CBN's primary role:

**The reasoning** The Central Bank of Nigeria (CBN) is Nigeria's **monetary authority** — it controls the country's money supply and ensures economic stability. Its two core functions are: 1. **Currency issue**: CBN has the exclusive right to print and distribute the Naira. You'll notice "Central Bank of Nigeria" written on every naira note. 2. **Monetary policy**: CBN controls interest rates, manages inflation, and regulates banks to keep the economy stable. Think of actions like adjusting the Monetary Policy Rate (MPR) or setting reserve requirements for commercial banks. This is the principle of **central banking** — one institution controls the nation's money to maintain economic order. **Why the wrong options tempt you** - **A (Tax collection)**: The Federal Inland Revenue Service (FIRS) handles this, not CBN - **C (Police)**: Nigeria Police Force does law enforcement — completely different ministry - **D (Education)**: Federal Ministry of Education manages this These mix up different government agencies. Students confuse them because they're all "government work." **Quick takeaway** Remember: **CBN = Currency + Control of Money** — if the question involves naira notes, interest rates, or banks, think CBN first.
