Japan yields climb as BoJ hike bets build
Japan's 2-year yield hit 1.975% this week, its highest since 1995, as swaps priced about a 36% chance of an October hike and a December move in full, after the Bank of Japan raised rates to 1.25% in September.
Japan’s 2-year hit 1.975% on 28 September, its highest since March 1995, after the Bank of Japan raised rates to 1.25% on 18 September.
Swaps give an October hike about a 36% chance and fully price December, and tighter Japanese policy is one of the forces behind this week’s global bond sell-off.
Watch BoJ board members’ comments before the October meeting, the yen and oil, and the 2-year near 2%. Disorderly bond markets could make the BoJ more cautious.
The trader’s angle
Expectations of tighter policy in Japan are one of the forces behind this week’s global bond sell-off. Japanese investors are big holders of foreign bonds and the yen has long funded trades around the world, so the BoJ’s next step matters far beyond Tokyo.

Traders don’t wait for a central bank to decide. They bet on its next moves in advance using linked to the overnight rate it sets. If a quarter-point hike is possible at a meeting and reflect about a third of that move, the market is putting the odds at roughly one in three. When a move is fully priced, the whole of it is already in the price.
Short-dated government bonds trade on the same bets, which is why the 2-year yield is a good gauge of where traders think rates are heading: when it climbs, the market expects more hikes. The catch is that if the priced hikes don’t arrive, those bets unwind fast.
What happened
Japanese government bond () yields are climbing as traders bet that the Bank of Japan has more hikes to come. The 2-year yield reached 1.975% on Monday, its highest since March 1995, and the 30-year yield stood at 4.18% on Thursday.
now imply about a 36% chance that the BoJ raises its again in October, to 1.5%. They fully price a move by December, so traders treat it as all but certain. That follows its quarter-point hike on 18 September to 1.25%, the highest since 1995, agreed in a 7–2 vote.
Thursday’s , the BoJ’s quarterly business survey, didn’t settle the October question. Large manufacturers’ sentiment rose to +24 from +22, the highest in eight years and a sixth straight quarterly improvement. That just missed the +25 forecast.
Midsize manufacturers improved to 23 from 17. Smaller ones rose to 14 from 9, while coverage pointed to weaker sentiment among service firms.
The backstory
The BoJ only ended in March 2024. Its next small step, a hike to 0.25% that July, combined with weak US jobs data to set off a violent unwind of yen-funded . On 5 August 2024 the Nikkei fell 12.4%, its worst day since 1987, and days later the BoJ’s deputy governor said it wouldn’t raise rates while markets were unstable.
The pace has picked up since. September’s hike came just three months after June’s, the shortest gap between hikes since negative rates ended. The BoJ’s reasons were higher crude oil prices and a weaker yen, which were raising import costs and threatening to push inflation back above 2%.
Yet the yen weakened rather than strengthened after the decision. The BoJ sent mixed signals about how fast it would go from here, and one outlet reported it signalled a slower pace ahead. A slower path means less extra return from holding yen, which weighs on the currency.

The world's bond markets feel it
upGlobal bond yieldsWith fewer Japanese buyers, foreign bond prices tend to fall and their yields rise. Expectations of tighter Japanese policy are one of the forces behind this week’s global sell-off, which has pushed US 10-year yields to 24-year highs and UK 30-year yields briefly above 6%.
Why it matters for traders
Japan’s rates are now a global story. Expectations of tighter policy in Japan are one of the forces behind this week’s global bond sell-off, which has pushed US 10-year yields to 24-year highs and UK 30-year yields briefly above 6%.
Japanese investors are big holders of foreign bonds. The more they can earn at home, the weaker the pull to buy Treasuries or gilts, and the greater the chance that some of that money comes home. That would leave fewer buyers for those bonds and push their yields up.
The yen matters too. It has long been a , borrowed cheaply to buy higher-yielding assets abroad. Higher Japanese rates make that borrowing dearer, and August 2024 showed how fast a yen trade can unwind. This time, though, the yen weakened after the hike: currencies trade the expected path of policy, not the last decision.
For rates traders, the live question is timing. December is fully priced; October is a minority bet at about 36%. A clear signal from BoJ officials either way would move the 2-year quickly, and the yen with it.
What to watch
The BoJ’s own words. With the Tankan leaving October open, comments from board members before the October meeting are likely to do most to move the odds. A hint of urgency about the yen or inflation would lift October pricing; an emphasis on patience would push bets back towards December.
Then the two pressures behind September’s hike. Oil eased on Friday, with slipping below $100, which takes a little heat off import costs; a further slide in the yen would do the opposite. Keep an eye on the 2-year too: at 1.975% on Monday, it was within a whisker of 2%.
And watch the global sell-off. In August 2024 the BoJ showed it would hold fire while markets were unstable, so disorderly bond markets could make it more cautious, not less.
