Nigeria T-bill auction, 1 August 2018: 364-day at 11.30%, down 19 bps
At the Treasury bill auction dated 1 August 2018, the Central Bank of Nigeria set stop rates on the 91-day bill at 10.00% (unchanged), the 182-day bill at 10.40% (down 10 basis points) and the 364-day bill at 11.30% (down 19 basis points). The rate shown is the stop (issue) rate at the primary auction.
The auction was fully subscribed: bids totalled NGN 318.2bn against NGN 215.6bn on offer, 148% of the amount sought, and NGN 215.6bn was accepted.
Over the past year the 364-day rate has ranged from 10.70% to 18.52%.
A year earlier the 364-day bill cleared at 18.55%, so the government is paying 725 basis points less than twelve months ago.
What this means for NGN 1,000,000
Worked from the published rate · information, not advice
NGN 113,000 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 1,113,000 after 12 months: NGN 113,000 in interest before any withholding tax, about NGN 9,417 a month.
That is NGN 1,900 less than the same money would have earned at the previous auction.
For shorter money: NGN 52,000 on the 182-day bill (6 months), NGN 25,000 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.
