U.S. Treasuries Face Renewed Inflation Pressure

The global bond selloff intensified as investors reassessed the inflation outlook following renewed military tensions around the Strait of Hormuz. The U.S. 10-year Treasury yield rose 3 basis points to approximately 4.788%, reaching its highest level in 20 months. The move reflects more than geopolitical risk: investors are increasingly concerned that higher energy prices could make inflation more persistent and reduce the room for central banks to ease policy.

U.S. Treasury Secretary Scott Bessent defended the resilience of the American bond market, describing it as the world’s “best performing market” and pointing to the country’s AA+ sovereign rating. Yet Standard Chartered’s Steve Englander offered a more cautious interpretation, arguing that being the best-performing market does not necessarily mean the market is performing well. The distinction highlights growing concern about fiscal deficits alongside inflation.

Japan and Britain Become Major Pressure Points

Japan’s bond market experienced one of the session’s most significant moves. The 10-year Japanese government bond yield climbed more than 6 basis points to 3%, its highest level since 1996, while the two-year yield reached 1.81%, a 31-year high. Rising yields could further influence expectations for Japanese monetary policy and place additional pressure on the country’s already sensitive currency and government financing dynamics.

U.K. government bonds also came under heavy selling. The 10-year Gilt yield rose more than 9 basis points to 5.2341%, its highest level since June 2008, while the 30-year yield reached 5.8856%, a level not seen since March 1998. The magnitude of the move demonstrates how global investors are increasingly demanding compensation for inflation and fiscal risks across developed markets.

Europe and Energy Add to the Global Repricing

Germany’s 10-year Bund yield increased more than 3 basis points to 3.3546%, reaching a new 52-week high, while the two-year Bund yield climbed to 2.9496%, its highest level since July 2024. France’s two-year borrowing costs also reached their highest level since April 2024.

Energy markets are central to the repricing. Brent crude rose about 2.2% to $92.38 a barrel, while West Texas Intermediate gained 2.61% to $88.05 as renewed U.S.-Iran strikes heightened supply concerns. Persistent energy inflation could make it more difficult for policymakers to prioritize economic growth over price stability.

What Investors Should Watch Next

The critical question for markets is whether the bond selloff remains a temporary geopolitical reaction or develops into a broader reassessment of inflation and sovereign fiscal risk. Sustained oil prices above $90 could reinforce upward pressure on yields, increasing financing costs for governments, businesses and households. Investors will therefore be watching energy markets, central-bank signals and fiscal developments closely. If yields continue rising across major economies simultaneously, the consequences could extend well beyond fixed income, creating a more challenging environment for global equities and other rate-sensitive assets.
