Asian equity markets suffered a sharp decline on Thursday, driven by a renewed sell-off in semiconductor stocks as investors braced for Taiwan Semiconductor Manufacturing Company's (TSMC) quarterly earnings report. The rout was most severe in South Korea, where the Kospi index tumbled approximately 6.4%, approaching bear-market territory.
South Korea's Chip-Heavy Market Bears the Brunt
The sell-off hit South Korea disproportionately hard due to the outsized weighting of semiconductor stocks in the domestic market. SK Hynix Tumbles 11% as AI Memory Boom-Bust Cycle Persists, while Samsung Electronics lost more than 8%. The steep declines triggered temporary trading halts in several major shares, amplifying the market's downward momentum.
Japan's Nikkei 225 dropped nearly 3%, reflecting regional contagion from the tech rout. Hong Kong's Hang Seng Index bucked the trend, posting modest gains as investors rotated into defensive sectors.
TSMC Faces an Unforgiving Earnings Hurdle
TSMC is expected to report net profit of approximately NT$632.6 billion for the second quarter, a 59% year-over-year increase that would mark a fifth consecutive record. The earnings call, scheduled for 2 AM New York time, will be scrutinized not just for headline numbers but for guidance on advanced chip packaging capacity, capital expenditure plans, and demand from key customers.
The market's elevated expectations were underscored by ASML's recent results. The Dutch lithography equipment maker lifted its 2026 sales forecast to between €43 billion and €45 billion after reporting €9.3 billion in quarterly revenue and €2.9 billion in net income. Despite this positive news, Asian chip shares continued to slide, suggesting that investors now demand more than earnings beats—they require evidence that AI infrastructure spending can sustain its acceleration into 2027 without creating excess capacity or diminishing returns.
Monetary Policy Adds Pressure in South Korea
The Bank of Korea compounded the market's woes by raising its policy rate to 2.75%, its first increase since January 2023. The move aimed to contain inflation, household debt, and pressure on the won after consumer-price growth exceeded 3% in both May and June. While the rate hike was widely anticipated, tighter domestic financial conditions create an uncomfortable backdrop for technology stocks whose valuations depend heavily on profits expected several years ahead.
Cooler US Inflation Supports Bonds, but Oil Keeps Markets on Edge
US producer prices fell 0.3% in June, the largest monthly decline in 14 months, driven by a 6.4% drop in energy costs. This followed softer consumer inflation data and reduced the market-implied probability of a Federal Reserve rate hike in July to roughly 10%. Short-dated Treasuries found support from the data, but the relief failed to revive demand for Asian chip shares.
Oil prices remain a persistent source of uncertainty. Brent crude held above $85 a barrel as escalating US-Iran hostilities threaten energy flows, making June's inflation data appear increasingly backward-looking. The combination of elevated oil prices and geopolitical risk keeps markets on edge.
TSMC's outlook now carries unusual weight for the region's technology trade. A confident forecast could stabilize the sell-off, but any caution on customer spending or capacity could deepen the decline, given the exceptionally high earnings bar set by the market.
