Trump's Iran Demands Hold Brent Above $88 as Hormuz Transit Stays Crimped
Only five vessels a day transit the Strait against a 14-vessel post-agreement average, keeping crude supply risks elevated as diplomatic progress stalls.
ICE Brent crude front-month was priced at $88.82 a barrel as of August 15 at 06:02 UTC, with NYMEX WTI crude front-month at $82.40, both contracts holding most of the gains posted on Monday, August 10, after US President Donald Trump made sweeping demands against Iran that cast doubt on any near-term normalisation of Strait of Hormuz shipping.6
Both contracts surged roughly 5% on August 10, WTI pushing back to the $82 level, as Trump's posts on Truth Social threatened to unravel the June memorandum of understanding that had briefly calmed oil markets, CNBC TV18 reported. The complication is that the $300 billion rehabilitation and economic development fund Iran cited as its war-damage demand is a provision Trump himself agreed to in the same MoU, signed at the G7 summit in France in June. His Truth Social post then demanded compensation from Iran for all the people Iran has killed in past conflicts — a direct reversal of that commitment.6
The effect on Hormuz traffic is concrete. Energy Aspects founder Amrita Sen said only five vessels are transiting the strait daily, against a 14-vessel daily average that shipping had recovered to after the June MoU signing.6
Five versus fourteen is a substantial deficit for a waterway handling a significant share of seaborne Gulf crude exports. The MoU's June signing had traders pricing in faster restoration of Iranian supply volumes. Those assumptions have since unwound.6
The price trajectory since late May captures how sharply expectations have moved. ICE Brent front-month was trading near $106 a barrel in late May, according to OilPrice.net data, before a potential US-Iran diplomatic breakthrough sent it below $80 for the first time since March on June 16, as CryptoBriefing reported. By June 24, TASS data showed Brent below $76 a barrel for the first time since March 2.1,2,3
Markets then staged a partial recovery, but it did not hold. On July 27, ICE Brent crude September 2026 delivery fell more than 9% on London's ICE, sliding below $88 a barrel for the first time since July 21, with TASS reporting Brent at $87.90 at 09:32 GMT. NYMEX WTI August 2026 delivery fell 7.26% to $82.83 in the same session. FX Empire attributed the move to traders pricing in a quicker-than-expected restoration of Middle East supply following the early deal stages.5,4
August 10 reversed most of those July losses. Trump's Truth Social post shifted the calculus, and both contracts surged. Brent climbed back above $88 and has held there.6
The internal contradiction in the US position is now the main overhang. Trump signed a 14-point MoU in June that included the $300 billion Iranian fund, then posted demands that directly contradict that commitment. Iran cited the same MoU to support its war-damage claim. Both parties are invoking a document they have read in incompatible ways, and neither appears close to resolving it.6
The five-vessel daily transit count at Hormuz is the most verifiable variable available. Brent fell more than $30 a barrel between late May and late June as deal optimism built; approaching the post-MoU daily average of 14 vessels would be required before traders restore those supply assumptions. The July 27 crash — a 9%-plus single-session move — showed what happens when those expectations shift fast. They can shift just as fast in reverse.5,6,1,3
