Global Government Bond Yields Surge to Multi-Decade Highs Amid Inflation and Fiscal Concerns

Long-term sovereign borrowing costs across major developed economies have reached multi-decade highs, signaling a significant shift in the global fixed-income landscape. This surge is attributed to persistent inflation pressures, growing fiscal deficits, and evolving global liquidity conditions. Notably, U.S. 30-year Treasury yields have touched levels not seen since 2007, while U.K. 30-year gilts have climbed to peaks last observed in 1998. Japan's 30-year government bond yields are also nearing historical highs as the Bank of Japan navigates its exit from yield curve control. The U.S. Treasury recently more than doubled the size of its scheduled bond buyback operations.
