Question

Currently in Zimbabwe there is a cash crisis. The banks are limiting daily withdrawals to $50. People who have cash are taking advantage of the situation and selling cash for a profit. Example: Zaid has considerable cash in the bank, but is unable to withdraw. Since he cannot access his cash, a person with cash sells him for example $1000 for $1,100. Zaid then makes payment of $1,100 by bank transfer. Is this permissible?
