SATURDAY EDITION · Two new events and one materially changed implementation milestone since the 30 September cut-off.

EXECUTIVE TAKEAWAYS

  1. 01RELATES TO · UK–US ACCESS ↓

    CFTC relief keeps established UK venues and substituted-compliance routes usable, but only until superseding orders or 31 December 2027.

  2. 02RELATES TO · T+2 LIQUIDITY ↓

    Eurex now converts T+2 currency settlement exposure above €10 million into an intraday collateral call rather than an end-of-day observation.

  3. 03RELATES TO · UNO MIGRATION ↓

    The first Project UNO production move is 24 October; source-account inventory and report reconciliation are weekend controls, not administrative follow-up.

CFTC extends UK substituted-compliance and venue relief through 2027

CFTC Staff Letter 26-28 preserves substituted compliance for registered swap dealers using incorporated UK law and registration relief for listed UK MTFs and OTFs. It expires on superseding UK comparability or exemptive action, or 31 December 2027.

PRIMARY SOURCECFTC — UK derivatives relief extension ↗PRIMARY SOURCECFTC — Staff Letter 26-28 ↗

Why it matters

Existing cross-border execution routes avoid an immediate Brexit cliff, but the relief is temporary and does not remove Part 50 clearing requirements.

Likely business impact

Keep UK venue and dealer mappings active; retain FCM/DCO controls for customer clearing; track the replacement-order trigger rather than treating 2027 as an unconditional end date.

What to watch

  • UK comparability and exemptive orders
  • Changes to the listed MTF/OTF population
  • FCM and registered-DCO routing for customer positions

Eurex activates intraday supplementary margin for T+2 settlement currencies

From 1 October, aggregate debit payments above €10 million equivalent across AUD, DKK, NOK, NZD, SEK and JPY can generate supplementary margin for ETD premiums, variation margin and cash settlements. The charge is intraday and released at end of day.

PRIMARY SOURCEEurex Clearing — Supplementary margin for T+2 currencies ↗

Why it matters

A two-day cash-settlement gap now has a quantified liquidity consequence. Local bank holidays can repeat calls across consecutive days.

Likely business impact

Model currency-level debit peaks, collateral headroom and holiday sequences; verify CLM/SUMS booking and the event-driven intraday-call threshold in production.

What to watch

  • First actual calls and released amounts
  • Currency-list changes
  • Consecutive-day calls around local holidays

Eurex dates the first Project UNO GC Pooling production migration for 24 October

On 24 October, open GC Pooling and GC Pooling Re-Use exposures settling on 6-series accounts will move to CBL accounts, including Re-Use collateral. The source accounts cease to be eligible after migration.

PRIMARY SOURCEEurex Clearing — Project UNO GC Pooling migration reminder ↗

Why it matters

The broad 2027 collateral-account programme now has a near-term production weekend with explicit inventory, transfer-failure and reconciliation controls.

Likely business impact

Hold sufficient eligible inventory on source accounts, prepare a fallback if CmaX cannot transfer an allocated ISIN, and reconcile CE860, CE880 and TC850 reports on migration day.

What to watch

  • 24 October completion evidence
  • Failed or residual ISIN transfers
  • Post-migration settlement and Re-Use exceptions
