A sell-off in Japanese government bonds accelerated Thursday, pushing the benchmark 10-year yield to its highest level in over a decade as traders bet that persistent inflation will force the central bank to normalize policy sooner than expected.
Japanese government bond prices fell for a third consecutive session on Thursday, April 9, 2026, sending the 10-year yield up 5 basis points to 0.85% as concerns mounted that Japan's inflation is becoming entrenched.
"The persistent stickiness in service-sector inflation is a key concern for the Bank of Japan, and the market is pricing in a faster policy normalization path," said Kenji Tanaka, chief economist at Mizuho Research Institute in Tokyo. "The era of negative interest rates is clearly over, but the next step is a hawkish question."
The sell-off was broad-based, with the 2-year JGB yield rising 3 basis points to 0.30% and the 30-year yield climbing 6 basis points to 1.95%. This steepening of the yield curve suggests investors are demanding higher compensation for the long-term risk of inflation. The yen strengthened 0.2% against the dollar to 148.50, while the Nikkei 225 stock index fell 1.2%.
The move puts pressure on the Bank of Japan ahead of its next policy meeting on April 28. While the board has been cautious about tightening policy, continued yield rises could force it to abandon its yield curve control policy entirely. Markets are now pricing in a 40% chance of a rate hike at the April meeting, up from 15% just a week ago.
The latest sell-off in JGBs was triggered by the release of the Tokyo CPI data, which showed core inflation at 2.8% in March, exceeding the Bank of Japan's 2% target for the 24th consecutive month. More worryingly for the central bank, service price inflation, which is more reflective of domestic demand and wage pressures, accelerated to 2.5%, its fastest pace since 1993.
Wage growth has been a key focus for the BoJ. The spring "shunto" wage negotiations resulted in an average wage increase of 3.8% for major companies, the highest in three decades. While this is a positive development for the economy, it also fuels concerns about a wage-price spiral, where higher wages lead to higher prices, which in turn lead to demands for even higher wages.
The Bank of Japan is now in a difficult position. After decades of fighting deflation, it is now faced with the opposite problem. The central bank ended its negative interest rate policy in March, a landmark decision. However, it has so far been reluctant to signal further rate hikes, fearing that it could derail the fragile economic recovery.
The BoJ's yield curve control (YCC) policy, which aims to keep the 10-year JGB yield around 0%, is also looking increasingly untenable. The central bank has been forced to buy massive amounts of JGBs to defend the yield cap, leading to a distortion in the bond market. The last time the 10-year yield was at these levels was in 2014, before the BoJ embarked on its massive quantitative easing program. If the central bank abandons YCC, it could lead to a further spike in yields, which would increase borrowing costs for the government, companies, and households.
