Iran could gain access to new oil revenue under a temporary United States sanctions reprieve, but the measure does not automatically release the much larger volume of assets accumulated abroad under decades of restrictions. Funds held or restricted in India, China, Iraq and other jurisdictions remain tied to separate legal and financial controls.
The opening follows a 14-point memorandum between Washington and Tehran. The United States has issued a temporary general licence allowing the production, delivery and sale of Iranian crude oil, petrochemicals and petroleum products until August 21, including related banking, insurance and transport operations.
The licence could generate as much as $3 billion for Iran over two months. Its immediate effect is to facilitate payment for current energy sales, rather than fully restoring access to previously frozen holdings or normalising Iran's position in the international financial system.
A wider rollback would be significantly more complex. The sanctions framework combines presidential orders, legislation passed by Congress, international restrictions and thousands of designations covering individuals, companies, ships and aircraft. Executive measures can be revoked by the White House, but statutory sanctions require congressional action.
Administrative work would also take time. More than 1,000 Iran-linked individuals, vessels and aircraft have been designated by the US Treasury since early 2025, while removing thousands of entries from sanctions lists could extend for at least a year. Separate restrictions imposed by Britain, the European Union and other jurisdictions would remain outside a US decision.
Commercial confidence presents another obstacle. Banks, insurers and energy companies would still need to conduct extensive compliance reviews, assess exposure to sanctions-evasion networks and consider litigation risks. Even with formal relief, large-scale investment is unlikely to return until the new framework appears durable and politically stable.
