The threat to the global economy doesn't just stem from Iranian retaliation, but also from the severity of the U.S. response. U.S. Treasury Secretary Scott Bessent recently noted that while the U.S. is issuing strict timelines for countries to sever ties with Iran under threat of dollar-system exile, the administration is intentionally rolling out these secondary sanctions with caution. When asked why the U.S. hasn't instantly severed all of Iran's partners from the financial network, Bessent bluntly asked, "Why would I want to blow up the global financial system?" confirming that a heavy-handed, immediate weaponization of the dollar risks accidental de-dollarization and massive economic warfare among major world powers.
If American economic war becomes too dangerous for Iran, Iran can use swarms of precise missiles and drones to destroy water supply and energy infrastructure of other countries there. The results would be catastrophic for the West.
“The Trump administration launched "Operation Economic Outcast" to squeeze Iran financially and try to force the regime into concessions to end the conflict in the Middle East.
Washington is warning world leaders to stop doing business with Iran and threatening to cut companies from the U.S. financial system should they do so. The U.S. is simultaneously blockading Iranian ports, choking off the regime's primary financial lifeline.
Iran, however, has spent years setting up a complex system of oil sales and clandestine shadow banking that it hopes will sustain its economy and military long enough to outlast the economic assault.
Here are the ways Tehran seeks to blunt U.S. power:
An oil stash
The U.S. naval blockade of Iran's ports has reduced Iranian oil exports -- its main revenue source -- to near zero. But Tehran still has millions of barrels of oil stored offshore in oil tankers, mainly in the waters off Malaysia. China buys more than 80% of Iranian oil exports, and although the blockade has limited deliveries, Beijing imported more than 500,000 barrels a day so far in August, according to data firm Kpler.
These deliveries rely on a ship-to-ship transfer system, where sanctioned tankers unload crude onto vessels in international waters off Malaysia to mask the fuel's origin. Those tankers then ship the cargo to China, where it is logged as a non-Iranian import. Ship-tracking company Vortexa estimates Iran has 80 million barrels of crude in floating storage.
China's currency
U.S. sanctions aim to cut off targets from the U.S. financial system, turning them into economic pariahs and threatening companies that trade with them. But sanctions become less effective if U.S. enemies seek to avoid the U.S. financial system and the U.S. dollar.
Iran sells most of its oil to China, including $6 billion worth of crude during a brief truce with the U.S. during the summer, and those transactions are increasingly settled in Chinese yuan. Iran then buys goods and services from China or it barters the oil in return for Chinese companies to build infrastructure inside Iran.
Crypto
Iran's crypto ecosystem has grown rapidly as sanctions have limited the regime's access to regular currencies such as the U.S. dollar. The Iranian regime has used billions of dollars in cryptocurrencies to conduct trades and acquire weapons and commodities, researchers say. Iran's Islamic Revolutionary Guard Corps has used crypto exchanges to get paid for oil sales, particularly from China.
In response, Washington has placed sanctions on Iranian exchanges and seized more than $1 billion in digital currency from Tehran. That has made it harder for Iran to move money. But policing the market is hard because much of the industry isn't regulated and transactions can be anonymous.
Shell companies
Iran still needs access to the dollar and other currencies to buy products and weapons and funnel money to its proxies such as Hezbollah and the Houthis, Western officials said. Tehran operates shell companies in hubs including Hong Kong and Dubai controlled by Iranian exchange houses.
The U.S. Treasury has used sanctions to target companies and individuals involved in this system. But it remains a game of whack-a-mole.
Shadow network
Iran's shadow system allows it to buy materials used to create drones, ballistic missiles and other weapons, largely from companies in China that sometimes are unaware of the ultimate buyer.
Even if the Chinese firms know that materials are to be delivered to Iran, these firms are often too small to care about U.S. sanctions or are disconnected from the global financial system.” [1]
