Yen strengthens after joint Japan-US currency intervention

11 sources

Japan and the United States intervened jointly on the currency market last week to support the yen. It was their first joint operation of this kind since 2011, according to Nikkei Asia.

What happened

Nikkei Asia dates the operation to Friday, 31 July, and reports it as coordinated between Tokyo and Washington.
Trump publicly confirmed the joint intervention, Handelsblatt and Bloomberg reported on Monday.
The yen has since climbed to 155 per dollar, with traders on alert for a repeat (Nikkei Asia).
Bloomberg reports that bearish positions against the yen now face unwinding risk.

The view from outside

German and British coverage centred less on the market move than on its status and durability: Handelsblatt reported the joint support on Sunday, 2 August only as apparent and led a day later on Trump's confirmation, while the Financial Times focused on the prospect of a repeat operation.

What could happen next

Open whether the yen holds near 155 without further buying; Nikkei reports traders positioned for another operation.
Volume, funding and mechanics of Friday's operation are not given in the available reports, all of them teaser-length.
A second joint operation would test how far Washington's support goes beyond a one-off signal.

How the camps see it

Japan: Tokyo says it will not hesitate to act again together with Washington if needed, according to Katayama, cited by Nikkei Asia and the Financial Times.
United States: Trump calls the US role in the yen intervention a signal of friendship, while Bessent warns of further joint action (Bloomberg).
