Japan’s Yen Struggles Amid Economic Uncertainty

Investors had been placing an unprecedented bet on the rise of Japan’s yen in anticipation of a long-awaited economic recovery coinciding with projections of a U.S. economic slowdown. However, this optimism has given way to a cautionary tale in the age of Trump. Despite high hopes, the yen finds itself struggling at nine-month lows, catching investors by surprise as they retreat from their most substantial currency wager in nearly 40 years. The resilience of the U.S. economy to trade disruptions and the lack of further interest rate cuts have disoriented the speculators. Additionally, Japan’s new government’s stance on regulating rate increases has contributed to this unforeseen turn of events.

The failure of this favored bet is a stark reminder of how expectations have been consistently defied by the markets during the first eleven months of Donald Trump’s second term in office. It has also highlighted the persistent weakness of the Japanese currency, resulting in a costly misstep for investors who have chosen to hold onto yen, despite its low yield compared to other investment options. Bart Wakabayashi, a State Street branch manager in Tokyo, noted the anticipated interest rate alignment between the U.S. and Japan hasn’t materialized as smoothly as expected, leading to a shift from bullish yen bets back to a neutral stance over the past seven months.

The recent speculation of official intervention from Japan as the yen reached a nine-month low against the dollar has further clouded the currency’s outlook. Many market participants anticipate a sideways or downward trajectory for the currency, which has been on the defensive for nearly five years. Vaibhav Loomba, head of FX and rates at Klay Group in Singapore, expressed a lack of conviction in the market trend, emphasizing a preference for a weaker yen. This ambiguity surrounding the yen’s future value can be linked to the cautious approach of the Bank of Japan in raising rates amid the uncertainty brought about by U.S. tariffs.

Under the leadership of Prime Minister Sanae Takaichi, who assumed office in late October, Japan has adopted a strategy of low interest rates while increasing spending to propel growth. This proactive approach is seen as less favorable for the yen by James Athey, a fixed income portfolio manager at Marlborough in London. Simultaneously, with both U.S. and Japanese future interest rate expectations diminishing, the yen appears susceptible to further decline. Chandresh Jain, an emerging market Asia rates and FX strategist at BNP Paribas, believes the dollar may strengthen against the yen, utilizing options to wager on a yen devaluation beyond 155 per dollar in the coming weeks.

Despite the uncertainty surrounding the yen’s future, some investors remain committed to the Japanese currency amidst shifting global interest rate dynamics. However, the prevailing sentiment suggests that now may be the time for many to prioritize carry strategies, aiming to profit from interest rate differentials, ultimately leading to a selling of the yen. While the forecast for dollar/yen remains at 155 by year-end, the possibility of an overshoot to 160 in the fourth quarter of 2025 has gained traction, as suggested by Shusuke Yamada, Bank of America’s FX and rates strategist.
