Japanese Finance Minister Satsuki Katayama said authorities may enter the foreign-exchange market if volatility or speculative moves emerge [1].
This stance signals Japan's intent to stabilize its currency through direct intervention, which can prevent drastic swings that destabilize national imports and economic planning.
Katayama said on May 29 [1] that the government is prepared to act. This follows similar remarks made earlier this month on May 19 [2], where she said that Japan stands ready to act against excessive foreign exchange volatility at any time [2].
"We can step into the market if there is volatility or evidence of speculative moves," Katayama said [1].
Officials are reportedly monitoring the situation to avoid unintended impacts on the U.S. bond market [2]. The balance between supporting the yen and maintaining stability in international bond markets remains a primary concern for the ministry.
Despite these warnings, Katayama has not confirmed specific recent actions. When asked if authorities intervened to support the yen last week, she said, "I have no comment" [3].
Currency intervention typically involves the central bank selling foreign reserves to buy its own currency, thereby increasing demand and raising the value of the yen. Such moves are often used as a deterrent against speculators who bet on a currency's decline.
“"We can step into the market if there is volatility or evidence of speculative moves."”
The Japanese government is using verbal intervention to discourage speculators from betting against the yen. By repeatedly signaling a readiness to act, the Finance Ministry hopes to stabilize the currency without actually spending its foreign reserves, though the mention of U.S. bond market impacts suggests a complex coordination effort to avoid triggering a broader global financial shock.
