Joint U.S.-Japan Intervention Takes Effect as Hedge Funds Cut Yen Shorts by More Than Half
Nashnova编辑部
Since US and Japanese authorities coordinated FX intervention in late July, hedge fund yen short positions have shrunk by more than half to 59,526 contracts — yet the yen still fell about 1% this week to 159.35, erasing most of the intervention gains.
Shorts halved — so why is the yen still falling?
CFTC data show leveraged-fund yen shorts dropped 6.5% to 59,526 contracts in the week to August 11, more than halving since the late-July intervention.
Yet the yen slid roughly 1% this week, closing at 159.35 in New York — wiping out most of the rally that intervention produced.
This means → shorts are covering to cut risk, but fresh buyers aren't stepping in. The yen has fewer sellers; it does not have more believers.
Why are asset managers running faster?
Asset managers cut net yen shorts by 18,530 contracts to 24,215 over the same period — a far steeper drop than hedge funds.
Pioneer Investments strategist Paresh Upadhyaya said: "The market was heavily short yen and caught offside. Cutting exposure was the natural response."
In plain terms = asset managers fear being caught more than hedge funds do — the larger the position when authorities strike again, the bigger the loss, so they exit harder.
Where is the money flowing instead?
Sterling longs rose to their highest since February; Aussie-dollar net longs added 7,737 contracts to 45,727.
New Zealand dollar shorts hit an all-time CFTC record; euro net shorts grew by 4,622 to 77,671.
Overall dollar longs shrank to roughly $36.8 billion. This reflects a broader reallocation — money is leaving dollar and yen shorts not to buy yen, but to rotate into currencies like sterling and the Aussie where the carry trade looks more certain.
What comes next?
Whether yen shorts keep shrinking hinges on two things: another round of official intervention and a substantive shift in Bank of Japan policy signals.
Most of the intervention-driven rally has already been unwound; without follow-through, shorts may rebuild.
This means → the market is in a holding pattern — waiting for the central bank to show its hand rather than making its own call.
