According to Jin10, the Bank of Japan successfully maintained financial market stability on June 17, while the yen remained in a weak trading range. On Tuesday, USD/JPY fluctuated just 0.43 yen intraday, marking the smallest daily swing on a policy decision day since January 2021. The pair stayed above 160 on Wednesday morning, approaching the intervention level Japan's Ministry of Finance acted to defend in late April.
Investors remain vigilant about potential further intervention, especially as Finance Minister Katayama Tsugumitsu has repeatedly stated his team stands ready to act if necessary. Mitsubishi UFJ strategists noted that ongoing verbal intervention signals keep investors on alert for actual forex intervention, expecting USD/JPY to continue trading within a defined range.
