HM Treasury’s payments overhaul: what the Modernising Payment Services Regulation consultation means for UK operators
Situation
HM Treasury published Modernising Payment Services Regulation on 14 July 2026, its consultation on rebuilding the UK’s payments regulatory framework. The consultation runs twelve weeks and closes on 6 October 2026. It sits within the government’s National Payments Vision programme and was timed to coincide with the Chancellor’s Mansion House speech, positioning it as a growth measure rather than a routine technical update.
The proposal has three structural planks. First, a shift from legislation to FCA rulemaking: most of the detailed requirements currently sitting in the Payment Services Regulations 2017 and the Electronic Money Regulations 2011 would move into the FCA Handbook, leaving only the payments perimeter, key definitions and core statutory protections in law. Second, a single regulatory framework spanning fiat money, tokenised deposits and regulated stablecoins, so the same permissions could in principle cover all three depending on issuer status. Third, explicit provision for agentic AI payments, including a review of authentication, consent and liability rules where an AI agent initiates a transaction on a customer’s behalf.
Why it matters
This is the first ground-up rebuild of UK payments regulation since the 2017 PSRs, and the direction of travel — moving technical detail out of statute and into a more agile FCA rulebook — changes how future rule changes get made. Once implemented, amendments that currently require secondary legislation could be made through FCA consultation instead, which is faster for the regulator but also means the rules an operator builds against can move with less parliamentary friction than before.
For SMB-facing fintechs and finance functions, the more immediate exposure is the tokenisation and stablecoin provisions. Treasury is proposing that UK-issued qualifying stablecoins be treated as money-like instruments within the same permissions framework as conventional payments, which would lower the regulatory distance between a stablecoin-settled product and a conventional one. Firms currently treating stablecoin rails as a separate, lower-priority workstream should treat that assumption as time-limited.
The agentic payments provisions are the least developed part of the paper and the part most worth an early response. Treasury is asking open questions rather than proposing settled rules on how authentication and liability should work when an AI agent — not a human — authorises a payment. Firms already building or piloting agentic checkout, procurement or treasury tools have a genuine opportunity to shape a nascent liability model, which is a materially different position from responding after the rules are set.
There is also a governance signal buried in the consultation: Treasury is seeking views on extending senior manager accountability further into payment and e-money institutions, citing the growth in both the sector and its financial crime exposure. Any SMB operating as a payment or e-money institution — rather than merely using one — should read this as an early marker for personal accountability requirements, not just firm-level ones.
What is not yet settled
Treasury has not committed to a position on how much of the current framework moves to FCA rules versus what stays in statute; that split is the central open question of the consultation, not a proposal being confirmed. Implementation is planned through secondary legislation, with detail on timing to follow after the consultation closes. The indicative aspiration in the Payments Forward Plan is for Treasury’s response in Q4 2026, but no firm implementation date exists yet. Firms should not plan around specific compliance dates until the response is published.
Recommended actions
Now – September 2026 Assess exposure across three areas: tokenised or stablecoin-adjacent product plans, any agentic payment or AI-initiated transaction functionality (live or piloted), and current status as a payment or e-money institution versus a user of one.
By late September 2026 Decide whether to submit a consultation response. The agentic payments questions are open enough that an early, specific submission carries more influence than a response after policy positions harden.
6 October 2026 Consultation closes. Treat this as the last point at which operator input can shape the framework before Treasury moves to drafting its response.
Q4 2026 (indicative) Watch for Treasury’s consultation response, which should confirm the legislation-to-FCA-rules split and give a first indication of implementation timing.
