Mimura Warns Yen May Face Intervention as Strong Currency Alliance is Reiterated

Japan is maintaining a close watch on the yen, with its top currency diplomat Mimura reiterating that authorities remain concerned about the currency's underlying moves and are prepared to respond if necessary. The finance minister emphasized Japan's strong 'currency alliance' with the US, highlighting close coordination between the two countries.

Mimura pushed back against concerns that funding constraints could limit Japan's ability to conduct yen-buying intervention, stating he has 'absolutely no such concern.' He also highlighted the broader relationship between Japan and the US, describing their currency alliance as extending beyond foreign exchange to wider economic-policy cooperation and global supply chains.

The comments reinforce the risk that Japanese authorities could become more active if yen weakness becomes disorderly or continues to move further away from levels they consider appropriate. For markets, the key takeaway is that intervention remains firmly on the table, but yield differentials in favour of the US dollar will continue to provide support for the pair.
