US Treasury Yields Surge to Multi-Decade Peaks, Pressuring Global Markets

On October 1, the benchmark 10-year U.S. Treasury yield climbed above 5.3%, a level not seen since April 2002. LSEG recorded 5.3338%; other trackers showed intraday highs of 5.342% and 5.327%. The 30-year Treasury rose to 5.6702%, its highest since July 2002, lifting all three major U.S. equity indexes before a late-day reversal.

The surge follows months of rising inflation expectations, persistent fiscal deficits, and strong demand for AI-related projects. Higher energy prices and Middle-East tensions have added to inflation pressure, while Treasury issuance has expanded to fund deficits. Foreign holders such as China and Japan have trimmed U.S. bond positions, tightening demand. Robust U.S. manufacturing and a resilient economy have led investors to expect the Federal Reserve may keep policy rates elevated for an extended period.

Higher long-term yields raise borrowing costs for mortgages, auto loans and credit-card debt, directly affecting households. Corporations—especially capital-intensive sectors such as construction, data-center expansion and airlines—face steeper financing costs. Governments worldwide encounter tighter fiscal space as debt-service obligations climb, limiting large-scale stimulus. Emerging-market bond spreads remain low, but the risk of capital outflows rises if U.S. yields stay elevated.

Sources differ on the precise 10-year peak: Reuters-based commentary cites a retreat to around 5.26% after early gains, while CNBC reports 5.3338% and Briefs records 5.327%.
