HM Treasury has made the Securitisation (Overseas STS Equivalence) (European Union, Iceland, Liechtenstein and Norway) Regulations 2026, with effect from 11.00 p.m. on 30 June 2026. The instrument was made on 20 May 2026, laid before Parliament on 21 May 2026, and applies across England and Wales, Scotland and Northern Ireland. According to the statutory instrument published on legislation.gov.uk, the Regulations were signed by Gen Kitchen and Stephen Morgan as two of the Lords Commissioners of His Majesty's Treasury. The measure is tightly drawn and designates named jurisdictions for a specific category of securitisation rather than reopening the wider UK framework.
The designated category is narrower than a general recognition of all overseas securitisations. Regulation 2 applies only to securitisations, other than synthetic securitisations, that are treated as simple, transparent and standardised under the law and practice of the European Union, Iceland, Liechtenstein or Norway. In plain English, STS is the shorthand used in the rulebook for 'simple, transparent and standardised' transactions. The new instrument does not create a fresh UK STS regime. Instead, it decides that certain overseas transactions from those jurisdictions can be recognised within the UK system as overseas STS.
The Explanatory Note sets out the legal consequence with more precision. Once the designation takes effect, the in-scope transactions fall within the definition of 'overseas STS securitisation' in regulation 12(2) of the Securitisation Regulations 2024 and may therefore be described as 'STS' or 'simple, transparent and standardised' for the purposes of regulation 12(1). That means the immediate change is about legal status and market description in the UK. For firms involved in cross-border issuance, investment and distribution, qualifying transactions from the designated jurisdictions can carry the STS description in the UK because they now sit inside the overseas STS definition in UK rules.
The Treasury's reasoning is recorded in the operative text of the instrument. Acting under regulation 13(1) of the Securitisation Regulations 2024, ministers state that they have had regard to the matters listed in regulation 13(3) and are satisfied that the law and practice applicable across the European Union, Iceland, Liechtenstein and Norway has equivalent effect, taken as a whole, to applicable UK law. The instrument also states that the Treasury considered whether the Financial Conduct Authority and the Prudential Regulation Authority had established effective co-operation arrangements with the relevant competent authorities. That is an important part of the equivalence test, because the decision rests on both regulatory outcomes and supervisory co-ordination.
The exclusion of synthetic securitisations is one of the most important limits in the measure. The Regulations do not provide blanket recognition to every transaction that may be treated as STS overseas, and firms will still need to assess whether a structure is in scope before describing it as overseas STS for UK purposes. For compliance and legal teams, the test remains practical. A transaction will need to be non-synthetic and already treated as STS under the law and practice of the European Union, Iceland, Liechtenstein or Norway before the UK designation becomes available.
The policy effect is therefore measured rather than expansive. HM Treasury is recognising specified overseas regimes as equivalent for a defined subset of securitisations, not rewriting the domestic UK criteria or changing the treatment of structures outside the designation. That narrow approach is reflected in the impact material. The Explanatory Note says no full impact assessment has been produced because no significant impact on the private, voluntary or public sector is foreseen, although a de minimis impact assessment has been published alongside the Regulations.
In market terms, the change should reduce uncertainty over how qualifying transactions originating in the European Union, Iceland, Liechtenstein and Norway are described when they enter a UK regulatory context. It does not alter the domestic tests for UK STS transactions, and it does not extend recognition to synthetic structures. The Regulations sit within the framework set by S.I. 2024/102, as amended by S.I. 2024/705 and S.I. 2024/1202. For regulated firms, the immediate implementation task before 30 June 2026 is straightforward: transaction documentation, labelling and internal controls will need to match the exact scope of the new designation from the moment the instrument comes into force.
