FX.co ★ UK M4 Money Supply Growth Slows Sharply to 0.3% in December

United Kingdom M4 money supply growth cooled notably in December 2025, with the month-over-month change easing to 0.3%, down from 0.8% in November 2025. The latest data, updated on 30 January 2026, shows a clear deceleration in broad money growth as the year closed.

On a month-over-month basis, the “actual” December figure of 0.3% reflects a weaker expansion in the money stock compared with the previous month’s 0.8% increase, which itself was measured against October’s level. The slowdown suggests a softer pace of liquidity growth in the UK financial system heading into 2026, a development that markets and policymakers will be watching closely for signals on future economic momentum and financial conditions.
