ECB Supervisory Expectations — Prime Brokerage
Overview
The European Central Bank's (ECB) Supervisory Expectations for prime brokerage emerged primarily in the aftermath of the Archegos Capital Management collapse in March 2021, which caused over $10 billion in losses across global banks. The ECB's framework addresses client onboarding, counterparty credit risk (CCR) management, margining practices, and default management for banks engaged in prime brokerage activities.
The ECB published its supervisory expectations for prime brokerage services in August 2022, in its Supervision Newsletter. In October 2023 it followed with a broader report, "Sound practices in counterparty credit risk governance and management," which describes 43 sound practices it observed at the banks it reviewed. The ECB expects the banks it supervises to consider them, and says they go beyond compliance with regulatory requirements.

Who It Applies To
The ECB's supervisory expectations apply directly to significant institutions (SIs, the euro area banks under direct ECB supervision) that conduct prime brokerage activities. However, because many of these banks operate globally and interact with U.S. broker-dealers, the expectations have practical implications for any firm engaged in cross-border prime brokerage relationships.
Key Requirements
- Client onboarding due diligence: Banks must conduct thorough due diligence on prime brokerage clients, including assessment of the client's investment strategy, leverage, liquidity, and risk management capabilities.
- Counterparty credit risk governance: The ECB's 43 sound practices cover CCR identification, measurement, management, and reporting, with specific attention to concentrated exposures and wrong-way risk.
- Dynamic margining: Margin requirements must be calibrated to the client's actual risk profile, with the ability to increase requirements rapidly in response to changing market conditions or client behavior.
- Default management: Banks must maintain documented default management procedures, including close-out netting, collateral liquidation plans, and stress-tested contingency arrangements.
- Capital requirements: Banks must hold sufficient capital to cover prime brokerage risks.
- Stress testing: Regular stress testing of prime brokerage exposures under adverse scenarios, including client default, market dislocation, and liquidity stress.
