Oil and gas supplies could take months to return to normal after Iran deal, energy experts say

AP News· June 21, 2026

Energy experts warn that global oil and gas supply chains may require several months to stabilize following a potential deal to end the conflict with Iran. The announcement comes as the United States and Iran prepare for high-level talks in Switzerland this Sunday, despite Tehran’s recent move to once again close the strategic Strait of Hormuz. For the Oil & Gas sector, this timeline suggests continued price volatility and logistical hurdles even as military hostilities appear to be drawing to a close.

The upcoming diplomatic talks in Switzerland represent a pivotal moment as the conflict between the United States and Iran reportedly nears its conclusion. However, the immediate outlook for energy markets remains complicated by Tehran’s recent declaration that it has once again closed the Strait of Hormuz, a critical chokepoint for global oil shipments. Energy experts emphasize that the cessation of hostilities will not provide an overnight fix for the industry, as the physical and regulatory infrastructure required to resume normal flow has been significantly disrupted during the war.

Within the United States, the end of the conflict has prompted members of Congress to question the overall strategic value and cost of the military engagement, asking if the war was worth the expenditure. This political scrutiny coincides with broader economic shifts, including a recent dip in U.S. gas prices below the $4 mark, though experts suggest this relief may be temporary if supply routes remain blocked. The transition from a wartime footing to a diplomatic resolution is expected to be a protracted process, with analysts noting that the logistical backlog will delay the return of normal supply levels to the global market.

The Oil & Gas sector faces a period of prolonged uncertainty as it navigates the technical challenges of restarting supply routes that have been blocked or diverted. While the prospect of an Iran deal offers a long-term path to increased supply, the months-long recovery timeline suggested by analysts means that inventory levels and shipping costs are unlikely to normalize in the immediate future. Market participants are now focused on the Sunday negotiations in Switzerland for any concrete signs of progress regarding the reopening of maritime passages and the stabilization of the Middle Eastern energy corridor.
