Elections has made an insignificant contribution towards family bank loss.
The real cause is the near bank run that happened in October 2016. Depositors withdrew nearly 20Billion in just 5 days. In fact their liquidity ratio went below the minimum 20% central bank requirement. Reduction in deposits= Slowdown of lending. Compared to 2016, the bank has seen a reduction of its loan book by 12 billion which has resulted in interest income dipping by 50%.
Another element is the interest rate cap. They were getting deposits at almost 0% and lending at 18%. Now they get deposits at 7% and lend at 14%. The margin has been reduced by more than half.
