A sharp surge in the Japanese Yen on Thursday fueled widespread speculation that Japanese authorities intervened in the currency markets to support the Yen, following USD/JPY's plunge of nearly 480 pips below the key 160 level. This move, which has not been officially confirmed by Tokyo, triggered significant volatility across major currency pairs and led to a broad selloff in the US Dollar Index (DXY), which dropped nearly 0.80% to around 100, its lowest since June 17 [1][2][4]. The Yen's strength was also evident against the Australian Dollar, with AUD/JPY falling roughly 1.75% to 111.70, its lowest since July 3 [4].
The suspected intervention came as Japanese officials had previously warned of readiness to act against excessive currency moves, and Reuters reported authorities were considering unannounced interventions [4]. The Japanese Yen was the strongest performer among major currencies, gaining 2.53% against the US Dollar and posting similar gains versus the Euro, Pound, and others [1][4].
The US Dollar's weakness was compounded by disappointing US economic data. Second-quarter GDP grew at an annualized pace of 1.5%, missing the 2.1% forecast and slowing from the previous quarter's 2.1% [1][2][3]. The Core Personal Consumption Expenditures (PCE) Price Index, the Fed's preferred inflation gauge, rose just 0.1% in June, below the 0.2% consensus, with the annual rate easing to 3.3% from 3.4% [1][3]. Headline PCE inflation also slowed to 3.7% from 4.1% [2][3]. These data prompted traders to trim bets on a September Fed rate hike, with the CME FedWatch Tool showing a 55% probability, down from 60% before the data [1].
In Europe, the Euro strengthened as Eurozone GDP outpaced forecasts, expanding 0.4% QoQ and 1.0% YoY, with Germany, France, Italy, and Spain all posting positive growth surprises [3]. The British Pound also rallied after the Bank of England held rates at 3.75% in a 6-3 vote, with three members favoring a hike and Governor Andrew Bailey signaling readiness to adjust policy if needed [2].
Looking ahead, markets are focused on the upcoming Bank of Japan decision, with expectations for no change in policy, and the release of the Tokyo CPI and Unemployment Rate [4]. In the US, the University of Michigan Consumer Sentiment is due next [2].
CONCLUSION
Suspected intervention by Japanese authorities sparked a dramatic rally in the Yen and broad-based weakness in the US Dollar, amplified by softer US economic data. The event triggered high volatility across global FX markets, with the Euro and Pound also benefiting from positive regional developments. Market participants remain alert for official confirmation from Japan and upcoming central bank decisions.
