The International Energy Agency issued a stark warning on Friday that renewed fighting between the United States and Iran threatens to extend the global energy crisis. The United Nations agency flagged the risk that resuming hostilities could derail hopes of a swift recovery in energy markets, even as a lull in action appeared to create space for diplomatic efforts. The warning comes at a critical moment when world oil demand tracks toward its first annual decline since 2020, as the conflict continues to disrupt production and exports across the Middle East.

Sources suggest that a ceasefire could be revived amid the current pause in fighting and backroom diplomacy. However, officials cautioned that the US military remains ready to resume attacks if necessary. The latest round of fighting this week erupted from rival interpretations of provisions governing the Strait of Hormuz in the memorandum of understanding between the two nations. Before the conflict began in April with US and Israeli strikes on Iran, the waterway carried roughly a fifth of the world’s oil and liquefied natural gas exports.

The IEA reported that the effective closure of Hormuz cut as much as 14 million barrels per day of crude oil flows. The fuel shortage and resulting price increases have hammered the global economy hard, creating ripple effects across industries and nations dependent on stable energy supplies. The agency stated that the recovery was underway thanks to last month’s US-Iran memorandum of understanding, but warned that renewed escalation could further complicate the outlook.

Shipping Through Critical Waterway Halts Again

Following the agreed memorandum of understanding and reopening of the strait, global oil supply rose by 4.1 million barrels per day in June, the IEA reported in its latest monthly oil market report. However, supply remained 9.4 million barrels per day below pre-war levels, underscoring the persistent impact of the conflict. The agency noted that Gulf production lifted during this period, although output stayed well below pre-war benchmarks because of lingering security disruptions throughout the region.

The report revealed that oil supply from Gulf producers rose by around 3.5 million barrels per day during June after output partially recovered following the framework agreement between the United States and Iran. However, intermittent disruptions to shipping through the Strait of Hormuz persisted because of security concerns and continued reliance on US naval escorts. This left regional oil production approximately 11.4 million barrels per day below pre-war levels, demonstrating the profound impact of ongoing instability.

With fighting resuming, shipping through the strait has once more ground to a halt. Despite the disruption, oil prices held broadly steady in early Friday trading. Brent crude stood at $76.37 a barrel, little changed from Thursday’s close, though up more than $4 from earlier in the week. Market analysts suggest that traders may be anticipating another diplomatic breakthrough or hedging against further volatility.

OPEC+ Production Shows Recovery Signs

Production from the OPEC+ group, comprising the Organization of the Petroleum Exporting Countries and its allies, increased by around 2.45 million barrels per day in June to 38.39 million barrels per day. Saudi Arabia accounted for roughly 900,000 barrels per day of the increase, while Kuwait contributed around 630,000 barrels per day. These figures demonstrate the capacity of major producers to ramp up output when security conditions allow.

Output from non-OPEC+ producers rose by around 1.63 million barrels per day to 60.37 million barrels per day. The United Arab Emirates accounted for more than half of this increase at approximately 940,000 barrels per day, highlighting the nation’s critical role in global energy markets. The UAE’s ability to boost production reflects both its substantial capacity and relatively stable security environment compared to other regional producers.

Supply Forecast Revised Higher Despite Lingering Risks

The IEA announced that global oil supply is expected to average 102.6 million barrels per day this year if transit volumes through the Strait of Hormuz continue to recover. The forecast was revised upward from last month’s estimate, reflecting cautious optimism about the diplomatic process and partial restoration of shipping lanes. However, this projection still implies a significant year-on-year decline, demonstrating the conflict’s lasting impact on global energy markets.

The agency emphasized that significant risks remain. Negotiations over the future administration of the Strait of Hormuz continue, and regional attacks have not fully ceased. These ongoing security challenges create uncertainty for shippers, insurers, and energy companies attempting to plan operations in the volatile region. Despite improving conditions after the US-Iran framework agreement, geopolitical risks in the Gulf still pose a threat to the market outlook, the IEA cautioned.

Global oil production is projected to rebound to 110.1 million barrels per day in 2027, according to the agency’s projections. This forecast assumes that security conditions improve substantially and the critical waterway returns to more normal operations over the coming months and years. Energy analysts note that achieving this recovery depends heavily on sustained diplomatic progress and the absence of major new escalations between regional powers.

Market Outlook Remains Clouded by Uncertainty

The IEA’s latest assessment paints a picture of tentative recovery threatened by persistent instability. While June’s production increases offered hope that the worst disruptions might ease, the swift return to conflict demonstrates how fragile the situation remains. Energy companies face difficult decisions about investment and operations in a region where conditions can deteriorate rapidly, and shipping routes can close with little warning.

World oil demand tracking toward its first annual decline since the pandemic year of 2020 reflects broader economic impacts of the prolonged energy crisis. High fuel costs have constrained consumer spending, increased transportation expenses, and contributed to inflationary pressures across major economies. Industrial sectors dependent on reliable, affordable energy supplies have faced production challenges and increased operating costs that ripple through supply chains.

The memorandum of understanding between the United States and Iran had raised hopes for a sustained de-escalation that would allow energy markets to stabilize. The swift breakdown of that agreement over interpretations of Strait of Hormuz provisions underscores the complexity of achieving lasting peace in the region. Diplomatic sources suggest that both sides retain interest in avoiding a full-scale war, but competing interests and mutual mistrust continue to fuel cycles of escalation and tentative compromise.

As the situation develops, energy market participants watch closely for signs of either renewed diplomatic progress or further military action. The IEA’s warning serves as a reminder that global energy security remains deeply vulnerable to regional conflicts, particularly those affecting critical chokepoints like the Strait of Hormuz. The coming weeks will prove crucial in determining whether diplomatic efforts can revive the ceasefire or whether renewed fighting will plunge energy markets into deeper crisis.
