European financial regulators have completed rules forcing major banks and investment firms to maintain active clearing accounts within the European Union, part of a broader effort to reduce the bloc's reliance on UK-based clearing houses following Brexit.

ESMA Finalizes Rules for EU Banks' Mandatory Clearing Accounts

The European Securities and Markets Authority (ESMA) published its final technical standards Thursday, detailing how financial institutions must comply with the Active Account Requirement that takes effect later this year. The rules apply to firms clearing more than €3 billion worth of euro-denominated interest rate derivatives and Polish zloty contracts.

Banks subject to the new requirements will need to demonstrate their EU clearing accounts can handle a threefold increase in trading volumes within short notice. They must also clear representative trades across different contract types and maturities to prove the accounts remain functional rather than dormant.

The regulations target institutions heavily exposed to LCH Ltd and ICE Clear Europe, two London-based clearing houses that handle the bulk of European derivatives trading. EU officials worry this concentration creates financial stability risks if access to these services gets disrupted.

"The active account requirement appropriately contributes to the overarching objective of reducing the excessive exposures to substantially systemic clearing services provided by third-country CCPs," ESMA stated in its 216-page final report.

Banks Get Six-Month Window to Comply with EU Clearing Requirements

Financial firms will have six months to establish compliant accounts once they breach the €3 billion threshold. Those already clearing at least 85% of their relevant derivatives within the EU get exempted from the operational requirements, though they still must maintain the accounts.

The rules include a scaled approach based on trading volumes. Institutions with less than €6 billion in outstanding positions face lighter requirements, while those above €100 billion must meet stricter compliance timelines and reporting obligations.

Banks will need to conduct annual stress tests proving their accounts can absorb large transaction flows. They must also designate staff responsible for maintaining clearing operations and report their compliance status to national regulators every six months.

The requirements cover three specific categories: over-the-counter interest rate derivatives in euros, and short-term interest rate derivatives. ESMA based these selections on its assessment of which clearing services pose substantial systemic risks to EU financial stability.

Industry Concerns

Industry groups had raised concerns about implementation costs and the burden of maintaining multiple clearing relationships. Some argued the requirements could force unnecessary trading purely for compliance purposes.

ESMA addressed these concerns by simplifying reporting requirements and allowing flexibility in how firms demonstrate account representativeness. The regulator removed some granular data collection initially proposed after industry feedback.

The European Commission now has three months to adopt the technical standards, which would then require approval from the European Parliament and Council. The rules represent a key component of the EU's post-Brexit strategy to strengthen its financial market infrastructure and reduce dependency on UK-based services.
