Japan's Finance Official Mitsumura Jun said Thursday that decisive measures may be necessary to stop the yen's sharp slide against the U.S. dollar.

The warning comes as the currency's rapid depreciation threatens economic stability by increasing the cost of imports and fueling inflation. The government is attempting to signal to markets that it will not tolerate unchecked volatility.

Speaking during a press briefing in Tokyo, Mitsumura addressed the currency's movement into the 160-yen per dollar range [2]. He said that while some observers believe the yen's depreciation has eased, the currency continues to trade at that level [2].

"It is about time that decisive measures become necessary," Mitsumura said [1].

The Japanese currency has faced significant pressure, with the exchange rate reaching 160.41 yen per dollar [1]. This level of weakness has prompted the Ministry of Finance to monitor market trends more closely to determine if direct intervention is required.

Mitsumura said that the government's patience is limited regarding the current trajectory of the exchange rate. He said that if the current situation persists, decisive action will likely be required [3].

Market reactions to the official's remarks have been mixed. Some reports indicate the yen's depreciation eased following the comments, while other data shows the currency continued to weaken toward the 160-yen mark [2].

It is about time that decisive measures become necessary

The warning from the Ministry of Finance serves as a verbal intervention, a common tactic used by Japanese officials to discourage speculators without spending foreign exchange reserves. By mentioning 'decisive measures,' the government is attempting to create a psychological floor for the yen to prevent a spiral of depreciation that could destabilize domestic prices.
