Global Sovereign Debt Yields Surge to Multi-Decade Highs, Stress Intensifies

Sovereign debt markets are experiencing heightened volatility as yields in advanced economies reach multi-decade highs, with Japan and the UK seeing long-term funding costs at record levels and the US 10-year Treasury yield hitting its highest since January 2025. This signals persistent fiscal stress and market repricing of government debt, which could have broad implications for global borrowing costs and risk assets. The trend is ongoing, with no immediate catalyst identified, but the escalation suggests a structural shift in market sentiment.
