Taiwan Semiconductors Drive the Gain

Taiwan’s electronics sector rose 0.94% as contract chipmaker TSMC climbed 1.05% to NT$2,400.00. The company accounts for over 40% of total market value. Memory chip supplier Nanya Technology surged 7.46% to NT$425.00, while smartphone IC designer MediaTek gained 2.01% to NT$4,560.00.

Largan Precision, which supplies smartphone camera lenses to Apple, jumped 10% to close at NT$4,680.00, a six-year high. The company is entering the co-packaged optics business to tap AI demand. iPhone assembler Hon Hai underperformed, rising only 0.56% to NT$269.00.

Geopolitical Relief Boosts Regional Markets

The U.S. and Iran are scheduled to sign a peace agreement on Friday, easing geopolitical tensions that had weighed on markets. Japan’s Nikkei Stock Average hit 70,000 for the first time after the Bank of Japan raised its policy rate by 25 basis points to 1%. Emerging-market stocks climbed for a third day, holding near record highs as oil prices fell.

Taiwan turnover totaled NT$1.198 trillion (US$37.97 billion). Analysts noted that gains lagged the strong U.S. rally as some investors hesitated ahead of Wednesday’s June futures settlement.

Oil Prices Fall on Peace Deal Optimism

U.S. crude closed down 4.9% at $80.75 per barrel after President Trump authorized reopening the Strait of Hormuz. Vice President JD Vance told CNBC the strait will be opened “in a toll-free way for the long term.” Lower oil prices supported emerging-market sentiment and reduced inflation concerns.

The Dow Jones Industrial Average added 468.77 points, or 0.92%, for a record close of 51,671.03. The S&P 500 climbed 1.65% to 7,554.29, while the Nasdaq Composite rose 3.07% to 26,683.94.

Financial Sector Attracts Rotation Buying

Taiwan’s financial sector attracted rotational buying as many firms posted strong profits from investments. The sector benefited from improved sentiment and lower interest rate expectations following the geopolitical breakthrough. Taishin Securities analyst Tom Tang said optimism toward geopolitics continued to drive the local main board higher, though some investors remained cautious about possible volatility on settlement day.
