Tanzania Treasury bills · auction of 14 May 2025

Tanzania T-bill auction, 14 May 2025: 364-day at 9.13%, up 22 bps

At the Treasury bill auction dated 14 May 2025, the Bank of Tanzania cleared the 182-day bill at 8.33% (down 15 basis points) and the 364-day bill at 9.13% (up 22 basis points). The rate shown is the weighted average yield of successful bids.

The auction was undersubscribed: bids totalled TZS 58.0bn against TZS 105.7bn on offer, 55% of the amount sought, and TZS 55.5bn was accepted.

Over the past year the 364-day rate has ranged from 6.75% to 12.99%.

A year earlier the 364-day bill cleared at 8.61%, so the government is paying 52 basis points more than twelve months ago.

What this means for TZS 1,000,000

Worked from the published rate · information, not advice

TZS 91,304 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 1,091,304 after 12 months: TZS 91,304 in interest before any withholding tax, about TZS 7,609 a month.

That is TZS 2,163 more than the same money would have earned at the previous auction.

For shorter money: TZS 41,642 on the 182-day bill (6 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 1,091,304 baada ya miezi 12: riba ya TZS 91,304 kabla ya kodi yoyote ya zuio, yaani takriban TZS 7,609 kwa mwezi.

Hiyo ni TZS 2,163 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.
