UK banks are advocating for a regulatory change that would exempt UK Treasury bills from the leverage ratio framework, a key capital adequacy measure under Basel III. The proposal, driven by leading institutions including Barclays and HSBC, seeks to allow banks to hold more short-dated government securities without triggering higher capital charges. This shift would effectively treat UK T-bills as risk-free for leverage purposes, similar to the treatment in other major economies. The leverage ratio currently requires banks to maintain a minimum ratio of Tier 1 capital to total exposure, typically set at 3% globally. Under current rules, even low-risk assets like UK government bills contribute to the denominator, increasing the effective capital burden. By exempting Treasury bills with maturities of up to one year, banks argue they could optimize balance sheets, improve liquidity buffers, and increase capacity for credit extension. If implemented, the exemption could reduce the effective leverage ratio exposure for UK banks by an estimated 15–20 basis points, depending on portfolio composition. This change may also enhance the attractiveness of UK gilts in international markets, potentially supporting lower yields on short-term debt and strengthening the pound’s appeal as a safe-haven currency. The UK10Y yield has already shown a 3-basis-point decline since the proposal was first discussed, reflecting market anticipation. The Treasury is expected to evaluate the proposal by Q3 2026, with feedback from the Bank of England and financial stability oversight bodies likely to shape the final outcome. The move could also influence related markets, including GBPUSD, which has seen a 0.3% uptick in recent weeks amid expectations of improved fiscal and monetary coordination.
