Japan’s benchmark 10-year government bond yield rose to 2.945% on Tuesday, advancing for a seventh consecutive session and approaching levels last seen in September 1996. The yield, which has more than tripled in two years, reflects mounting concerns over inflation and fiscal sustainability as Japan’s debt exceeds 200% of GDP.
Short-term yields also surged, with the five-year rate setting a record high and the two-year yield reaching a 31-year peak. The effective interest rate in Japan currently stands at about 1.07%, with projections indicating it could rise to 1.32% if the Bank of Japan (BOJ) implements a 1.5% rate hike by fiscal 2027. Analysts note that bond yields across major markets, including the United States, Germany, and France, have also climbed to multi-year highs in recent sessions.
Market participants attribute the upward pressure on yields to a combination of domestic and global factors. Prime Minister Sanae Takaichi, who took office in October, has pursued an investment-led growth strategy targeting strategic industries alongside planned tax cuts, raising concerns about Japan’s fiscal trajectory. A recent 10-year JGB auction recorded the weakest demand in a year, underscoring investor unease.
The Japanese yen remains near a four-decade low, while global inflation risks are exacerbated by geopolitical tensions in the Middle East, including a U.S.–Iran conflict and elevated oil prices. Shoki Omori, chief fixed income strategist for Japan at Deutsche Bank, described the rise in yields as "normalisation with a warning label," adding that once the BOJ signals its terminal rate, 3% could become a key level where dip-buying outweighs momentum selling.
Tsuyoshi Ueno, chief economist at NLI Research Institute, warned that breaking above 3% is symbolic and could intensify yen-selling pressure if attention shifts to underlying inflation and fiscal concerns. Naoya Hasegawa, chief bond strategist at Okasan Securities, highlighted the uncertainty surrounding fiscal and monetary policy, noting that an early recovery in investor demand is unlikely. Takuji Okubo, managing director and chief economist at Japan Macro Advisor, suggested Japan still has time to address its fiscal situation, though he acknowledged other countries face more severe challenges.
