Exploiting the recalibration of ECB's outstanding central bank funding in 2022, we show that a sharp reabsorption of bank liquidity induces a tightening impact on credit supply, as intended when central banks reduce their balance sheets.

Moreover, we show that the associated reduction in credit supply has real economic effects.
