The Central Bank of Russia has published a consultation paper setting out tougher credit concentration rules for the banking sector. From 1 January 2028, it plans to revise the N6 and N21 concentration ratios by applying a 100% risk weight to all corporate borrowers, replacing the current approach under which some borrowers receive reduced risk weights. The change will apply to all banks, not only systemically important banks, and the regulator now intends to use the effective concentration ratios rather than introduce a new N30 ratio. The package is designed to reduce the risk that concentrated lending shifts to smaller banks. Institutions with elevated concentration levels will be allowed to reduce them gradually without additional supervisory measures or restrictions. To push banks toward the target of 25% of capital per group of related borrowers, the regulator will require a new contribution to the compulsory deposit insurance fund until that threshold is met. From 2026, banks will also be able to redistribute concentration exposures using credit default swaps and credit digital financial assets, and they will be allowed not to group operationally independent companies as related borrowers. The Central Bank of Russia plans to complete the regulatory framework in 2026 and 2027 so the changes can take effect from 1 January 2028. Feedback on the consultation paper is invited through 5 June 2026, and amendments to the instruction on calculating the ratios will be published soon for regulatory impact assessment.

Central Bank of Russia consults on 100% risk weights for corporate borrowers in concentration ratios for all banks from 2028
The Central Bank of Russia has issued a consultation paper proposing tougher credit concentration rules, including revising the N6 and N21 ratios from 1 January 2028 by applying a 100% risk weight to all corporate borrowers and using effective concentration ratios instead of introducing a new N30 ratio. The measures, which will apply to all banks, aim to prevent concentrated lending from shifting to smaller institutions, allow gradual reduction of elevated concentrations, introduce a new contribution to the compulsory deposit insurance fund for groups of related borrowers above 25% of capital, and permit the use of credit default swaps and credit digital financial assets to redistribute exposures.
