Asia stocks' chip-driven gains fade as Middle East tensions simmer

Asia equity markets lost the early momentum provided by semiconductor shares as geopolitical risks in the Middle East kept trading volatile and investors awaited further clarity on potential U.S.-Iran talks. Tokyo’s Nikkei briefly climbed above the 60,000 mark in intraday trade before giving back gains, while other regional benchmarks showed mixed intraday moves.

Market activity was driven by energy headlines: front-month West Texas Intermediate futures traded in the mid-$90s while Brent hovered just above $100 a barrel, reflecting sensitivity to reports of incidents in the Strait of Hormuz. Newswire reports said Iran attacked three vessels in the waterway and escorted two to Iranian waters; the White House press secretary Karoline Leavitt said those actions did not constitute a breach of the cease-fire. Early strength in chip-related stocks—particularly names tied to artificial intelligence demand—lifted some markets, but the advance proved fragile.

The immediate market reaction suggested the chip-led rally was more a short-covering and sentiment spillover from U.S. gains than a broad-based conviction shift. Saxo Markets’ chief strategist Charu Chanana noted that any upward move in oil prices can quickly knock Asian equities off their intraday highs. In South Korea, the Kospi initially rallied on semiconductor stock strength before paring gains; China’s Shanghai Composite and Hong Kong’s Hang Seng showed relative weakness amid the risk-off headlines.

In a broader economic context, disruptions around the Strait of Hormuz raise concerns about energy supply security and potential upside risks to inflation, which in turn affect global monetary policy outlooks. Research notes from regional banks and institutions pointed out that while an indefinite extension of an existing cease-fire would be positive, there is little evidence of a near-term durable resolution, leaving energy markets and risk assets on edge until the passage reopens or diplomatic progress is confirmed.

Looking ahead, analysts expect market direction to hinge on news flow from diplomatic channels, further moves in oil prices, and corporate results—particularly from major semiconductor suppliers. If talks between Washington and Tehran advance, risk sentiment could recover and chip stocks may resume leadership; conversely, renewed incidents in shipping lanes or higher-for-longer oil could trigger further equity retracements. Investors are advised to monitor liquidity conditions and position sizes given elevated volatility.
