World absorbs Iran oil loss, but depleted stocks raise risks

• The supply disruption peaked at 14 million barrels per day, but was managed through record storage releases (approximately 1 billion barrels globally, including 400 million via IEA coordination), increased Saudi/UAE exports, and reduced Chinese demand due to EV adoption.
• Global oil inventories were drawn down at record pace, draining the buffers designed to protect against supply crises; replenishing these reserves at current prices would cost over $70 billion.
• Despite a preliminary peace deal, energy infrastructure damage will take years to fully repair, and the 60-day ceasefire remains fragile with key issues like Iran's nuclear programme unresolved, leaving markets exposed to volatility without adequate reserve cushions.

Market Summary: Global Oil Markets Navigate Iran Supply Disruption

Key Developments:

The global oil market has absorbed over 1 billion barrels of supply loss following Iran's February 28, 2026 throttling of the Strait of Hormuz in response to U.S. and Israeli attacks. Despite creating the worst oil supply disruption in history—peaking at 14 million barrels per day—fears of catastrophic fuel shortages never materialized.

Price Action:

Brent crude peaked at $126/barrel in April but has since fallen below pre-conflict levels, remaining $20 below the 2008 record. Markets now price in expectations of rapid supply normalization following last month's preliminary peace agreement and 60-day ceasefire.

Supply Response:

Three factors prevented worst-case scenarios: Saudi Arabia and UAE rerouted exports, China reduced oil purchases leveraging its massive 1.4 billion barrel reserves (exceeding all 32 IEA member nations' combined 1.2 billion barrels), and the IEA coordinated release of 400 million barrels from global reserves.

Market Risks:

Critical vulnerabilities remain as global inventories have been depleted at record pace, eliminating the buffer against future disruptions. Damaged energy infrastructure in Saudi Arabia, Kuwait, Qatar, Iraq, and Bahrain will take years to fully repair. Tanker tracking data suggests slower recovery than prices indicate.

Economic Impact:

Replenishing depleted reserves will cost approximately $70 billion at current prices. Every $5 oil price increase adds $190 billion in annual global economic costs. The ECB has revised 2027-2028 price forecasts from $63-64/barrel to $65-75/barrel.

Outlook:

With peace negotiations progressing slowly and nuclear program issues unresolved, analysts warn markets may be underestimating disruption risks. The world operates without its safety net while Iran could continue disrupting Strait of Hormuz flows.
