Japan's Bond Market Selloff May Drive Treasury Rates Significantly Higher

Japanese Government Bond yields are surging, narrowing the U.S.-Japan rate spread to decade lows and pressuring global interest rates higher. Despite interventions, the Japanese yen continues to weaken, reflecting investor doubts about Bank of Japan policy credibility and Japan's fiscal path. Rising Japanese rates are catalyzing a global repricing, with long-term yields in Korea, France, the UK, and Germany also reaching multi-year highs. Technical patterns suggest U.S. 30-year yields could reach 6% if current trends persist, driven by bear steepening and global rate contagion.

Rates are rising in the U.S. and around the world, with the biggest moves coming from Japan. The 30-year Japanese Government Bond yield has risen to 4.14%, and since 2000, outside of May 2026, it has never been higher.
