US, Japan Intervene to Support Yen; Taiwan Dollar Weakens

The Japanese yen experienced a significant rebound on July 31, driven by coordinated intervention from Japan and the United States. This joint action successfully pushed the yen up from a 40-year low and caused the dollar index to drop below the 100 mark. However, the positive momentum for the yen did not extend to other Asian currencies, particularly the New Taiwan dollar.

In contrast to its regional peers, the Taiwanese dollar weakened against the U.S. dollar. This depreciation was attributed to a shift in foreign investor sentiment, leading to sell-offs in the market and subsequent capital outflows. The currency fell by 1.46角, making it the weakest performer among Asian currencies on that day.

The intervention highlights the authorities' efforts to stabilize the yen, which had reached historic lows. While the immediate impact was a stronger yen, the broader Asian currency market showed mixed reactions, with Taiwan's dollar experiencing notable weakness.
