The Reserve Bank of India is not considering revisiting its recently announced norms on bank financing for traders and brokers, Governor Sanjay Malhotra said on Monday. He also ruled out any systemic risk arising from the IDFC First Bank fraud. The RBI recently mandated that banks must secure 100% collateral when funding brokers and capped total exposure to 40% of their tier-1 capital. It has also barred bank funding for proprietary trading by brokers.
