The yen falls below 162; Japan's finance minister remains restrained in comments, and intervention signals may not have intensified yet.

The yen exchange rate has fallen to a 40-year low. Japanese Finance Minister Satsuki Katayama reiterated that she is ready to take appropriate action at any time, but her wording was cautious and did not send a clear signal of tough intervention. Market caution has increased, but the threshold for direct market intervention has not obviously lowered.

On Tuesday, the yen-dollar exchange rate fell below the 162 mark ahead of Katayama's statement, hitting the lowest level since 1986. According to Bloomberg, Katayama subsequently stated, "We are ready to take appropriate action at any time if necessary," maintaining previous wording. Meanwhile, Cabinet Secretary Minoru Kihara also made similar remarks, saying Japan will take appropriate action in the foreign exchange market if necessary.

It is worth noting that Katayama only mentioned the term "bold action" when asked—a phrase often interpreted by the market as a precursor to direct intervention—rather than using it proactively. This suggests that authorities may not be eager to send a strong warning to the market at present. Katayama also refused to comment on specific exchange rate levels, saying her communication stance "remained stable."

Currently, the yen has fallen to its weakest level since 1986, but the strength of policy signals from the authorities has not matched the extent of the decline. Katayama refused to comment on specific exchange rates and did not proactively strengthen her warning tone, which differs from the authorities' path of upgrading wording ahead of intervention in April.

Analysts point out that the core issue facing the market is whether the authorities' willingness to intervene requires a further weakening of the exchange rate or an acceleration in the pace of decline. Before clear signals emerge, traders may continue to seek the boundary between verbal warnings and actual actions.

Intervention threshold may not be reached yet; market remains cautious

Although the yen remains under pressure and Katayama's repeated verbal warnings have failed to effectively stop its decline, traders are still closely watching if the authorities will intervene in the market again. Historically, Japan launched a record intervention when the yen first broke below the 160 mark at the end of April this year.

Reports state that Katayama's remarks this time differ significantly from signals before the intervention on April 30.

At that time, Japan's top currency official Atsushi Mimura explicitly used the phrase "final warning," and Katayama herself warned traders "not to put down their phones," with a noticeably more urgent tone. By contrast, this statement was calm and did not show similar escalation.

According to reports, on the bilateral communication level, Katayama said that she had spoken with U.S. Treasury Secretary Scott Bessent last week, claiming that the conversation "strengthened cooperation between the two countries," and characterized it as a follow-up to the G7 meeting held in France the previous week.

Katayama also stated today that "in our last Japan-U.S. online meeting, we confirmed that bold action is also among the options." This wording is intended to indicate that the intervention tools remain within the scope of alternatives, but no further explanation was given about the timing or triggering conditions.
