Brent Eases From $90 Peak as US-Iran Attacks Keep Hormuz Risk Premium Elevated
ICE Brent front-month slipped to $88.88 on Monday after surging past $90 last week, as US and Iranian forces extended strikes threatening the Strait of Hormuz.
ICE Brent crude front-month was trading at $88.88 a barrel on Monday (2026-07-20), easing fractionally from the $90.79 peak reached the prior Monday (2026-07-13), when US and Iranian forces expanded attacks that have curbed energy shipments through the Strait of Hormuz. NYMEX WTI front-month was at $82.42, off its comparable high of $84.68 from the same session. The retreat is limited against the scale of recent gains.7
ICE Brent gained 15.9% in the week ending Friday (2026-07-11), its largest weekly advance since April, after a sequence of strikes on Iranian military sites drove fears of physical supply disruption at the strait. WTI front-month rose 15.5% over the same period, its largest weekly ascent since early March. Both benchmarks have recovered a substantial portion of the nearly 30% they shed in the months before the conflict escalated.7
The Strait of Hormuz handles approximately 20% of global oil supply, making it the single most consequential transit point in commodity markets. Iran has signaled it could move to restrict or close the waterway in response to US military pressure. Any sustained interference would force tankers onto longer routes around the Arabian Peninsula, adding days to voyage times and reducing near-term available supply.6
Crude oil prices jumped as much as 9% in a single session after US President Donald Trump announced plans to impose shipping fees in the Strait of Hormuz, adding a policy dimension to the physical risk already embedded in the conflict.3 Washington also revoked sanctions waivers on Iranian oil exports, reducing Tehran's ability to monetise crude and raising the cost of any diplomatic retreat.5
Fresh US strikes on Iranian military sites on Thursday (2026-07-09) extended a run of four consecutive sessions of gains. ICE Brent reached $85.28 a barrel that day, following a 12% surge over the preceding three sessions, with WTI at $80.02.4
Traders noted the escalation arrived just weeks after Washington and Tehran had signed an interim memorandum of understanding aimed at halting hostilities. The effective suspension of that arrangement has removed what many assumed was a diplomatic floor under tensions, leaving the market without a credible de-escalation path in the near term.2
The geopolitical risk premium in Brent is visible in adjacent markets. ICE Endex TTF front-month was up 2.34% on Monday (2026-07-20), reaching €58.85 per MWh. The TTF move reflects partly independent European gas supply dynamics, but a sustained Hormuz disruption would redirect LNG cargoes away from Asia toward Europe via the Atlantic arbitrage, compressing available volumes for both regions. JKM Asian LNG front-month was steady at $21.02 per MMBtu on Monday (2026-07-20), suggesting markets have not yet priced a full Hormuz closure into Asian spot supply.6
Positioning data are not reported in the source material. The consensus across eight bullish signals points uniformly in one direction, but recent experience argues for naming the risks that would invalidate it. The most plausible bearish scenario involves a negotiated agreement, possibly a reconstituted version of the MoU that collapsed, that reopens Hormuz without physical damage to its infrastructure. A ceasefire before Washington and Tehran exchange further strikes could unwind a significant portion of the risk premium rapidly.2
WTI crude settled at $97.91 a barrel on Thursday (2026-05-14) during the week the conflict first drove prices toward a monthly peak, with futures trading across a range of $92.84 to $99.09 as the market reacted to the widening hostilities. Prices have consolidated well below those levels since. Whether physical tightness, measured in actual tanker diversions and reduced loadings rather than threat perceptions, materialises to justify current levels is the central test. Actual shipping data from the strait in the coming days will be the most direct read on whether the risk premium rests on volumes or sentiment.1
