While declining to comment on specific levels, Kato said authorities are “thoroughly monitoring” the market for excessive fluctuations or disorderly movements, language widely viewed as signalling heightened official concern.Such remarks are part of Tokyo’s well-established verbal intervention playbook—a calibrated effort to slow speculative selling and remind markets that authorities could act if volatility persists. The yen’s weakness, Kato acknowledged, carries “both benefits and disadvantages,” boosting exporters’ profits but burdening households with higher import costs. Historically, this kind of rhetoric precedes or substitutes for direct intervention by the Ministry of Finance and the Bank of Japan, depending on market conditions and political tolerance.In essence, Japan’s officials are attempting to stabilise expectations rather than set an exchange-rate target, leveraging communication as their first line of defence before any physical yen-buying operations are launched.
