IEA says Hormuz closure squeezes global economy as oil demand destruction deepens

• Oil demand forecast to fall by 1.6 million barrels per day in 2026, an increase of 510,000 barrels per day from the July prediction
• Global oil supply remains 6.3 million barrels per day lower year-on-year in July due to renewed hostilities and maritime disruptions in the Strait of Hormuz
• Brent crude prices have shown extreme volatility, surpassing $100 per barrel and falling near $70 per barrel last month, currently trading just under $90

Summary: IEA Warns of Deepening Oil Demand Destruction Amid Hormuz Strait Closure

The International Energy Agency (IEA) significantly revised its 2026 oil demand forecast downward on Wednesday, projecting a decline of 1.6 million barrels per day—an increase of 510,000 barrels per day from its July estimate of approximately 1 million barrels per day.

The deeper demand destruction stems from the ongoing closure of the Strait of Hormuz, a critical global shipping chokepoint. High fuel prices continue suppressing consumption, though the IEA expects demand to recover later in the year, returning to growth in the fourth quarter of 2026.

Market Impact:

Negotiations between Washington and Tehran to reopen the strait remain unsuccessful despite signals from officials. "Renewed hostilities and maritime disruptions" are constraining global oil supply, which stood 6.3 million barrels per day lower year-over-year in July.

The supply constraints have generated significant crude price volatility. Brent crude surpassed $100 per barrel last month before falling near $70, currently trading just under $90 per barrel. Goldman Sachs analysts indicate upside risks to their Brent crude base case forecast.

Key Implications:

The combination of restricted supply through Hormuz and demand destruction from elevated prices creates a complex market dynamic. While high prices dampen consumption, the closure of this vital waterway—through which significant global oil flows typically pass—continues to support price levels and volatility.

The energy sector faces ongoing uncertainty as geopolitical tensions prevent resolution of the Hormuz situation, squeezing the global economy and complicating supply-demand dynamics for the remainder of 2026.
