Asian stock markets declined on Friday, July 24, 2026, as Brent crude oil prices surged past $100 per barrel. The spike follows attacks by Iran-backed Houthi militants on Saudi oil tankers in the Red Sea, fueling global inflation fears and increasing the likelihood of a Federal Reserve interest-rate hike by September.
Global financial markets are reacting to a volatile mix of geopolitical escalation and corporate earnings disappointments. The surge in energy costs, combined with new U.S. trade barriers and a selloff in artificial intelligence (AI) stocks, has pushed several major Asian indices into steep declines.
Red Sea Attacks and the $100 Oil Threshold
Energy markets hit a critical tipping point this week after attacks on two Saudi oil tankers in the Red Sea disrupted key shipping lanes. Brent crude shot as high as $102 per barrel, marking its highest price since May. While early Friday trading saw a slight dip to $97.58, the benchmark closed Thursday at $100.69, a 7% increase. Before the Iran war began in late February, Brent was trading around $72 per barrel. U.S. benchmark crude slipped 2.7% to $89.71 per barrel.
The instability is not limited to the Red Sea. Shipping through the Strait of Hormuz, the primary gateway to the Persian Gulf, has already been disrupted by fighting around Iran. Additionally, attacks at the Caspian Pipeline Consortium terminal on Russia’s Black Sea coast have threatened the export of most Kazakh crude. With global inventories depleted by months of conflict, the risk of a supply squeeze is mounting.
Round 2 of the military conflict is going to be broader than Round 1,
Bob McNally, president of Rapidan Energy Group and a former White House official, said in a Bloomberg Television interview, referring to the Iran war.
President Donald Trump has responded to the instability by threatening major military punishment against Houthi rebels if the attacks continue.
Asian Market Contractions and Currency Volatility
The oil spike acted as a catalyst for a broader retreat from risk assets across Asia. South Korea’s Kospi was among the hardest hit, falling 5.7% to 6,690.62, with chipmaker SK Hynix dropping 8.3% and Samsung Electronics sinking 7.6%. In Tokyo, the Nikkei 225 declined 2.7% to 64,611.15, led by a 7.1% tumble for SoftBank Group.
Other regional losses included:
- Taiwan’s Taiex: Lost 2.7%
- Hong Kong’s Hang Seng: Dropped 1% to 24,963.23
- Shanghai Composite: Shed 1.6% to 3,814.20
- Australia’s S&P/ASX 200: Lost 0.8% to 8,772.30
This market instability has spilled over into currency exchange. The U.S. dollar index rose to around 101.46 and reached a 40-year high against the Japanese yen, with one dollar buying 163.79 yen early Friday, down from 163.85 yen—a level last seen in 1986. The euro rose to $1.1382 from $1.1377. In Europe, Britain’s FTSE 100 was up 0.5% to 10,690.09, France’s CAC 40 climbed 0.4% to 8,331.18, and Germany’s DAX gained 0.8% to 24,952.52.
Analysts suggest that efforts by Japanese officials to support the currency are currently futile. Tony Sycamore noted that against the backdrop of rising energy prices and the yen losing its safe-haven status, statements by Japanese officials about willingness to intervene or rapid BoJ rate hikes are unlikely to grab the market’s attention, describing the attempt to support the yen as standing in front of a speeding train.
The Inflation Loop: Fed Hikes and AI Skepticism
The primary concern for investors is that sustained high oil prices will revive inflation, forcing central banks to abandon hopes of interest-rate relief. Nigel Green stated, The decline that previously allowed the Fed to ease policy may already be coming back… This does not look like a temporary spike, but a real resurgence of the inflation question.
Money markets now fully price in a Federal Reserve interest-rate increase by September.
Escalating Middle East tensions have pushed crude prices higher, raising concerns that inflation could re-accelerate and delay interest-rate relief, maybe even cause the Fed to hike,
said Sameer Samana at Wells Fargo Investment Institute. We think oil prices eventually normalize, but appreciate that things may get worse before they get better.
This monetary pressure coincides with a growing “sell the news” sentiment regarding artificial intelligence. While companies like Meta, Microsoft, and Amazon signaled plans to spend as much as $725 billion on AI this year, investors are demanding evidence of earnings growth. Alphabet Inc. saw its stock fall 6.9% after raising its capital-expenditure forecast, and Tesla tumbled 15% following a weaker-than-expected profit report. These tumbles contributed to the S&P 500 falling 1.2%, its biggest one-day drop in a month, and the Nasdaq 100 losing 1.9%.
Adding to the volatility, the Trump administration on Thursday announced taxes of 10% to 12.5% on imports from 60 trading partners, accounting for 99% of U.S. imports, stating they failed to fully enforce bans on goods produced by forced labor. These stopgap levies followed a defeat for other such tariffs at the Supreme Court.
As energy prices remain unstable and the Federal Reserve monitors core inflation, the global economy faces a precarious period where geopolitical conflict in the Red Sea and the Persian Gulf directly dictates the cost of capital and the stability of equity markets.
