You Can Now Open A Zenith Bank Account With N0.00

What happened to Zenith Bank and their rigid high minimum account opening balance? Back then, the bank used to charge/demand for a minimum of N50,000 before you allowed to open an account with them. Why are they now willing to come down to 0 naira and even running a Twitter add for such?
I presume this recession has reached their end too. Customers are no longer willing to leave such amount dormant in bank.

You can now open a Zenith Bank Current or Savings Account for ₦0.00 https://t.co/VO7WRrL5cB
