Asian stocks plunge as global bond sell-off deepens

A sweeping sell-off in global bond markets combined with surging oil prices sent stocks tumbling across the world this week, with Wall Street posting its third straight day of losses on Tuesday and Asian markets extending the decline sharply on Wednesday.

The S&P 500 fell 0.7% on Tuesday, the Dow Jones Industrial Average dropped 0.8%, and the Nasdaq Composite slid 1%, according to the Associated Press. Technology and semiconductor stocks bore the brunt of the selling, with Nvidia ↗ 0.84% falling 1.5%, Amazon Amazon.com, Inc. ↘ 0.15% losing 1.9%, and Advanced Micro Devices ↗ 4.69% declining 2.4%.abcnews+1

Asian Markets Extend the Rout

The damage deepened overnight. Tokyo's Nikkei 225 dropped 3%, South Korea's Kospi lost 3.6%, and Hong Kong's Hang Seng slipped 0.8%. In India, the Sensex fell more than 780 points in early Wednesday trading while the Nifty 50 dropped below the 23,800 level. European markets also declined on Tuesday, with the UK 10-year gilt yield surging to an 18-year high.etvbharat+2

The sell-off is being driven by a convergence of forces. Bond yields have climbed to multi-year highs across four continents simultaneously. The 10-year U.S. Treasury yield rose to around 4.80%, its highest since 2023, up from 4.20% at the start of 2026. Japan's 10-year government bond yield hit 3% for the first time since 1996, while Germany's 10-year bund yield reached a 15-year high.tradingview+2

Oil and Geopolitics Fuel Inflation Fears

Escalating hostilities between the United States and Iran have pushed crude oil prices sharply higher, compounding the inflation anxiety driving the bond sell-off. Brent crude has climbed toward $96 a barrel, up from roughly $72 before the conflict began in late February, as the Strait of Hormuz — through which about 20% of the world's oil is typically shipped — remains largely closed.abcnews+1

The combination of rising energy costs and elevated borrowing rates has complicated the Federal Reserve's inflation fight. With inflation still running above 3%, markets are now pricing in a 65% chance of a rate hike at the Fed's September 15-16 meeting. Fed Governor Michael Barr added to the hawkish tone on Tuesday, saying the central bank should "act decisively to raise interest rates" if inflation does not moderate.tradingview

Fiscal Concerns and G-20 Tensions

Growing government debt is amplifying the bond market stress. U.S. national debt surpassed $40 trillion two weeks ago, and defense spending tied to the Iran conflict along with rising interest payments are consuming an increasing share of federal spending. The Wall Street Journal News Corp ↘ 2.36% reported that the G-20 finance ministers' summit in Asheville, North Carolina, was overshadowed by the bond sell-off and disputes over tariffs, with Treasury Secretary Scott Bessent facing questions about the administration's economic strategy.wsj+1

Fed Chairman Kevin Warsh, who set the tone for the current sell-off with hawkish remarks at Jackson Hole last Friday, attended the summit as he weighs the September rate decision. Goldman Sachs ↗ 0.07% CEO David Solomon said at the summit that his outlook remained "pretty constructive" but acknowledged headwinds from Middle East conflicts and trade wars.wsj
