Year-over-year growth in Poland’s broad money supply (M3) accelerated in September 2026, signaling a continued expansion in liquidity within the financial system. According to the latest data updated on 22 October 2026, M3 rose by 12.5% compared with September a year earlier.
This marks an increase from August 2026, when the M3 aggregate grew by 11.3% year-over-year. The data indicate that the pace of monetary expansion has strengthened month-on-month on an annual comparison basis, as both the previous (August) and current (September) figures are measured against the same months a year earlier.
The faster growth in M3 suggests that the stock of money circulating in the Polish economy—encompassing cash, deposits, and other liquid assets—continued to build in early autumn, which may have implications for credit dynamics, investment, and future inflation trends. However, the figures only reflect the rate of change and do not provide detail on the underlying drivers of this monetary expansion.
