Hedge Funds Chase Yen Strength Plays on Intervention Fears

Hedge fund demand for dollar-yen options that profit from a decline in the pair has increased after the currency moved past 160, amplifying intervention rhetoric from Japan’s Ministry of Finance.

The yen fell to its weakest level since July 2024 on Monday, prompting Japan’s top currency official, Atsushi Mimura, to warn that authorities may take decisive action in the foreign exchange market if current conditions persist. The move follows similar remarks from Finance Minister Satsuki Katayama on March 27, when the pair closed above 160.
