The recent sharp rebound of the Japanese yen is drawing global investor attention to potential ripple effects across financial markets. JPMorgan's Japan Securities Strategy Team believes that a stronger yen could alleviate upward pressure on Japanese government bond yields, potentially accelerating the recovery of AI and semiconductor stocks listed in Tokyo.
Strategists including Rie Nishihara noted that underperforming real estate stocks could also benefit from this trend. However, they cautioned that yen appreciation may negatively impact earnings in certain sectors, particularly transportation, logistics, and automotive industries.
JPMorgan's optimistic outlook on Tokyo's AI and semiconductor equities stands in stark contrast to Saxo Bank's perspective on global markets. Saxo strategist Charu Chanana warned that the rapid surge in the yen against the dollar could trigger unwinding of crowded, highly leveraged positions in global equities, putting at risk high-valuation software stocks, AI-related semiconductor companies, and rate-sensitive assets such as real estate investment trusts (REITs).
Chanana explained that many investors have traditionally borrowed yen at extremely low costs to invest in higher-yielding currencies and risk assets. Funds facing losses or rising margin requirements may first liquidate their most liquid and profitable holdings, regardless of whether the underlying companies' fundamentals have changed.
Over the past week, the yen has experienced its most aggressive appreciation since 2022. The currency broke through the key support level of 155 after surpassing 160 against the dollar, briefly touching 152.89 on Tuesday—a seven-month high last seen in mid-February.
Wednesday saw continued yen strength against the dollar, partly fueled by aggressive remarks from U.S. Treasury Secretary Scott Bessent. Bessent publicly challenged currency traders, stating he is actively pushing for yen appreciation and declaring himself the "house," warning yen bears not to bet against him. He cited his informational advantage and deep understanding of Japanese government and central bank policy moves.
Market dynamics show intensifying battles between bulls and bears. Hedge funds are aggressively going long on the yen, betting the exchange rate will break above 150 by year-end with some targets aiming as high as 140. Meanwhile, Japanese retail investors are counterintuitively increasing short positions, highlighting a growing divergence between institutional and retail participants.
The core driver behind this yen surge is a reassessment of the Bank of Japan's rate hike trajectory. Overnight index swap markets indicate traders have fully priced in a 25-basis-point rate increase at the September 18 meeting.
