EIA Sees Oil Prices Easing in 2027, but Hormuz Disruption Leaves 600,000 b/d Offline

Alternative routes can absorb only part of the lost traffic. Routes involving the Red Sea, Suez Canal, or SUMED pipeline are longer, more expensive, and limited by available capacity. That makes the market sensitive not only to how much oil is produced, but also to whether it can be safely transported to buyers.

Inventories are absorbing the shock—but remain vulnerable

Reduced shipments through Hormuz are expected to cause additional global inventory draws in the coming months. The EIA forecasts U.S. commercial crude inventories will remain below the 2021–25 five-year low through the end of 2026, with domestic refinery demand, stronger crude exports, and lower imports contributing to the pressure on stocks.

The IEA’s August assessment shows how quickly the wider inventory buffer has deteriorated. Measurable global oil inventories fell by 69 million barrels in July and stood about 410 million barrels below their level at the start of the conflict.

That decline does not automatically mean the world will run out of oil. Strategic reserves, alternative suppliers, lower consumption, and rerouted cargoes can cushion the disruption. But thinner inventories leave less room for another shipping interruption, production outage, or escalation around a major export route.

Most Middle East production may return in early 2027—but not all of it

The EIA expects most crude production in the region to return close to pre-conflict averages in early 2027. It nevertheless estimates that about 600,000 barrels per day of Middle East production will remain disrupted through the end of 2027.

This distinction matters. A reopening of key shipping routes could restore much of the market’s lost volume, but producers may not be able to restart every field or export system immediately. Security risks, damaged infrastructure, disrupted logistics, and the difficulty of coordinating a full production restart can leave a residual supply gap even after trade patterns improve.

The EIA’s forecast assumes Hormuz flows begin recovering gradually rather than returning to normal immediately. That helps explain why prices can fall in 2027 while the market still carries a measurable regional disruption.

The IEA presents a more severe annual supply picture

The International Energy Agency’s August Oil Market Report adds a harsher view of the 2026 balance. It forecasts global oil supply will decline by 4.3 million barrels per day in 2026, to 102 million barrels per day. Growth of 1.4 million barrels per day from the Americas offsets only part of the losses in the Middle East and Russia.

The IEA also expects global oil demand to fall by about 1.56 million barrels per day, to 103.29 million barrels per day, as high prices and restricted availability weaken consumption.

Even with that demand destruction, the agency sees a substantial shortfall: about 1.8 million barrels per day in the current quarter. The IEA has also reported that cumulative Middle East supply losses exceeded 1.3 billion barrels, while average Hormuz flows in March through May fell to 2.7 million barrels per day, from roughly 20 million barrels per day before the conflict.

The EIA and IEA are not necessarily making contradictory claims. The EIA’s outlook emphasizes the expected path of prices, production recovery, and inventories under its stated assumptions. The IEA’s report places more emphasis on the depth of the current supply deficit and the sharp reduction in annual supply. Their forecasts reflect different models, publication timing, and assumptions about how quickly shipping and production recover.

The IEA also reported that regional exports—including cargoes using routes that bypass Hormuz—fell by 2.1 million barrels per day in July, to an average of 15 million barrels per day.

The available evidence does not support adding a precise IEA refinery-throughput forecast or a specific U.S. diesel-inventory figure to this comparison. Those figures should not be treated as established conclusions from the provided August assessments.

Shadow shipping adds a second layer of risk

The supply problem is not limited to the volume of oil that can legally and safely move through the region. Windward identified the Koh-e-Mubarak anchorage as an active sanctions-evasion and ship-to-ship-transfer hub, with approximately 20 vessels assessed as involved and eight OFAC-designated vessels confirmed present.

That finding points to a more opaque shipping environment around the chokepoint. Some cargoes may continue moving through informal or higher-risk channels, but those operations create additional enforcement, insurance, safety, attribution, and escalation risks. As a result, a rise in vessel activity should not automatically be interpreted as a full restoration of normal oil trade.

Bottom line

The EIA’s August outlook is a forecast of near-term scarcity followed by an incomplete recovery. Brent averages about $87 per barrel in 2026 and falls toward $69 per barrel in 2027 as production and inventories improve. Yet the agency still expects roughly 600,000 barrels per day of Middle East disruption to persist through the end of 2027.

The IEA’s figures underline the immediate danger: supply losses are large enough to create a substantial deficit even after demand weakens, while inventories have already fallen sharply. The key variable for the next phase of the market is therefore not simply whether production restarts, but whether reliable, insured, and transparent shipping through the region can be restored.
