Global Bond Markets Hit Decades-High as Inflation Concerns Rise

Long-term borrowing costs have risen to their highest levels in decades across major economies, including the US, Japan, and Germany. This surge is attributed to renewed inflation worries and concerns over fiscal pressures facing these countries.

The 30-year bond yield in the US hit its highest since 2007, while Japan's 10-year borrowing costs reached a three-decade high just under 3%. In Europe, Germany's 10-year Bund yield touched its highest since 2011, and French yields were at their highest since 2009.

Kjersti Haugland, chief economist at DNB Carnegie, notes that bond markets are entering an era of uncertainty, with greater upside risks due to inflation and rate outlooks. This shift coincides with high government debt levels in several countries, particularly Japan, the US, France, and the UK.

Rising borrowing costs have a ripple effect on economies, setting the benchmark for borrowing costs for companies and other loans such as mortgages. Analysts point to competition for capital from AI hyperscalers, rising budget deficits, and concerns about clear communication from the Federal Reserve under new Chair Kevin Warsh.
