The Story

Global government bond yields are at or near multi-decade peaks on Tuesday due to heightened worries about inflation and rising interest rates.

Japan's 10-year bond yield hit 3% for the first time since 1996, marking a 30-year high. The U.S. 10-year Treasury note yield rose to about 4.79% on Tuesday, its highest level since January 2025. The U.S. 30-year Treasury bond yield was above 5.2% on Tuesday, having risen to its highest since 2007 earlier in August.

Germany's 10-year Bund climbed above 3.36% on Tuesday, a 15-year high. The French 10-year OAT yield rose to its highest level since November 2008, and the Dutch 10-year government bond yield increased to 3.43%, its highest since May 2011. The immediate cause for the surge in yields includes renewed tensions in the Middle East, specifically U.S. forces launching strikes against Iran and a tanker being struck off the coast of Oman.

These tensions pushed oil prices higher, with Brent crude advancing more than 2% to above $92 per barrel on Tuesday. Federal Reserve Chairman Kevin Warsh indicated discomfort with the current rate of inflation, which investors interpreted as a signal for likely interest rate increases. Ulrike Hoffmann-Burchardi, UBS chief investment officer, cited no clear path to reopening the Strait after six months of war, elevated inflation worries, Fed policy uncertainty, fiscal concerns, and rising AI-related debt issuance as contributing factors.

The U.S. debt pile recently crossed $40 trillion. Eurozone inflation reached 3.3% in August, up from 2.9% in July, with energy prices 14.3% higher year-on-year. Higher borrowing costs are expected for consumers, impacting mortgages, auto loans, and credit card debt.
