The world's largest card market remains stubbornly fragmented on rails: FedNow, RTP, Zelle and Nacha ACH compete where most peers run a single national instant scheme. Interchange revenue underwrites a rewards arms race that is now at structural risk from the 2024 CFPB §1033 open-banking rule and the GENIUS Act stablecoin framework, which entered OCC and Treasury rule-making during early 2026.
Tab 03
Rails & infrastructure
The instant rail, the RTGS spine, the card switch, the direct-debit scheme, and the country's CBDC stance. Each rail is reported with operator, launch year, and 2024 flow so the relative scale across rails is readable at a glance.
CBDC status is deliberately granular: live, pilot, preparation, live stalled, and sceptical, no pilot are different things.
A January 2025 executive order banned federal development of a retail CBDC. The Federal Reserve continues wholesale research (Project Hamilton with MIT DCI was paused in 2022) but no retail pilot is planned. Stablecoins under the GENIUS Act are effectively the US policy answer to a digital-dollar question.
Instant payments
FedNow Service + RTP (The Clearing House) + Zelle (Early Warning Services)
The instant leg typically carries the vast majority of retail consumer flow in modern payment systems — and sits in direct tension with card networks and wallets for the same transactions.

RTGS
Real-time gross settlement
The RTGS spine clears high-value interbank flow — including the settlement of the instant-rail cycles and card-network net positions. Transaction count is modest; cleared value is enormous.
