Issuer of Nigerian currency.

**The reasoning** The **Central Bank of Nigeria (CBN)** is the sole authority responsible for issuing Nigerian currency (Naira notes and coins). This is established by the CBN Act of 2007, which gives it the exclusive legal right to print, mint, distribute, and manage Nigeria's money supply. Think of it this way: just as INEC conducts elections, CBN issues currency — it's their constitutional mandate. No other institution, whether commercial bank or government ministry, can legally print Naira. **Why the wrong options tempt you** **First Bank** is Nigeria's oldest bank and handles massive amounts of money, but commercial banks only *distribute* currency, they don't create it. **Ministry of Finance** manages government spending and budgets but doesn't print money — that would mix fiscal policy with monetary policy dangerously. **SEC** (Securities and Exchange Commission) regulates the stock market and investments, not currency. **Quick takeaway** Remember: **CBN = Currency**, just like **INEC = Elections** — each has one exclusive job by law, and currency issuance belongs to the Central Bank alone.
