Yen Trading Range Shrinks to 4.5-Year Low as Hedge Funds Slash Short Bets

The yen has shown an unprecedented level of stability in recent foreign exchange markets. In October, the monthly trading range for the dollar-yen exchange rate was the narrowest in four and a half years, according to the Nikkei on November 2nd. This narrow range, fluctuating between 156 and 158 yen, indicated a significant decrease in selling pressure on the currency.

As of October 27th, hedge funds held a net short position of approximately 14,000 contracts, or roughly 180 billion yen, which was one-eighth of the peak recorded in June during a period when the dollar-yen exchange rate exceeded 160 yen. The reduction in hedge funds' short positions is largely attributed to coordinated government interventions by the United States and Japan, including the latter's intervention in July.

U.S. Treasury Secretary Scott Bessent warned speculators against yen weakness, and Prime Minister Sanae Takaichi stated that Japan's stance was not one that encouraged reflationary policies. Analysts believe that concerns over the Japanese government's tolerance for yen weakness and its potential to hinder the Bank of Japan's policy normalization have also subsided.

Teppei Ino, a chief analyst at MUFG Bank, noted that hedge funds can no longer short the yen without fully preparing to face the risks involved. Unlike previous instances, the yen did not experience selling pressure following the Bank of Japan's monetary policy meeting on October 30th. Sumitomo Mitsui Banking Corp.'s Takumi Naya observed that investors are showing less enthusiasm for shorting the yen due to the lack of post-meeting selling events.

Shifts in real-demand transactions are also influencing the yen's trajectory. Export companies, which had been waiting for the dollar-yen rate to rise back to 160 yen, have started selling dollars and buying yen around 157 yen per dollar. This suggests that more companies are beginning to believe that the exchange rate may not return to the 160-yen range.

External risk factors, such as political and fiscal instability in France and volatility in the U.S. stock market driven by artificial intelligence (AI) rallies, are also contributing to a favorable environment for the yen. Akira Moroga, a chief market strategist at Aozora Bank, predicted that further declines in U.S. stock prices and interest rates could result in additional yen appreciation.

Shinji Kunibe, a lead fund manager at Sumitomo Mitsui DS Asset Management, pointed out the falling U.S. real interest rates and growing interest from overseas investors in Japanese government bonds, suggesting that the yen is being chosen as a safe-haven asset once again. However, structural pressures continue to hinder the yen's recovery, making a decisive move toward the 150-yen range challenging.

Dollar-buying demand from energy importers due to rising crude oil prices, overseas investment through the NISA scheme, and Japan's digital deficit are factors that may limit the yen's resurgence. Strategists expect the yen to remain in a narrow trading range in the near term, but they caution that prolonged low volatility could allow positions to accumulate, potentially leading to sharp movements in either direction if future policy changes or international developments occur.
