The United Kingdom’s M4 money supply moved back into positive territory in August 2026, rising 0.4% month-over-month after a 0.3% decline in July, according to data updated on 29 September 2026. The shift marks a modest rebound in broad money growth, which tracks cash in circulation plus bank deposits and is often monitored as an indicator of underlying financial conditions.
The latest figure contrasts with July 2026, when M4 fell 0.3% compared with June, pointing at that time to a slight contraction in liquidity. The August increase therefore represents a turnaround in the month-on-month trend, suggesting that overall monetary conditions in the UK became somewhat more expansionary as the summer progressed.
Under the comparison framework, the “actual” August reading reflects the change versus July, while the “previous” figure captures July’s change versus June. This month-over-month lens highlights the short-term shift from negative to positive money supply growth between July and August 2026.
