Quick answerFrom Dec 15, 2025 (with some provisions effective Dec 12, 2025), the CRR/SLR fortnight for rural co-op banks shifts from a Saturday-to-second-Friday cycle to calendar halves (1st-15th and 16th-last day). Reporting forms are revised, and provisional/final/special Form B returns are replaced with a single Form B. Form I is also revised.
The rule, in the simplest words
How it plays out — a real example

As the treasury officer in Indore, I need to ensure that our rural co-op bank's CRR/SLR maintenance and reporting cycles align with the new calendar fortnights. I will update our internal systems and processes to handle the new fortnight definition and revised return formats from mid-December 2025. A treasury officer in Indore must update their internal systems to reflect the new fortnight definition for CRR/SLR maintenance and reporting.

What changed

The Banking Laws (Amendment) Act, 2025 redefines 'fortnight' for CRR and SLR maintenance from the period from Saturday to the second following Friday to the 1st-15th and 16th-last day of each calendar month. Consequently, all references to 'Friday' in the Directions are replaced with 'day' or 'last day of the fortnight' as applicable, and reporting timelines are adjusted: Form B becomes a single fortnightly return (no provisional/final/special), and Form I is revised with new return codes. The new reporting structure takes effect from December 15, 2025 (except paragraph 7(viii)(3) effective Dec 12, 2025), with updated return codes on the CIMS portal. Transitional provisions apply for December 13-15, 2025 and the first two fortnights.

What it means for you

Rural co-operative banks must align their CRR/SLR maintenance and reporting cycles to calendar-based fortnights, which may shift liquidity planning and compliance deadlines. The elimination of provisional and final Form B returns simplifies reporting but requires banks to submit accurate data in a single submission. Banks need to update their internal systems and processes to handle the new fortnight definition and revised return formats from mid-December 2025.
