The Reserve Bank of India has amended its 2025 investment portfolio directions for rural co operative banks, changing the Investment Fluctuation Reserve requirement in response to operational constraints in maintaining the reserve. Rural co operative banks must now maintain an Investment Fluctuation Reserve of at least 5 per cent of the investment portfolio classified under the Current Category. The minimum requirement will be assessed annually and calculated with reference to the book value of Current Category investments as of the balance sheet date. The amendment replaces paragraph 115(1) of the 2025 directions on the classification, valuation and operation of investment portfolios and takes effect from the date of issue.
