WASHINGTON, July 11 — The economic architecture of pressure on Iran has been decades in the making, but its most defining chapter began in 2012, when the United States targeted Iran’s oil exports with the most comprehensive sanctions yet. Those measures, and the ones that followed, have reshaped the Iranian economy, its global trade relationships, and the lives of millions. The sanctions trace their origin to the 1979 hostage crisis, but the current framework is built on a series of escalating actions.
The 2015 Joint Comprehensive Plan of Action, known as the JCPOA, offered a temporary reprieve. Under that deal, many sanctions were lifted in exchange for strict nuclear restrictions.
But the architecture shifted again on May 8, 2018, when President Donald Trump withdrew the United States from the agreement and began reimposing the sanctions that had been suspended.
The oil chokehold
The effect on Iran’s oil sector was immediate and severe. According to the International Energy Agency, Iran’s oil exports fell from 2.5 million barrels per day in 2018 to under 500,000 barrels per day in 2020. That collapse stripped the Iranian government of its primary revenue source.
By 2023, exports had partially recovered to around 1.5 million barrels per day, but the recovery came with a caveat. Nearly all of that oil was going to China, the only major buyer willing to navigate the sanctions regime.
The U.S. Treasury Department’s Office of Foreign Assets Control, known as OFAC, is the agency that enforces these restrictions, and its reach extends beyond oil.
Beyond oil: a widening net
In 2023, the United States imposed additional sanctions on companies and individuals affiliated with Iran’s Islamic Revolutionary Guard Corps, specifically targeting those involved in drone production. The sanctions have also swept up Iran’s central bank, as well as its metals and automotive sectors, creating a web of restrictions that touches nearly every corner of the formal economy. The human cost of these measures is visible in the data.
The World Bank reports that Iran’s GDP contracted by 6% in 2019. By 2020, inflation had reached 40%.
For Iranian families, that meant the purchasing power of the rial evaporated, even as the price of basic goods climbed.
What to watch next
The sanctions remain a central tool of U.S. policy toward Iran, enforced by OFAC and calibrated to target both the regime’s nuclear ambitions and its regional military activities. With the 2026 calendar now past the midpoint, the question for policymakers is whether the current pressure campaign will yield further concessions, or whether Iran’s partial recovery in oil exports — and its deepening ties to China — will allow it to weather the storm.
