Iran produces about 4.05 million barrels of crude per day (2025) and holds ~208.6 billion barrels of proven reserves (#3 worldwide). A founding OPEC member with the world's third-largest reserves, Iran is the market's perennial geopolitical variable — its exports swing by more than a million barrels a day depending on sanctions enforcement.

Iran produces about 4.05 million barrels per day of crude oil (including lease condensate, 2025). Source: EIA international statistics.
Iran holds roughly 208.6 billion barrels of proven crude reserves (OPEC Annual Statistical Bulletin, 2023), the #3 largest in the world. Proven reserves shift with prices and technology — see the caveats on the oil-reserves page.
Estimates from tanker trackers put exports at roughly 1–1.5 million barrels per day in recent years, overwhelmingly to China. The volume flexes with US enforcement intensity — it fell near 0.4 Mb/d at maximum pressure in 2020 and recovered afterward.
Losing over a million barrels a day would tighten the market meaningfully — likely a $5–15 rise depending on spare capacity — but the bigger risk premium comes from escalation scenarios around the Strait of Hormuz, through which about a fifth of world supply passes.
