IEA Cuts 2027 Oil Supply Forecast on Iran-Related Constraints

The significance here is less the size of the revision — which the IEA left unspecified — than the source of the constraint: geopolitics now shapes the medium-term supply picture, not just near-term volatility. That matters for anyone using agency forecasts as a planning baseline, though the missing magnitude makes the adjustment hard to weigh. The open question is whether subsequent reports quantify the Iran-related gap and whether other supply-side risks get folded into the same outlook.
