Nigeria T-bill auction, 29 March 2023: 364-day at 14.74%, up 525 bps
At the Treasury bill auction dated 29 March 2023, the Central Bank of Nigeria set stop rates on the 91-day bill at 6.00% (up 345 basis points), the 182-day bill at 8.00% (up 300 basis points) and the 364-day bill at 14.74% (up 525 basis points). The rate shown is the stop (issue) rate at the primary auction.
The auction was fully subscribed: bids totalled NGN 168.6bn against NGN 145.5bn on offer, 116% of the amount sought, and NGN 145.5bn was accepted.
Over the past year the 364-day rate has ranged from 2.24% to 14.84%.
A year earlier the 364-day bill cleared at 4.00%, so the government is paying 1074 basis points more than twelve months ago.
What this means for NGN 1,000,000
Worked from the published rate · information, not advice
NGN 147,400 in 12 months on the 364-day bill
Put NGN 1,000,000 into the 364-day bill at this auction and you get back NGN 1,147,400 after 12 months: NGN 147,400 in interest before any withholding tax, about NGN 12,283 a month.
That is NGN 52,500 more than the same money would have earned at the previous auction.
For shorter money: NGN 40,000 on the 182-day bill (6 months), NGN 15,000 on the 91-day bill (3 months).
The government pays the full amount at maturity; the risk is Nigeria’s government not paying, and the money is locked until then.
