ICE Brent Slides to $90.62 as US-Iran Pause Cuts Fed Rate Hike Odds to 36%
Two days without military strikes in the Persian Gulf have unwound much of crude's war premium, pulling CME-tracked Federal Reserve rate hike probability from 81% to 36%.
ICE Brent crude front-month eased a further 1.46% to $90.62 per barrel by early Monday (2026-07-27), extending a two-session rout that began when the United States and Iran refrained from launching military strikes in the Persian Gulf for a second consecutive day. The pause sent the September contract down 4.9% to $92.02 when trading resumed on Sunday (2026-07-26), following a 3.9% decline on Friday (2026-07-24).4,6
The scale of the retreat reflects how aggressively war premium had been priced in. ICE Brent front-month had traded around $101 per barrel on Friday (2026-07-24), roughly 42% above a multi-month low of $71 hit in early July, before ending that session at $96.78 as the first signals of de-escalation emerged.5
NYMEX WTI crude September fell 5.6% to $84.34 on Sunday (2026-07-26), after dropping 3.1% on Friday (2026-07-24). The ICE Brent October contract, now the most actively traded part of the curve, shed 4.6% to $87.48 on Sunday (2026-07-26). NYMEX WTI front-month stood at $84.25 by Monday morning (2026-07-27).4
Federal Reserve rate expectations moved with crude almost tick for tick. CME FedWatch data published around July 23 (2026-07-23) showed traders pricing an 81% probability of a September rate hike while Brent was above $100. By Sunday (2026-07-26), with crude retreating sharply, CME data showed traders assigning just a 36% probability to a hike at any upcoming meeting.3,4,6
The arithmetic connecting oil prices to rates runs through inflation. U.S. CPI rose 4.2% year-on-year in May — the first reading above 4% in three years — driven by energy costs tied to the Iran conflict, with the monthly gain from April running at 0.5%, according to data published on June 10 (2026-06-10). The Federal Reserve's preferred inflation gauge also reached 4.1% in May from a year earlier, with core prices excluding food and energy rising 3.4%.1,2
New York Federal Reserve President John Williams, speaking on July 7 (2026-07-07), said he expected falling energy prices to pull overall inflation lower in coming months and described current policy as being in a good place. His comments predated the surge during the week of July 20 (2026-07-20). With Brent now retreating, his assessment looks more achievable — provided the US-Iran pause holds.2
China's demand picture complicates any straightforward bullish recovery case for crude. Chinese government figures show daily average oil purchases fell roughly 16% from the January-February period to March-April, the months when prices had soared, indicating price-sensitive demand destruction at elevated levels.5 Cheaper oil could revive that buying, but the pace matters for how quickly the U.S. inflation overshoot fades and how aggressively the Fed needs to respond.
Gold has tracked the rate logic directly. When ICE Brent settled at $100.69 per barrel after surging 7% following attacks on Saudi oil tankers in the Red Sea, spot gold slipped 0.5% to $4,027.54 per ounce as tightening rate expectations weighed on the non-yielding metal.3 By Monday (2026-07-27), with crude lower and rate hike odds contracting, gold had recovered to $4,107.89 per ounce.
The central uncertainty now is whether the US-Iran pause holds. A resumption of strikes in the Strait of Hormuz would rapidly reconstruct the supply fear that carried Brent to $100 and pushed CME rate hike odds to 81%. If it does hold and coming inflation data confirm the May overshoot was energy-driven rather than broad-based, those odds could retreat further still from 36%. The next U.S. CPI print is the cleaner signal.4,5,1
