August, covering 1 to 31 August 2026, was a quiet month, though not an empty one. EIOPA refreshed two production DPM databases with their version numbers unchanged, the CSSF issued new versions of four filing templates, and BaFin fined both ends of a chain over a key information document that was never published. The commitments with firm dates came from the UK: transaction reporting from April 2028, T+1 settlement from October 2027.

Solvency II, EIOPA and the reporting data models

EIOPA refreshed the DPM databases without moving a version number - on 12 August 2026 EIOPA republished the Solvency II DPM database (2.10.0) and the IRRD database (2.11.0) with new YDimVal and ZDimVal dimensional values, the unified database following on 14 August (EIOPA DPM and XBRL). Because the version numbers did not move, a chain that tracks versions has nothing to react to; both databases need downloading again and the validations re-running.

The DPM Alliance is consulting on the metamodel underneath all of it - the EBA, ECB and EIOPA opened a consultation on 31 July 2026 on DPM standard 2.1, which adds "enhanced metadata versioning" and extends the metamodel "to host logical data models" (EBA). This is the layer behind every future EIOPA taxonomy, so mapping and validation tooling is in scope; firms carrying naming or versioning difficulties are advised to raise them before the consultation closes on 30 September 2026.

PRIIPs and enforcement

BaFin fined both ends of one chain for a missing KID - on 20 August 2026 BaFin published two fines, both final on 30 July, over one profit-participation certificate offered to retail investors from July 2025: €15,000 against the distributor under PRIIPs Article 13(1) with Article 14, and €9,000 against the issuing vehicle as manufacturer under Article 5(1) (distributor, manufacturer). A single missing document produced two separate breaches along one chain, and the issuing vehicle was treated as a full PRIIPs manufacturer. The penalties are small; the notices carry the firm's name.

Funds - Luxembourg and the EU

Four CSSF filing templates moved to new versions - the sub-fund approval questionnaire moved to Version 1.5 on 4 August 2026, the AIFMD Article 33(2)/(3) notification letter to Version 3.2 on 21 August, and the UCITS and AIF initial/update forms were reissued on 25 August (questionnaire, Article 33 letter, UCITS form, AIF form). The pages carry version numbers and dates without describing what changed, so in our view each form is best taken from the CSSF library at the time of filing.

ESMA's MMF stress-test consultation closed, and the change is procedural - it ran from 5 May to 6 August 2026 and proposes replacing annual amendments to Section 5 of the Guidelines with an annual web publication of the parameters (ESMA). What is stress-tested does not change, so this is no model rebuild. What changes is timing: in our reading, a Guidelines amendment passes through the EU translation cycle before it applies where a web publication does not, so parameters bind sooner and the page needs watching each year. A final report is expected in H2 2026.

Taxonomy Article 8 KPI advice moved towards simplification - ESMA's consultation on technical advice for selected KPIs under the Taxonomy Disclosures Delegated Act ran from 1 July to 12 August 2026, centred on the OpEx KPI and its possible voluntary use (ESMA). A voluntary treatment would relieve the metric hardest to source from investees, so that part of the year-end KPI build is worth leaving open until ESMA's advice, due by end-October 2026.

Derivatives and margin

The ESAs proposed extending initial-margin relief to legacy contracts - a joint final report of 3 August 2026 proposes draft RTS amending Delegated Regulation (EU) 2016/2251 so the Article 28(1) initial-margin exemption below the €8bn threshold would cover existing contracts, not only new ones (EBA). It would remove an asymmetry that splits one book, but it sits with the European Commission for endorsement, so it remains a watch item for collateral operations near the threshold.

ESMA is consulting on clearing at recognised third-country CCPs - a consultation of 18 August 2026 proposes technical standards under EMIR Article 7d, inserted by Regulation (EU) 2024/2987, for annual reporting by clearing members and clients on their activity at recognised third-country CCPs (ESMA). ESMA says the design seeks to "maximise the reuse of information already available through existing reporting channels", so mature EMIR reporting should mean a smaller increment. Whether insurers and fund managers are captured as "clients" is unsettled, and firms clearing at such a CCP should read the scope section before 12 October 2026.

UK

The FCA finalised transaction reporting reform, applying from 2028 - PS26/15 of 3 August 2026 cuts reportable fields from 65 to 52, removes roughly 7 million instruments tradeable only on EU venues, takes FX derivatives out of scope for over 400 firms, and cuts the default back-reporting period from five years to three; the FCA expects savings of more than £100m a year (PS26/15). Mappings, validations and reference-data sourcing all move, and the three-year window changes the economics of a remediation backlog. In our experience that work goes better scoped early, well ahead of the 3 April 2028 application date.

The FCA opened its equity transparency package - CP26/30 and CP26/31, both of 31 July 2026, propose changes to equity transparency, systematic-internaliser trade reporting and venue resilience, plus a framework for a UK equity consolidated tape (CP26/30, press release). The SI proposals are what would touch existing trade-reporting configurations, while tape procurement has not begun, so firms with UK chains will get more from responding on the SI mechanics. Both close on 16 October 2026.

The UK's T+1 date is fixed for October 2027 - an FCA blog of 13 August 2026 calls "the UK's move to a T+1 securities settlement cycle on 11 October 2027 ... a fundamental shift in how securities transactions are settled", and points to the Accelerated Settlement Taskforce's recommendations on same-day allocation and confirmation and on settlement instructions (FCA). Compression to the trade date is where manual and exception-based processing stops scaling, and cross-border books carry mismatches against markets on longer cycles, which is work worth mapping before go-live. The FCA reports a December 2026 milestone for the Taskforce's critical recommendations.

FRAME and the UK AIFM regime - the FCA's CP26/26 and CP26/28 of 14 July 2026 propose a new fund reporting framework and the end of AIFMD Annex IV reporting; please refer to our article of 27 July, UK fund reporting reform: FRAME and divergence from the EU.

Switzerland

FINMA's market report shows divergence under a stronger headline - the Insurance market report 2025 of 20 August 2026 puts the market-wide SST ratio at 254%, up 8 points, profits up 135.8% to CHF 24.4bn and equity up 15% to CHF 90.7bn (FINMA). Underneath it, reinsurers' SST ratio fell 4 points to 231% while their profits multiplied, and life insurers' equity fell 4% as profits rose 10.2%. A result driven by investment returns and a capital restructuring does not, in our view, improve the ratio between risk-bearing capital and target capital.

On our radar in the coming months

  • 30 September 2026 - the DPM Alliance consultation on DPM standard 2.1 closes.
  • 18 September and 22 October 2026 - the discussion chapters of FCA CP26/28 close, then FRAME (CP26/26) and CP26/28 themselves; the FCA extended both papers in late August.
  • 12 October 2026 - ESMA's third-country CCP reporting consultation closes.
  • End of October 2026 - ESMA delivers its Taxonomy Article 8 KPI advice to the Commission.
  • December 2026 - the Taskforce's critical recommendations fall due ahead of T+1, with ESMA's next MMF calibration.
  • H2 2026 - ESMA's 2026 forward planning table schedules the AIFMD and UCITS RTS and ITS on reporting, the last chance to shape the templates before they are drafted by April 2027. See our article of 8 May.

Two of this month's items, the DPM republish and the CSSF forms, arrived without release notes, which is what makes them easy to miss. To talk through what either means for your chain, please get in touch with our team.
