At Hament Advisory we work with families on plans that hold up whether markets are calm or noisy. Right now, something quiet is happening in Tanzania's bond market that will affect a lot of ordinary savers — even those who never think about bonds at all.

When the yield on a government bond falls, is that good news or bad news for the family that quietly parked its savings in a bond fund? The honest answer is: both — and the difference between the two is where most retail unit-holders get confused.

The government's 25-Year Treasury Bond used to pay about 15.7% two years ago. At the latest auction in February 2026, that dropped to 11.99% — the lowest ever recorded. If you hold units in UTT AMIS Bond Fund or Wekeza Maisha, this affects you directly. Here's why.

Think of a Bond Like a See-Saw

A bond is a loan you give the government. In return, the government promises to pay you a fixed interest every six months, and give your money back after a set number of years.

Now imagine a see-saw. On one side sits the interest rate. On the other side sits the price of the bond. When interest rates go down, the price of bonds already out in the market goes up — because a bond that pays a high fixed interest is more valuable when new bonds are only paying low interest. And the reverse is also true.

That's the whole trick. When rates fall, existing bonds become worth more, but new bonds pay less.

What's Happening Right Now

At the last big auction, investors were so eager that they offered seven times what the government was selling — a record. Total bids came in at TZS 1.31 trillion, more than double the usual amount. Everyone wants in, so the government can afford to pay less. That's why rates have dropped.

The bonds themselves are now trading at TZS 109.87 for every TZS 100 of face value — meaning buyers are paying 10% above face value just to secure them. This is what a hot bond market looks like.

What This Means for UTT AMIS Bond Fund

UTT AMIS Bond Fund holds a big pile of these government bonds, many bought years ago when rates were higher. Because those older bonds now trade at higher prices, the fund's unit value has been climbing steadily — from TZS 117.21 in June 2024 to TZS 120.94 in June 2025 and TZS 121.36 by December 2025.

Open your app and the number looks bigger. Nice. But here's the catch.

Every shilling of new money going into the fund today is being used to buy bonds at 11.99% — not the 14% or 15% that older members enjoyed. And every six months, when the older bonds pay their interest, that cash also has to be reinvested at today's lower rates. Slowly, quietly, the income the fund can generate going forward is shrinking.

The fund's unit value is rising, but its future ability to pay you is falling. Both things are happening at once.

Wekeza Maisha Works the Same Way

Wekeza Maisha is a mix of investment and insurance, with a ten-year lock-in. About 69% of its money is in government bonds. The same cascade applies: its unit value rose from TZS 904.47 to TZS 1,047.43 over the past year as bond prices climbed — but the interest it will earn on future money is now lower.

If you're locked in for ten years, you're not just riding today's numbers. You're riding whatever rates do over the whole decade.

The Illusion — and Why Inflation Makes It Worse

This is the trap. A rising unit value feels like a win. But part of that win is one-off — it's tomorrow's return brought forward into today. As the bonds get closer to maturity, that boost fades.

And then there's inflation. Official inflation was 3.2% in February 2026, which sounds fine against a 12% return. But food prices rose 5.7% in the same period — and food is a much bigger share of most Tanzanian family budgets than the official basket suggests. Your real cushion is smaller than the headline number.

What If Rates Go Back Up?

The cascade also runs backwards. If rates rise — because of policy changes, external shocks, or fiscal pressure — the price of bonds already in the fund falls. That means your unit value can drop, wiping out the paper gains of the past two years. Longer bonds swing more sharply than shorter ones, and the 25-year bond swings a lot.

For now the Bank of Tanzania is holding rates steady. But when rates sit at record lows, there's more room to rise than to fall.

What Families Can Think About

You don't need to become a bond expert to be sensible about this. A few things worth considering with an adviser:

  • Don't lock everything into long bonds. Mix in shorter-term or liquid options so not all your money moves in the same direction at the same time.
  • Look at real returns, not headline ones. After inflation, especially food inflation, what is the fund actually giving you?
  • Diversify beyond Tanzania. International bonds via a platform give you exposure to different interest-rate cycles.
  • Understand what you're seeing on your statement. Part of a rising number is a genuine gain. Part is future income brought forward.

A Closing Question

If your bond fund's NAV is rising while its future income is quietly shrinking, do you actually know which part of your return is a durable yield and which part is simply tomorrow's return borrowed into today?

That is not a question to answer alone. If you hold UTT AMIS Bond Fund, Wekeza Maisha, or any other bond-heavy investment and want to understand what's actually happening under the bonnet — and how to build something more inflation-resilient for your family — talk to Hament Advisory.
