Iran’s crude oil exports have collapsed from roughly 2 million barrels per day to below 300,000 bpd in May 2026. Some analyses put the real number even lower: effectively zero crude leaving Iranian ports during parts of that month.
The cause is a US naval blockade launched in April 2026, and the financial damage is staggering. Estimated revenue losses range from $4.8 billion to nearly $6 billion, with daily losses running around $400 million.
How the blockade works, and why it matters for crypto
The blockade itself is only one layer of a broader campaign the Trump administration has branded “Economic Fury.” Alongside the naval interdiction, Washington has rolled out fresh sanctions targeting the shipping networks and foreign intermediaries that have historically helped Iran move oil to willing buyers.
Hong Kong-based facilitators who brokered Iranian crude sales to China have been singled out. In late May and early June, US sanctions actions extended beyond oil infrastructure to target Iranian digital asset exchanges linked to the Islamic Revolutionary Guard Corps. The US Treasury has frozen nearly half a billion dollars in regime-linked crypto assets as part of the broader pressure campaign.
