IEA: US-Iran escalation threatens 2027 oil surplus forecast The International Energy Agency (IEA) predicts supply will expand by 7.5 million bpd next year after a 3.7 million bpd contraction this year, but that is contingent on improved Hormuz transits. "An escalation in hostilities on 7-8 July, however, clouds the outlook and could upend the forecast that sees the market flipping to a surplus next year," it said, adding that a lasting peace agreement is a "must" for oil markets to normalise, according to Reuters. The IEA's 2027 forecasts imply that supply will outweigh demand by 4.62 million bpd next year from an 860,000 bpd deficit this year, provided producers can restart fields and refiners can resume normal product shipments.
