The UK runs the world's most mature open-banking regime, the longest-running instant rail in the developed world, and — since October 2024 — a mandatory reimbursement scheme for authorised push-payment fraud that sets a policy precedent no other major market has matched. The May 2026 Payments Forward Plan now sequences a PSR-into-FCA merger, a Faster Payments LIMA upgrade, and commercial VRP go-live, putting the entire stack into motion at once.
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.
Bank of England and HM Treasury completed the Digital Pound design phase in 2025 with no decision taken on issuance. Focus has shifted to wholesale DLT settlement and tokenized commercial bank money. A retail decision is not expected before 2027.
Instant payments
Faster Payments Service
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.
