P2P payments app Zelle, backed by big US banks, says 70%+ of transfers are between pairs of customers who have accounts at the same institution

Context & Ripple Effects
Since launching in 2017 inside participating banks' own apps, Zelle has scaled fast on distribution it didn't have to buy — $75B moved in its first full year, en route to $1T in annual volume by 2024. But this disclosure cuts against the consortium pitch: with 70%+ of transfers staying between customers of the same institution, the network is behaving less like a shared rail and more like a bundle of per-bank silos.
That matters because Zelle was built by 30+ rival banks to counter Venmo, and the same-bank skew suggests the incumbents' cooperation extends mainly to branding, not to making cross-institution transfers as seamless as internal ones.
First-order effects
- Venmo's differentiation holds where it matters most: Zelle's same-bank dominance means the cross-bank experience — the whole point of a consortium network — remains the weak link for the banks backing it.
- Banks get real-time settlement cheaply for their own customers, but each institution effectively operates its own P2P product under a shared name rather than contributing to one network effect.
Second-order effects
- Fraud exposure concentrates accordingly: when sender and recipient sit at the same bank, disputes like those in Senator Warren's office report on Zelle scams and partial reimbursements land on a single institution, sharpening the reimbursement fight between banks and defrauded customers.
- Cross-border edge cases emerge outside the design brief — Venezuelan users adopting Zelle for dollar transactions shows demand flowing through the network in ways the seven owning banks never engineered for.
Third-order effects
- If the pattern holds, bank-consortium payment networks tend to fragment along institutional lines unless regulators or clearing infrastructure force true interoperability — cooperation among competitors producing parallel products, not a unified rail.
- The structural lesson favors either neutral networks or single-owner platforms: whoever controls the whole user relationship captures the network effect that a shared-brand model diffuses across dozens of banks.
The trend: Bank-backed P2P payment consortia are scaling volume through embedded distribution while quietly re-fragmenting into per-institution products, leaving true cross-bank interoperability unresolved.
