Japan's Yen Intervention Stabilizes USD/JPY, but Risks Remain

The Japanese yen has experienced its sharpest four-day loss in nearly two years, but the trend may be stabilizing. The USD/JPY pair lost -3.2% for August, marking its worst month in fifteen and most volatile trading range in six.

Japan's Ministry of Finance (MOF) intervention, backed by the US Treasury and supported by a new Fed repo facility, has increased the credibility of future yen-buying operations. This has left traders on high alert for opportunities to fade rallies.

The MOF has vowed to intervene again, with the Fed making it easier by opening a repo facility for Japan. This allows Japan to borrow US dollars against its Treasury holdings to buy yen instead of selling US Treasuries, removing a key constraint on future intervention.
