We won’t copy UST clearing mandate wholesale in UK – BoE
The Bank of England will not adopt the U.S. clearing mandate for government bonds in the UK indiscriminately, according to Pelagia Neocleous, a senior manager for financial stability strategy and risk at the institution. Neocleous also confirmed that any minimum repo haircuts for bilateral bond trades will be calculated at the portfolio level, not on a transaction-by-transaction basis.
Neocleous’ remarks, made during a public discussion on regulatory approaches, signal a deliberate departure from direct replication of U.S. policies. The U.S. requirement mandates that certain government bond transactions be cleared through central counterparties, a process aimed at reducing systemic risk. The BoE’s decision reflects a focus on tailored regulatory frameworks suited to the UK’s financial infrastructure.
The portfolio-level haircut calculation introduces a nuanced approach to risk management. Instead of applying uniform haircut requirements to each trade, firms would assess risks across their entire bond portfolios. This method could reduce administrative burdens while maintaining safeguards against market volatility.
Why does this matter?
The BoE’s stance underscores a broader trend among regulators to balance risk mitigation with market efficiency. By avoiding a direct copy of the U.S. mandate, the UK aims to preserve flexibility in its financial systems. This approach may also align with the BoE’s ongoing efforts to support market liquidity, particularly in the context of post-Brexit regulatory adjustments.

What happens next?
The BoE is likely to continue refining its regulatory stance through consultations with industry stakeholders. Market participants may push for further clarity on how portfolio-level haircuts will be implemented. Analysts suggest that the central bank could issue additional guidelines later in 2024, though no formal timeline has been announced.
How does this compare to other markets?
Unlike the U.S., where clearing mandates apply broadly to government bonds, the UK’s approach appears more selective. Regulatory bodies in the European Union have also adopted hybrid models, blending mandatory clearing with exemptions for certain trades. The BoE’s decision may reflect a cautious response to the unique characteristics of the UK’s bond market.
