Long-term U.S. Treasury yields have climbed to their highest levels in years, raising concerns about the outlook for interest rates and fixed income portfolio performance for many investors. While rising inflation is often cited as a primary culprit for higher rates, the recent increase in yields reflects a broader mix of economic and market factors, as we addressed in our recent commentary.
The ballooning national debt and structurally higher deficits, growing AI investment-related debt issuance, and the evolution of Federal Reserve communication and policy execution are among the factors influencing the overall rate environment. Not only have expectations shifted from rate cuts early this year to a rate hike cycle that’s now underway, the Federal Reserve’s chairman, Kevin Warsh, has emphasized greater reliance on incoming economic data, flexibility in policy execution, and less explicit forward guidance. Investors who grew accustomed to more prescriptive Fed communication in the post-2008 era are grappling with this new opacity, and significant questions about the Fed’s reaction function and the practical implications of those changes. Meanwhile, long-term inflation expectations have remained relatively well anchored, suggesting investors continue to believe that inflation will gradually move closer to the Federal Reserve’s 2% inflation target over time.
What could drive rates from here?
Beyond those factors, long-term rates should also be considered in the context of nominal economic growth. Treasury yields have historically moved in relation to nominal GDP growth (the sum of real GDP growth and inflation), which is running considerably higher than was the case from 2009 through 2020. Thus, the current environment increasingly appears to reflect a normalization from the unusually slow growth, low inflation, and exceptionally accommodative monetary policy that followed the Global Financial Crisis. Energy-related inflation tied to the ongoing Iran conflict, evolving global trade dynamics, resilient consumer spending, constructive labor conditions, and high structural fiscal deficits all support the case for rates that could stay elevated, compared to the prior decade, or even move higher.
At the same time, several forces could keep yields rangebound. Inflation has fallen significantly from its peak despite a series of major supply-side shocks in recent years, including the severe economic disruption from the COVID-19 pandemic, the Russia-Ukraine conflict, tariffs, and the recent surge in energy prices. Wage growth has moderated, labor market dynamics appear less inflationary than headline unemployment figures suggest, and long-term inflation expectations have remained well anchored.
The AI story has both near-term inflationary and potentially longer-term disinflationary elements as well. While today’s infrastructure buildout is contributing to elevated borrowing needs and new debt issuance contributing to higher rates, successful adoption could boost productivity, increase output, and lower costs across the economy as new technology tools are implemented.
Finally, higher interest rates may become their own counterweight. Elevated interest rates create tighter financial conditions, reduce borrowers’ appetite, and could eventually feed into a slower pace of economic growth over time. Beyond Fed rate hikes, upward pressure on long-term rates directly tightens financial conditions, a reality that appears to be a central component of Fed Chair Warsh’s views on policy execution going forward. It also feeds directly into his stated desire to reduce or eliminate forward guidance and rely less on bond purchases and Fed balance sheet expansion to influence rates further out the curve.
What does this mean for investors?
The recent rise in yields has been frustrating for bond investors, but it’s important to separate short-term market volatility and performance from long-term return expectations.
The last time the 10-year Treasury touched 5% was in the fall of 2023, at a time when inflation and surging interest rates heavily influenced market sentiment as they do today. Yields, however, declined by more than 1.0% over subsequent months, in turn helping to drive a strong bond market rally into year-end that lifted the Bloomberg Aggregate Index by more than 8% in the final two months of the year. That recent experience serves as a poignant reminder that short-term moves in interest rates are notoriously difficult to predict and can cut both ways to either the detriment or benefit of bond pricing.
More importantly, although rate volatility can be a key driver of bond performance over shorter periods, long-term fixed income returns are highly correlated with starting yields, with that predictive value increasing as one’s investment holding period lengthens. Today’s environment offers investors something that was largely absent for much of the post-Global Financial Crisis period: meaningfully positive real yields, which is the additional yield investors receive over the current inflation rate. In fact, real yields are near their highest level in nearly two decades, contributing to a substantially improved fixed income return outlook. Importantly, investors are also being compensated for extending beyond cash, as the steeper yield curve adds to the term premium, allowing longer-term bonds to offer yields in excess of cash, supporting portfolio objectives, and contributing more meaningfully to total portfolio returns over an extended investment horizon.
Despite the recent uptick in interest rates across the curve, the yield buffer in fixed income has allowed fixed income investors to limit downside while collecting their coupon payments. More importantly, investors who step back from the volatility of a single calendar year can see a very different picture. Over the past three years, high-quality fixed income has produced mid-single-digit annualized returns, while many actively managed strategies have exceeded those results.
The key takeaway is that today’s bond market continues to present a meaningfully different opportunity set than investors have experienced for much of the past 20 years. Fiscal concerns, increased debt issuance tied to massive AI investment, the evolution of Fed communication and policy execution, and a resilient economy are all contributing to rising yields and greater rate volatility. Conversely, long-term inflation expectations remain anchored, other disinflationary forces are present or likely to emerge, and current yields provide an attractive starting point for future bond returns.
The commencement of a Fed tightening cycle and its broad economic and market impact will likely continue to drive headlines in the coming months. Still, investors should be cautious about making significant allocation changes based on short-term fluctuations in interest rates. The historically attractive income available in today’s bond market continues to support a favorable long-term outlook for high-quality fixed income — one that effectively makes a stronger case, not a weaker one, for bond investors over a multiyear time horizon.
