Banks will have to calculate the incremental provisioning every quarter and during times of stress every month and the adequacy of banks' risk management will be monitored from time to time. The central bank has asked banks to gather details of unhedged forex exposure of every corporate borrower and estimate the impact of the movement of the exchange rate on such exposures.
