⚠ If Interchange Goes, So Does the DistributionHigh threat

Visa (V) — threat to the moat

A cap does not take Visa's revenue; it takes the issuer's enthusiasm, and that arrives on Visa's income statement as a higher incentive bill.

Europe's caps did not damage the networks directly. They compressed issuer economics, which is why European card rewards are thin next to American ones and why European cards compete less hard for a place in the wallet.

Europe after 2015 is the worked example: the networks came through comfortably and issuer economics did not.

That is the transmission mechanism to watch in the United States, where interchange has been under legislative attack for two decades and debit is already capped. Visa's revenue is insulated from a cap by construction. Its distribution is not: a bank earning less on each swipe has less reason to market the card, a smaller budget for the rewards that drive usage, and a stronger negotiating position when the network next bids for its portfolio.

All three of those show up in the same place — client incentives as a share of gross revenue, $15,751 million of $55,751 million, or 28.3%, in fiscal 20251, and rising. A cap on interchange would most likely appear in Visa's accounts not as lower revenue but as a higher price for keeping the issuers it already has.
