Long-Term Oil Price Outlook: 2030 and Beyond

The peak demand debate

For most of the last decade the central question has been when global oil demand will peak. The IEA's answer depends on the scenario. Under its Stated Policies Scenario, growth in electric vehicles, efficiency and fuel switching in China and other markets causes demand to plateau around 2030 at about 102 mb/d. In its 2025 report the IEA reinstated a Current Policies Scenario, in which demand grows to 113 mb/d by 2050, supported by petrochemicals, aviation and trucking.

OPEC rejects the near-term peak. Its 2026 outlook raised its 2050 demand forecast to 124.1 mb/d from 122.9 mb/d a year earlier, citing policy shifts in the US, EU and elsewhere that support oil use, and energy security concerns heightened by the war in the Middle East. OPEC expects most of the growth to come from developing economies outside the OECD. See China oil demand for why the largest importer's demand has slowed.

Supply investment: the other side of the price

Oil fields decline naturally, so the industry must keep investing just to hold output flat. The IEA's 2025 outlook says around 25 mb/d of new oil supply projects are needed by 2035 in its Current Policies Scenario to keep markets balanced. OPEC's Secretary General put the investment requirement at $17.7 trillion from 2026 to 2050, or more than $700 billion a year.

Underinvestment is the main argument for higher long-term prices. If demand stays near current levels and spending on new supply falls short, prices have to rise to attract it. Conversely, if demand plateaus while US shale, Brazil, Guyana and Canada keep growing, the world could face spare capacity and lower prices. Background on US supply is in US oil production.

What could keep oil above or below $70 to 2030

$70 per barrel is a useful marker: Brent averaged $69 in 2025 before the 2026 shock, and the EIA's AEO 2026 base case keeps it below $70 in real terms through 2030. The forces pulling in each direction:

How the 2026 shock changes the long view

The 2026 disruption, covered in oil price history 2026, has been one of the largest supply shocks in decades: the EIA estimates crude production shut-ins peaked at 10.9 million b/d in May 2026. History suggests big shocks have lasting effects on both sides of the market. The 1970s oil crises led to more non-OPEC production, strategic reserves and efficiency standards, which eventually lowered prices in the 1980s. A similar response now could include more bypass pipelines (the EIA expects new UAE bypass capacity in 2027), larger emergency stocks, faster electrification in importing countries and new investment outside the Gulf.

The near-term outlooks summarised on our oil price forecast page already expect prices to fall in 2027 as supply returns. The long-term question is where they settle afterwards.

How to read long-term forecasts

• Check the dollar basis. Long-term outlooks usually quote real (inflation-adjusted) prices, so $80 in 2035 is not the same as $80 in that year's money. See inflation-adjusted oil prices.
• Scenarios are not forecasts. The IEA explicitly presents scenarios to explore outcomes, not a single most-likely path.
• Know the author's perspective. Producer groups, consumer-country agencies and banks have different assumptions and incentives.
• Look at the drivers covered in what moves oil prices, and how OPEC+ manages supply.
