Japan has already spent probably around 10 trillion yen, which is very close to the amount spent in April and May 2024. There is still a chance for an additional round of intervention if USD/JPY approaches 160 again. In this round, it hasn't breached 155. Based on CFTC data, positioning is still skewed toward yen short positions, so the position covering is not complete yet. If we hit 160, there could be additional unwinding in yen short positioning, which could accelerate yen weakness, prompting another round of intervention.
The commitment to support the Japanese yen from Japanese authorities is quite strong. So I think there is a good chance for additional intervention as the yen approaches 160.
