The Bank of England launches a consultation on new measures to strengthen the resilience of the UK gilt repo market, aiming to address systemic vulnerabilities highlighted by past crises and align with international regulatory trends.
The Bank of England has kicked off a substantial consultation through the release of a new discussion paper, which aims to strengthen the resilience of the UK gilt repo market—a key piece of the country’s financial setup. This effort was developed closely with the Financial Conduct Authority (FCA), and it also involved input from HM Treasury and the UK Debt Management Office. The paper basically puts forward two main reform options—one, to ramp up the central clearing of gilt repo transactions, and two, to set minimum haircuts or margin requirements on repos that aren’t cleared centrally. The consultation period runs until 28 November 2025, and they're encouraging responses to help shape what could happen next, which might involve more discussions or regulatory adjustments.
The reason behind considering these measures is linked to insights from the Bank’s System-wide Exploratory Scenario, which highlights how vulnerable the market can be during stressful times—something we saw quite clearly during the gilt market crisis in 2022. Back then, liquidity dried up pretty fast in the long-dated and index-linked gilts, mainly because liability-driven investors sold off assets, creating a domino effect across derivatives and repo markets. This led to higher transaction costs, bigger price gaps, and revealed how constrained the dealer sector could become. Those events really shone a light on the systemic risks that are baked into the current structure of the gilt repo market, making it clear that boosting its resilience is pretty important.
Now, looking at the first big idea in the paper—focusing on boosting central clearing—this actually aligns with global regulatory trends. For example, the US Securities and Exchange Commission (SEC) recently announced plans to make central clearing mandatory for most repo and cash Treasury transactions by the middle of 2027. Central clearing is generally seen as a way to reduce counterparty risk and make markets more transparent. The second idea tackles the risks tied to bilateral exposures—those direct agreements that, if not properly collateralized, can amplify shocks when markets are under stress. It proposes setting minimum haircuts or margins on non-centrally cleared repos, aiming to curb these kinds of risks.
Apart from these core measures, the Bank is also exploring other options, like better public and private disclosures about counterparty exposures. These could either supplement, or even serve instead of, the main proposals—they’d give market players a clearer picture of risks involved, helping them manage their exposures more effectively.
This whole initiative is part of a wider regulatory context. The Bank has published papers explaining how quantitative easing (QE) measures have historically impacted gilt repo market liquidity—generally speaking, QE has played a role in boosting liquidity and cutting borrowing costs, but during times of unexpected surge in liquidity demand, things can get tougher. Also, regulations introduced after the financial crisis—like leverage ratio rules—have had complex effects. While these measures help keep the financial system stable by limiting excessive leverage, they might also have inadvertently reduced how resilient the market is when it comes to liquidity, especially for gilts and repos. This adds a layer of complexity to balancing the risks and rewards for market makers.
Overall, the Bank's approach seems aimed at finding a middle ground—trying to reduce systemic risk without hampering the normal functioning of the market. They’re seeking detailed feedback from market participants on how these measures could be practically designed and implemented, including what costs or unintended side effects might crop up. That’s especially important because the gilt repo market underpins the liquidity of sterling and the broader stability of financial markets in the UK.
The Bank has framed this consultation as part of an ongoing dialogue, not just with other UK regulators but with market players too. Depending on what feedback they receive, further measures or reforms could follow, especially as the Bank keeps reassessing the evolving market conditions.

Developed in close consultation with the Financial Conduct Authority (FCA) and with input from HM Treasury and the UK Debt Management Office (DMO), the paper examines two primary options: increasing central clearing of gilt repo transactions and introducing minimum haircuts or margins on non-centrally cleared repos. These measures aim to reduce counterparty credit risk and mitigate systemic vulnerabilities. The paper also considers additional measures, such as enhanced public and private counterparty disclosures, to improve market resilience. The deadline for responses is 28 November 2025.

- https://www.bankofengland.co.uk/working-paper/2024/quantitative-easing-and-the-functioning-of-the-gilt-repo-market - This working paper assesses the impact of quantitative easing (QE) on the provisioning of liquidity and the pricing in the UK gilt repo market. The authors compare the behaviour of banks that received reserves injections via QE operations to other similar banks in terms of the amounts lent and pricing. They also investigate whether leverage ratio capital requirements affected the amounts of liquidity supplied by broker-dealers and the spreads they charged. The findings indicate that QE interventions can improve liquidity provision, and that their size determines how this is attained. QE can also reduce the cost of borrowing in the repo market unless it was associated with spikes in demand for liquidity. The study further indicates that the leverage ratio supports the provision of liquidity during stress, as it prompts banks to become less leveraged. However, the larger capital charge repo transactions attract under the leverage ratio requirement is reflected in their spreads.

The authors find that gilt repo liquidity worsened during the period when UK leverage ratio policy was announced, and that gilt liquidity worsened conditional on factors such as funding costs and inventory risk. They also find evidence that gilt repo liquidity has become less resilient. However, evidence from heterogeneity in dealer behaviour is inconclusive regarding a causal link between leverage ratio requirements and the reduction in market liquidity.

The study finds that selling pressure in gilt markets, due to deteriorating derivative and repo positions of liability-driven investors (LDI), led to evaporating market liquidity, especially in long-dated conventional gilts and index-linked gilts. The paper also highlights that transaction costs in bond markets quickly soared, particularly for smaller trades, for trades at smaller dealers, and for trades of non-LDI-PI investors. The aggregate dispersion of transaction prices more than doubled in a matter of days, and price dispersion across primary dealers remained significant throughout the crisis, suggesting tightened constraints on the intermediary sector.
