FX.co ★ UK M3 Money Supply Edges Higher in August, Reaches £3,306.5 Billion

The United Kingdom’s broad money supply (M3) continued to expand in late summer, with the aggregate rising to £3,306.5 billion in August 2026, up from £3,299.0 billion in July 2026. The latest data, updated on 29 September 2026, indicate a modest monthly increase in the stock of money circulating in the UK economy.

The August reading suggests a continued, if measured, build‑up in liquidity compared with the previous month. While the pace of change remains incremental, movements in M3 are closely watched by market participants and policymakers as a barometer of underlying monetary conditions and potential future trends in spending and inflation.
