U.S. Treasury yields slide after CPI-driven spike as inflation hits 3.7%
U.S. Treasury yields drifted lower following a volatile reaction to a hotter-than-expected Consumer Price Index report. Annual inflation accelerated to 3.7% in September, reviving debates over potential Federal Reserve tightening.
⚡ Key numbers:
- U.S. annual CPI inflation rose to 3.7% in September.

September CPI inflation tops expectations
Consumer prices in the United States rose 0.6% on a monthly basis in September, pushing the annual inflation rate up to 3.7% from 3.4% in August. The figures outpaced economists' forecasts as reported by major market platforms.
Higher gasoline, diesel, and food costs drove headline inflation higher, while core CPI, excluding volatile food and energy items, accelerated to 2.6% from 2.4% in the previous month.
Fed rate hike expectations and market repricing
The sticky inflation reading triggered an immediate repricing in money markets. Traders briefly raised the probability of an interest rate increase at the upcoming Federal Reserve meeting significantly higher.
While futures markets subsequently moderated those aggressive bets, the data intensified discussions on whether central bankers will need to maintain a restrictive stance for longer.
