The UK government plans to relax the ring-fencing rules that have kept retail banking separated from riskier investment banking since the 2008 financial crisis. The changes, expected next week as part of the Enhancing Financial Services Bill, would reduce compliance costs for major lenders like Lloyds, NatWest, HSBC, Barclays, and Santander UK.
The biggest operational shift: banks can now share essential back-office functions-IT systems, compliance teams, infrastructure-across their ring-fenced and non-ring-fenced entities. This eliminates expensive parallel setups.
Ring-fencing was a signature response to the financial crisis, implemented following recommendations from the Independent Commission on Banking, led by Sir John Vickers. The rules took full effect in 2019 for banks with £35 billion in core deposits.
Lloyds and NatWest, as predominantly domestic lenders, stand to benefit most directly. Their compliance costs have hit margins on mortgages and business loans. For HSBC and Barclays, sharing infrastructure across divisions could unlock significant efficiencies.
The £35 billion threshold means only the biggest players gain. Mid-tier and challenger banks, never required to ring-fence, won't see cost reductions while their largest competitors get leaner.
