Tenors: 91, 182, 364 days

Understand why the yield curve: longer maturity = higher yield (typically).

In this lesson

Tenors: 91, 182, 364 days 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.

Today’s money mission

Imagine this situation: 91-day T-bill rate: 17%. 182-day: 18.5%. 364-day: 20%. You have 200000 in local currency you will not need for 1 year.

What you need to know

The yield curve: longer maturity = higher yield (typically). Two compensation factors: (1) liquidity premium — money is locked up longer, (2) interest rate risk — if market rates rise, a locked-in lower rate is less valuable. Both justify the longer-tenor premium.

Real-life example

Real-life money moment: 91-day T-bill rate: 17%. 182-day: 18.5%. 364-day: 20%. You have 200000 in local currency you will not need for 1 year. Which maximises your return? The key lesson is: 364-day at 20%: 200,000×20%=40,000.

Progress Penguin connection

Open the investment simulator and compare 91-day, 182-day, and 364-day T-bill yields side by side. Calculate the extra return per day for each longer tenor. Is the additional daily return worth the extra months of lock-up?

Quiz preview

T-bills come in tenors of:

1 day
91, 182, 364 days
10 years
100 years

91-day T-bill rate: 17%. 182-day: 18.5%. 364-day: 20%. You have 200000 in local currency you will not need for 1 year. Which maximises your return?

91-day — most flexible over the longer term as a reliable approach
182-day — best balance when planning ahead in most everyday cases
364-day at 20% — longest term offers highest rate; rolling three 91-day bills at 17% risks lower rates at reinvestment
All tenors produce identical annual returns for the typical person
