero in 2006. In other words, investors didn’t sacrifice much return by heeding the yield curve’s signal even when the CHM was deep in “improving health” territory. Chart 8Cyclical Corporate Bond Performance Investment Conclusions In summary, we view corporate bond valuations as expensive, and the flat 2-year/10-year Treasury slope suggests that the economic recovery is in its mid-to-late stages. Corporate balance sheets are currently in excellent shape, but they will deteriorate going forward as profit growth slows and interest rates rise. The above three factors suggest that corporate bonds could continue to outperform duration-matched Treasuries in the near-term. However, with spreads already at tight levels, we likely aren’t sacrificing much in the way of excess returns by turning cyclically defensive today. This move also ensures that we will not be invested when the credit cycle eventually turns and corporate bond spreads move significantly wider. Retain A Preference For High-Yield Versus Investment Grade While we recommend downgrading allocations for both investment grade (from neutral to underweight) and high-yield (from overweight to neutral), we think investors should still retain a preference for high-yield corporates over investment grade. To see why, let’s return to the 2005-06 period we looked at in the previous section. The yield curve dipped below 50 bps in 2005 when the CHM was still deep in “improving health” territory, and while investment grade corporate bond returns were low during the time between the signal from the yield curve and the signal from the CHM, junk excess returns were very strong (Chart 9). This makes some sense intuitively. Higher-rated investment grade corporates responded negatively to the Federal Reserve’s removal of monetary policy accommodation, but lower-rated junk spreads stayed well bid because actual default risk was benign. It wasn’t until after the CHM rose above zero that junk bonds started to underperform. In terms of present-day valuations, much like for investment grade, junk spreads are up off their 2021 lows. However, they remain close to their pre-pandemic trough (Chart 10). We also note that the differential between high-yield and investment grade spreads was much tighter in 2006-07. Given the similarities between that period and today, we wouldn’t be surprised to see junk spreads compress further relative to investment grade. Chart 9The Bullish Case For Junk Chart 10High-Yield Valuation Another way to approach high-yield bond valuation is through the lens of our Default-Adjusted Spread. The Default-Adjusted Spread is the difference between the junk index OAS and 12-month default losses, and we have shown that it has a strong correlation with excess returns (Table 3). Specifically, a Default-Adjusted Spread above 100 bps usually coincides with positive excess junk returns versus Treasuries, and higher spreads tend to coincide with higher returns. Table 3The Default-Adjusted Spread & High-Yield Excess Returns To estimate the Default-Adjusted Spread for the next 12 months we need assumptions for the default and recovery rates (Chart 11). To do this, we model the 12-month speculative grade default rate as a function of gross nonfinancial corporate leverage – total debt over pre-tax profits – and lagged C&I lending standards. We then model the 12-month recovery rate based on the default rate itself. Chart 11Default And Recovery Rate Models Corporate pre-tax profit growth was exceptionally strong during the past 12 months, and we expect it to slow significantly going forward. Profit growth can be modeled as a function of nominal GDP growth and unit labor costs (Chart 12). If we assume that nominal GDP growth comes in at 7.3% this year (the Fed’s median 2.8% real GDP estimate plus 4.5% inflation) and that unit labor cost growth rises to 6%, then profit growth will fall to 0.5% during the next 12 months. If we assume that corporate debt growth remains close to its current level (Chart 12, bottom panel), then we calculate that gross leverage will rise to 6.5 during the next 12 months. Chart 12Profit Growth Will Slow Significantly Table 4 shows the output from our default and recovery rate models under the base case assumption described above. It also shows results for an optimistic case where leverage is 6.0 and a pessimistic case where it is 7.0. The Default-Adjusted Spread is fairly low in the base and pessimistic cases, but it is comfortably above the key 100 bps threshold in all three scenarios. This suggests that junk bonds should deliver positive excess returns versus duration-matched Treasuries during the next 12 months.
