Intervention only supported for one month! Yen breaks 160 again; how many more times can Japan step in?

The yen falls below 160 again, joint intervention effect fades quickly

At the end of August, the USD/JPY broke back above 160, basically giving up most of the appreciation achieved by the joint intervention at the end of July. From July 30 to August 26, Japan's Ministry of Finance injected approximately 15.4 trillion yen, or about $96.4 billion, to support the yen, marking a record-high monthly intervention. On July 31, the US Treasury made a rare move to join the action, marking the first time since 1998 that the US has coordinated to intervene in the yen. The joint intervention once pushed the USD/JPY down rapidly from near 164 to around 155, but just a month later, the exchange rate again approached 160, indicating that the intervention mainly altered short-term trading behavior rather than reversing the overall trend.
