What is money laundering in banking?

Written by Editorial Team | Last Updated: August 2026

Money laundering in banking is an illicit financial process through which criminal organizations or individuals seek to disguise the illegal origins of accumulated wealth, making dirty money appear legitimate. This deceptive practice typically involves a three-step cycle consisting of placement, where illegal cash is introduced into the financial system; layering, involving complex transactions to distance funds from their source; and integration, where funds are reinvested into legitimate commercial assets or luxury items. Banks deploy strict anti-money laundering compliance controls to detect and block these illegal maneuvers.
