The next escalation in the Iran conflict is now economic: President Donald Trump threatened “tremendous economic consequences,” while Treasury Secretary Scott Bessent said the United States would impose its “toughest sanctions in history” on Monday. Washington has already targeted 115 individuals, ships, and entities accused of helping Iran evade oil sanctions, and Bessent said Iranian crude available to China could dry up over the coming month as the U.S. blockade of Iranian ports takes effect.

That makes the sanctions announcement a direct oil-market catalyst. WTI was near $87 a barrel and Brent near $94, with further upside risk if Iranian exports are disrupted. China’s Foreign Ministry rejected unilateral sanctions without U.N. authorization, complicating enforcement and pointing to a wider split in energy and financial channels. Tehran’s insistence that negotiations must proceed from a position of strength leaves little evidence that the pressure campaign will resolve quickly. The broader backdrop is already deteriorating: Russia struck Kyiv again amid Patriot shortages, while North Korean missile launches and renewed Israeli strikes in southern Lebanon add to the geopolitical risk premium.

The Treasury market is increasingly trading fiscal and geopolitical risk rather than a simple growth narrative. The 10-year yield was around 4.71%, the 2-year near 4.20%, and the 30-year above 5.25%, its highest level since 2007. The United States also crossed $40 trillion in national debt, while the July budget deficit reached its highest level since March 2021. Treasury’s plan to expand buybacks of longer-dated bonds is an attempt to support a market under pressure, but it also highlights the difficulty of absorbing growing issuance.

Against that backdrop, the Federal Reserve has held rates at 4.25%–4.50% despite President Trump’s calls for cuts. Real GDP rebounded to a 3% annualized pace in the second quarter from a 0.5% contraction in the first, while futures imply roughly a 35% chance of a September hike. Fed Chair Kevin Warsh’s Jackson Hole keynote therefore carries unusually high information value: markets need guidance on policy and on possible institutional reform as inflation, fiscal supply, and war-related energy risks pull in different directions. The euro area is facing a similar hawkish repricing, with sticky inflation and energy shocks lifting expectations for a possible September ECB hike.

Google’s agreement with Marvell is the clearest technology-market development: the companies will deepen work on custom silicon tied to Google’s TPU ecosystem, spanning inference accelerators, storage and networking controllers, memory interfaces, and near-memory compute. Google granted Marvell roughly $12.2 billion in stock options, sending Marvell shares sharply higher and pushing Broadcom lower as investors reassessed who will supply Google’s AI chips.

The deal matters beyond the immediate equity reaction. It reinforces the shift from reliance on general-purpose processors toward customer-specific accelerators designed alongside the software stack, potentially redistributing value across the semiconductor supply chain. Nvidia is pursuing a parallel strategy through a technology, investment, and talent arrangement with coding startup Poolside rather than a formal acquisition. Jensen Huang’s meeting with Rebellions CEO Sunghyun Park likewise points to continued efforts to broaden Nvidia’s relationships across global AI-chip developers. The competitive question is no longer only demand for AI compute, but which hardware architectures and partnerships capture that spending.
