How to read an NBE auction result

Each NBE results table has one column per term and the same rows every time.

Amount offered
How much NBE set out to sell in that term, in millions of birr.
Bids received
The total amount bidders asked for. More bids than the amount offered means demand exceeded supply.
Total amount accepted
How much was actually sold. It can be less than the amount offered when bids are short or priced too low.
Cut-off price and yield
The lowest price NBE accepted, per 100 birr of face value, and the yield it implies: the highest yield any accepted bidder receives.
Weighted-average price and yield
The average of all accepted bids, weighted by amount. This is the figure this site charts.

From price to yield

NBE's published yields match a simple annual rate on a 365-day year: (100 ÷ price − 1) × 365 ÷ days, to within rounding.

For example, in auction 1012/2026 the 364-day bill's weighted-average price was 92.958 per 100: (100 ÷ 92.958 − 1) × 365 ÷ 364 = 7.596%, against a published yield of 7.597%.
