Asian stocks jump as chip rebound offsets Middle East risks

Asian stocks opened higher on Wednesday but traded in a mixed fashion as investors weighed a sharp rebound in semiconductor shares against rising geopolitical risks in the Middle East, where Yemen's Houthi rebels have declared a maritime blockade on Saudi Arabia.

Chip Stocks Lead Early Gains

South Korea's Kospi surged more than 6% at the open before paring gains, as beaten-down semiconductor names rallied in the wake of Wall Street's strongest session in three weeks. SK Hynix, which listed American depositary receipts on Nasdaq ↗ 0.27% earlier this month, led the charge in Seoul after its U.S.-listed shares closed sharply higher overnight. Japan's Nikkei 225 gained 1.9% in early trade, buoyed by the same tech-driven momentum.money.usnews

The moves followed Tuesday's rally on Wall Street, where the S&P 500 rose 0.9% and the Nasdaq Composite climbed 1.4%, snapping a three-day losing streak. The Philadelphia SE Semiconductor Index finished with a 5.2% advance — its second consecutive gain after confirming a bear-market decline late last week, having fallen more than 20% from its late-June record high.spokesman+1

Oil and Geopolitics Temper Optimism

Gains across Asia remained uneven as rising oil prices kept investors cautious. Brent crude had swung wildly in recent sessions, briefly topping $91 a barrel on Monday before pulling back below $87 after reports of a proposed 10-day U.S.-Iran cease-fire. The Houthi rebels' formal declaration of a naval blockade against Saudi Arabia on Monday added a fresh layer of risk to already fragile energy markets.morningstar+2

Reuters reported that a successful closure of the Bab el-Mandeb Strait could push oil prices above $115 a barrel, though analysts noted workarounds could limit the impact. Bloomberg reported that oil traders were weighing the competing dynamics of continued U.S.-Iran hostilities and diplomatic efforts to broker a new ceasefire.reuters+1

Earnings and Policy Risks Ahead

Investors were also positioning ahead of a busy earnings slate, with Alphabet ↗ 0.78% scheduled to report results later Wednesday. Bloomberg reported that U.S. equity futures edged lower in Asian hours ahead of the report.youtube+1

The broader backdrop remains volatile. The semiconductor index, despite its July selloff, is still up roughly 65% year to date, and chipmakers are expected to drive nearly half of S&P 500 profit growth in the second quarter. Meanwhile, the yen hovered near a four-decade low against the dollar, and new pharmaceutical tariffs imposed by the Trump administration added another variable for markets to digest.youtube+2
