JGB 10y eases to 2.90% as Ueda and Takaichi face parliament
Japan’s 10-year yield fell 3bp to 2.90%, near five-week lows, on risk aversion after the US tech sell-off and Prime Minister Sanae Takaichi’s pledge to keep bond issuance under control, as BoJ Governor Kazuo Ueda said rate rises at an appropriate pace help prevent yield spikes.
Japan’s 10-year yield fell 3 to 2.90%, near five-week lows, on risk aversion after the US tech sell-off and Takaichi’s issuance pledge, as Ueda backed rate rises at an appropriate pace.
Both pitched credibility as the cure for high yields and a weak yen; with USD/JPY near 158, close to the 160 line analysts tie to intervention, words carry weight.
Next: national CPI on Friday 23 October, then the BoJ on 30 October, where a hold at 1.25% is expected and December is seen as the live meeting.
The trader’s angle
Japan’s central bank governor and prime minister made the same argument from different sides: credible policy keeps long-term yields in check. With USD/JPY near 158 and the BoJ due on 30 October, traders must judge whether words are enough.

A long-dated ’s bundles two things: where investors expect the Bank of Japan’s to be over the years ahead, and a for the risk of lending that long, which rises when investors fear inflation or heavy government borrowing.
That is why a central bank that looks behind the curve can push long yields up, not down. If markets come to believe inflation will overshoot, they demand more to hold long bonds. Raising rates steadily lifts short-dated yields but reassures holders of long ones, which tends to flatten the . Ueda made the argument about long yields in parliament on Monday; the point about the curve is an inference, not his claim.
What happened
Japan’s central bank governor and its prime minister spent Monday answering questions in parliament about the same problem: high bond yields and a weak yen.
Bank of Japan Governor Kazuo Ueda said underlying inflation is very close to the Bank’s 2% goal, with AI-related demand and a tight labour market adding to cost pressure from the Middle East. Raising rates at an appropriate pace, he argued, would help avoid spikes in bond yields. Failing to adjust could push long-term rates up if markets came to fear an inflation overshoot.
Prime Minister Sanae Takaichi firmly denied that she is driving the weak yen and high interest rates. Confidence in the yen, she said, rests on a strong economy and sustainable public finances. She pledged to keep issuance under appropriate control in next fiscal year’s budget, answering an opposition question about a second supplementary budget.
Bonds rallied. The 10-year yield fell 3bp to 2.90%, near five-week lows. Two things helped: a mood after the sell-off in US tech stocks, which sent investors into safe bonds, and the issuance pledge, which would leave the market fewer new bonds to absorb. USD/JPY was steady near 158 at 06:52 GMT.
Why it matters for traders
Both are arguing about the long end. Under Takaichi’s government, JGB yields have hit multi-decade highs and the yen has fallen to its weakest since 1986. Ueda’s answer is a , a rule for how the Bank responds: keep raising rates at an appropriate pace so that investors don’t demand a bigger for inflation risk.
If markets believe him, rate rises push up short-dated yields while long-dated ones stay anchored, which points to a flatter . Note what he didn’t offer. Emergency bond buying, he said, is for sharp spikes or a dysfunctional market, not for holding yields at a chosen level.
Takaichi is working on the supply side of the same problem: fewer new bonds would ease the pressure on long yields. But her pledge covers next fiscal year’s budget, so there are no numbers yet.
The funding questions are real. The opposition is asking about a second supplementary budget, and a planned cut in the consumption tax on food from April 2027 still has to be paid for. Her cabinet’s approval rating has fallen to 49.1%, the lowest since she took office, according to a Kyodo poll.
The yen is the other front. At about 158, USD/JPY is a couple of yen below the 160 level where analysts see the risk of as most acute. The wide gap between US and Japanese yields keeps supporting the dollar, because investors earn more by holding it.
Officials lean the other way. On 15 October, Finance Minister Katayama said she was ready to act again, with the US–Japan stance unchanged since their joint intervention in late July. Analysts describe the pair as yield-gap support colliding with intervention risk.
How it ripples through markets
How steady hikes are meant to calm the long end

Inflation pressure builds

Inflation fears stay contained
If markets trust the Bank to act, they stop fearing an overshoot and demand less extra yield to hold long bonds.

The government reins in supply
Takaichi pledges to keep JGB issuance under appropriate control in next fiscal year’s budget. Fewer new bonds would leave investors less to absorb, easing the pressure on long yields.

What to watch
Friday’s national CPI. September figures are due on Friday 23 October at 08:30 Tokyo time (00:30 in London). August’s headline rate was 1.9% and core 1.7%, and forecasts for September vary widely. A hot number would test Ueda’s claim that well-paced hikes keep long yields calm, and would add to the case for a December move.
The BoJ on 30 October. The policy rate is 1.25% after the hike on 18 September. Most expect a hold, with hints that leave room for 1.5% as early as December. Sources said on 13 October that officials lean against back-to-back hikes. The Outlook Report released with the decision will show how the Bank reads inflation.
The budget numbers. Takaichi’s pledge will be judged on next fiscal year’s issuance plan and on whether a second supplementary budget emerges. Watch the 10-year around 3%: a move back above it would say the market doubts the promises. And watch USD/JPY as it nears 160, where the risk of intervention rises.
