WTI Crude Settles at $86.45 After Trump Reverses Kharg Island Threat and Cites Iran Talks

WTI crude settled at $86.45 per barrel Thursday on the CME, declining 3.98% from the prior session, as President Donald Trump cancelled planned strikes on Iran and withdrew a threat to seize Kharg Island. ICE Brent settled at $89.43 per barrel, down $3.67 or 3.94% on the day, per OilPrice.com data. Thursday's combined crude sell-off erased most of Wednesday's gains, which had been driven by the eighth consecutive US inventory draw reported by the EIA.

Trump's Kharg Threat and Rapid Reversal

Trump posted on Truth Social Thursday morning that the United States would hit Iran "VERY HARD" that night and would seize Kharg Island "in the not too distant future." He explicitly framed the planned seizure as equivalent to US actions in Venezuela, where Washington assumed control of export infrastructure earlier this year. Within hours, Trump reversed course, stating that diplomatic discussions with Tehran were progressing and cancelling the planned strikes.

The reversal amplified Thursday's market reaction and created an unusual intraday price arc. WTI reached an intraday high of $91.54 per barrel on the initial Kharg threat before falling to a session low of $86.00, a $5.54 per barrel intraday range. Settlement at $86.45 placed the close near the day's low, confirming that traders fully priced in the cancellation by session end.

What Kharg Island Controls

Kharg Island, located in Iran's northern Persian Gulf, serves as the terminal for approximately 90% of Iran's crude oil exports. The island, about 8 kilometres long and 4 to 5 kilometres wide, hosts storage tanks, pipelines, and offshore loading terminals that channel crude from Iran's major oil fields to tankers. China and other Asian buyers receive the majority of that oil, making Kharg central to Iran's foreign exchange revenues.

At Thursday's WTI settlement of $86.45 per barrel, each barrel flowing through Kharg generates roughly 25% less revenue than at the March 2026 conflict-era peak above $116 per barrel. The IRGC's closure of the Strait of Hormuz since late February 2026 has already reduced actual Iranian tanker movements to near zero, as commercial insurance was cancelled from March 5. A US seizure of the island would target Iran's export infrastructure itself, a distinct and more permanent form of disruption than the current shipping blockade.

Benchmarks and Brent-WTI Spread

Thursday's Brent-WTI spread settled at $2.98 per barrel, with Brent at $89.43 and WTI at $86.45. The spread has stayed relatively narrow through the Hormuz crisis, as buyers who can access both benchmarks face similar geopolitical uncertainty. WCS, the heavy crude benchmark for Alberta oil sands, carried a discount near $16 per barrel below WTI in Hardisty trading, per AER pricing data, placing the WCS price near $70.45 per barrel at Thursday's WTI settlement.

Supply Fundamentals and the Risk Premium

US crude production reached approximately 13.6 million barrels per day in recent EIA data, the highest rate on record. Record domestic output and drawdowns from Chinese strategic reserves have pushed WTI roughly 25% below its conflict-era high of $116 per barrel reached in March 2026. Thursday's session showed how quickly the remaining geopolitical risk premium can collapse on a single diplomatic signal.

Goldman Sachs maintained a Q4 2026 Brent price fork at $90 per barrel if Hormuz reopens and $115 per barrel if the closure persists through year-end, as Oil Authority reported in Wednesday's Devon Energy coverage. OPEC's June Monthly Oil Market Report, released Wednesday, cut 2026 global demand growth to 970,000 barrels per day, reflecting weaker industrial activity in Asia despite the supply disruptions. Those two diverging signals leave the market sensitive to any diplomatic breakthrough or breakdown in Iran ceasefire talks.

Oil Authority's prior coverage of the IRGC's Hormuz closure, which sent Brent above $93 per barrel, established the baseline from which Thursday's reversal must be measured. Brent's Thursday settlement at $89.43 stands $3.57 below that prior session's level, quantifying the risk premium that unwound on the cancellation news. Thursday's WTI settlement of $86.45 marks the lowest CME close since early April 2026, before the conflict reached its current escalation phase.
