Iran’s Oil Exports and the Global Market: Flows, Sanctions, and Chokepoints

Iran’s role in global energy markets is shaped by its substantial oil reserves, ongoing international sanctions, and the strategic importance of regional shipping routes. The country’s export patterns and the use of alternative shipping methods have implications for market transparency and pricing.

Iran is among the top global holders of proven crude oil reserves, with estimates placing its reserves at approximately 208 to 209 billion barrels. This positions Iran within the top three or four countries worldwide in terms of oil reserves. The country’s ability to export oil is influenced by international sanctions, which have led to changes in how its oil reaches the market.

Despite ongoing sanctions, Iran’s oil exports in 2025 reached their highest level in seven years. These exports have increasingly relied on opaque shipping networks, often referred to as the “shadow fleet,” which complicate tracking and raise the cost of enforcement for international regulators. This approach also introduces uncertainty in oil pricing due to reduced transparency.

In 2025, Iran’s average daily exports included about 1.7 million barrels of crude and condensates, 0.6 million barrels of refined products, and 0.4 million barrels of natural gas liquids. The majority of these exports, over 90%, were directed to China, reflecting the limited range of buyers willing to engage with Iran under current sanctions.

What the numbers show

• Iran exported around 1.7 million barrels per day of crude and condensates in 2025
• Approximately 20 million barrels per day passed through the Strait of Hormuz in mid-2025
• A one-month halt in Strait of Hormuz flows could add $14 per barrel to oil prices

The Strait of Hormuz remains a vital route for global energy supplies, with about one-fifth of the world’s oil and liquefied natural gas passing through this narrow waterway. In mid-2025, roughly 20 million barrels of oil per day transited the strait, representing over a quarter of all oil traded by sea and nearly one-fifth of total global consumption.

Market assessments indicate that a complete one-month disruption of shipments through the Strait of Hormuz could result in an estimated $14 increase per barrel in oil prices. This highlights the region’s influence on international energy costs and the sensitivity of markets to potential supply interruptions.

Historical data shows that if sanctions on Iran were lifted following regime change, the country has previously increased production by 600,000 to 800,000 barrels per day within several months. This level of growth would represent approximately 4% of global oil output, based on past responses to changes in sanctions.

Analyst statements reported in 2025 indicated that, if Iran’s government perceived an existential threat, actions such as targeting Gulf energy infrastructure, mining the Strait of Hormuz, or interfering with ship tracking systems could take place. Such moves could disrupt energy shipments for extended periods, according to these assessments.
