Asian equities fell on Wednesday as markets grappled with heightened risk aversion following a renewed military flare-up between the U.S. and Iran and a fresh bout of weakness in chip stocks. The move lower came alongside a rise in oil prices and inflation readings that raised questions about near-term price pressures.
Wall Street provided a modest lead-in, with S&P 500 futures down about 0.2% as attention turned to a key U.S. consumer price index release due later in the day. Overnight developments in the Middle East and renewed declines in semiconductor names contributed to risk-off flows into Asian trading.
Regional markets reacted to a spike in crude prices after the U.S. and Iran exchanged a new round of strikes on Tuesday evening. That escalation followed Iran's earlier shooting down of a U.S. helicopter in the Strait of Hormuz this week, amplifying concerns over supply disruptions and commodity-driven inflation.
Japan - Tokyo benchmarks slid after producer price pressures surprised to the upside. The Nikkei 225 fell 1.1%, while the broader TOPIX eased 0.7%.
Japan's producer price index for May printed much hotter than expected, driven primarily by higher fuel costs linked to tensions in the Middle East. The hotter PPI reading raised worries that rising factory gate prices could filter through to the wider economy and increase the odds of the Bank of Japan moving toward higher interest rates. The central bank indicated it will discuss the possibility of raising rates at its meeting next week.
Technology stocks also weighed on the Nikkei. SoftBank Group Corp. plunged nearly 10% after reports that talks with potential creditors to obtain about $6 billion via a margin loan backed by its OpenAI stake had stalled.
China - Mainland indexes slipped as inflation prints painted a mixed picture. The CSI 300 dropped about 1.0% and the Shanghai Composite fell roughly 0.6%.
Chinese consumer price index data for May came in softer than expected, highlighting persistent weakness in household spending and demand. By contrast, producer price inflation surged in May at its fastest rate in nearly four years, with disruptions to Middle East supplies pushing up oil and other commodity costs. That divergence underscores a widening mismatch between supply-driven price pressures and weak domestic demand.
South Korea - The KOSPI was the weakest market in the region, sliding about 4% as heavyweight semiconductor stocks resumed declines. The chip sector, which had staged a modest recovery the previous session, remained under pressure after steep losses earlier in the week prompted profit-taking and lingering doubts about the durability of AI-led enthusiasm in the space.
Hong Kong and other Asian markets - Hong Kong's Hang Seng dropped 1.1%, helped lower by local technology names. Lenovo Group tumbled nearly 10% on reports that the PC maker planned to raise device prices as soon as next month.
Elsewhere in the region, Singapore's Straits Times declined about 1%, while Australia's S&P/ASX 200 was essentially flat. India bucked the downtrend: the Nifty 50 rose 0.4% in morning trade, supported by a gain of more than 1% in Reliance Industries after the company announced an AI data center tie-up with Meta Platforms.
Market implications - The recent hostilities and the associated jump in oil have added an inflationary vector to markets already sensitive to growth and technology-sector dynamics. In Japan, higher producer prices have fed concern that input-cost pressures could translate into broader inflation, potentially nudging central bank policy discussions. In China, the split between weak consumer demand and stronger producer prices points to lingering headwinds for an economy contending with uneven domestic demand and supply shocks.
Technology and semiconductor sectors were clear casualties of the risk-off sentiment, while energy-linked commodity moves and inflation prints elevated the policy risk backdrop for regional central banks.
Outlook - Investors will likely keep monitoring developments in the Middle East for their impact on oil and commodity prices, while U.S. CPI data later in the day could set the tone for global risk appetite. In the near term, markets remain sensitive to further developments in chip equities and whether producer price pressures begin to translate into wider inflationary trends.
