Aug 31 – Sep 6

The U.S.–Iran confrontation moved into a materially more dangerous phase as U.S. forces destroyed three Iranian crude oil tankers near the Strait of Hormuz on September 5. Iran said it had launched ballistic missiles at a U.S. aircraft carrier and destroyer, while warning that continued attacks could trigger efforts to block Gulf oil exports. The exchange turns a regional conflict into a direct threat to one of the world’s most important energy corridors.

Oil markets reacted immediately. International benchmarks rose more than $4 a barrel on September 1 to a five-week high, with sanctions, shipping restrictions and insurance costs adding to the supply-risk premium. Iran subsequently expanded the list of vessels it considered non-compliant and vulnerable to fines, confiscation or detention. OPEC+ was expected to leave October output policy unchanged, preserving formal supply stability but doing little to remove the security premium.

The market implication extends beyond crude. Higher energy costs complicate an already sticky inflation picture, while European natural-gas prices reached a three-year high ahead of winter. Oil-linked emerging-market credits remained relatively resilient even as higher core yields pressured longer-duration debt. With Washington signaling additional sanctions and Tehran threatening more severe retaliation, the coming week’s key question is whether transit disruption remains a threat or becomes an operational reality.

The Federal Reserve outlook swung sharply as investors tried to reconcile a deteriorating labor-market trend with unexpectedly firm growth and inflation. Payrolls in the latest report rose only 56,000, while the prior month was revised to a 23,000 decline and revisions to May and June removed another 103,000 jobs. Yet the August payrolls figure cited in market coverage came in near 162,000, roughly triple consensus, pushing the implied probability of a September 15–16 hike back above 60% after it had fallen toward 50–50.

The underlying tension is visible across the data. July CPI was 3.4% year over year, core PCE was 3.3%, and the Beige Book described moderate price increases with only slight employment growth. At the same time, the S&P Global U.S. flash composite PMI rose to 56.0 from 54.5, its fastest pace since April 2022, pointing to annualized third-quarter growth near 3%.

Treasuries captured the whipsaw: the 10-year yield fell toward 4.74–4.76% when Christopher Waller said he could support holding rates if inflation eased, then briefly reached about 4.82% after the stronger payrolls reading. The dollar softened and equities advanced despite the reversal, suggesting investors still view resilient growth as supportive. That leaves the Fed facing a narrow path: weak labor momentum argues for patience, but demand and inflation make a September cut increasingly difficult to justify.

AI investment widened decisively beyond semiconductors into the physical systems required to operate increasingly large models. Broadcom reported third-quarter AI semiconductor revenue of $16.7 billion, up 221% year over year, and guided fourth-quarter AI semiconductor revenue to $21.7 billion. Its longer-range outlook—about $115 billion in AI semiconductor revenue for fiscal 2027 and roughly $230 billion for 2028—shows how aggressively suppliers are underwriting continued hyperscaler spending.

The more consequential development was the financing of everything around the chip. Flex agreed to buy EPC Power for $4.4 billion, adding power-conversion equipment for data centers. SoftBank-backed SB Energy filed for a U.S. IPO with 8.8 gigawatts of data-center capacity contracted or under construction and 5.5 gigawatts of associated power projects. TCS subsidiary HyperVault secured 264 acres in Hyderabad for a campus capable of reaching one gigawatt, while Blue Owl moved toward a data-center REIT and public listing.

The funding race is also moving upstream: Nscale sought $3.5 billion after a $45 billion Anthropic deal, Gimlet Labs raised $300 million at a $3 billion valuation, and Thinking Machines Lab discussed a $5 billion–$6 billion round at a $40 billion pre-money valuation. Model launches from OpenAI and Anthropic supplied the narrative catalyst, but the investment signal is broader. AI is becoming a full-stack infrastructure trade, with power availability and capital-market access increasingly as important as accelerator supply.

Russia and Ukraine took limited steps toward de-escalation as U.S. envoys pursued talks in Moscow and Kyiv, but the week produced no nationwide ceasefire or political settlement. Vladimir Putin ordered a three-day halt to Russian strikes against Kyiv beginning September 5, explicitly linking the pause to preparations for discussions with Steve Witkoff and Jared Kushner. Volodymyr Zelenskyy said Ukraine would reciprocate by suspending long-range attacks on Moscow and other Russian cities during the same period.

Kyiv also proposed a broader frontline ceasefire running through September 8 and issued orders to several brigades to halt offensive operations. Russia rejected that wider arrangement, limiting its commitment to the pause on strikes against Kyiv while attacks elsewhere continued. Zelenskyy used the diplomatic opening to emphasize that Ukraine needed credible security guarantees, making the terms of any eventual settlement at least as important as the temporary reduction in long-range attacks.

The episode matters because it establishes a channel for U.S.-brokered engagement without yet changing the military balance. A short pause can facilitate travel and negotiations, but its narrow scope leaves the main battlefield active and the risk of rapid breakdown high. The next test is whether the envoys can convert a tactical pause into agreement on a broader ceasefire framework rather than another isolated suspension of strikes.
