The Reserve Bank of India (RBI) has tightened customer due diligence (CDD) norms by requiring banks and regulated entities to adopt a risk-based approach for periodic updating of Know Your Customer (KYC) information. The amendments to the Master Direction on KYC follow government instructions related to money laundering rules, unlawful activities, and the prevention of weapons of mass destruction. The RBI has also updated instructions in line with recommendations from the Financial Action Task Force. The amended provisions will come into effect immediately.
