Several regulatory and financial changes came into effect on January 1, 2026. Linking PAN with Aadhaar became mandatory for accessing most banking and government services; accounts that remained unlinked faced disruptions. Credit bureaus now update customer repayment data on a weekly basis instead of every 15 days. Account holders can now add up to 4 nominees in a single bank account. SBI, PNB, and HDFC Bank introduced new fixed deposit interest rate slabs.

On the telecom front, SIM verification norms became stricter, particularly for messaging apps like WhatsApp and Telegram. UPI fraud prevention measures were also tightened. For farmers, a unique farmer ID became mandatory in several states to receive PM-Kisan payments, and crop insurance rules expanded to cover damage caused by wild animals if losses are reported within 72 hours.
