IEA Flags US-Iran July Clashes as Risk to 2026 Oil Surplus Projection

On 11 July the International Energy Agency revised its baseline after June supply rebounded 4.1 million bpd to 98.8 million bpd once tankers cleared the Strait following the June MoU. Global stocks posted their first monthly build since March, yet output remained 9.4 million bpd below pre-war averages. The agency explicitly conditions its surplus forecast on sustained de-escalation and insurance rates falling below the 3 percent of vessel value recorded after 7 July.

US sanctions enforcement and Iranian export recovery both depend on Hormuz throughput. Tehran gains revenue from resumed sales while Washington retains leverage through secondary sanctions on shippers. Either side's escalation raises insurance premia to 5 percent and immediately cuts effective export capacity, shifting the market from the documented 1.7 million bpd demand contraction in Q3 toward tighter balances.

Refinery margins have already diverged: crude cracks eased while diesel and gasoline cracks reached four-year highs, indicating product markets remain tighter than headline crude data suggest. Central banks pricing terminal rates on 2026 surplus assumptions now face direct geopolitical variance.

Absent verified de-escalation by end-August, the IEA's 3.7 million bpd 2026 supply decline trajectory will require upward revision, tightening near-term price bands and supporting higher for longer policy rates.
