Semiconductors drove the day’s risk reset, with Taiwan’s market falling more than 6%, the Nikkei losing about 4%, and MSCI Asia-Pacific ex-Japan declining more than 3% at one point. The selling spread into U.S. hardware and chip names including Seagate, Dell, Western Digital, and Marvell, pushing the Nasdaq Composite down about 1.3% to 26,289.71 in the most heavily cited close.

The reversal was not uniform. SK Hynix’s planned $29 billion share buyback helped limit damage in parts of Asia, while Google’s reported $12.2 billion AI-chip deal with Marvell sent Marvell shares sharply higher and reinforced the longer-term infrastructure-demand case. That contrast points to a market becoming more discriminating: AI spending remains powerful, but high-multiple semiconductor exposure is no longer trading as a single, unquestioned theme.

The 30-year U.S. Treasury yield touched roughly 5.33%, its highest since 2007, before easing to about 5.29%; the 10-year remained near 4.73%. The move reflected broader sovereign-bond pressure as investors weighed swelling government debt, sticky inflation, and geopolitical risk. U.S. federal debt passing $40 trillion sharpened concern that higher borrowing costs could enlarge deficits and create a self-reinforcing fiscal burden.

Treasury doubled its debt buybacks in an effort to support market functioning, but the intervention did not erase the underlying repricing. Domestic data offered no clear growth escape hatch: July industrial production rose 0.2%, while housing starts were 1.239 million and pending home sales fell 2.3%. The combination leaves rate-sensitive housing and long-duration technology shares exposed even as industrial activity remains resilient.

Brent crude rose to about $91.02 and WTI to roughly $84.94, their highest levels in more than three weeks, as the UAE cut economic ties with Tehran after accusing Iran of firing ballistic missiles at its territory. The United States also redirected cargo ships away from Iranian-affected routes, adding a direct supply-chain signal to the geopolitical risk premium. Strait of Hormuz disruption fears therefore moved from background concern toward a more tangible threat to fuel and freight costs.

Gold strengthened into the mid-$4,500s per ounce as investors sought protection from the combination of regional escalation, inflation risk, and sovereign-yield volatility. Bitcoin, by contrast, climbed above $69,000 and approached $70,000, benefiting from optimism around U.S. crypto legislation and a broader rebound in risk appetite after yields eased.

President Trump delayed planned 50% tariffs on Canadian products by three days, saying a deal with Ottawa was close. The pause supported risk sentiment and Canada-linked assets by removing an immediate escalation from the market’s next decision point, but it did not settle the underlying dispute. The short timetable keeps trade policy as a live source of volatility for industrial, consumer, and cross-border exposures.

Other policy headlines were less immediate for markets but meaningful for sector framing. China sentenced Evergrande founder Hui Ka Yan to life in prison, underscoring the political intensity of the property-sector crackdown. Lowe’s cut its outlook as weak housing conditions weighed on do-it-yourself spending, linking elevated borrowing costs to a broader squeeze on rate-sensitive consumption.
