ExampleIf a T-Bill has a face value of ETB 100,000, that is the amount you receive at maturity.
ExampleTo buy ETB 100,000 of a 91-day T-Bill at 12%, the purchase price is about ETB 97,100.
ExampleIn the example above, 100,000 − 97,100 ≈ ETB 2,900 is the discount.
ExampleAt a 12% discount rate on a 91-day bill, ETB 100,000 of face value costs about ETB 97,100 today.
Put simplyA higher discount rate means you pay less today for the same face value.
ExamplePay about ETB 97,100 today and receive ETB 100,000 at maturity → your return is about ETB 2,900 before fees.
ExampleIf one T-Bill offers 12% and another 10%, the 12% offers a higher return.
Put simplyYield lets you compare returns across different T-Bills.
ExampleA 91-day bill bought on 1 Jan matures around 2 Apr, when you receive the face value.
ExampleCommon Ethiopian T-Bill tenors: 28, 91, 182, and 364 days.
ExampleWith a 5,000 denomination, 4 bills = ETB 20,000 of face value.

ExampleA 0.1% fee on a ~ETB 97,100 purchase is about ETB 97.
ExampleInvest-today about ETB 97,100 + ETB 97 fee ≈ ETB 97,197 total outlay.
ExampleReceive ETB 100,000 at maturity − ETB 97,197 net investment ≈ ETB 2,803 net return.

ExampleA bid rate of 13% means you won't accept a return below 13%.
ExampleYou bid ETB 100,000 and the full ETB 100,000 is awarded: a 100% allocation.

ExampleA maximum accepted price of ETB 97.20 per 100 is the lowest-yield bid that was accepted.
ExampleA minimum accepted yield of 12.1% pairs with the maximum accepted price.
ExampleA maximum accepted yield of 13.5% equals the cut-off rate.
ExampleA weighted average price of ETB 96.80 means investors paid an average of 96.80 today to receive 100 at maturity.
