JPMorgan: Yen Short Unwind Risks Dollar-Yen Below 155
JPMorgan strategists warn that a substantial unwind of yen short positions could rapidly strengthen the currency. This could happen if the dollar-yen rate falls below 155, risking further selling pressure.
Yen Short Unwind Could Accelerate Gains
JPMorgan Chase & Co. strategists caution that significant yen gains could accelerate if the dollar-yen rate strengthens past 155. A substantial unwind of existing short positions—bets on the yen falling—would drive this move. Strategists, including Junya Tanase, noted recent price action supports their view that large yen short positions remain outstanding.
This suggests potential for further selling, leading to greater yen appreciation than currently expected. JPMorgan estimates ¥16 trillion ($102.6 billion) to ¥17 trillion of bearish yen positions are still open, representing a substantial market exposure.
Potential Range and Recent Volatility
A complete closure of these bearish positions might theoretically push the dollar-yen rate into a 142–146 range. This warning follows one of the yen's sharpest rallies since joint Japanese and US intervention in late July. Earlier this week, the dollar-yen pair climbed to 160.39, its highest level since that operation. It then reversed sharply, dropping to 155.30, bringing the pair very close to its post-intervention low of 155.23.
Catalysts for Yen Strength
Speculation about a Government Pension Investment Fund (GPIF) asset allocation shift and mounting expectations for faster Bank of Japan (BOJ) rate hikes fueled this recent rally. Market observers believe an unwind of speculative yen shorts and hedging demand from domestic investors amplified these catalysts.
This raises the risk that further yen gains could force more bearish positions to close, creating a feedback loop for the currency's appreciation.
However, JPMorgan believes expectations around both GPIF and BOJ actions “look a bit excessive.” The firm does not currently see a high probability of dollar-yen falling materially below its assumed 155–165 range for now. Asian investors should monitor the 155 level closely for potential volatility.
While a break below this point could trigger further short covering, JPMorgan's analysis suggests limited downside beyond this band based on current fundamentals.
