Two of the U.S. Senate's most vocal crypto advocates are now training their sights on a battlefield that extends well beyond digital assets. Senators Bernie Moreno and Cynthia Lummis have thrown their support behind the Credit Card Competition Act, a piece of legislation designed to dismantle the duopoly that Visa and Mastercard have maintained over U.S. payment networks for decades. The move signals that the pro-crypto wing of the Senate is broadening its mandate — from defending decentralized finance to actively challenging centralized financial infrastructure at its most entrenched.
The Duopoly Problem
For anyone operating in the payments space, the dominance of Visa and Mastercard is not an abstraction. The two networks together process the overwhelming majority of credit card transactions in the United States, giving them extraordinary pricing power over the interchange and routing fees that merchants pay every time a customer swipes a card. Those fees flow largely invisibly to consumers but hit retailers directly — and in aggregate, they represent one of the most significant and least scrutinized transfer mechanisms in the American economy. Merchants, particularly smaller operators with thin margins, have long argued they have no meaningful choice but to accept whatever terms the networks dictate.
What the Legislation Would Do
The Credit Card Competition Act takes direct aim at that dynamic by requiring that large financial institutions enable multiple payment network options on their credit cards, rather than exclusively routing through Visa or Mastercard. The logic is straightforward: if merchants can route transactions through competing networks, competitive pressure would drive down fees. Proponents argue the bill would not only reduce costs for merchants but potentially pass savings downstream to consumers, many of whom currently subsidize an expensive payments infrastructure without realizing it.
The endorsement from Lummis and Moreno adds political weight that the bill's backers will welcome. Lummis has established herself as perhaps the Senate's most prominent champion of digital asset legislation, having pushed consistently for regulatory clarity on bitcoin, stablecoins, and broader crypto market structure. Moreno, a newer but increasingly influential voice, has aligned closely with the pro-innovation, anti-incumbency sentiment that tends to animate both the crypto and fintech reform movements. That both senators are now lending their names to payments reform underscores how the conversation in Washington has evolved — the question is no longer just about which new technologies should be permitted, but about whether legacy gatekeepers should retain the structural advantages they have accumulated.
The Crypto Angle
The intersection with digital assets is more than symbolic. The case that crypto advocates have made for years — that decentralized payment rails can offer merchants faster settlement, lower fees, and freedom from intermediary rent-seeking — gains rhetorical force whenever the costs of the incumbent system are placed under a legislative microscope. If the Credit Card Competition Act advances, it would validate the underlying argument that the current payments architecture is neither inevitable nor optimal. That validation matters for the broader case that stablecoins, blockchain-based payment networks, and crypto-native financial rails deserve serious consideration as infrastructure alternatives, not merely speculative instruments.
There is also a more direct commercial dimension. As Coinbase, Stripe, and a growing number of fintech players push deeper into payments, any erosion of the Visa-Mastercard stranglehold creates market space for alternative networks to compete. Crypto-adjacent payment solutions stand to benefit from a regulatory environment that prizes competition over incumbency protection.
What This Means
The endorsement of the Credit Card Competition Act by two prominent pro-crypto senators represents more than a legislative maneuver — it reflects a maturing political coalition that sees payments infrastructure reform and digital asset advocacy as complementary rather than separate fights. Whether the bill can navigate the considerable lobbying firepower that Visa and Mastercard will deploy against it remains an open question. The two networks have historically proven adept at slowing or redirecting legislation that threatens their fee structures. But the political geography is shifting. Having credible, well-networked Senate sponsors who also carry significant weight in the crypto policy debate means the bill enters this cycle with more momentum than earlier iterations managed to generate. For merchants worn down by fees they cannot escape, and for digital asset builders who have long argued the incumbents are overprotected, that momentum is worth watching closely.
