What T-bills are

Understand why t-bill safety has two components: (1) sovereign backing — the federal government's obligation, considered very low risk, (2) short duration (91-364 days) — limits exposure to interest rate changes.

In this lesson

What T-bills are is part of Treasury Bills Lab. This preview shows how investment-universe connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Imagine this situation: You lend the Nigerian government 500000 in local currency by buying a 91-day T-bill at 18% annual rate.

How it works

T-bill safety has two components: (1) sovereign backing — the federal government's obligation, considered very low risk, (2) short duration (91-364 days) — limits exposure to interest rate changes. Both make T-bills the closest thing to risk-free investment in Nigerian naira.

Apply it to a real decision

Real-life money moment: You lend the Nigerian government 500000 in local currency by buying a 91-day T-bill at 18% annual rate. What do you receive at the end of 91 days? The key lesson is: T-bill interest: 500,000×18%×(91/365)=22,397≈22,500.
