US-Iran Instability Threatens Next Year's Oil Market Surplus Forecast

The partial recovery of oil shipments through the Strait of Hormuz and the first increase in global oil inventories since the conflict began have been overshadowed by escalating tensions between the United States and Iran this week, which could reverse the outlook for an oil market surplus next year, the International Energy Agency (IEA) reported on Friday.

Oil Prices Plummet Following Preliminary Agreement

Oil prices have dropped significantly since the United States and Iran signed a Memorandum of Understanding (MoU) in mid-June. The North Sea Dated crude price fell by $31 per barrel in June to $68 per barrel in early July, marking the lowest level since January and $2 per barrel below pre-war levels.

In its closely watched July Oil Market Report, the IEA stated: "However, the escalation of tensions on July 7 has clouded the outlook and could reverse the forecast for the market to move into surplus next year."

Global Oil Supply Recovery

Since the Strait of Hormuz reopened, oil tankers have been urgently leaving the Persian Gulf, including millions of barrels of Iranian crude oil that Tehran had been unable to transport due to the US blockade between mid-April and mid-June.

As a result, global oil supply has recovered strongly by 4.1 million barrels per day (bpd) to 98.8 million bpd in June, as Gulf production partially rebounded, the IEA noted.

Summary of Oil Supply Situation

Supply and Demand Outlook

However, global oil production remains approximately 9.4 million bpd below pre-war levels, with supply expected to average 3.7 million bpd lower at 102.6 million bpd in 2026, "depending on a rapid de-escalation of tensions."

Global oil demand is beginning to recover from the low seen in the second quarter, with the annual decline reducing from 4.8 million bpd in April-June to an expected annual decline of 1.7 million bpd in the third quarter, the IEA estimated.

Oil Products Market Recovery Slower

Notably, while a wave of crude oil has been able to pass through the Strait of Hormuz in recent weeks, oil product supply and delivery have recovered much more slowly, with the market remaining tight.

The IEA noted: "The divergence between the well-supplied crude oil market and the tightening oil products market has driven a sharp increase in crude oil and refining margins to four-year highs in early July."

Although concerns about jet fuel shortages have eased in recent weeks as refineries pushed production to new highs, diesel and gasoline markets have tightened further, with gasoline margins increasing sharply.

Analysis and Outlook

The escalating tensions between the US and Iran create a difficult situation for the oil market. While there are positive signs regarding the restoration of oil flows through the Strait of Hormuz and increased oil inventories, recent political tensions could quickly reverse these gains.

The IEA emphasizes that the outlook for global oil supply in 2026 still heavily depends on whether tensions between the US and Iran can be reduced quickly. Any further escalation could lead to supply shortages and push oil prices higher.

Meanwhile, global oil demand is showing signs of recovery, but this recovery is uneven across different oil products. The gasoline and diesel markets are particularly tight, indicating that the global economic recovery is uneven and may not be strong enough to drive oil demand growth rapidly.

Regional Production Impact

Strategic Implications

The current situation presents significant strategic implications for oil-importing nations and global energy security. The potential disruption of oil supplies through the Strait of Hormuz, which handles approximately one-third of global seaborne oil trade, remains a critical risk factor.

Energy security analysts suggest that consuming countries may need to consider strategic reserve releases and diversification of supply sources to mitigate potential disruptions. The ongoing situation also highlights the vulnerability of global oil markets to geopolitical tensions in key producing regions.

Conclusion

The oil market currently stands at a critical juncture. While there are positive factors such as the restoration of oil flows through the Strait of Hormuz and demand recovery, geopolitical tensions threaten to reverse these gains. The market will closely watch developments in US-Iran relations in the coming weeks, as any escalation could significantly impact oil prices and global market stability.

The IEA's assessment underscores the delicate balance of the oil market and how quickly geopolitical developments can alter supply-demand dynamics. As the world continues to navigate the complex interplay between energy markets and international relations, the oil market remains sensitive to political developments in key producing regions.
