IEA warns Hormuz Strait crisis could push global oil markets into a ‘red zone’, draining emergency reserves and driving up fuel prices worldwide.

IEA Executive Director Fatih Birol said the single most important solution to the Iran war energy shock is the unconditional reopening of the Strait of Hormuz.

While a surplus of oil in the market before the war has helped absorb the energy shock it caused, "stocks are eroding", said Fatih Birol.
