Japan’s borrowing costs hit 30-year high: what does it mean for global markets?
Affected assets and topics
Why it matters
Japan's long-term government bond yields reached a 30-year high, driven by weeks of scrutiny over fiscal and monetary policies and recent currency market intervention by Japan and the U.S. This development may signal tightening financial conditions in Japan, with potential spillover effects on global bond markets and risk assets.

Expected market reaction
The rise in Japan's borrowing costs could increase global bond yields, particularly in sovereign debt markets, as investors reassess risk premia. Japanese financial institutions and exporters with significant yen-denominated liabilities may face higher funding costs, while global investors holding Japanese government bonds (JGBs) could see mark-to-market losses.
