UK banks have pledged about £17.8 billion in higher risk, less liquid assets to the Bank of England. In exchange, they receive central bank reserves.
This amount has more than doubled from £8.7 billion a year ago. On 18 August 2026, banks pledged £1.9 billion of this collateral type in a single auction. That was the biggest weekly total since March 2020.
These numbers sound alarming at first. But they do not signal a new banking crisis. The rise connects to a planned shift in how banks access cash as the Bank of England continues to reduce its bond holdings.
What Are Banks Pledging to the Bank of England?
Banks use the Bank of England’s Indexed Long Term Repo facility, known as ILTR, to access this funding.
Under this system, banks offer eligible assets as collateral. In return, they receive central bank reserves.
The £17.8 billion figure covers Level C collateral. This is the least liquid category the facility accepts. It can include:
- Vehicle leases
- Consumer credit
- Mortgage-backed securities
- Securitised business loan portfolios
These assets take longer to sell than government bonds or other highly liquid securities.
The Bank of England manages this added risk through stricter valuations, higher borrowing costs, and larger haircuts. A haircut means the Bank lends less than the full value of the collateral offered.
Why Has ILTR Usage Grown So Fast?
The main driver is a structural shift in the UK banking system.
During quantitative easing, the Bank of England created large reserves by buying bonds. Quantitative tightening now reverses part of that process.
As reserves shrink, commercial banks need other ways to maintain the liquidity they require. The Bank of England expects facilities like ILTR to play a bigger role in supplying those reserves going forward.
This explains why total ILTR use has climbed sharply. Level C assets have held steady at roughly 20% to 25% of ILTR collateral, even as the overall amount pledged has grown. The increase reflects wider use of the facility, not a spike in risk from any single asset type.
Why Are Financial Stability Concerns Rising?
The debate goes beyond how much banks are borrowing. The bigger question is which asset types central banks should accept as collateral.
The European Central Bank has tightened its rules around comparable collateral types. The Bank of England still accepts a wider range of less liquid assets and manages its exposure through pricing and haircuts instead.
Some critics worry that broad collateral rules could shape how banks approach higher risk lending and securitised credit. Still, higher use of Level C assets does not on its own point to financial distress among UK banks.
What Does This Mean for UK Businesses?
For business owners and directors, the main message is simple: do not panic.
The £17.8 billion figure reflects a major shift in how liquidity moves through the banking system. It is not clear evidence of a banking crisis.
That said, businesses should watch broader changes in bank funding, lender appetite, and access to working capital as the UK moves further away from the quantitative easing era.
Directors should take three steps now:
- Keep cash flow forecasts current, supported by accurate bookkeeping throughout the year
- Understand how much the business relies on external finance
- Review funding options before pressure builds, not after, ideally with support from a virtual finance director
