FRANKFURT, Germany — The tentative agreement to end hostilities in Iran and reopen the Strait of Hormuz marks a potentially significant development for the global energy market, although the restoration of normal oil flows is expected to take considerable time. The Strait of Hormuz, a strategic chokepoint through which nearly a fifth of the world’s crude oil passed before the conflict, has been effectively closed, disrupting supply chains and driving up prices.

On Monday, oil prices fell in response to news of the deal, which is scheduled for formal signing on Friday. However, traders and analysts caution that the resumption of steady oil exports will not be immediate, as multiple logistical and safety concerns remain. Hundreds of tankers trapped in the Persian Gulf will require time to transit through the narrow strait, and Gulf producers — including Saudi Arabia, Iraq, Bahrain, the United Arab Emirates, Kuwait, and Oman — will need to gradually ramp up output after having scaled back production during the conflict.

Shipping companies and insurers may also approach the reopening with caution. Mariners will need to assess whether security risks have genuinely abated, given the recent history of attacks linked to Iran in the region. Analysts warn that any perceived residual threat could slow the pace at which vessels resume their traditional routes.

Even with unrestricted passage, the physical constraints of maritime travel will delay the full revival of exports. For example, round-trip journeys to major Asian consumers such as Japan can span 45 to 50 days, meaning it will take weeks before crude reaches key markets in substantial quantities. The broader implications for inflation and energy supply worldwide will depend on how quickly production and shipping normalize, a process that could extend over months if the arrangement holds firm.

Details of the agreement have not been publicly disclosed, leaving uncertainties about the durability and enforcement of the truce. Market watchers will be closely monitoring developments to gauge the long-term impact on global oil flows and prices.
