FX.co ★ Swiss M3 Money Supply Inches Higher in August, Signalling Steady Liquidity Growth

Switzerland’s broad money supply (M3) continued to expand in late summer, with the aggregate rising to 1,238.2 billion CHF in August 2026 from 1,232.2 billion CHF in July 2026. The latest figures, updated on 21 September 2026, point to a modest month‑on‑month increase in liquidity within the Swiss financial system.

The 6.0 billion CHF uptick in M3 suggests that monetary conditions remained accommodative through August, with a gradual build‑up of deposits and other liquid assets. While the data alone do not signal a directional shift in monetary policy, they will be closely watched by market participants and policymakers as part of the broader assessment of inflation pressures, credit demand, and financial stability in the Swiss economy.

For investors and analysts, the continued growth in M3 serves as a key gauge of underlying monetary dynamics, complementing other indicators such as interest rates, lending volumes, and price developments. The August reading reinforces the picture of a steadily expanding money base as Switzerland moves through the second half of 2026.
