Needing Dollars, Iran-Backed Militias Turn to Visa and Mastercard

Iraq was a minor market for Visa and Mastercard a couple of years ago, generating just $50 million a month or less in cross-border transactions at the start of 2023. Then it exploded to around $1.5 billion in April that year, a 2900% increase almost overnight.

What changed? Iraqi militia groups figured out how to squeeze dollars on an industrial scale from Visa and Mastercard’s payment networks for themselves and for their allies in Iran, according to U.S. and Iraqi officials and documents reviewed by The Wall Street Journal.
