As Taiwan and the U.S. engage in critical tariff negotiations, expectations for the NT dollar's appreciation have risen sharply. Despite the central bank governor's explanation yesterday, the NT dollar again broke past the 30 mark shortly after opening today. This has rekindled concerns of foreign exchange losses for export industries, causing the Taiwan stock market to open lower and dip by as much as 183.43 points to 20349.56 at one point. However, both the stock and forex markets stabilized, with the NT dollar holding above the 30 threshold and the weighted index several times flipping to positive territory, ultimately closing down 10.40 points at 20522.59, with a transaction volume of NT$302.9 billion.

The U.S. stock market also faced declines, with all four major indices closing lower on Monday. The Nasdaq dropped 133.49 points or 0.74% to close at 17844.24, while the Philadelphia semiconductor index fell by 40.88 points or 0.93% to 4356.18. NVIDIA saw a slight dip of 0.59%, ending at $113.82, while TSMC's ADR fell by 1.61% closing at $176.4. This morning, TSMC's stock price hit a low of 916 NT dollars, dropping 2.3%, but later large buy orders helped stabilize the price, closing with an overall decline of about 11 NT dollars at 920.

Among market performances, ASE Technology Holding rose by 2.5 NT dollars to 136.5 NT dollars, and Foxconn was up 2.46% to 146 NT dollars. AI server-related stocks also rebounded, with Quanta up 3.04% at 254 NT dollars and Wistron rising 5.31% at 109 NT dollars. However, MediaTek fell by 1.6%.

Investors are continuing to monitor the impacts of the NT dollar's appreciation on potential forex losses. Leading life insurance firms Fubon Financial and Cathay Financial saw declines of over 1% this morning but ended up positive, with Cathay rising 2.19% to 55.9 NT dollars, while Fubon fell by 1.25% to 79 NT dollars. However, analysts noted that the recent rapid appreciation of the NT dollar lacks clear signs of halting, and with the semiconductor tariff updates coming this week, Taiwan stocks may face downward pressure. Thus, it is advisable to reduce positions and lock in profits in the short term until uncertainties ease.
