The U.S.-Iran confrontation over the Strait of Hormuz remained the dominant geopolitical market risk, with tanker traffic disrupted and Brent crude holding around $88.5-$88.9 a barrel. President Donald Trump said the United States would take the strait if it defeated Iran, while Iranian Maj. Gen. Amir Hatami issued a warning in response. The immediate market consequence is less a supply shock than a persistent risk premium, with higher oil feeding directly into inflation expectations and long-end Treasury yields.

Washington also signaled a shift in its broader regional posture: Trump ordered the Pentagon to substantially reduce joint military exercises with South Korea, including the Ulchi Freedom Shield drills scheduled for August 17-27. Separately, Jared Kushner and Nickolay Mladenov met Egyptian, Qatari and Turkish mediators in Cairo over Trump's Gaza roadmap, with Hamas officials present at some sessions. The parallel diplomacy offers a potential offset, but the oil channel remains the clearer macro transmission mechanism.

AI capital formation accelerated into headline territory. Bloomberg-reported coverage said Stripe was nearing a deal to acquire OpenRouter for more than $7 billion, highlighting the strategic value of model-routing and AI infrastructure tools beyond the model developers themselves. Anthropic, meanwhile, was reported to be preparing for a possible IPO at an implied valuation above $1 trillion, after a financing round valued the company at $965 billion and confidential S-1 and bank-meeting activity reportedly began.

The funding wave is also spreading into the physical bottlenecks around AI. Form Energy, Base Power and Valar Atomics were cited as raising $750 million, $1 billion and $1 billion, respectively, while defense-AI company Helsing raised $1.8 billion. IBM and OpenAI formed a joint enterprise-delivery partnership, and China’s DeepSeek planned steep API price increases effective August 17. Together, the developments point to a market competing on distribution, energy and monetization—not just model performance.

Risk assets remained resilient even as the energy and rates backdrop deteriorated. The S&P 500 was roughly flat to slightly lower around 7,751-7,786, while the Nikkei 225 rose about 0.59% and the KOSPI gained about 2.42%; European equities were softer. U.S. index futures were modestly positive in a late-Sunday update, and the VIX remained in the mid-teens, indicating that investors had not repriced the geopolitical risk as a broad equity shock.

Rates told a less forgiving story. The 10-year Treasury yield held around 4.69%-4.70%, with longer maturities also elevated as oil threatened to keep inflation sticky. Gold remained bid between $4,370 and $4,460, while the dollar was mixed and the yen stayed sensitive to intervention concerns. Markets were also carrying forward July CPI of 0.1% month over month and 3.4% year over year, core CPI of 2.5%, and a 9-3 FOMC hold at 3.50%-3.75%, including three votes for a hike. Japan’s Q2 GDP expanded 0.3% quarter over quarter, adding a modest regional growth positive.
