Yen Jumps On Report Of BOJ "Rate Check" But It's "Too Little Too Late"
Update: (12:40pm ET)
The Bank of Japan, not to mentioned Scott "the House" Bessent, have been most displeased with the yen plunge following today's BOJ rate hike, and so they once again do what they do pretty much every other week now: intervene in the market.
As we said earlier (see below) when we predicted that some sort of central bank intervention was inevitable, the yen pared declines on Friday after Japan's Nikkei newspaper reported that the Bank of Japan had conducted a rate check in the foreign-exchange market.
Just as it was intended, the report immediately reversed some of the yen’s huge losses triggered earlier in the session by disappointment among traders who had wanted clearer guidance from the central bank on its plans to raise borrowing costs further to stabilize inflation, following a widely expected rate increase on Friday. Instead, what they got were two dissenters appointed by the ultradovish Prime Minister Sanae Takaichi, with two more members due to leave the board next year and likely also replaced by more dovish policymakers, thus kneecapping expectations for more rate hikes.
Such intervention is meant to squeeze speculative yen shorts and accelerate a move in thin markets, but its ability to produce a lasting reversal may depend on monetary policy. The Fed’s renewed tightening cycle threatens to keep the US-Japan rate differential wide even after Friday’s BOJ rate increase, preserving the incentive for investors to borrow in yen to fund higher-yielding positions elsewhere.
Speculative positioning is also lighter than before the previous intervention. Leveraged funds halved their bearish yen bets in the week through Sept. 8, according to CFTC data, leaving fewer short positions to squeeze if authorities step in again.
The Japanese currency was down 0.6% at 156.83 per dollar at about 12:30 p.m. ET after losing as much as 1.3% earlier in the session. The Nikkei reported that the BOJ inquired with market participants about exchange-rate levels, without saying where it got the information. Such a move has previously preceded official intervention.
“This is too little, too late,” said Win Thin, chief economist at Bank of Nassau 1982. “The BOJ had another chance to go big and they missed it, same as July. If they really wanted to boost the yen, they should have hiked more than expected and then intervene massively.”
As reported earlier, the yen had weakened to about 158 per dollar after BOJ Governor Kazuo Ueda sent mixed signals on the path for future rate hikes following the bank’s widely expected increase. While he said the stage for policy setting has shifted, he also said it was difficult to determine the terminal rate for the current tightening cycle. Analysts saw his remarks as falling short of the market’s increasingly hawkish expectations.
Japan has entered a holiday period through next Wednesday, when thinner liquidity could amplify the impact of any official intervention. Authorities used a similar window around the Golden Week holiday period this year, first stepping in after the yen weakened beyond 160 just before the holidays and then apparently intervening again during the thinly traded period.
Of course, neither of the previous interventions worked, and this one will fail as well.
Japan and the US conducted a coordinated yen-buying operation this summer, the first since 1998, raising the stakes for traders betting against the yen. Japan spent a record ¥15.4 trillion on intervention in the month through Aug. 26, according to Finance Ministry data. US Treasury Secretary Scott Bessent has since continued to signal support for a stronger yen.
Despite the coordinate global attempts to boost the yen, the fundamental pressures weighing on the yen remain in place, including Japan’s wide interest-rate gap with other major economies, concerns over the fiscal outlook under Prime Minister Sanae Takaichi’s expansionary spending plans, and - of course - the biggest debt load in history, where every rate hike will lead to much more interest expense.

Earlier:
The yen sank to a two-week low against the dollar on Friday after two policy makers at the Bank of Japan dissented from a widely expected decision to raise interest rates, extinguishing expectations for back-to-back hikes. Governor Kazuo Ueda now needs, at a minimum, to preserve expectations for a December move to prevent markets from unwinding most if note all of the tightening path already priced into rates.
While Japanese policymakers pushed rates to their highest level in 31 years at 1.25%, the move failed to boost the currency as traders felt there was a lack of explicitly hawkish guidance.
As a result of the dovish split, the yen tumbled and the US dollar rose more than 1.2% against the Japanese currency, hitting a a two-week high of 158.07 yen after wavering during BOJ Governor Kazuo Ueda's press conference. It was set for its biggest daily increase versus the yen since December and the largest weekly rally since September 2024.
Traders had already discounted the equivalent of another hike by year-end before today’s policy meeting, leaving a high bar for any hawkish surprise. The presence of two dissenters signals that support for another rate increase in October is weakening, with OIS assigning around a 20% probability to such an outcome. That leaves Ueda’s press conference carrying the burden of preserving expectations for a December hike and keeping the BOJ on a tightening path that at least matches the Fed’s recent pace.
"They've just clearly underwhelmed versus expectations here," said Ray Attrill, head of FX strategy at National Australia Bank in Sydney. "And I think that one of the more staggering aspects of it was that they couldn't even get the unanimous vote for that," he said. "That really raised eyebrows in the market."
"The statement offered little additional hawkish guidance to support bullish Japanese yen positions," said Frantisek Taborsky, currency strategist at ING. "The dissent from (Toichiro) Asada and (Ayano) Sato points to resistance against the fastest pace of rate increases in more than three decades and suggests they may increasingly act as a brake on further tightening."
According to Mizuho strategists, the dissenters raise concerns that further rate hikes become harder to deliver, potentially steepening the JGB yield curve. Senior strategist Masayuki Nakajima said that Friday’s two dissenters were appointed by Prime Minister Sanae Takaichi. Two more members are due to leave the board next year and could potentially be replaced by more dovish policymakers
“Should their successors come from the reflationist camp, four of the nine Board members would become dovish,” he says; “While that would still fall short of a majority, it could reinforce expectations that sustaining the tightening cycle may become more difficult in the future”
“If so, concerns that the BOJ is falling behind the curve could re-emerge, potentially leading to further curve steepening,” he added.
Commenting on the market reaction, Bloomberg's Ven Ram said that the decision was:
- marred by dissent from two policymakers who voted against the hike;
- there was none who called for a bigger margin of increase;
- and the accompanying statement, while vowing to continue raising rates, failed to signal a sense of urgency by not saying when they will come.
Japan’s benchmark rate still trails the neutral rate by a considerable margin, and without back-to-back interest-rate hikes, the yen will stay weaker for longer. Only the franc carries a lower interest rate in the G-10 economies, with the Swiss central bank due to meet next week. Should that monetary authority reiterate its preference for keeping rates at zero, it will engender low volatility in two of the major exchange rates that represent the preferred funding currencies.
After a slew of central bank meetings and with Brent crude headed for the first weekly decline this month, global bonds that were deeply oversold are finding some respite. Longer-dated gilts received a boost from the Bank of England’s plan to pause bond sales and stop selling securities that mature in 2049 or later. Gilts with a maturity of 30 years stand to benefit considerably, so an immediate follow-through of Thursday’s rally is likely even though the looming autumn budget realities may check the pace of gains.
Here are some other reactions to the split BOJ decision from Wall Street traders:
NAKA MATSUZAWA, CHIEF MACRO STRATEGIST, NOMURA SECURITIES, TOKYO:
"It's (the yen's decline) a knee-jerk reaction to the two dissent votes. The bottom line is I think it's not too hard for the BOJ to keep the currency pricing for market expectations of rate hikes, basically every three months. And I do think that's what the BOJ wants to keep, not necessarily suggesting an October hike."
RAY ATTRILL, HEAD OF CURRENCY STRATEGY, NATIONAL AUSTRALIA BANK, SYDNEY:
"They've just clearly underwhelmed versus expectations here. And I think that one of the more staggering aspects of it was that they couldn't even get the unanimous vote for that. I think that really raised eyebrows in the market. (There was) nothing to put the market more firmly on the sense of another increase in Q4. It's clearly on Governor Ueda to put the market back more firmly on that stance. If he fails to do that, then I think dollar-yen is headed higher. It's hard to believe that just on the back of one quarter-point the (US) Treasury Secretary is going to be jumping for joy and as willing to replicate what they did in August (by intervening). The risk here is that we're heading back up to 160."
BART WAKABAYASHI, BRANCH MANAGER, STATE STREET, TOKYO:
"They raise rates and the currency loses 100 points - I think the market is looking at the BOJ versus the G3 and G10 central banks and the interest rate spread is what is in play. I think it's important that the six-month cycle has been broken, and that leaves the market to say, hey, these guys are willing to act if they have to."But there is a factor where they need to keep up (with other central banks)...if (Ueda) is not as hawkish as the Fed (at the news conference), dollar/yen could really take off higher."
DAVID CHAO, GLOBAL MARKET STRATEGIST FOR ASIA-PACIFIC, INVESCO, SINGAPORE:
"The BOJ has finally shed its long-term status as a monetary policy outlier and is joining the ranks of the other major central banks. The market fully anticipated this rate hike, but it has to be taken in context with what's going on with the rest of the world. The BOJ, Fed and ECB have all hiked rates in the same month."
MASAHIKO LOO, SENIOR FIXED INCOME STRATEGIST, STATE STREET INVESTMENT MANAGEMENT, TOKYO:
"Markets should focus less on the statement and more on Ueda's press conference. Expect a neutral-to-slightly hawkish tone, emphasizing that every meeting remains 'live' from here given resilient growth, persistent inflation risks and a policy rate (real yield) that remains accommodative even at 1.25%.More broadly, Japan is increasingly participating in a synchronized global tightening cycle. The debate is no longer whether the BOJ hikes, but how far rates ultimately go as major central banks continue to grapple with sticky inflation, AI-driven investment demand and rising term premium. Combined with higher domestic yields and growing confidence in the BOJ's normalization path, more capital is likely to stay in Japan rather than flow abroad. The bigger story remains that Japan is gradually ceasing to be a marginal buyer of foreign assets, not because it is selling aggressively, but because domestic alternatives are becoming more attractive."
CAROL KONG, CURRENCY STRATEGIST, COMMONWEALTH BANK OF AUSTRALIA, SYDNEY:
"The fact that two BOJ board members appointed by Takaichi opposed a hike today suggests the government still leans against BOJ rate hikes. This, together with the lack of guidance on the future pace of tightening in the statement, triggered a sell-off in the JPY. As usual, Governor Ueda’s post-meeting press conference will provide more insights into the rate outlook. The risk is Ueda fails to match markets’ hawkish expectations, fuelling further JPY weakness. We expect a follow-up hike in December."
YUGO TSUBOI, CHIEF STRATEGIST, DAIWA SECURITIES, TOKYO:
"Overall, the decision is likely to be seen as dovish. There had been some concern, albeit limited, about a 50-basis-point rate hike, but that did not happen. With two dissenting votes, markets likely took the view that it would be difficult to assume the pace of rate hikes will accelerate rapidly. U.S. Treasury Secretary Bessent's negative comments on reflationary policy had also raised concerns about the potential economic damage from the BOJ becoming more hawkish than previously expected. Those concerns have receded, prompting a rise in stocks."
SHUN HONG LIU, CHIEF INVESTMENT OFFICER, HONG INVESTMENT ADVISORS, HONG KONG:
“Honestly, it is so hard to have a very strong view in this market, given things are so political everywhere else in the world. Just imagine Japan needing to get consent from the US for intervention—what can be done and what cannot be done will be coordinated by so many politicians. Last week, if you had asked me, I would have answered yes, it is the end of the yen carry trade (after the rate hike). But now I would answer no, as Takaichi confirms a 3.5% military spending target, while people suddenly believe that Warsh is an uber-hawk. So I just keep my eyes open and trade accordingly."
KANAKO NAKAMURA, ECONOMIST, DAIWA INSTITUTE OF RESEARCH, TOKYO:
"The expected dissent by two members suggests political pressure on the BOJ has not entirely faded. The reappointment of Minister Kiuchi in the cabinet reshuffle also signals continued support for expansionary fiscal policy, raising concerns that fiscal stimulus could add to inflation pressures."While the BOJ's statement showed readiness to address upside inflation risks, Governor Ueda's press conference will be key for assessing the future pace of rate hikes.With producer prices remaining elevated, oil prices rising on Middle East tensions, and a weak yen adding to inflation risks, we do not believe this rate hike alone will be sufficient. We expect the BOJ to accelerate rate hikes to roughly once a quarter."
PRASHANT NEWNAHA, SENIOR RATES STRATEGIST, TD SECURITIES, SINGAPORE:
"No real surprises from the BOJ decision to hike the target rate 25bps to 1.25%, and neither was the 7-2 split, with recent Takaichi appointees Sato and Asada voting against the hike. The statement retains most of the hawkish tone from the July Statement noting 'accommodative financial conditions are expected to be maintained' even after the hike, and the Bank 'will continue to raise the policy interest rate'. The Bank reiterated its concerns that underlying inflation could deviate upwards from its 2% target, but we don’t see a smoking gun supporting a back to back hike in October. We stick with our call for rate hikes roughly every quarter with the next 25bps hike in December."
TOHRU SASAKI, CHIEF STRATEGIST, FUKUOKA FINANCIAL GROUP AND FORMER BOJ OFFICIAL, TOKYO:
"It's a little bit surprising to see that the yen weakened after the announcement. Maybe some market participants were expecting intervention like the last time before and after the BOJ's decision.Probably some were surprised because two members opposed the decision and maybe some were expecting some mention of a 50 basis point hike. It's a bit difficult to meet market expectations. Ueda-san has to be very hawkish to keep the yen from depreciating, but I think it's a bit difficult for him to be so hawkish. He has to say that the BOJ will probably hike the policy rate again within this year. But I think it's difficult for him to say, so the market will take it as a dovish press conference."
ANTHONY MALOUF, EBURY, SYDNEY:
"The seven-to-two vote is a touch wider than a clean hawkish consensus would suggest. Dissenters Asada Toichiro and Sato Ayano argued that inflation and growth have not accelerated enough to justify tightening now. The more telling split, though, sits elsewhere. Board members Takata Hajime and Tamura Naoki opposed the outlook language from the opposite direction, arguing underlying inflation has already reached a level consistent with the 2% target, which points to appetite for a faster pace rather than a slower one. The yen sold off after the decision. We interpret this as markets focusing on the two dissents, suggesting the board is less united behind a faster pace than the vote count alone implies, rather than doubting the hike itself. That fits our own view that the BOJ will deliver further hikes at a steady quarterly pace, with the next move in December and another in the first quarter of 2027, taking the policy rate to its neutral level near 1.75%."
KENTO MINAMI, SENIOR ECONOMIST AT DAIWA SECURITIES, TOKYO:
"The overall impression of the statement was dovish. BOJ’s new board members Ayano Sato and Toichiro Asada dissented from the decision. They were chosen by Prime Minister Sanae Takaichi, which suggests difficulties in raising rates in the future as the BOJ will have new board members going forward. "The statement indicated that the BOJ would raise rates at least once every six months, but this was in line with market expectations that the BOJ would raise rates every three months. These two dissenters were a dovish factor, which is why the yen started falling right after the decision."
MASATO KOIKE, SENIOR ECONOMIST, SOMPO INSTITUTE PLUS, TOKYO:
"I think the statement was hawkish, but markets had expected something even more hawkish, which is why the yen weakened after the announcement. "What struck me as hawkish was the explicit reference to accommodative financial conditions, and the wording that the BOJ will continue to adjust the degree of monetary easing. It also clearly mentioned upside risks. In addition, the BOJ cited a range of factors — not just crude oil, but price increases linked to AI-related demand, the weaker yen, and the mutually reinforcing mechanism between wages and prices. Those elements made the decision look hawkish overall. I don't think (Sato joining Asada in dissent) will have an impact when it comes to the pace of rate hikes being delayed. Sato's dissent was in line with expectations, but I see it as opposition to the timing or pace rather than a blanket objection to rate hikes. It did not come across as outright opposition, which I think is positive for the BOJ as it proceeds with further rate increases."
HIROFUMI SUZUKI, CHIEF FX STRATEGIST, SMBC, TOKYO:
"The rate hike itself was in line with market expectations, but the two dissenting votes came as a modest surprise, as only some market participants had anticipated them. The outcome has somewhat tempered expectations for further rate hikes and conveyed a dovish impression. The pace of future rate hikes is likely to depend primarily on the views of the BOJ's leadership. We therefore do not expect the pace to differ significantly from current market expectations.The yen initially weakened following the decision, but attention now turns to Governor Ueda's inflation outlook and policy stance at the press conference."
FRED NEUMANN, CHIEF ASIA ECONOMIST, HSBC, HONG KONG:
"The tone of the statement, along with two dissenters on the decision to raise rates, leaves lingering doubts that Japan’s central bank will be cautious in tightening monetary policy further. In addition, new inflation numbers out this morning for August showed that price pressures remained unchanged in August, rather than accelerate. All eyes are now on the press conference to be held by Governor Ueda, with the market looking for hawkish reassurances that the BOJ is prepared to raise rates again soon. While back-to-back hikes appear unlikely, investors will look for clues as to whether officials are prepared to raise interest rates again in December. Given that the Fed has tilted into a more hawkish direction, the pressure remains for the BOJ to follow suit: Governor Ueda will have to follow-up today's rate hike with by keeping the door open for another hike before the end of the year."
Sellside reactions aside, Governor Kazuo Ueda said that with the price trend very close to the bank’s 2% target, authorities now need to ensure inflation doesn’t overshoot.
“It has become important to stabilize the rate of price increases at a level of around 2%,” Ueda said in a post-decision briefing. “In that sense, I believe the phase of policy has shifted to a new stage.” The bank should act preemptively to avoid being forced into a situation where rapid hikes might become unavoidable, he added.
Traders also remained alert to the risk of intervention to prop up the currency after Finance Minister Satsuki Katayama said Tokyo won't hesitate to conduct further coordinated action, following a joint US-Japan move to boost the yen in late July.
The yen rallied sharply in early September to its highest since February as traders bet the BOJ would embark on multiple rate hikes, although those wagers came under question on Friday.
The dollar rally against the yen helped the DXY dollar index climb 0.25% to 100.48, as broader currency markets remained focused on energy prices and the U.S. Federal Reserve. The index, which tracks the currency against six major peers, was up 1.4% for the week to around a six-week high after the US Federal Reserve hiked interest rates on Wednesday and signaled more increases could be coming.
Traders now see a roughly 55% chance of a quarter-point hike at the Fed's next two-day meeting next month, up from 27% a week ago, according to the CME Group's FedWatch tool.
Finally, it's worth noting that the BOJ dissenters directly jeopardized the plan of Steve Bessent for a stronger yen (and thus less fears of TSY selling to prop up the yen through intervention). According to Bloomberg, Warsh should "seriously consider a little Friday afternoon intervention to ensure that this bounce in USD/JPY makes a lower high than the prior ascent to just over 160."
Of course, the problem with constant meddling in market prices is the risk that the market tests you, forcing ever-more frequent action to keep things in line. At the very least anyone who stayed with the short-dollar trade has received a painful kick in the shin, which arguably will dissuade some punters from staying in the position the next time that the authorities step in.
