Global bond markets are signaling a September rate hike derby, with yields across major economies surging to multi-year peaks as traders price aggressive tightening cycles from the Federal Reserve, European Central Bank, Bank of Japan and others.
The U.S. 10-year Treasury yield has climbed to 4.77%, its highest since January 2025, while Japan’s 10-year yield touched 3% for the first time since 1996. Australian government bond yields have reached levels not seen since 2011, and Bloomberg’s global government bond gauge has risen to 3.72%, the highest since 2008. The steepening yield curve reflects growing concerns over fiscal pressures, sticky inflation and robust debt issuance from governments, corporations and AI-driven hyperscalers.
The Fed’s rate hike probability has jumped to roughly 65% for September, up sharply from prior levels. Two-year SOFR remains above 4.20%, with about 16 basis points of tightening priced for September and 37 basis points through year-end. However, the dollar has struggled despite higher front-end rates, with G10 currencies gaining against it on Monday amid consolidation in Asian trading. The back-end of the curve may be tempering dollar strength, as rising long Treasury yields raise questions about potential fiscal interventions.
Friday’s U.S. nonfarm payrolls report will serve as a key marker for Fed policy expectations. A gain near the 65,000 estimate would likely keep the September hike firmly in play, though the dollar’s upside may be limited given the rapid repricing of rate expectations.
Across the Atlantic, the ECB is nearly fully priced for a September hike, with German inflation ticking higher to 2.9% in August and eurozone headline inflation expected around 3.3%. The focus now shifts to whether the ECB frames the move as an insurance hike or the start of a more restrictive cycle. With so much already reflected in prices, the euro-dollar exchange rate is increasingly driven by U.S. data, with 1.1600 looking vulnerable if U.S. figures support further Fed tightening. The 1.1500 level could come into view in early September.
Japan presents a more nuanced scenario, with overnight swaps implying roughly a 90% probability of a Bank of Japan hike at its September 17-18 meeting—more than double the odds a month ago. The shift follows a sharp rise in Japanese yields and signals from U.S. officials, including Scott Bessent, who has suggested tighter Japanese monetary policy could ease pressure on the yen. However, the currency remains near 160 per dollar, underscoring the challenge of aligning policy expectations with FX outcomes.
The Reserve Bank of Australia is another live contender, with markets attaching roughly a 54% probability to a September 29 increase. Meanwhile, the Reserve Bank of New Zealand is expected to raise rates by 25 basis points to 2.75% on Wednesday, with nearly 100 basis points of additional tightening priced through June 2027. The kiwi’s reaction may hinge less on the hike itself and more on whether the RBNZ validates the aggressive rate path already reflected in markets.
For FX traders, the September policy derby may hinge less on identifying the central bank most likely to hike and more on spotting where market expectations are misaligned with actual policy paths.
