US government bond yields surged to fresh multiyear highs, with the 30-year bond's yield reaching levels not seen since 2007. The two-year note's yield also surpassed 4.5% for the first time since 2024. These increases, ranging from six to eight basis points across various maturities, were primarily attributed to an extended rally in oil prices, which fueled traders' expectations for an imminent Federal Reserve interest rate hike.

Traders significantly boosted their forecasts for a Fed rate hike next week, with expectations rising to approximately 70%. They also fully priced in a rate increase by October, a shift from previous predictions that anticipated a move by December. This increased conviction in a near-term rate hike reflects growing concerns among investors about inflationary pressures, exacerbated by the rising cost of oil.

The climb in yields follows a period of heightened market sensitivity to economic indicators and central bank policy. The market's reaction suggests that investors are bracing for a more aggressive stance from the Federal Reserve to combat inflation, even as longer-term yields like the 30-year bond show strong demand in auctions, indicating some investor appetite for higher-yielding, longer-duration debt despite the overall rise in rates.
