How Nigerian Treasury Bills Work

📋 Flexible Tenor

T-Bills are issued for 91, 182, and 364 days at primary auction. On the secondary market you can buy and sell any remaining tenor — from 1 day to 364 days.

💶 The Discount Mechanism

You buy at a discount to face value. If a ₦1M T-Bill costs ₦838,000 today, your ₦162,000 discount is your return at maturity.

📈 Secondary Market

You can buy and sell T-Bills before maturity through licensed dealers and stockbrokers. The price and effective yield adjust based on days remaining.

✅ WHT Exempt

Treasury Bill returns are exempt from Withholding Tax in Nigeria — unlike Fixed Deposits which attract 10% WHT on interest earned.
