FX.co ★ Saudi Arabia’s M3 Money Supply Growth Eases to 4.8% in September 2026

Saudi Arabia’s M3 money supply growth slowed to 4.80% year-on-year in September 2026, down from 5.60% in August 2026, according to data updated on 29 October 2026. The figures are based on a year-over-year comparison, measuring the change in M3 for each month against the same month a year earlier.

The September reading indicates a moderation in broad liquidity growth in the Saudi economy, following a stronger expansion in August. While M3 continues to grow, the deceleration in the pace of increase may suggest a slightly tighter monetary environment or cooler demand for credit and deposits compared with the previous month. Investors and analysts will be watching upcoming releases to see whether this marks the beginning of a more sustained trend in liquidity conditions.
