Iran Sanctions Unwind Creates Compliance Bottleneck for Banks

The White House is moving to unwind decades of Iran sanctions, a shift that is creating compliance headaches for U.S. banks. A June 17 memorandum of understanding between President Trump and Iranian President Masoud Pezeshkian calls for removing all U.S. sanctions on an agreed schedule. The Treasury Department will issue 60-day waivers on existing sanctions as technical negotiations continue.

The pace and scale have left sanctions observers stunned, Bloomberg News reported Sunday. Former Treasury officials, sanctions attorneys, and industry sources said the change will be tough to implement in a way that appeals to risk-averse American financial institutions.

Adam Smith, a former senior adviser to the director of the Treasury's Office of Foreign Assets Control, said banks want to be 100% sure they are within compliance. “One-off transactions that close within the 60 days could work. There may be challenges finding banks and other intermediaries willing to process transactions,” he said.

Michael Huneke, a trade and national security lawyer at Morgan, Lewis & Bockius, added that financial institutions tend to be more risk-averse than their clients when sanctions programs wind down. “I would expect them to be very cautious here as well,” he said.

The Bloomberg report noted that moving too quickly and incurring a violation is not attractive. BNP Paribas paid a nearly $1 billion settlement in 2014 for allegedly violating sanctions against Iran and Sudan.

For oil markets, the sanctions unwind could eventually add supply. Iran has been under heavy restrictions. The promise to unblock frozen funds and permit oil sales raises the possibility of increased exports. The compliance bottleneck means any increase will be gradual. Banks are waiting for clear Treasury guidance before processing Iran-related transactions. The 60-day waivers have not yet been issued.

A gradual return of Iranian oil would cap crude price gains, all else equal. That would feed into lower inflation expectations and could shift the Fed's rate path. The crude oil profile shows how supply shocks have historically moved prices. The MWLIX Returns 0.22% as Energy Inflation Reshapes Rate Expectations article details the mechanism.

The compliance bottleneck is the key variable. If Treasury issues the waivers and banks still refuse to process transactions, the oil supply effect will be delayed. If banks get comfortable, Iranian exports could rise meaningfully within 12–18 months. The next concrete marker is the Treasury's first 60-day waiver issuance, which has no announced date.
