Regional bank deposit outflow and liquidity buffer choices

Current net outflows are £4.2bn / 1.18 = £3.559bn. At a 115% floor, required HQLA is 1.15 × £3.559bn = £4.093bn, so the bank has only about £107m of surplus HQLA. If the £1.1bn outflow is not yet in the denominator, HQLA falls to £3.1bn and net outflows rise to £4.659bn; the LCR becomes £3.1bn / £4.659bn = 66.5%. Even if the outflow were already reflected in the denominator, the LCR would be £3.1bn / £3.559bn = 87.1%. Both are well below 115%, so no-action absorption is not credible. The key assumption is that the central bank draw would not itself create a 30-day outflow; that needs confirmation. The most important data gap is whether the £1.1bn is already embedded in the reported LCR and whether it is legal-entity and currency-specific. The board should also confirm the LCR treatment of the Level 2B holdings, because selling them at a 30% haircut raises only about £294m of cash and may not improve the LCR materially. On the stated numbers, Northbridge needs a contingency plan before the downgrade.

The central bank facility is the only option that can reliably deliver cash within ten days. It is secured, so it preserves the franchise better than a fire sale, but it carries interest cost, collateral encumbrance and potential stigma. Covered bond issuance in three weeks is too slow for the immediate outflow, although it could refinance the central bank draw later. Selling Level 2B assets at a 30% haircut crystallises a loss and may not improve the LCR if the assets are already counted with a haircut; it should be a residual option. Raising retail rates by 50bp may slow deposits but is slow, costly and can attract rate-sensitive hot money. The sequence should be: notify the regulator, draw the central bank facility immediately, use retail pricing to stabilise the deposit base, and prepare a covered bond for refinancing. Sizing depends on the denominator. If the outflow is not yet included, restoring 115% requires HQLA of 1.15 × £4.659bn = £5.36bn against £3.1bn, a gap of about £2.26bn. If it is already included, the gap is about £993m. Either figure exceeds the £600m already pre-positioned, so the bank must confirm additional eligible collateral before drawing.

A held-to-maturity sale would convert an unrealised loss into a realised loss, reducing CET1 and possibly triggering a reclassification of the remaining held-to-maturity portfolio. Under IFRS 9, selling more than an insignificant amount can call into question the hold-to-collect business model and force fair-value accounting, which could crystallise further losses. The sale may avoid stigma and secured borrowing costs, and it does not encumber collateral. However, it signals liquidity stress to the market and may weaken the bank's capital position just when confidence is fragile. Central bank borrowing preserves the accounting classification and avoids realising the loss, but it encumbers collateral and may be visible to the market. My recommendation is to use the central bank facility first, provided eligible collateral can be pre-positioned quickly, and to treat held-to-maturity sales as a last resort. If a sale is necessary, the board should disclose the reason, quantify the capital impact and explain why it is not part of a pattern of sales. It should not be used simply to manage earnings or avoid stigma.
