In a move that has stunned global markets and foreign policy experts alike, the Trump administration announced last Friday that it is temporarily lifting sanctions on 140 million barrels of Iranian crude oil currently at sea. The decision comes amid the ongoing U.S.-Israeli military campaign against Iran, a conflict that has already caused major disruptions to global energy markets.
“This is an unusual and striking turn in U.S. sanctions policy,” said one analyst familiar with the administration’s energy strategy. “You don’t often see countries lift sanctions on adversaries during active hostilities.”
From Maximum Pressure to a Strategic Pivot
The Trump administration’s approach to Iran has been aggressive from the outset. In February 2025, President Trump announced a “maximum pressure” campaign aimed at cutting Iran’s oil exports to zero. In his announcement, he instructed the Treasury Department to “implement a robust and continual campaign, in coordination with the Secretary of the Treasury and other relevant executive departments or agencies, to drive Iran’s export of oil to zero, including exports of Iranian crude to the People’s Republic of China.”
By November, the Treasury had imposed new sanctions targeting a network of front companies and shipping facilitators that financed the Iranian armed forces through crude oil sales. “Today’s action continues Treasury’s campaign to cut off funding for the Iranian regime’s development of nuclear weapons and support of terrorist proxies,” said Secretary of the Treasury Scott Bessent. “Disrupting the Iranian regime’s revenue is critical to helping curb its nuclear ambitions.”
Yet despite these efforts, Iran demonstrated its ability to strike back. The conflict escalated with drones, missiles, and mines targeting oil tankers, port facilities, and refineries. Oil prices surged from roughly $58 per barrel to between $90 and $98 per barrel, while gasoline prices in the U.S. spiked in response.
Treasury’s Sudden Shift
On Friday, however, the Treasury Department reversed course with a narrowly targeted, short-term authorization to permit the sale of Iranian oil currently stranded at sea. In a statement, the department explained:
"At present, sanctioned Iranian oil is being hoarded by China on the cheap. By temporarily unlocking this existing supply for the world, the United States will quickly bring approximately 140 million barrels of oil to global markets, expanding the amount of worldwide energy and helping to relieve the temporary pressures on supply caused by Iran. In essence, we will be using the Iranian barrels against Tehran to keep the price down as we continue Operation Epic Fury."
The rationale, as described by Bessent on Meet the Press, was both tactical and economic. He explained:
"Again, Kristen, why don’t we have good facts here? That Iranian oil was always going to be sold to the Chinese. It was going to be sold at a discount. So which is better, Kristen? The uh, which is better? If oil prices spike to $150 and they were getting 70 percent of that? Or oil prices below $100? It’s better to have them where they are now… We are using their own oil against them. We have a much better line of sight, to be clear, at Treasury, when this oil goes to — if it goes to Indonesia, if it goes to Japan, if it goes to Korea, we have a much better line of sight and are able to block accounts that the oil goes into."
He continued to detail the potential supply impact:
"140 million barrels — about 20 million barrels a day — comes out of the Gulf. About 5 million has been repurposed by the Saudis, by the UAE. So, we are at a 15 deficit. About 1.5 is Iranian oil that comes out. So, we are at between a 10 and 14 million deficit on a daily basis. So if you think about 140 million barrels, that’s between ten days and two weeks of supply."
Theory vs. Reality
While Bessent framed the policy as a clever workaround to global oil shortages, the actual impact on markets remains uncertain. China has long been stockpiling Iranian oil and has the world’s largest strategic reserves. Paying Iran for an additional 140 million barrels is unlikely to change its stockpiling behavior, meaning the oil may not flow to other buyers as intended.
The administration’s argument rests on the fungibility of oil: if China buys more Iranian oil, it may free up other barrels for countries such as Japan, Korea, Indonesia, or Malaysia. However, as of this writing, there is no public evidence that tankers carrying the newly sanctioned oil are diverting to these nations. Historical precedent with Russian oil shows it is possible for shipments to be redirected mid-voyage, but the effect on actual market prices has been modest. Crude oil futures have barely moved since the announcement, hovering around $102 per barrel after initially dropping from $111.
Iran’s Leverage in the Strait of Hormuz
Complicating matters, Iran has established mechanisms to extract revenue from maritime trade through the Strait of Hormuz. Lloyd’s List reports that Tehran has created a “de facto ‘safe’ shipping corridor,” where vetted vessels can pass in exchange for approval — and sometimes payments, reportedly up to $2 million in at least one instance. Coupled with higher oil prices, Iran’s potential revenue has soared. The Kpler Institute estimates that the recent conflict’s $47 increase in oil prices per barrel generated roughly $8.7 billion in profits from Iran’s oil sales.
“The war to eradicate Iran’s ability to threaten its neighbors and our allies has instead highlighted Iran’s ability to leverage its position economically and geopolitically,” analysts note. While military operations continue, the regime demonstrates that it can still influence energy markets globally.
Cost of War and Policy Implications
The financial burden of the conflict is significant. The Pentagon has requested roughly $200 billion to sustain military operations in Iran, with daily costs estimated at approximately $1 billion. While a regime change could potentially justify these expenditures in the administration’s view, there is skepticism about the ultimate political outcomes. Reports from Politico indicate that talks with Iranian parliament speaker Mohammad Bagher Ghalibaf regarding a transition of power are either non-existent or in very early stages. Ghalibaf has publicly demanded “complete and humiliating punishment” for the U.S. and reparations, casting doubt on the conflict’s ability to deliver decisive political results.
Even with these military efforts, the war has created unintended economic consequences. Oil markets remain volatile, Iran’s revenue continues to climb, and the cost of restoring normal shipping patterns could take months. Richard Meade of Lloyd’s List warns:
"What happens next is far from clear, but even the best-case scenarios now contain an assumption that shipping will take months to return to some semblance of normalised trading patterns even after the fighting stops… security is going to be required and given that the US has made it clear that will be a responsibility for others to take on, the limited diplomatic discussions are starting to focus on what that looks like."
Lessons and Controversies
The decision to lift sanctions on Iranian oil highlights a recurring tension in U.S. foreign policy: the balance between strategic military objectives and economic realities. Conservative critics previously opposed the Obama administration’s $1.7 billion cash transfer to Iran as part of a nuclear deal. Yet the current war, designed to weaken Tehran, has inadvertently enriched the regime through higher oil prices.
Moreover, the policy demonstrates how sanctions, even when meticulously designed, can be undercut by global market dynamics. While Bessent described the move as “jujitsuing” the Iranians, the actual ability of the U.S. to control oil flows once the product is at sea is limited. China’s stockpiling practices and Iran’s control over the Strait of Hormuz ensure that Tehran retains significant leverage over global energy markets.
Conclusion
The Trump administration’s lifting of sanctions on 140 million barrels of Iranian oil is a bold and unconventional move, reflecting the complexities of modern warfare, energy security, and global finance. While framed as a strategy to reduce global oil prices and undercut Iran’s profits, the immediate effects on markets are uncertain, and the geopolitical consequences remain unpredictable.
As the U.S.-Israeli campaign against Iran continues, policymakers, investors, and energy consumers alike are watching closely. What is clear is that even in the midst of military pressure, Iran retains significant economic and geopolitical tools. In the coming months, the interplay between sanctions, oil markets, and regional security will shape not only the conflict’s outcome but the global energy landscape for years to come.
