Rising Treasury yields: Why buybacks won’t fix a term premium problem

Investors are becoming increasingly concerned about the risks of owning long-term government bonds.

What happened?

The U.S. Treasury market has sold off sharply in recent weeks, with 30-year Treasury yields briefly reaching their highest level since 2004. The move culminated last week with Treasury Secretary Scott Bessent announcing an expansion of Treasury buyback operations aimed at improving long-end market liquidity. While the announcement initially triggered a rally in government bonds, the effect quickly faded, and yields have since retraced much of the initial decline.

The broader market reaction has been notable. Gold prices have rallied, the U.S. dollar has weakened, and equities have come under pressure as investors increasingly question whether persistent fiscal deficits and rising debt issuance require structurally higher real yields to attract capital. The S&P 500 has fallen roughly 2% from recent highs as elevated discount rates challenge stretched valuations.

Why are yields rising?

The sell-off initially gained momentum after the July FOMC meeting, as investors became less certain about Federal Reserve Chair Kevin Warsh’s reaction function and commitment to price stability. Markets responded by pricing a higher terminal policy rate, pushing yields higher across the curve.

However, the story has since evolved. Treasury yields continued rising even as payroll growth, retail sales, housing activity, and inflation softened. Normally, such data would lead yields lower. Instead, investors have demanded greater compensation for holding long-duration assets.

This suggests that what began as a monetary-policy story has increasingly become a term-premium story. This distinction is important. If rising yields were primarily an inflation story, additional policy tightening or more hawkish Fed communication could potentially reverse the move. Instead, investors are becoming increasingly concerned about the risks of owning long-term government bonds in an environment characterized by greater inflation volatility, geopolitical uncertainty, persistent fiscal deficits, and rising public debt.

Indeed, before the pandemic, investors could reasonably assume stable inflation, low policy rates, and limited fiscal expansion. Today, those assumptions no longer hold. Frequent geopolitical disruptions are threatening supply chains and energy markets, creating more volatile inflation outcomes. Governments face growing spending pressures from aging populations, infrastructure investment, and defence expenditure, while deficits remain large across much of the developed world.

The result is sustained debt issuance with little evidence of a credible plan to stabilize public finances. At the same time, AI-related investment has increased private-sector demand for capital. As governments and companies compete for a limited supply of capital, investors are demanding higher returns to provide financing.

The recent rise in yields, therefore, reflects more than a U.S. Treasury story. It represents a broader repricing of long-term capital and duration risk as debt issuance expands and competition for capital intensifies across the developed world.

Why Treasury buybacks are unlikely to solve the problem

The Treasury’s expanded buyback program may improve market functioning, but it does little to address the fundamental drivers of higher yields.

Buybacks do not reduce borrowing requirements. To repurchase long-dated securities, the Treasury must issue additional short-dated debt. The operation changes the composition of outstanding debt but not the amount that ultimately needs to be financed.

Therefore, the announcement should be viewed as a liquidity measure rather than a solution to elevated borrowing costs. While it may alleviate temporary market dislocations, it is unlikely to reverse the structural forces pushing term premiums higher. Indeed, if investors view buybacks as a government step toward artificially keeping borrowing costs low or some sort of debt monetization, risk premiums could rise further.

What does this mean for the Fed?

The Treasury’s intervention has ambiguous implications for monetary policy. In recent months, Chair Warsh has largely welcomed higher long-term yields as a mechanism for tightening financial conditions. By contrast, the Treasury’s buyback expansion signals growing concern about rising borrowing costs.

If buybacks successfully reduce term premiums and ease financial conditions, the Fed may need to rely more heavily on policy-rate increases to achieve its inflation objectives. Alternatively, investors may interpret the move as evidence that policymakers are becoming less comfortable with higher yields, reducing expectations for further tightening.

Either way, the announcement has not only introduced a new element of uncertainty into the policy outlook but also highlighted a growing tension between the Treasury’s desire to contain borrowing costs and the Fed’s objective of maintaining sufficiently restrictive financial conditions to achieve price stability.

What could reverse the move?

A sustained decline in long-term yields would likely require one of three developments:

1. A meaningful deterioration in economic activity that forces markets to reassess growth and real-rate expectations.

2. A credible fiscal adjustment that reduces concerns about future debt supply and fiscal sustainability. Given current political constraints, this appears unlikely in the near term.

3. A restoration of monetary-policy credibility through greater clarity around the Fed’s reaction function. However, given the growing importance of term-premium dynamics, improved communication alone may not be sufficient.

Investor implications

The key message for investors is that higher yields increasingly reflect structural, rather than cyclical, forces. Treasury interventions may slow the adjustment, but they do not materially alter the underlying supply-demand imbalance in long-duration assets.

The implications for equities are important. Higher bond yields reduce the present value of future earnings and place downward pressure on valuations, particularly in long-duration growth sectors. They may also threaten one of the market’s key supports: the wave of AI-related capital expenditure. While these AI companies currently appear yield-agnostic, if rising financing costs begin to constrain investment spending, an important source of earnings optimism could weaken.

Overall, Treasury yields appear to have evolved from a monetary-policy story into a term-premium story. Persistent fiscal deficits, rising debt issuance, greater macroeconomic uncertainty, and stronger competition for global capital all point to structurally higher term premiums. Treasury buybacks may improve market liquidity, but they are unlikely to reverse the broader repricing of duration risk. Until concerns around fiscal sustainability and debt supply ease, investors should expect long-term yields to remain elevated and volatility across asset classes to persist.
