Reporting harmonisation taskforce: the wholesale data reckoning begins

The FCA and Bank of England have appointed members to a Transaction and Post-trade Reporting Harmonisation Taskforce covering UK MiFIR, UK EMIR and UK SFTR, structured across three working groups: Policy, Strategy and Architecture (FCA). The membership reads as a who's who of the wholesale plumbing: Barclays, Citigroup, J.P. Morgan, Morgan Stanley, Goldman Sachs, BlackRock, Vanguard, Man Group, Baillie Gifford, Citadel, Deutsche Bank, RBC, TP ICAP, Bloomberg, DTCC and ISDA all have seats (FCA). That composition tells you everything about how the regulators intend to run this: not as a consultation exercise bolted onto existing rulebooks, but as a co-design of the reporting architecture itself.

The timing matters. On 20 July the PRA fined HDI Global SE £4,165,000 for inaccurate reporting of FSCS Liabilities and Fee Tariff data between August 2021 and August 2024, including errors introduced during purported remediation (Bank of England). Gareth Truran, Executive Director for Insurance Supervision, was explicit: "Firms must maintain effective systems and controls to ensure the integrity of data submissions. This is fundamental to achieving the PRA's safety and soundness objective" (Bank of England). Read alongside the taskforce announcement, the direction of travel is unambiguous. Regulators want data they can trust, and they are prepared to punish firms whose controls do not deliver it while simultaneously rebuilding the framework those firms report into.

What senior leaders should read into the structure

The three-group design is the tell. A Policy group chaired jointly by the FCA's Helen Packard and the Bank's Julia Giese will decide the substance (FCA). A separate Strategy group, chaired by the FCA's Dominic Holland and the Bank's Nicholas Butt, sits alongside it, with buy-side compliance heads from BlackRock, Citadel and Capula in the room (FCA). An Architecture group signals that the technical stack, identifiers, data standards, submission pipes, is being treated as a first-order design question rather than an implementation detail. Firms whose reporting operations sit in the compliance basement, staffed by contractors reconciling breaks after the fact, are structurally exposed. Those with reporting engineering embedded in the trading and post-trade stack will find the coming rewrites cheaper and faster.

For boards, there are two immediate positioning questions. First, who owns transaction and post-trade reporting internally, and does that owner have a seat at the table when trading technology and data architecture decisions are made. The HDI Global case turned on "a lack of clear accountability, internal oversight and challenge" (Bank of England), and that finding will echo through supervisory conversations across regimes, not just prudential ones. Second, how is the firm engaging with the taskforce output. Firms without a direct seat, and most do not have one, will need to work through their trade associations, AFME, AIMA, ISDA, ISLA, FIA, all of which are represented (FCA), or risk having architectural decisions taken without their input.

Harmonisation sounds like relief. In practice it means every in-scope firm will rebuild its reporting once, under regulators who have just demonstrated they will fine seven figures for getting the current version wrong.
