Abstract. This piece argues that the most operationally important actor in structured finance — the corporate services provider (CSP) that administers the special purpose vehicle (SPV) — sits outside any prudential perimeter in the UK market (which this series principally covers), and that the market’s belief otherwise rests on a category error: treating registration for anti-money laundering (AML) and counter-terrorist financing (CTF) supervision as sufficient regulation of the firm.

In the UK, HM Treasury’s October 2025 decision to move AML/CTF supervision of trust and company service providers (TCSPs) to the Financial Conduct Authority (FCA), with the transfer, on the FCA’s published plan as at September 2026, not expected to begin before autumn 2028, is likely to be described as “the FCA now supervises TCSPs.” That will be true only of financial-crime compliance and not of the firm’s soundness. On the published proposals, the new regime will not examine operational resilience, financial standing, insurance adequacy or orderly substitution: the questions that decide whether a legally bankruptcy-remote vehicle can keep functioning.

Furthermore, in my experience the structured finance sector has sustained a culture of market insularity — at times described within debt capital markets as an “old boys’ club” — that is slow to change, slow to admit firms and people from outside the “established” network, and able to use procedural gatekeeping to shield repeat legacy relationships from professional scrutiny. Some of the sector’s older assumptions about who belongs in the room, in my view, still persist. Onboarding decisions wrapped in the vocabulary of “risk appetite” and “jurisdictional fit” can serve as administrative cover for excluding new entrants; informal gatekeeping is not merely a cultural failing, it is an unscrutinised operational vulnerability.

Building out the prudential-oversight pillar proposed in No. 02, I set out six structural issues and a five-element reform anchored in a professional-services regulatory model: a supervisor with a conduct and prudential mandate, mandatory professional indemnity insurance (PII) scaled to administered liabilities, a deal-level public register, fit-and-proper scrutiny of CSP ownership and control, and transaction-level continuity and governance requirements.

Who Should Read This and How

■ For Arrangers & Trustees: Read this piece as an operational stress-test. You are the parties who will operate the substitution mechanics when — not if — they are ever tested. Commission the drill before the event does. Ask your administrators for their insurance towers and continuity plans, and put the answers in the deal file. None of this requires legislation; the disclosure above can be a deal term tomorrow.

■ For Institutional Investors: Use this commentary as a pre-trade diligence prompt. Administrative continuity risk is currently treated as zero in the SPVs you hold. It is not zero. Ask for administrator concentration and insurance disclosure as a standard part of pre-trade diligence, and treat their absence as information. This paper should not be read as evidence that administrator failures are already causing defaults; it is a case that no one is positioned to find out.

■ For Regulators & Policymakers: Treat this piece as a case for closing a perimeter gap. The FCA’s new AML mandate is necessary and welcome, and it is not prudential supervision. Close the actual gap: a conduct and prudential regime for CSPs, with resilience standards, personal accountability and a deal-level public register. The 2028–2030 transition window is the moment to design it, before the market files TCSPs under supervised and stops asking. Formal rule-making would, of course, need empirical data and impact assessment beyond practitioner observation; the register proposed here is how that data gets created.

■ For Academics & Researchers: Use this paper as a source of testable hypotheses. five testable hypotheses are offered here: CSP market concentration at the SPV level; the historical incidence of administrator substitution events and their costs; the relationship between PII coverage levels and recovery outcomes; the incidence and stated grounds of declined onboarding requests; and how open the administrator, trustee and independent-director pools are to new entrants. The data is not public. That is itself a finding worth publishing.
