Lloyd's Sets Conditions for Broker-Originated Reinsurance Structures From January 2027: No Broker Ownership, a 19.99% Managing Agent Stake and a 10% Cap on a Broker's Treaty Portfolio

Lloyd's of London has set out the conditions under which brokers may route client reinsurance business into capital-backed underwriting vehicles at Lloyd's. The rules were issued in Market Bulletin Y5493 on October 16, 2026 and take effect on January 1, 2027. The details in this article come from an Insurance Business UK report dated October 23, 2026. The bulletin itself was not reviewed, and the report notes that some terms are not publicly defined, so the description below is limited to what the report says.

The background

The bulletin follows months of debate in the market about whether brokers should be allowed to place portfolios of their clients' reinsurance business into vehicles backed by capital market investors. At the Monte Carlo Rendez-Vous in September 2026, reports described a plan by Aon and Blackstone to route part of Aon's brokered reinsurance flow into a Blackstone-backed Lloyd's vehicle. According to the report, neither company has confirmed this publicly, so it is reported speculation and not an announced deal. Lloyd's framed its bulletin as conditions for operating, not a ban, which the report reads as a sign that Lloyd's sees legitimate demand for such structures.

The central concern is one of roles. A broker acts for the client who buys reinsurance, while an underwriter takes risk. If a broker also has a financial interest in the vehicle that takes the risk, the broker's advice to clients may be influenced by its own interest. The conditions are designed to limit that overlap.

The main requirements

Broker ownership. Brokers cannot own or capitalise these structures. The report says this addresses concerns that such arrangements blur the line between intermediary and underwriter.

Managing agent capital. The managing agent, the firm that runs a syndicate at Lloyd's, must hold a minimum participation of 19.99%. The report notes that this sits just below the 20% level at which Lloyd's and FCA rules treat a holder as having significant influence, which triggers additional approval. The aim is for the managing agent to have real exposure to the book it underwrites.

Concentration cap. Initially, no more than 10% of an individual broker's treaty portfolio may be placed into these structures. Lloyd's describes this as an initial appetite and may revise it. A treaty portfolio is a broker's book of treaty reinsurance placements, so the cap limits how much of a broker's business can flow into a single type of vehicle.

All-or-nothing cession. A cedant, the insurer buying reinsurance, must cede either all of its eligible portfolio with the broker to the structure or none of it. The report says this prevents cedants from moving only their better business and leaving weaker risks elsewhere, a practice sometimes called cherry-picking.

Obligations on managing agents and brokers

Managing agents must show strong reinsurance pricing skills, portfolio solutions expertise, and sufficient access to data to validate and challenge the broker's assumptions. Brokers must provide monthly data to the managing agents, including dashboards, exception reports and bind-level data, and must report quarterly to Lloyd's. Annual plans and mid-year changes need approval from the Lloyd's Corporation Performance Group.

Cedants must share in the operational and capital efficiencies the structure produces. The report calls this one of the framework's more direct consumer-protection measures, and says that its adequacy will depend on how those efficiencies are priced against running costs.

Exclusions and conditions

Certain business types are excluded: hybrid fronting carriers, managing general underwriters and legacy providers. Involvement of captives requires a prior submit arrangement, and structures cannot carry exposure to cyber war "type 4" language. The report does not define these terms further.

The performance backstop

If a structure has not reached at least 70% indexation by year three, Lloyd's and the managing agent must agree next steps, which may include winding up. The report notes that Lloyd's has not publicly defined the indexation metric in the summaries available. It advises prospective participants to seek clarification through the new entrant process before January 1, 2027. The framework runs alongside the existing new entrant approval process and ongoing oversight.

What to watch

Four points will matter in practice. First, whether any broker-backed vehicle applies under the new framework before the January start date. Second, whether the 10% cap is raised once Lloyd's has seen how the structures behave. Third, how the client dividend requirement is priced, since it determines whether clients gain anything. Fourth, how the 70% indexation test is defined, because it determines when a structure could be wound up.

Who is affected

The framework matters most to three groups. Brokers that have been considering such vehicles now know the limits on ownership and volume. Managing agents, which would run the underwriting, must decide whether a 19.99% participation and the data obligations are worth taking on. And cedants, the insurers buying reinsurance, are told they can expect to share in any efficiencies, but only if they commit their whole eligible portfolio with the broker. One practical point follows from the rules as reported: a cedant must commit everything before it knows how large its share of the efficiencies will be, because that depends on how the dividend is priced.

Limits
