⚠ A Regulator Can Do What a Competitor CannotHigh threat
Visa (V) — threat to the moat
A central bank can dissolve in a year the deadlock that has defeated every private entrant for fifty.
This facet's strength is exactly its vulnerability. Visa is close to invulnerable against any rival that has to persuade both sides of a market, and close to defenceless against any authority that can skip the persuading. Pix went from about 1% of Brazilian transactions in the fourth quarter of 2020 to 52% by the first half of 20251, from nothing, because the central bank required the banks to offer it and set the price at zero.
The mechanism does not require the state rail to be better, faster or more pleasant to use. It requires only that it be present at the point of sale and free, at which point the merchant — the party that pays the fee and has never had a vote — acquires one for the first time in fifty years. The merchant then has a reason to steer, and steering is the thing the network's rules have always been written to prevent.
What Visa retains against a state rail is everything account-to-account transfer does not provide: revolving credit, chargeback rights, fraud liability that sits with someone else, rewards, and acceptance in the other two hundred countries. Those are real and they are why Pix took the everyday low-value payment in Brazil rather than the aspirational one. Watch the share of domestic transactions running on state schemes in Visa's larger emerging markets; that is what turns a structural argument into a revenue line.
