The standard sixty-forty portfolio garnered double-digit returns in 2020 for only the seventh time in the past 20 years. While this also marked the first back-to-back calendar year of double-digit returns since 1999,1 the victory lap didn’t last long. The bond market hasn’t kept up the pace in 2021.
In fact, in February with rates rising, the only broad-based fixed income sectors with positive returns for the month – and for the year – were high yield and senior loans. All other sectors have stumbled out of the box due to duration-induced price declines and the opposite reaction bond prices have when rates rise.
Fueled by accommodative monetary policies and additional fiscal stimulus, higher inflation expectations and upbeat growth prospects will likely keep upward pressure on rates – and, therefore, weigh on core bond portfolios. So how can you position for a higher rate regime?
Bond portfolios have trouble with the curve
The yield curve (difference between the US 10-year and US 2-year yield) steepened last month to its widest level since 2018, surging to 128 from 96 basis points at the start of the month. This is all from movements in the US 10-year, as it rose by 34 basis points. Catalysts for these moves include dovish comments from the Federal Reserve2 and the US Treasury,3 a weak demand at the US Treasury auction,4 the House passing Biden’s stimulus bill,5 the FDA backing a third vaccine that will increase supply and potentially move herd immunity closer,6 potential technical selling from risk-parity funds as stock and bond correlations have risen,7 and stronger economic data, illustrated by the trend we have seen in ISM prices, as shown below.
Rates moving higher on the long end has flipped term premiums positive for the first time in over three years, as shown below. This trend is further evidence of the market pricing in higher future growth and inflation levels – and of investors requiring a higher yield as compensation on longer maturity bonds.
A higher rate regime, while beneficial for generating income, likely will continue to weigh on core bond portfolios, however. Duration remains extended and, while rates are higher today than at the start of the year, they offer too little support to offset any duration-induced price declines.
For example, a 50 basis points rise in rates would lead to a total return loss of 2.97%, based on the duration of the Bloomberg Barclays US Aggregate Bond Index (Agg) (6.3 years) and basic bond mathematics. Yet, not all of the Agg’s components would react the same way, as shown below. For example, the rate risk profile for Mortgages (3.57 years duration) is different than what other core bond sectors (US Treasuries, 6.88 years; US IG Corporate Bonds, 8.5 years) offer. And with a yield (1.78%) above core Aggregate bonds (1.53%) and US Treasuries (0.93%), plus lower volatility (2% versus 3% and 4%, respectively)8 , Mortgages may be a valuable overweight in the core.
Gearing up for the next at-bat
To the detriment of bond portfolios, and the rest of the sixty-forty portfolio, three catalysts, may keep rates rising:
In terms of inflation, expectations haven’t been this high versus actual levels since 2015, as measured by the difference between CPI and the US 2-year breakeven rates, however. The rise in breakevens is supported by the stimulus programs as well as the fact that the Fed is buying Treasury Inflation Protected Securities (TIPS) as part of its quantitative easing measures and now owns 20% of outstanding TIPS. Therefore, breakevens could be a bit inflated by the central bank’s demand.
Now, the differential between the two inflation measures, could mean two things for the future: 1) expectations get dialed back like they did in 2015 2) CPI begins to play catch up. The latter is more likely, given some of the low base effects, recent increases in oil prices, and stimulus effects discussed above.
A way to take a swing at higher rates
Core aggregate bonds (Agg) yield 1.53%,12 compared to two-year inflationary expectations of 2.56% 13– indicating a potentially negative real return from the coupon alone. Based on these dynamics, as well as those discussed earlier, there is one bond sector that may be able to increase yield as well as growth sensitivity: Senior Loans – one of the two segments with a positive return in 2021.
The case of senior loans can be made in three points:
Overall, the path ahead for rates over the next few months is likely going to be the same path birds take – migrating north as the weather turns warmer. And as the recovery forges on, the impact from rising rates on the standard sixty-forty allocation may upend what has worked over the past decade (growth stocks and long duration bonds). Investors’ ability to focus on rate sensitive stocks and growth sensitive bonds may, however, help mitigate the impact from this new higher rate and reflationary regime shift.

Equity securities may fluctuate in value in response to the activities of individual companies and general market and economic conditions.
Volatility management techniques may result in periods of loss and underperformance may limit the Fund's ability to participate in rising markets and may increase transaction costs.
A momentum style of investing emphasizes securities that have had higher recent price performance compared to other securities, which is subject to the risk that these securities may be more volatile and can turn quickly and cause significant variation from other types of investments.
Investments in small-sized companies may involve greater risks than in those of larger, better known companies.
Companies with large market capitalizations go in and out of favor based on market and economic conditions. Larger companies tend to be less volatile than companies with smaller market capitalizations. In exchange for this potentially lower risk, the value of the security may not rise as much as companies with smaller market capitalizations.
Value stocks can perform differently from the market as a whole. They can remain undervalued by the market for long periods of time.
Because of their narrow focus, sector funds tend to be more volatile.
