Why Bonds May Keep Beating Stocks

Consider three reasons to continue favoring fixed income as bonds may keep outperforming.

Key Takeaways

  • Current bond yields are strongly superior to pricing for the S&P 500 Index, with equity risk premiums at 20-year lows.
  • A favorable policy environment, including eventual Fed rate cuts and bank deregulation, may support continued strength in fixed income.
  • Despite fears to the contrary, bonds with short and intermediate durations still offer diversification potential in stock-bond portfolios.
  • Consider maintaining above-normal exposure to investment-grade and municipal bonds with short to neutral durations, while adding international equities, commodities and energy infrastructure.

While many investors focus on the U.S. stock market’s resilience, Morgan Stanley’s Global Investment Committee believes the real story is that, year to date, bonds are outperforming stocks.

 

Indeed, while the S&P 500 was up 1.5% year-to-date as of Friday, U.S. Treasuries, investment-grade bonds and high-yield bonds posted superior total returns of 2.8%, 2.9% and 3.4%, respectively. (“Total returns” for bonds encompass both interest payments and any capital gains or losses.)

 

The bond market’s outperformance is surprising – and not just because historically, stocks have generally provided higher returns, with higher volatility, over the long term. The fixed income market has also been resilient in the face of significant challenges lately, ranging from investors’ disappointment about the Federal Reserve’s pause in interest rate cuts, to concerns about inflation and the swelling U.S. debt load, both of which risk higher yields and lower bond prices. And importantly, bonds look poised to continue outperforming. 

 

Here are three reasons we favor fixed income in 2025, particularly in short and intermediate durations.

Hold On Loosely

Did you know bonds are outperforming stocks so far this year? Here’s why we think fixed income’s relative strength could continue.

  1. 1
    Superior yields

    First, bonds are currently priced to provide positive after-inflation returns, with yields averaging at least 4% on U.S. Treasuries, about 5% on investment-grade corporates and more than 7% on high-yield bonds. These yields are strongly superior to how the S&P 500 index is priced. “Equity risk premiums” (i.e., the additional returns investors may expect for investing in stocks instead of bonds) remain at 20-year lows, hovering around zero – a level that is hard to believe given mounting risks from domestic policy uncertainty and geopolitical tensions, which now include conflict between Iran and the U.S. and Israel.

  2. 2
    A favorable policy backdrop

    Changing monetary policy and deregulation could also benefit bonds with short and intermediate maturities.

     

    For one, eventual Fed rate cuts may drive yields lower and thus support higher bond prices. That said, the yield curve currently is not “aggressively priced,” meaning the market’s expectations for future rate changes appear relatively moderate, with any rate declines appearing more likely in shorter-duration bonds.

     

    On the deregulation front, U.S. federal regulators may loosen bank capital requirements. This could allow banks to increase their Treasury holdings, potentially supporting bond prices, at a time when the U.S. government is likely to issue more Treasury securities to support government spending when Congress likely raises the debt ceiling this summer. More than one-third of this new government debt is expected in shorter-term maturities.

     

    Also, new federal legislation to establish clearer rules around “stablecoins” could spur activity for these popular cryptocurrencies. Since stablecoins are frequently backed by U.S. hard currency collateral, this activity could, in turn, drive demand for short-duration Treasuries that are considered cash-equivalent securities. 

  3. 3
    Diversification potential

    Finally, investor concerns about bonds’ loss of diversification potential may be overblown. While equity-return correlations are strongly positive – and rising – with 30-year bonds, our analysis shows that two-year bonds remain strongly negatively correlated to equities – meaning they typically rise when stocks fall, and vice versa, potentially offsetting losses in a portfolio.

     

    The takeaway: Bonds’ potential diversification benefits are only a constraint for longer-duration bonds. Maintaining above-normal exposure to shorter-duration bonds, as we recommend, should still provide volatility buffers.

How to Invest

Overall, now is not the time to abandon your fixed income allocations.

 

Consider maintaining additional exposure to investment-grade and municipal bonds with short to neutral durations, and position your portfolio for a backdrop of average 5%-10% U.S. equity returns, in an environment of more volatility, higher real rates and a weaker U.S. dollar.

 

Also consider adding diversifying positions in international equities, commodities, energy infrastructure and hedge funds.
