Union Minister of State for Finance Jayant Sinha has said that the Reserve Bank of India should conduct asset quality review of banks regularly. Speaking on the sidelines of a function in Mumbai, Mr Sinha said RBI has carried out a detailed investigation into system-wide stressed assets starting June last year and the government has been working very closely with the central bank in this regard. After the review of top 150 stressed companies last December, the RBI reportedly asked banks to classify these accounts as bad loans irrespective of whether they are being serviced or not. This list was later trimmed to 130 companies.
