Japanese government bond yields extended their climb on Thursday, with the 10-year trading near 3.06 percent, as traders raised bets on further Bank of Japan tightening and Asian equities absorbed the pressure from a global bond selloff.
The move comes a week after the BOJ lifted its policy rate to 1.25 percent, the highest since 1995, in a 7-2 vote that followed months of pressure from energy-driven inflation and a weak yen. Markets now price a high chance of one more hike this year, with several economists expecting a December follow-up to the September move. It was the sixth increase since March 2024, and the first cycle of genuine normalization after decades in which Japanese rates were the world floor.
Hawkish comments from BOJ officials have reinforced the repricing. Board member Hajime Takata raised the possibility of outsized or back-to-back rate hikes, and Governor Kazuo Ueda said policymakers need to pay closer attention to upside price risks. The central bank justified the September hike by citing a risk that inflation deviates above its 2 percent target, and said it aims to stabilize underlying inflation around that level so price rises do not overshoot and damage the economy later. A hike to 1.25 percent also brings the policy rate within the BOJ own estimated range for Japan nominal neutral rate, which gives officials a defensible stopping point if they want one.
Demand for long bonds is holding, for now
A successful sale of 30-year Japanese government bonds this week eased one worry and indicated domestic demand remains firm. Pension funds have been increasing JGB allocations in anticipation of an accelerated hiking cycle, since higher yields make the long end more attractive to liability-matching investors. That domestic bid is doing real work: the same week saw the US 30-year Treasury yield push above 5.4 percent, its highest since 2004, as a global bond rout deepened on oil, growth and fiscal worries.
Japan has not been immune to that global dynamic. The 10-year yield touched levels not seen since 1996 earlier in the month before pulling back, and each BOJ hike cycle pushes the yield curve further from the ultra-low regime investors treated as permanent for a decade. Japanese life insurers and pension funds, which spent years hunting yield abroad, now face a domestic bond market that pays them again, and the repatriation trade is one of the sleeper risks global bond desks watch. The 40-year JGB yield sits above 4 percent, a level that would have been science fiction to a Tokyo bond trader in 2020.
The yen and the politics of tightening
The September hike followed unusual public pressure from Washington. US Treasury Secretary Scott Bessent had urged the BOJ to take decisive monetary steps to combat yen weakness, a level of direct commentary on Japanese policy that would have been unthinkable in earlier decades. The yen strengthened after the hike, though markets read the BOJ guidance as less hawkish than the move itself, and two dovish dissenters appointed by Prime Minister Sanae Takaichi kept investors guessing about the pace ahead.
Takaichi politics cut both ways. Her reflationist aides initially projected quarterly hikes through January, but the two dissents from her appointees, Toichiro Asada and Ayano Sato, signal a government uneasy about how fast tightening squeezes household borrowing and the fiscal budget. With Japanese debt-to-GDP the highest among major economies, every 25 basis points adds real money to the interest bill, and the BOJ balance sheet remains loaded with bonds bought during the easing years, which means rate hikes also raise the cost of the central bank own remittances to the government. Higher rates help savers, and Japanese households hold enormous deposit balances, but they also raise mortgage costs for a workforce whose wages have only recently begun climbing after a generation of stagnation.
What it means for global markets
Japanese yields matter far beyond Japan. Japanese institutions are among the largest foreign holders of US Treasuries, and rising domestic yields have historically pulled that money home, tightening global dollar funding at the margin. With the US long end already at generational highs and the Federal Reserve in a tightening stance, any marginal seller of Treasuries from Tokyo compounds the selloff rather than cushioning it. Central bank reserve managers have already voiced unease about Treasury market volatility, per Central Banking reporting this month, and a shrinking foreign bid is part of that worry.
Asian equities weathered the bond storm on Thursday, with oil retreating slightly and offering some relief on inflation expectations. Brent has been trading in the mid-90s to around $102 amid the Iran conflict, keeping energy-driven price pressure alive across importing economies, Japan among them. The BOJ hike and the bond repricing are two sides of the same oil story: imported energy costs pushed Japanese inflation up, which forced the central bank to respond, which now feeds back into global yield levels. The Swiss National Bank, facing the same imported energy inflation, held its rate at zero this week but lifted its inflation forecast, another sign of how the oil shock is cornering central banks that expected to be easing by now.
For crypto and risk assets, the direction of travel is the same as it has been all month. Higher global real yields raise the hurdle rate for assets that pay no cash flow, and the strongest crypto rally of the month has come in stretches when bond yields paused, not when they climbed. Bitcoin held near $84,400 on Thursday, per CoinGecko data, roughly flat as the bond market did the moving. The next BOJ meeting is October 29 and 30, and the December hike question will hang over Asian markets until then.
