Some brokerage firms also stopped margin lending against insurance companies shares. But Bangladesh Securities Exchange and Commission (BSEC) did not issue any guidelines about margin loan facility on insurance companies.
Mohammad Rezaul Karim, executive director and spokesman for BSEC, said, "The commission has not taken any decision on stopping margin lending on insurance sector shares. However, a house can decide whether to give a margin or not. They may not pay the margin if they think it is risky."
