When global markets convulse, the quiet machinery that keeps government borrowing liquid suddenly matters a great deal. On 17 July the Bank of England republished remarks by its Deputy Governor for Financial Stability that leave little room for complacency. Sarah Breeden put it plainly: further engagement is essential because doing nothing is not an option.
The intervention draws directly on the July 2026 Financial Stability Report, which found that UK gilt and gilt repo markets held firm amid volatility triggered by the onset of fresh conflict in the Middle East. Yet the same document flagged persistent concerns. Leveraged borrowing by hedge funds in the repo market remains elevated. A small number of these funds account for the majority of net gilt repo borrowing. With net borrowing in the market running at around £200 billion, of which £85 billion comes from hedge funds, the concentration is unmistakable.
Breeden's analysis reaches back to a discussion paper the Bank issued in September 2025. That paper set out potential measures to strengthen resilience, chief among them greater central clearing of gilt repo trades and the introduction of minimum haircuts on transactions that remain outside central clearing. A feedback statement followed on 1 April 2026, summarising industry comments and mapping the path forward. The work will continue through the remainder of 2026, with further analysis due to inform decisions that cannot be rushed.
Rollover risks and crisis amplification
The vulnerabilities are not abstract. Past stress, including the 2022 liability-driven investment episode, showed how quickly repo financing can seize up. The Bank's own system-wide exploratory scenario exercise demonstrated that hedge fund activity can amplify shocks if funding costs spike or banks pull back. Short maturities and minimal haircuts heighten rollover risk precisely when markets need liquidity most.
Breeden does not understate the task.
Change of this kind will likely take years, not months. But the discussion must start now – because the prize is not just lower risk, but a stronger and more efficient market for all.Her tone reflects the measured realism that has long characterised the Bank's approach to financial stability. It rejects both complacency and the temptation to layer on expansive new bureaucracies. Instead it favours targeted, evidence-based adjustments that reinforce the frameworks on which savers, pension funds and the wider economy depend.
Such prudence matters. The gilt repo market sits at the heart of cash and collateral flows across the financial system. It transmits monetary policy and underpins the cash gilt market itself. When it functions smoothly, enterprise and long-term investment flourish. When it falters, confidence drains and the real economy feels the chill. By insisting on reform while markets remain relatively calm, the Bank demonstrates the value of independent institutions willing to act before the next storm arrives.
