⚠ The Rulebook Is Written in Public NowHigh threat
Visa (V) — threat to the moat
Visa rarely loses the network and regularly loses a rule, and no rule it has lost has ever come back.
A rulebook that once operated quietly between member banks is now read line by line by merchants' counsel, competition authorities and legislatures on three continents. Anti-steering provisions have been litigated. Honour-all-cards has been litigated, and the Department of Justice has held an open civil investigative demand since 2012 into PIN-authenticated Visa Debit and the fixed acquirer network fee1. Interchange has been capped outright in Europe and constrained on debit in the United States.
The pattern is consistent: Visa rarely loses the network and regularly loses a rule. Each individual loss is survivable and the losses are cumulative — a little less control over routing, a little more merchant freedom to steer, a slightly lower ceiling on what the arrangement can earn. None of them has ever reversed.
That direction is the thing to watch rather than any single case, because the endpoint of a one-way ratchet is not a competitive market but a regulated utility, and utilities do not earn sixty percent operating margins.
