Yields on US government bonds have reached new multiyear highs, driven by a continued surge in oil prices. This has prompted traders to significantly increase their expectations for a Federal Reserve interest rate hike, with some predicting a move as soon as next week. Treasury yields across all maturities, from short to long-term, rose by six to eight basis points. The yield on the 30-year bond is now at levels not seen since 2007, while the two-year note's yield has surpassed 4.5% for the first time since 2024. These movements reflect growing market conviction that the Federal Reserve will act to counter inflationary pressures.

Traders are now pricing in approximately a 70% chance of a Fed rate hike occurring next week. Furthermore, a rate increase by October is now fully anticipated by the market, a shift from previous expectations that had pointed to December. This accelerated timeline for monetary tightening is a direct response to the persistent rise in oil prices, which fuels concerns about inflation and the need for the Fed to intervene to stabilize prices.

The increase in bond yields follows a period of heightened activity in the Treasury market. On September 9, benchmark 10-year Treasury yields reached their highest levels since 2023. This occurred after the Treasury Department announced an enlarged buyback of longer-dated bonds, which initially disappointed some investors expecting a larger intervention. Despite this, demand remained strong for a $39 billion sale of 10-year notes, with the highest winning yield recorded at 4.834%, marking the highest 10-year auction yield since August 2007.
