Global bond markets experienced a significant selloff, pushing US 30-year Treasury yields to their highest level since 2004. Yields on the longest-dated bonds climbed to 5.44%, driven by inflation fears and rising oil prices. European yields also increased, while Japanese government debt reached levels last seen in 1996 following a market reopening. The worldwide average yield neared 4%, the highest point since 2007, reflecting the end of the low-yield era.

The surge in borrowing costs places pressure on the US administration ahead of the midterm elections, with dissatisfaction mounting over mortgage rates and living costs. The rise in yields undermines Treasury efforts to lower long-term costs, despite expanding buyback programs. Market strategists indicate that forces are currently behaving rationally amid strong economic data and energy-driven inflation.

Analysts at major financial institutions project further yield increases, forecasting potential Federal Reserve tightening. The selloff has impacted global markets, with German 10-year and Japanese 10-year yields hitting multi-year highs. Government bonds have suffered losses this year, and volatility remains elevated, prompting investor caution despite attractive higher yields.
