U.S. Treasury Yields Hit Two-Decade Highs Amid Rising Inflation And Rate Fears

Fed funds futures put the odds of a rate increase the following month at 71%, up from about 53% before stronger business-activity data was released.
The U.S. national debt was roughly $40.1 trillion, after crossing the $40 trillion mark in August, adding to investor concerns about public borrowing.
The Federal Reserve’s projections showed that 16 of 18 committee participants expected at least one more rate increase before the end of 2026.
The Treasury bought back $4.078 billion in 20- to 30-year bonds, while investors offered $10.468 billion in bonds for the operation; the Treasury had said it would buy back up to $6 billion.
U.S. Treasury yields surged to their highest levels in roughly two decades on September 24, with the 30-year yield touching 5.45% and the 10-year near 5.1%, according to Bloomberg. The sharp selloff was driven by rising oil prices from Middle East tensions, persistent inflation concerns, and growing expectations that the Federal Reserve will raise interest rates again soon.
Fed funds futures now show a 71% probability of a rate hike in the coming month, up sharply from 53% before recent strong business data. Meanwhile, the U.S. national debt has climbed to roughly $40.1 trillion, amplifying investor concerns about heavy government borrowing and debt issuance, according to LiveMint.
Oil prices jumped about 3% to a one-week high after rising concerns about supply disruptions in the Strait of Hormuz, according to DevDiscourse. The waterway handles roughly one-fifth of global oil shipments, and any disruption sends crude toward $95–$97 per barrel. This energy shock has reignited inflation fears across financial markets.
Powerful business-activity reports and solid labor data—with unemployment claims falling to 197,000—have pushed traders to sharply raise their bets on further Federal Reserve rate increases. Futures markets now price a 71% chance of a hike next month, compared with 53% just days earlier, according to market data. The Fed's own projections show 16 of 18 committee members expect at least one more rate increase before the end of 2026.
The U.S. Treasury conducted a buyback operation to support liquidity in long-dated bonds, purchasing just $4.078 billion in 20- to 30-year debt out of a $6 billion cap. Investors offered $10.468 billion in bonds for the operation, far exceeding what Treasury could absorb, according to LiveMint. The mismatch signals that buyback programs have offered little market relief.
Mounting fiscal pressures are behind the selloff. The U.S. debt has ballooned by $3.8 trillion since mid-2025 to hit $40.1 trillion, with debt-to-GDP now exceeding 100%. Gennadiy Goldberg, head of U.S. rates strategy at TD Securities, blamed "a combination of rising Fed hike expectations, higher growth expectations, higher oil prices, fiscal concerns, and hyperscaler issuance" for the sharp rate spike.
The selloff extended far beyond U.S. shores. Japanese long-term yields hit multi-decade highs, while the gap between French and German 10-year government bond yields widened, signaling strain across Europe. The stock market felt the pain too: the Dow Jones Industrial Average fell 0.31%, and broader global indexes stumbled as higher borrowing costs weighed on equities, according to Bloomberg.
