Yen Jumps on Weak US Jobs Data, Intervention Risk Lingers

The yen rallied sharply against the dollar on Friday after a much weaker-than-expected U.S. jobs report reignited speculation of official intervention, just days after Japanese and American authorities jointly stepped into currency markets to support the struggling Japanese currency.

The dollar fell as much as 1.1% to 156.68 yen and was last trading at 157.16, well below the 40-year high of 163.99 set in July. It was not immediately clear whether Japanese authorities were directly involved in Friday’s move, though analysts said the magnitude of the jobs miss itself justified a dollar selloff.

Nonfarm payrolls decreased by 23,000 jobs in July after a downwardly revised increase of 20,000 in June, the Labor Department’s Bureau of Labor Statistics reported in its closely watched employment report. Economists polled by Reuters had forecast a gain of 80,000 jobs, with estimates ranging from as low as 10,000 to as high as 140,000.

“The scale of the undershoot on payrolls means it makes sense for the dollar to be falling — look at the short end of the U.S. yield curve — so the currency moves look like they are fundamentally driven,” said Lee Hardman, senior currency analyst at MUFG, referring to the sharp drop in two-year Treasury yields.

“It’s very rare you get these negative prints, so it’s a big downside surprise that has definitely put a dampener on expectations for the Fed and we’d expect to see a significant reaction and a broad based dollar selloff,” Hardman added.

**Intervention Warnings**

The yen’s sudden jump came just hours after Japan’s finance minister said Washington and Tokyo had been “closely communicating” and would not hesitate to intervene in currency markets. The warning, delivered shortly after the payrolls data release, underscored the continued sensitivity around yen weakness.

The threat of intervention has loomed large this week. Last Friday, Japan and the United States conducted a coordinated yen-buying operation, confirming a rare bilateral effort to halt the yen’s slide. That action marked the first joint intervention between the two countries since the 1990s.

Friday’s market reaction echoed the dynamic seen before that coordinated move: a sharp, sudden appreciation of the yen amid suspicion that authorities may have stepped in. Analysts, however, noted that the fundamental trigger — a dramatic miss in U.S. employment — provided a clear rationale for dollar weakness without any official action.

The dollar’s drop also pulled it further from the recent highs that had prompted multiple rounds of Japanese intervention earlier this year. The yen has been under persistent pressure from the wide interest rate differential between the U.S. and Japan, with the Federal Reserve’s aggressive tightening keeping the dollar elevated.

Friday’s payrolls report added to signs that the U.S. labor market may be cooling more rapidly than expected, a development that could give the Fed reason to slow or eventually halt its rate hiking cycle. A slowdown in Fed tightening would diminish the yield advantage that has drawn investors to the dollar and away from the yen.

The scale of the downside surprise was stark. Not only did the headline payroll figure turn negative, but June’s gain was revised lower from the initially reported 57,000. Economists had been expecting a moderation in hiring, but the actual outcome was far below even the lowest estimate in the Reuters poll.

The yen’s rally Friday marked another volatile session in a currency market that has been buffeted by both fundamental shifts and the specter of official intervention. Traders remain on edge, with the possibility of further coordinated action if the yen resumes its slide.
