Tanzania T-bill auction, 21 January 2026: 364-day at 6.23%, up 4 bps
At the Treasury bill auction dated 21 January 2026, the Bank of Tanzania cleared the 91-day bill at 5.76% (up 5 basis points), the 182-day bill at 5.89% (up 6 basis points) and the 364-day bill at 6.23% (up 4 basis points). The rate shown is the weighted average yield of successful bids.
The auction was undersubscribed: bids totalled TZS 184.5bn against TZS 185.0bn on offer, 100% of the amount sought, and TZS 149.2bn was accepted.
Over the past year the 364-day rate has ranged from 5.61% to 12.48%.
A year earlier the 364-day bill cleared at 12.78%, so the government is paying 655 basis points less than twelve months ago.
What this means for TZS 1,000,000
Worked from the published rate · information, not advice
TZS 62,321 in 12 months on the 364-day bill
Put TZS 1,000,000 into the 364-day bill at this auction and you get back TZS 1,062,321 after 12 months: TZS 62,321 in interest before any withholding tax, about TZS 5,193 a month.
That is TZS 417 more than the same money would have earned at the previous auction.
For shorter money: TZS 29,432 on the 182-day bill (6 months), TZS 14,393 on the 91-day bill (3 months).
The government pays the full amount at maturity; the risk is Tanzania’s government not paying, and the money is locked until then.
Kwa Kiswahili
Ukiweka TZS 1,000,000 kwenye hati ya siku 364 kwa riba ya mnada huu, utarudishiwa TZS 1,062,321 baada ya miezi 12: riba ya TZS 62,321 kabla ya kodi yoyote ya zuio, yaani takriban TZS 5,193 kwa mwezi.
Hiyo ni TZS 417 zaidi ya kiasi ambacho pesa hiyo hiyo ingepata kwenye mnada uliopita.
Serikali hulipa yote mwishoni mwa muda; hatari ni serikali kushindwa kulipa, na pesa haipatikani hadi muda uishe.
