gradually and is currently trading in the 159 range. Looking at G10 FX performance since July 3, when our previous KCV was published, the JPY remains only mid-pack

despite the intervention.

Because coordinated intervention has historically been

undertaken only in crisis situations, we had previously

viewed the likelihood of coordinated intervention as low.

Therefore, the coordinated action was clearly a surprise,

demonstrating that Japanese authorities do not want USD/

JPY to rally significantly beyond 160 yen, and that US

cooperation was stronger than expected. Against this

backdrop, market caution regarding intervention has
