TOKYO, July 2, 2026, 22:15 JST
- The dollar slid to 160.78 yen after soft U.S. jobs numbers, down from Tuesday’s 40-year low for the yen at 162.66.
- Japan is moving to surprise interventions instead of warning markets ahead of yen-buying, Reuters reported, aiming to catch yen short sellers off guard.
- ING Groep NV AMS:INGA says there’s a 37% odds the dollar/yen will hit 165 by the end of July, going by options pricing.
The yen’s biggest move this week wasn’t from a clear signal of Japanese intervention—it was out of Washington. Dollar/yen dropped to 160.78 on Thursday after a soft U.S. payrolls print, down about 1.2% from Tuesday’s 162.66. Reuters called that earlier peak the yen’s weakest in four decades. Tokyo now gets a little breathing room, but the trade is still on: Japan’s Ministry of Finance wants short sellers looking over their shoulders for a surprise, not just guarding a level.
Reuters said Japanese officials are dropping their old habit of giving the market advance warning. According to sources, they’re now steering clear of setting any clear “line in the sand,” so traders don’t know when yen-buying might come. The idea is simple: make those betting against the yen face more event risk. Reuters
This is important since Japan’s last intervention only gave the yen a brief break. Officials spent a record 11.7 trillion yen, around $72 billion, between late April and early May. Reuters reported the boost faded fast, with the dollar rising again past the level where Tokyo had acted.
| Yen stress gauge | Latest read | Why it matters |
|---|---|---|
| Tuesday’s high for dollar/yen | 162.66 | Yen hit its weakest point in four decades. |
| Dollar/yen after payrolls | 160.78 | U.S. figures took some pressure off Tokyo, at least short-term. |
| April-May FX intervention by Japan | 11.7 trillion yen / $72 billion | Record move, but didn’t last long. |
| Odds of 165 by end of July | 37% | Options traders still expect a possible dollar/yen spike. |
| Japan foreign reserves | About $1.1 trillion | That latest yen rescue used around 6.5% of these funds. |
The first hint the new playbook was having an effect showed up before the payrolls release. The dollar dropped as much as 0.9% to 161.115 yen Thursday morning, before trading at 161.58. Japan’s Ministry of Finance wouldn’t comment. Some traders pointed to nerves about possible intervention or a rate check, but Reuters reported there was no confirmed rate check.
Derek Halpenny, who heads global markets EMEA research at MUFG under Mitsubishi UFJ Financial Group Inc (TYO:8306), called the situation “jittery price action.” Bart Wakabayashi, State Street Corp’s NYSE:STT Tokyo branch manager, told Reuters the initial move felt like someone was active in the market, but said he was leaning toward it being a “rate-check rumour.” Reuters
The dollar extended losses after U.S. jobs data missed forecasts. Nonfarm payrolls increased by 57,000 in June, well short of the 110,000 economists in a Reuters poll had predicted. Fed funds futures dropped the odds of a September Fed rate hike to 49%, down from 67% before the release. The dollar index lost 0.71%.
| Policy pressure point | Data point | Market read |
|---|---|---|
| BOJ policy rate | 1.00% | Still lagging well behind the Fed. |
| Fed funds range | 3.50%-3.75% | Wide gap, so dollar/yen carry trade is supported. |
| Big manufacturers’ Tankan index | +22 vs +17 in March | Best since March 2018. |
| Big non-manufacturers’ index | +37 | Strongest level since August 1991. |
| Firms’ 3- and 5-year inflation view | 2.6% | Still above BOJ’s 2% line. |
Chris Turner at ING said dollar/yen broke above this year’s highs near 162, touching marks last hit in the 1980s, and the “outlook for successful intervention remains poor.” ING added that with no intervention this week, markets may look to July 16-17 before Japan’s Marine Day on July 20, as long as U.S. data and Fed comments keep the dollar strong.

BOJ got a stronger footing to sound hawkish after the Tankan survey on Wednesday. Major manufacturers’ sentiment jumped to +22, topping forecasts for +16. Firms now plan to lift capital spending by 11.5% for the year through March 2027. Inflation expectations stood at 2.6% for both three and five years ahead—still over the BOJ’s target.
Political pressure on the yen is now less one-sided compared to past selloffs. Toshihiro Nagahama, who sits on Japan’s top government economic panel, said the BOJ should raise rates two more times, six months apart, to aim for a neutral rate near 1.5%. “Moderate BOJ rate hikes are important in rectifying excessive yen weakness,” he said.

The 40-year low in the yen has some investors watching for possible action from Japanese officials that could hit U.S. stocks and Treasuries as well as global markets, CNN Business reported. Cross-market risks seem clearer now—if the dollar/yen climbs back toward 165, traders face both option flows and a finance ministry that, according to Reuters, wants to keep markets guessing.
