Starting January 1, 2026, India will implement significant regulatory and policy changes impacting banking, taxes, and household budgets. Key updates include weekly credit score data updates, mandatory PAN-Aadhaar linking for banking and government services, and enhanced monitoring of digital payments like UPI to curb fraud. Lenders are also expected to adjust interest rates, with some already cutting lending rates. These changes aim to improve financial transparency and security for individuals and families.
