Taiwan stocks fall as yields and oil rise

That matters particularly for Taiwan because the market is heavily weighted toward export-driven technology and semiconductor shares, which tend to trade as long-duration assets and are therefore sensitive to higher real yields. When U.S. bond yields rise, the discount rate applied to future earnings rises as well, making richly valued tech stocks harder to justify. That is a direct headwind for Taiwan’s index, even before considering the broader impact of a stronger dollar and weaker global appetite for cyclical risk.

The external backdrop was weak across the board. Wall Street fell on Tuesday, with the Dow, Nasdaq and S&P 500 all finishing lower as the U.S. 10-year Treasury yield touched its highest intraday level since July 2007. Markets are widely expecting the Fed to hike by a quarter point, according to CME FedWatch, but the bigger issue for equities is the signal from yields: inflation and policy are staying restrictive for longer than many investors had hoped.

Oil’s jump added to the pressure. West Texas Intermediate rose more than 4% after reports of fresh Houthi strikes and the shutdown of Saudi Arabia’s East-West pipeline, stoking concerns about inflation persistence and feeding back into the rate outlook. For Taiwan, that combination is awkward: higher energy costs worsen the import bill and can tighten global financial conditions just as its market tries to stabilize after a sharp run-up earlier in the year.

Technically, the market is also losing momentum. Taiwan Semiconductor Manufacturing Co., the index heavyweight and a key sentiment barometer for the market, has slipped below its 50-day moving average in recent sessions and its relative strength index has dropped into the mid-40s, a sign that buying pressure is fading. The iShares MSCI Taiwan ETF has similarly pulled back from its recent highs, reinforcing the view that foreign investors are reducing exposure to Taiwan-linked assets rather than rotating into them.

The near-term risk is that this becomes a broader de-rating rather than a brief correction. The bull case remains intact if the Fed tone is less hawkish than feared and if Taiwan’s semiconductor earnings outlook continues to support the market’s long-term premium. But the bear case is that higher U.S. yields, firmer oil and a stronger dollar keep compressing multiples before domestic fundamentals can reassert themselves.

For investors, the key question is whether this is a routine pause after a strong advance or the start of a longer valuation reset. If Treasury yields stay elevated and global growth sentiment worsens, Taiwan’s market may keep underperforming even if company-level fundamentals remain solid.
