RBI's final co-lending rules expand scope, mandate 10% loan retention, and enforce stricter risk-sharing from January 2026.

• Co-lending is now allowed beyond priority sector lending, with stricter norms on exposure, disclosures, and loan classification.
• Lenders must retain 10% of each loan and report their share within 15 days of disbursement.
• Default loss guarantees are capped at 5%, and borrower-level defaults impact both partner lenders’ exposures.
