BoE Gilt Repo Clearing: Market Pushback on Mandatory Approach

The Bank of England is facing pushback from market participants over proposals to introduce mandatory clearing for gilt repo transactions, according to a report from Risk.net published February 12, 2026. Concerns center on the potential for increased costs and limited netting benefits compared to other jurisdictions.

The BoE initially floated the idea in a discussion paper released in September 2025, outlining potential reforms to the UK gilt repo market. The proposals aim to enhance the resilience of the market, particularly during periods of stress and build on similar moves in the US Treasury market. However, industry officials are warning against a “one-size-fits-all” approach.

The core of the debate revolves around central clearing. Currently, a significant portion of gilt repo transactions are cleared bilaterally. Mandatory clearing would require these transactions to be processed through a central counterparty (CCP), introducing additional layers of cost and complexity. While central clearing is often touted for reducing systemic risk, market participants argue that the benefits may not outweigh the costs in the gilt repo market.

A key concern is the limited netting benefits. Netting allows participants to offset multiple trades, reducing the overall amount of collateral required. However, the structure of the gilt repo market, and the specific types of participants involved, may limit the effectiveness of netting, diminishing the risk reduction benefits of central clearing. This contrasts with experiences in other markets where netting has proven more impactful.

The Bank of England’s interest in reforming the gilt repo market stems from a broader focus on financial stability. As highlighted in the September discussion paper, resilient government bond markets are crucial for financing government activity and serving as benchmarks for other financial instruments. The gilt repo market plays a vital role in facilitating the flow of cash and gilts, and providing funding for leveraged strategies. The BoE, in conjunction with the Financial Conduct Authority (FCA), HM Treasury, and the UK Debt Management Office (DMO), is seeking to identify and mitigate vulnerabilities that could impact the market during times of stress.

The discussion paper also explores other potential measures to bolster the market’s resilience, including greater central clearing and minimum haircuts in non-centrally cleared transactions. Haircuts refer to the difference between the market value of the security and the amount of cash lent against it. Increasing haircuts would require participants to provide more collateral, potentially reducing leverage and increasing market stability.

The BoE’s consultation period for the discussion paper closed on November 28, 2025, with responses to be sent to GiltreporesilienceDP@bankofengland.co.uk. The feedback received will be crucial in shaping the final policy decisions. The market’s concerns, as reported by Risk.net, suggest that the BoE may need to carefully consider a more nuanced approach than a blanket mandatory clearing regime.

The debate over mandatory clearing also highlights the broader tension between regulatory efforts to enhance financial stability and the potential for increased costs and reduced efficiency in financial markets. Finding the right balance is a key challenge for policymakers as they navigate an increasingly complex financial landscape.
