The U.S. sanctions regime on Iran's oil exports aims to constrain Tehran's revenue and nuclear ambitions, but its effectiveness remains contested. As of mid-2026, the strategy faces new pressures: Iran has proposed tolls on tankers transiting the Strait of Hormuz (a chokepoint for 20% of global oil), while the Trump administration debates whether to counter with its own toll scheme or military enforcement. The debate hinges on whether sanctions are degrading Iran's economy enough to force concessions, or whether they're simply reshaping global trade patterns and pushing Iran toward alternative revenue sources.
