IEA Flags 2027 Oil Glut After US-Iran Pact Sets Hormuz Re-Opening

Boom-bust swings after geopolitical disruptions are hardly new: in 1991, Kuwait’s post-war restart sent prices from $40 to <$20 within eight months, while the 1986 Saudi ‘open-tap’ strategy crashed crude 67 %. Today’s projected glut sits at the intersection of three structural forces: (1) Gulf producers hedging against long-term demand erosion from EVs by monetising reserves quickly; (2) fragmentation of traditional quota systems—UAE’s OPEC exit echoes the 1973 abandonment of prorationing in Texas; (3) the IEA’s own history of over- and under-estimating demand, reminding us that forecasts are political as much as technical. If the peace holds, the 2026-27 flood could accelerate the century-long shift away from oil by eroding producer revenues and spurring importers to refill strategic stocks rather than expand consumption. Yet the scenario rests on fragile diplomacy and assumes no new shocks—history shows chokepoints like Hormuz have been flashpoints since Britain’s 1903 Abadan concession. On a 100-year timeline, this moment may mark not just another cycle but the beginning of oil’s final phase of price-competitive abundance before structural decline.
