Economic sanctions aren't the magic wand Washington thinks they are. We’ve seen this movie before. Between 2017 and 2021, the Trump administration leaned into a "maximum pressure" strategy, betting that if you just squeezed the bank accounts of Iran and Venezuela hard enough, the regimes would crumble or at least come crawling to the negotiating table. Fast forward to 2026, and the wreckage of that theory is everywhere.
The logic was simple: cut off the oil, freeze the assets, and wait for the "unconditional surrender." It sounds great on a campaign trail. In reality, it didn't work. Nicolás Maduro is still in Miraflores Palace, and Tehran didn't stop its enrichment programs because of a Treasury Department memo. Instead of collapsing, these countries got creative. They built "shadow fleets," found new best friends in Beijing and Moscow, and learned how to live in the dark. For another perspective, read: this related article.
The Mirage of Total Isolation
You can’t isolate a country that has something the rest of the world wants. For Iran and Venezuela, that "something" is oil. The U.S. tried to lock the front door of the global financial system, but it forgot about the windows.
When the U.S. revoked licenses for Western companies to operate in Venezuela, it didn't stop the oil from flowing. It just changed who was holding the bucket. Chinese "teapot" refineries stepped in, buying up Venezuelan crude at steep discounts. They didn't care about U.S. sanctions because they don't use U.S. dollars. By the time 2020 rolled around, Maduro had passed an "Anti-Blockade Law" that allowed him to sign secret deals with anonymous Chinese firms. The oil moved on "ghost tankers" with their transponders turned off, relabeled as "Malaysian bitumen" to dodge the heat. Similar insight regarding this has been published by The Guardian.
In Iran, the story was the same. The U.S. exit from the JCPOA in 2018 was supposed to be the death knell for the Iranian economy. Sure, the rial tanked and inflation skyrocketed, but the regime didn't blink. They leaned into their "Look East" policy. China became a lifeline, reportedly importing hundreds of thousands of barrels a day through the same shadowy networks.
Driving Adversaries Into Each Other's Arms
One of the biggest backfires of the maximum pressure era was how it forced a "marriage of convenience" between America's rivals. If you treat everyone like an outcast, they’re going to start their own club.
Before the heavy sanctions hit, Iran and Venezuela were partners, sure, but they weren't inseparable. Sanctions changed that. When Venezuela's refineries started falling apart because they couldn't get U.S. spare parts, Iran sent its own engineers and diluents. They traded Iranian condensate for Venezuelan heavy crude. It was a barter system that bypassed the Western banking world entirely.
Russia jumped in too. When the U.S. pressured Western shippers to stay away, Russian state-run oil companies like Rosneft took over the logistics for Caracas. By the time the U.S. sanctioned Rosneft’s subsidiaries in 2020, the damage was done—the trade routes were established. We didn't just hurt these regimes; we gave them a reason to build a parallel economy that we can't see or touch.
The Human Cost That Doesn't Make the Headlines
It’s easy to talk about "sectoral sanctions" in a briefing room. It’s a lot harder to explain why kids in Caracas can’t get dialysis.
The theory is that if you make life miserable enough for the average citizen, they’ll rise up and overthow the government. History says otherwise. Usually, they just get tired, hungry, and dependent on the regime for food boxes. In Venezuela, researchers linked the 2017-2018 sanctions to an estimated 40,000 excess deaths. Hospitals ran out of antibiotics and soap. Even when "humanitarian exemptions" exist on paper, they don't work in practice. Banks are so terrified of accidentally violating a U.S. rule that they block transactions for medicine and food just to stay safe.
In Iran, the same "over-compliance" meant that during the height of the pandemic, the country struggled to secure the financial channels needed for vaccines and medical equipment. Does this weaken the regime? Rarely. It mostly just weakens the middle class—the very people who might actually want a more democratic future.
Why the Leverage Never Materialized
Sanctions are supposed to be a tool for negotiation, not an end in themselves. The Trump administration’s mistake was thinking the pressure was the victory.
If you don't give a regime a clear, believable "off-ramp," they have no reason to change. If Tehran believes that even if they comply, the U.S. will just find another reason to keep the sanctions on, they’ll just keep digging their heels in. We saw this play out in 2025 and early 2026. The more the U.S. leaned into military threats and "Operation Epic Fury," the more the Iranian leadership felt they had nothing to lose by escalating.
Maximum pressure isn't a strategy; it's a posture. It looks tough on TV, but it's remarkably ineffective at actually changing behavior.
Moving Past the Maximum Pressure Playbook
If you want to understand where U.S. foreign policy goes from here, you have to stop thinking of sanctions as a "set it and forget it" solution. They’re a blunt instrument that gets duller the more you use it.
Here is what actually moves the needle:
- Targeted Licensing: Instead of blanket bans that drive trade underground, use specific licenses (like the ones given to Chevron) to keep some level of visibility and influence over the oil flows.
- Multilateralism or Bust: Unilateral U.S. sanctions are a joke if China and India are willing to buy the product. Without a global consensus, you’re just shifting the profits from Western companies to Eastern ones.
- Real Off-Ramps: You have to be willing to lift the pressure in exchange for verified steps. If the "ask" is unconditional surrender, you’re going to get a fight, not a deal.
The lesson from the last few years is clear. You can't starve a regime into submission if they have friends with deep pockets and a fleet of ghost ships. It’s time to stop pretending otherwise.
If you’re tracking how these geopolitical shifts affect energy prices, start looking at the "shadow fleet" volumes in the Malacca Strait rather than just the official OPEC reports. That's where the real market is happening now.
