Taipei: The U.S. dollar experienced a significant decline against the Taiwan dollar, falling below the NT$32 threshold for the first time in more than a month, driven by weaker-than-expected U.S. retail sales data for July, according to dealers. This drop in the U.S. dollar has propelled the Taiwan dollar to become the strongest currency in Asia for the day.

According to Focus Taiwan, the U.S. dollar depreciated against the Taiwan dollar for the fourth consecutive session, closing down NT$0.194 or 0.61 percent, at NT$31.852. This marks the first time the U.S. currency has closed below NT$32 since July 3, when it ended at NT$31.930. The decline was exacerbated by a downward trend in the U.S. dollar index, which fell 0.38 percent following a 0.6 percent drop in July retail sales, the largest decline in over a year.

Dealers noted that the retail sales data dealt a blow to the U.S. dollar, following weaker-than-expected U.S. inflation data for July released the previous week. Despite the Taiex, Taiwan Stock Exchange's benchmark index, closing only 0.10 percent higher, foreign institutional investors continued to be net buyers, purchasing NT$45.45 billion worth of shares, which further strengthened the Taiwan dollar.

Market participants are advised to keep an eye on the upcoming minutes of the Federal Reserve's July policymaking meeting, due on Wednesday, for more insights into the U.S. central bank's prospective actions. Additionally, monitoring the Taiex and the behavior of foreign institutional investors could provide further indications of the U.S. dollar's trajectory against the Taiwan dollar. Since the start of the year, the U.S. dollar has risen 1.30 percent against the Taiwan dollar.
