It is the summer of 2026, and Threadneedle Street is doing two things at once. The Bank of England is drawing up plans to ease the capital buffer requirements that major UK lenders must hold — the cushions that, in a crunch, are supposed to absorb the shock before it reaches ordinary depositors. At the same time, the Bank's own Financial Policy Committee has been putting something uncomfortable on record: that AI-driven investment strategies and debt-fuelled asset plays are becoming a genuine concern for financial stability.
The FPC's position, reported by The Guardian on 7 July 2026, reflects a tension that has been simmering inside central banking circles for the better part of two years. Algorithmic trading, leveraged bets on AI-adjacent assets, and the speed at which capital moves through automated systems have all sharpened the committee's attention. The worry is not that any single institution is overexposed — it is that the system as a whole is moving faster than the oversight mechanisms designed to catch it.
Against that backdrop, the plan to reduce capital requirements looks, to some observers, like loosening the brakes on a car whose speedometer is already reading high. The Bank's counterargument is straightforward: tighter buffers restrict lending, and restricted lending does its own kind of damage to an economy that could use the liquidity. The two positions are not necessarily incompatible, but the optics are difficult.
For the high street banks that stand to benefit — Barclays, NatWest, Lloyds, and their peers — the practical effect of lower capital requirements is room to deploy more capital into mortgages, business loans, and, yes, the kinds of complex financial products the FPC has just flagged as a concern. The FPC is expected to set out its revised framework in detail in the coming weeks.
