• Kansas City Fed President Jeff Schmid said U.S. debt 'seems extreme,' highlighting fiscal risks that could keep long-term interest rates higher.
  • The warning comes as the federal deficit is projected to hit $1.9 trillion in 2026, with net interest costs exceeding $1 trillion.
  • Markets are watching Treasury auctions and term premiums for signs of strain, while the Fed remains focused on returning inflation to target.

Kansas City Fed President Jeff Schmid doesn't typically grab headlines, but his recent comment that U.S. debt "seems extreme" is resonating on Wall Street and in Washington. The remark, made during a speaking engagement earlier this week, underscores growing unease about the trajectory of federal borrowing and its potential to complicate the Federal Reserve's job.

Schmid, who represents the Tenth Federal Reserve District on the FOMC, is not a near-term voting member in 2026. But his views carry weight as markets parse every signal on how fiscal policy might shape monetary policy. "Persistent deficits and heavy Treasury issuance can keep longer-term interest rates structurally higher," Schmid said, adding that this dynamic could make it harder for the Fed to bring inflation back to its 2% target.

The numbers are stark. The Congressional Budget Office projects a fiscal year 2026 deficit of $1.9 trillion, or 5.8% of GDP, rising to $3.1 trillion, or 6.7% of GDP, by 2036. Net interest costs alone are expected to top $1 trillion in 2026 and more than double to $2.1 trillion in 2036, at which point they would consume nearly one-fifth of federal spending. Debt held by the public is on track to reach 120% of GDP by 2036—surpassing the post-World War II record of 106% set in 1946.

The concern is a feedback loop: high deficits require more Treasury issuance, which may force the government to offer higher yields to attract buyers. Those higher yields increase federal interest expense, widening future deficits. "The math is not sustainable," said one fixed-income strategist who requested anonymity to speak candidly. "At some point, the bond market will demand a bigger premium for fiscal risk."

Treasury has been trying to manage the supply. In August, it announced an increase in the maximum size of its nominal long-end buyback operations from $2 billion to at least $4 billion per operation, effective September 9 through the remainder of the quarter. Schmid noted that such buybacks "do not make monetary-policy implementation easier or harder," but they may support market functioning at the margin.

Still, buybacks don't reduce the underlying borrowing requirement. And with the Fed holding rates steady in recent months, the focus is shifting to whether fiscal pressures could push long-term yields higher even without further policy tightening. CBO projects the 10-year Treasury rate at 4.1% in 2026 and 4.4% by 2031, but some analysts see upside risks.

"If investors start demanding compensation for inflation or fiscal risk, the term premium could rise significantly," said Priya Misra, a rates strategist at a major bank, who spoke on a conference panel last week. "That would tighten financial conditions for households and businesses, potentially forcing the Fed's hand."

The political context is equally fraught. Deficit reduction generally requires tax increases, spending cuts, or both—options that are politically difficult. The 2025 reconciliation act, higher tariffs, and lower immigration have all been factored into CBO's baseline, but the debate over urgency and remedy continues.

For now, markets are focused on three indicators: inflation and labor-market data, Treasury auction demand and term premiums, and congressional budget decisions. Any of these could shift the outlook.

A spokesperson for the Kansas City Fed declined to comment beyond Schmid's public remarks. The Treasury Department did not respond to a request for comment.
