Japan Bonds Slide on Inflation Fears After 10-Year Note Auction

Japanese government bonds (JGBs) declined on Tuesday as yields on the 10-year benchmark surged to 1.23%, up 12 basis points from the prior session, despite a successful auction of JPY 1.2 trillion in new 10-year notes. The auction saw strong demand with a bid-to-cover ratio of 2.71, indicating investor appetite remains intact, yet yields rose due to heightened inflation expectations. The 10-year JGB yield has climbed 15 basis points since early February, reflecting a broader re-pricing of BoJ policy risk. Market participants now price in a 68% probability of a BoJ rate hike by July 2026, up from 45% at the start of the year. This shift follows stronger-than-expected core inflation data, which held at 3.1% year-on-year in February, well above the BoJ’s 2% target. The yen weakened to 148.30 per USD, marking its steepest drop against the greenback in six weeks, as traders expect a more hawkish BoJ and higher global rates. The rally in U.S. 10-year Treasury yields to 4.32% and a rise in the CBOE Volatility Index (^VIX) to 17.8 further underscored global risk-off sentiment. Japanese equities, led by the TOPIX index, fell 1.3% as rising yields weighed on valuations. Fixed income investors across Asia are reassessing duration exposure, with Korea and Taiwan government bond yields also widening. The BoJ’s commitment to yield curve control (YCC) remains in place, but markets are increasingly skeptical about its sustainability if inflation persists. The central bank’s next policy meeting is scheduled for April 16, 2026, and any sign of policy normalization could accelerate bond sell-offs and currency volatility.
