The moment America discovered its financial superpower: correspondent banking

When the dollar became a weapon
When John Kerry accused President Bush of not putting enough economic pressure on Iran with sanctions in their 2004 debate, Bush responded in a tone of exasperation. âWeâve already sanctioned Iran!â he said, looking into the camera. âWe canât sanction them any more.â
There was virtually no trade between the two countries by then, so there didnât seem to be anything left to sanction.
And yet, Iranâs shelves remained stocked with American-made consumer goods. âMaytag refrigerators, Diesel clothing and Victoriaâs Secret lingerie are quite popular,â the New York Times reported at the time.
Thousands of Iranian businesses were evading US sanctions simply by setting up offices and bank accounts in Dubai. âThe best place to do business in Iran,â one of these businesspeople told the Times, âis in Dubai.â
Arrangements like these had rendered US sanctions ineffective. But Bushâs comment in the presidential debate inspired one Treasury official to revisit them.
âStuart Levey took this sense of resignation as a personal challenge,â Edward Fishman writes in Chokepoints: American Power in the Age of Economic Warfare.
Levey was Under Secretary of the Treasury for Terrorism and Financial Intelligence at the time, tasked with finding ways to cut off funding for sanctioned groups and countries.
He reinvented how it was done. Fishman calls Levey a âfounding father of American financial warfare.â Others called him a âsanctions technocrat.â Still others, âa guerilla in a gray suit.â
Levey earned those monikers over 10 years of government service. But his enduring influence stems from a single insight: Banks could simply be told who not to deal with.
Leveyâs eureka moment came in 2006, when he read a newspaper account about a Swiss bank that had voluntarily cut all ties with Iran.
âIt sort of clicked for me,â he said later. âWhen we say weâre âall sanctioned out,â what we mean is that itâs illegal for US companies to do business with Iran. It does not mean the world has stopped doing business with Iran.â
The problem was that, while Iranian banks had been barred from dealing with US banks since the mid â90s, they still had indirect access to the US banking system through correspondent banking.
To pay for something in dollars, Iranian banks would send money to a European or Asian bank, which would then route it to a recipient through a US correspondent bank â a bank that settles dollar transactions on behalf of other banks.
It seems like an obvious loophole now, but before Levey, no one in government had thought much about this niche corner of the financial system. To the extent they had, there seemed little to be done. Stopping these transactions appeared to require the painstaking work of convincing other governments to instruct their banks to stop transacting with Iran.
Leveyâs insight was that he could appeal to the banks directly.
âFrom his time in private law practice,â Fishman wrote, âLevey was familiar with how corporate executives thought about regulatory and reputational risk. He believed he could persuade them to cut ties with Iran of their own accord, whether their home governments were on board or not.â
The persuasion came mixed with a warning: Treasury would be looking for violations of US sanctions enabled by correspondent banking.
âWe never threaten,â Treasury Secretary Hank Paulson told Fishman. âWe talk about how important it is not to violate the rules and engage in illicit transactions.â
Nice bank you have thereâŠ
The implied threat was that violating US sanctions law could lead to large fines or even losing access to US correspondent banks and therefore the ability to move dollars.
Not every bank received the message kindly.
Fishman cites a response from the second-in-command at Standard Chartered: âYou fucking Americans. Who are you to tell us, the rest of the world, that weâre not going to deal with Iranians?â
They found out a few years later when US law enforcement agencies fined Standard Chartered $359 million for sanctions violations.
Others required no persuasion at all.
âWe havenât had Chinese banks tell me that they wonât do deals with Iran,â Levey told Fishman. âThey just stop.â
âEighteen months into the campaign, nearly all the worldâs largest banks had stopped servicing transactions with Iran, even though neither their own governments nor the UN required it,â Fishman wrote.
A measure of the effectiveness of Leveyâs campaign is that the governor of Iranâs Central Bank labelled it an act of âfinancial terrorism.â
But one manâs financial terrorist is anotherâs financial freedom fighter. Fishman calls the campaign an act of economic war.
Treasury Secretary Scott Bessent prefers the term âeconomic statecraft.â
Leveyâs per Diem
In a talk last month, Secretary Bessent defined economic statecraft as âthe disciplined use of Americaâs economic power in service of our sovereignty.â
This includes the power that Levey had discovered. Access to the dollar system, Bessent said, is âno longer unconditional.â
In truth, itâs been conditional for some time now. Even before Levey, the US denied access to its banking system as a way to punish adversaries like Cuba and Libya.
Leveyâs discovery was just how much of a chokepoint the dollar system could become, and how the US could use it to pursue its geopolitical goals.
Bessentâs emphasis on economic statecraft is a declaration that the US intends to use it even more aggressively.
Fishman would likely applaud the idea â he believes economic war can be an effective alternative to kinetic war.
To that end, he suggests that the US create âa permanent economic war councilâ that would make quicker and better policy recommendations in a crisis.
But he also warns that it wonât work forever. Financial sanctions are like antibiotics, he says: They are effective in high doses, but lose their potency if overused.
The US is probably overusing them already, as evidenced by the increasing measures its adversaries â and its friends, even â are taking to create alternatives to the dollar system.
Some of these alternatives involve crypto, including the billions of dollars that Iran has moved in stablecoins in recent years.
The potential for stablecoins to be used in sanctions evasion is why Stuart Levey joined Facebookâs stablecoin project, Diem, as CEO in 2020 â âbecause he wanted to ensure digital currencies would not undermine American financial power,â Fishman wrote.
Diem shut down less than two years later, unfortunately.
But Levey â the founding father of American financial warfare â landed on his feet.
As chief legal officer at Oracle, he made $14.5 million last year.
