Treasury buybacks failed to calm long bonds as markets turned to U.S. CPI
Global markets saw an unusual mix of signals on Sept. 10. The U.S. Treasury increased its long-dated bond buyback size to $6 billion from the previously announced $4 billion, yet the 10-year Treasury yield still climbed to 4.85%, its highest level since November 2023, while the 30-year yield moved above 5.3%. At the same time, U.S. August producer price data came in with a 0.4% month-on-month gain and 5.4% year-on-year growth, while July figures were revised higher, reinforcing expectations that inflation pressure has been rebuilding since mid-summer. Gold reacted sharply. Prices fell after the PPI release, touching $4,324.23 intraday and ending the New York session down 1.91% at $4,314.82, though the broader move was described as a V-shaped pattern. Outside the U.S., the European Central Bank raised its three key rates by 25 basis points, taking the deposit facility rate to 2.50%, and markets were also pricing about a 97% chance that the Bank of Japan would raise rates by 25 basis points to 1.25% next week. Against that backdrop, investors are now focused on the U.S. August CPI report due at 20:30 Beijing time. The article frames the release as the next major test for rate expectations, long-end Treasury yields, and the current gold narrative, which it says is increasingly tied not only to interest rates but also to concerns over U.S. fiscal credibility.
