Brent Crude reached $109.30 on Saturday 16 May, up $3.30 from the post-summit close of $106.00 on Thursday 14 May and above the $107.77 ceiling registered on Tuesday 12 May 1. The benchmark has reversed every Trump-Xi summit-optimism correction since the verbal outputs of last week. UK forecourts now translate the wholesale move into roughly £1.75 to £1.85 per litre at the pump.
The White House presidential-actions index recorded zero Iran instruments through Day 78 , and the War Powers Act timer Murkowski has cited stood at Day 78 of 60 in arrears . Aramco CEO Amin Nasser warned on Tuesday 12 May that global oil normalisation slips to 2027 if the blockade extends past mid-June . The IEA May report showed a 246-million-barrel inventory draw in eight weeks, the largest sustained drawdown since the 1979 oil crisis.
The physical Iranian crude premium collapsed from over $30 per barrel above Brent in early April to near-parity by mid-May 2, an effective $30 unwind in six weeks. Dark-fleet logistics absorbed Iranian supply faster than Western analysts modelled. Brent is now pricing residual escalation risk, not actual supply loss; the underlying barrels still reach refineries through the bilateral channel codified by Tehran.
Counter-perspective: a sustained Brent rally without a corresponding physical-market squeeze is the classic profile of a paper-market dislocation that mean-reverts when the next round of summit diplomacy delivers verbal de-escalation. The 1973 and 2008 precedents both show benchmark spreads above $20 sustained for under 90 days before retracing. The blockade itself reaches Day 78 on Saturday 16 May , making the next four weeks the empirical test of whether this episode breaks that pattern.
