What matters before the open

The Fed hiked unanimously with a higher neutral-rate dot and dealers added an October hike; GPU and memory prices kept climbing; power and siting are gating AI capacity additions; and record diesel is still feeding through as Saudi supply partially returns.

Main narratives

day change
01

The Fed hiked unanimously and left the door open to more, and sell-side desks are adding an October increase

The FOMC hiked 25bp unanimously, its first increase in three years, with 16 of 18 officials projecting at least one more move this year and the median neutral-rate dot rising to 3.25%. Only one policymaker now sees the long-run rate below 3%. Goldman added an October hike; former St. Louis Fed President James Bullard expects one more, in December, and calls three more too high.

02

GPU rental and memory prices keep rising faster than depreciation and margin assumptions, with the spread accruing to the pricing side

Nebius raised on-demand GPU rates 17-21% for October 1, a second increase in four months. Oracle says the GPUs that came up for renewal in Q1 were renewed or resold at a 20% premium. Intel's CEO puts memory price increases at five to seven times and says next year is worse; Korean suppliers hold under ten days of finished DRAM; Serenity projects cumulative 2026 legacy-memory increases of 406-575%. Apple faces an incremental 2.8-point gross-margin hit.

03

Power and siting, not chips, are gating AI capacity additions, and who pays for the grid is now a direct cost

Generac agreed to supply up to $8bn of generators for Amazon data centers, with $2.4bn of initial deliveries in 2027-2028 and a warrant for up to 1.69m shares at $200.93; the stock rose as much as 45% after hours. The House passed a bill shifting grid-upgrade costs onto data centers, a Virginia county advanced a 12-month review pause, and Gerstner sees about 25GW against a 43GW forecast.

04

Saudi supply is partially returning, but record distillate prices are still passing through into freight and food

Saudi Arabia aims to restore about half of the East-West pipeline's capacity within days and full capacity in roughly six weeks. Kpler's Matt Smith says a month offline would remove 100-120m barrels, Russia's diesel export ban is tightening products, and record $6.40 diesel is lifting grocery costs. Goldman rotated its refining call from diesel to gasoline; J.B. Hunt warned and fell 13%.

Tactical Treasuries, not strategic duration

Schroders' Remi Olu-Pitan calls the Treasury rally extremely tactical, driven by short positioning and restored clarity, and says she is not ready to embrace government bonds aggressively at these yields, seeing yields march higher if US growth stays strong.

Small caps and consumer-facing equities

State Street's Marija Veitmane flags small caps and consumer-facing stocks as most exposed to higher rates and inflation, citing margin squeeze and a K-shaped economy where middle-income consumers cannot pass on input costs.
