Japanese Finance Minister Satsuki Katayama said for a third consecutive day that Japan is prepared to take decisive action to stabilize the yen [1].

This volatility threatens the Japanese economy by increasing import costs and eroding purchasing power, particularly as the currency reaches levels not seen in approximately 40 years [1].

The Japanese yen has plummeted toward 164 per U.S. dollar [1]. Recent trading data showed the currency at 163.99 yen per dollar during the previous night [1], while subsequent trades hovered around the 163.70 yen range [1]. Some market analysts suggest the currency could climb as high as 165 yen per dollar [2].

Katayama said that the government would respond appropriately whenever necessary, noting that this includes taking decisive measures resolutely [3]. The repeated warnings over three days reflect the urgency of the government's stance as the currency's slide accelerates [1].

The rapid depreciation is largely attributed to escalating tensions in the Middle East. These geopolitical risks have increased investor preference for safe-haven assets, driving up the value of the U.S. dollar while putting downward pressure on the yen [2].

Industry leaders have noted that the traditional benefits of a weak currency are diminishing. Eiji Hashimoto, Chairman and CEO of Nippon Steel, said that the structure where a weak yen helps Japanese manufacturing is no longer as prevalent as it once was [3].

While some reports suggested the yen remained in the high 159 range, primary data from the Tokyo foreign exchange market, and official reports confirm the currency is approaching the 164 mark [1, 2].

“Necessary measures will be taken resolutely.”

The Japanese government is utilizing 'verbal intervention' to discourage speculators from further selling the yen without actually spending foreign reserves. However, the admission from industrial leaders like Eiji Hashimoto suggests that the 'yen-carry trade' and export advantages are being offset by the rising cost of raw materials, making the current currency devaluation a net negative for domestic economic stability.
