Yen rallies on soft US jobs data, fueling fresh intervention speculation

A softer US payroll report triggered the yen to surge more than 1% against the dollar, reaching a session peak of 156.68 before settling near 157.32. Market participants remain vigilant for any cues of official action, although State Street strategist Lee Ferridge said no direct intervention was observed. The rally follows a recent joint yen-buying operation by Japan and the United States, the first such coordination since 1998, whose effect has diminished in the days since.

The yen’s broader decline is attributed to a wide interest-rate differential with the United States, Japan’s substantial debt load, and ongoing geopolitical uncertainty. While the Bank of Japan kept its policy rate unchanged, swaps suggest a roughly 60% chance of a hike by September. Top currency official Atsushi Mimura reiterated that any response would be coordinated with monetary policy, and First Eagle Investments’ Idanna Appio cautioned that intervention alone may not reverse the trend. Bloomberg analysis estimates that about $34 billion was used in the July 31 intervention, following a possible $53 billion outlay the day before.
