FX.co ★ South Korea’s M3 Money Supply Edges Higher in September, Signalling Gradual Liquidity Build-Up

South Korea’s broad money supply continued its gradual expansion in September 2026, with the M3 aggregate rising to 6,393.8 billion won, up from 6,368.9 billion won in August 2026. The latest data, updated on 13 November 2026, point to a modest increase in liquidity within the Korean financial system.

The uptick in M3 suggests that overall monetary conditions remain supportive, with a steady growth in cash, deposits and other highly liquid assets held by households and businesses. While the increase from August to September is relatively small in absolute terms, it underscores a continuing upward trend rather than any sign of contraction in broad money.

Market participants and policymakers will be watching subsequent releases to assess whether this incremental rise in money supply feeds through into stronger credit growth, asset prices or inflation pressures, or whether it simply reflects a stable, moderately accommodative financial environment.
