Bank of England plots to loosen bank leverage rules — potentially unlocking £150B for gilts (but risks overexposure)

The Bank of England (BoE) outlined a plan to ease bank leverage rules, potentially unlocking around £150 billion for gilt markets. The goal is clear: more capital flexibility could boost gilt demand and push yields lower.

Still, the trade-off matters. Easing constraints may also increase the system’s exposure to gilts, raising the risk of concentration and echoing vulnerabilities seen in past financial cycles. For fixed-income investors, the BoE’s signal could reshape liquidity, pricing, and the UK interest-rate outlook.

The Bank of England (BoE) has laid out a plan to make leverage rules less restrictive for banks. The move could increase appetite for gilts—UK government bonds—potentially unlocking roughly £150 billion in demand. In theory, stronger flows into gilts would improve market liquidity and help lower yields.

At the same time, the BoE appears mindful of the downside. By allowing more balance-sheet capacity, the financial system could become more exposed to the gilt market itself. In other words, the potential for yield support and demand is paired with the risk of overexposure—an issue the industry has faced in earlier periods of stress.
