EXECUTIVE BRIEF · 10 SEPTEMBER 2026

Industry redraws the loss boundary for UK CCP resolution.

FIA and ISDA reject mutualising CCP operational and other non-default losses through default funds, warn that cash calls of up to three times member contributions can transmit liquidity stress across CCPs, and seek practical tear-up testing, member compensation and stronger cross-border execution.

EXECUTIVE TAKEAWAYS

01INT-2026-008 · LOSS OWNERSHIP ↓
Default funds should mutualise participant-default risk, not CCP operational or other non-default losses; the requested sequence puts CCP equity, parent support and other precommitted resources first.
023× DEFAULT FUND · LIQUIDITY ↓
Resolution cash calls of up to three times a member's default-fund contribution can become a correlated liquidity and procyclicality shock when several CCPs act together.
03TEAR-UP · OPERATING EVIDENCE ↓
Partial tear-up must be commercially reasonable and operationally tested, with hedge replacement, contagion, member compensation, No Creditor Worse Off valuation and third-country execution made explicit.

Member resources become an explicit design constraint in UK CCP resolution

FIA and ISDA support predictable resolution but oppose using mutualised default funds for CCP operational and other non-default losses. They want CCP equity, parent support and precommitted resources used before member cash calls, and warn that calls of up to three times default-fund contributions can create correlated liquidity stress across CCPs.

Why it matters

Resolution exposure now needs to be mapped as a member-level liquidity, capital, pricing and continuity problem. Legal authority is insufficient without identifiable loss ownership, reproducible No Creditor Worse Off valuations and executable hedge replacement after partial tear-up.

Likely business impact

Clearing-risk, treasury, legal and client-pricing teams should combine default-fund exposure, non-default-loss allocation, liquidity limits and hedge-replacement assumptions in one scenario framework. Daily or ad hoc reporting of initial margin, default funds, investments and called liquidity could become a resolution-data requirement.

What to watch

Priority of CCP equity and parent support in the end-2026 consultation
Any limit or cross-CCP liquidity condition on three-times-default-fund cash calls
Operational testing and disclosure for partial tear-up, member compensation and No Creditor Worse Off valuation
Third-country cooperation and recognition arrangements
