EIA expects Brent oil to ease from about $85 as supply recovers
The EIA expected Brent crude to average about $85 a barrel in Q3 2026 before easing to around $69 in 2027 as inventories rebuild. This gives students a specific, current supply-shock example rather than a generic statement that oil prices are volatile.
What happened
The U.S. Energy Information Administration’s August 2026 outlook incorporated supply disruption and subsequent recovery into its energy forecast. It projected Brent crude at about $85 per barrel in Q3 2026 and around $69 in 2027 as global inventories rebuild.
Why it matters
Oil is an input into transport, logistics, manufacturing and energy. Higher oil costs can shift SRAS left, raising cost-push inflation and reducing real output. Lower future oil prices can ease that pressure, while oil exporters face a different income and trade effect from importers.

Key evidence
Brent forecast, Q3 2026
EIA forecast Brent crude at about $85 per barrel in the third quarter of 2026.
Brent forecast, 2027
The outlook projected Brent at around $69 per barrel in 2027 as inventories rebuild.
Direction of supply pressure
The forecast linked the expected price easing to recovery in supply and rebuilding global inventories.
Best diagram

- 1Draw an AD/AS diagram with an initial SRAS curve.
- 2For a rise in oil prices, explain that firms face higher transport and production costs.
- 3Shift SRAS left and show a higher price level with lower real output.
- 4For the forecast fall in oil prices, explain that the cost pressure can partly reverse, allowing SRAS to shift back right if the lower prices are sustained.
Chain of analysis
Step 1
Oil prices rise or remain elevated because global supply is disrupted relative to demand.
Step 2
Energy, transport and production costs rise for firms that use oil directly or indirectly.
Step 3
Firms are willing and able to supply less at each price level, shifting SRAS left.
Step 4
The price level rises, creating cost-push inflation.
Step 5
Real output falls, weakening short-run growth.
Step 6
If supply recovers and oil prices fall as forecast, part of the cost shock can unwind, reducing inflation pressure and supporting output.
Counter-case
When might the main chain weaken?
Use these conditions to challenge the initial mechanism rather than assuming the effect is automatic.
Forecast uncertainty
The $85 and $69 figures are forecasts, not guaranteed outcomes. Geopolitical events and producer decisions can alter supply quickly.
Energy intensity
The impact is larger for transport, aviation, chemicals and energy-intensive manufacturing than for sectors that use little oil.
Importers versus exporters
Oil-importing economies may suffer a terms-of-trade and cost shock, while oil exporters can gain income and government revenue from higher prices.
Pass-through
The inflation effect depends on whether firms absorb higher costs in profit margins or pass them through into consumer prices.
Judgement
Oil-price effects differ between importing and exporting economies and depend on how persistent the price move is, how energy-intensive production is and whether firms pass costs on to consumers.
Use it in a 15-marker
Use one or two pieces of the key evidence, explain the mechanism clearly, and use the diagram to anchor the causal chain. Keep evaluation focused on the condition in the judgement rather than adding unrelated points.
Use it in a 25-marker
Use the EIA’s $85 Q3 2026 forecast and $69 2027 forecast to show both the shock and the expected unwind. Analyse higher oil prices through SRAS and cost-push inflation, then evaluate the forecast uncertainty, energy intensity, importer/exporter status and cost pass-through.
Practice question
Evaluate the likely effects of a sustained rise in world oil prices on an oil-importing economy.
