Tanzania T-bill auction, 25 March 2026: 364-day at 5.20%, down 120 bps
At the Treasury bill auction dated 25 March 2026, the Bank of Tanzania cleared the 91-day bill at 4.16% (down 13 basis points), the 182-day bill at 5.78% (up 18 basis points) and the 364-day bill at 5.20% (down 120 basis points). The rate shown is the weighted average yield of successful bids.
Demand was strong: bids totalled TZS 323.3bn against TZS 185.0bn on offer, 175% of the amount sought, and TZS 185.2bn was accepted.
At 5.20%, the 364-day rate is the lowest in the 20 auctions of the past year.
A year earlier the 364-day bill cleared at 10.75%, so the government is paying 555 basis points less than twelve months ago.
What this means for TZS 1,000,000
Worked from the published rate · information, not advice
TZS 51,958 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 1,051,958 after 12 months: TZS 51,958 in interest before any withholding tax, about TZS 4,330 a month.
That is TZS 12,003 less than the same money would have earned at the previous auction.
For shorter money: TZS 28,891 on the 182-day bill (6 months), TZS 10,402 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 1,051,958 baada ya miezi 12: riba ya TZS 51,958 kabla ya kodi yoyote ya zuio, yaani takriban TZS 4,330 kwa mwezi.
Hiyo ni TZS 12,003 pungufu 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.
