Tanzania T-bill auction, 19 November 2025: 364-day at 6.35%, down 20 bps
At the Treasury bill auction dated 19 November 2025, the Bank of Tanzania cleared the 91-day bill at 5.69% (down 78 basis points), the 182-day bill at 5.87% (down 10 basis points) and the 364-day bill at 6.35% (down 20 basis points). The rate shown is the weighted average yield of successful bids.
Demand was strong: bids totalled TZS 440.0bn against TZS 155.0bn on offer, 284% of the amount sought, and TZS 155.0bn was accepted.
Over the past year the 364-day rate has ranged from 5.61% to 12.99%.
A year earlier the 364-day bill cleared at 12.78%, so the government is paying 643 basis points less than twelve months ago.
What this means for TZS 1,000,000
Worked from the published rate · information, not advice
TZS 63,489 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 1,063,489 after 12 months: TZS 63,489 in interest before any withholding tax, about TZS 5,291 a month.
That is TZS 2,029 less than the same money would have earned at the previous auction.
For shorter money: TZS 29,336 on the 182-day bill (6 months), TZS 14,237 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 1,063,489 baada ya miezi 12: riba ya TZS 63,489 kabla ya kodi yoyote ya zuio, yaani takriban TZS 5,291 kwa mwezi.
Hiyo ni TZS 2,029 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.
