What does the IEA say about how the recent U.S.-Iran escalation on 7–8 July affects its 2027 oil market surplus forecast?

The IEA states that 'an escalation in hostilities on 7–8 July... clouds the outlook and could upend the forecast that sees the market flipping to a surplus next year.' This directly links the renewed tensions to heightened uncertainty over whether the anticipated 2027 oil market surplus will materialize, as the forecast is explicitly described as contingent on stable conditions—particularly improved transits through the Strait of Hormuz.

How did the reopening of the Strait of Hormuz in June affect global oil supply, and what was the gap relative to pre-war levels?

The reopening of the Strait of Hormuz in June facilitated a rise in global oil supply of 4.1 million barrels per day (bpd), but supply remained 9.4 million bpd below pre-war levels; the IEA notes this shortfall occurred despite the Strait’s reopening, underscoring that full recovery had not yet been achieved, and that the prior effective closure had removed up to 14 million bpd of crude flows—the largest oil supply crisis in history.

The International Energy Agency warns that escalating U.S.-Iran hostilities could disrupt its forecast of a 2027 oil market surplus. Global supply rose in June but remains significantly below pre-war levels, contingent on improved Strait of Hormuz transits.
