Why Burundi’s investors are saying yes to long-term bonds and no to short-term debt

Burundi’s latest government debt auction tells an interesting story about where investors believe they can get the best value for their money.

Banks and other large financial institutions were happy to buy the government’s two-year bonds. But when it came to short-term Treasury bills, they showed far less interest. The difference is striking and offers a glimpse into how Burundi’s financial market is slowly becoming more selective, even if it is still relatively small.

To understand what happened, it helps to know how the government borrows money.

Like many countries, Burundi does not rely only on taxes to pay for public spending. It also borrows from investors. Instead of going to a commercial bank for a loan, the government issues securities that investors can buy. In return, it promises to repay the money later with interest.

There are two main types. Treasury bills are short-term loans that last from a few months to one year. Treasury bonds are longer-term loans, usually lasting several years. Because investors have to wait longer to get their money back, bonds generally pay a higher return.

Last week, the government hoped to borrow FBu37bn by selling Treasury bills. It did not come close.

Investors submitted offers worth only FBu8.45bn, and the government eventually accepted FBu7.45bn. That means the Treasury raised only about one-fifth of the amount it originally wanted.

That does not necessarily mean investors have lost confidence in the government. A more likely explanation is that they simply found better opportunities elsewhere, including in the government’s own bond market.

The bond auction produced almost the opposite result.

The Treasury was looking to borrow FBu8bn through a two-year bond. Instead, investors offered FBu21.7bn, almost three times the amount the government had asked for. Rather than sticking to its original target, the Treasury decided to take advantage of the strong demand and borrowed FBu12.2bn.

So why were investors willing to lend money for two years but not for just a few months?

The answer largely comes down to returns.

The shortest Treasury bills currently offer an annual interest rate of around 9.5 per cent. One-year bills pay about 11.5 per cent. The two-year bond, however, delivers an effective return of just over 14 per cent. For an institution managing billions of francs, that difference matters. If the government is offering a noticeably higher return for a longer commitment, many investors are prepared to wait.

It is also worth remembering who these investors are.

This is not a market where ordinary savers typically participate. Buying government securities requires a minimum investment of BIF50m for Treasury bills and BIF100m for Treasury bonds. 

That is well beyond the reach of most households. Instead, the market is dominated by commercial banks, insurance companies, pension funds and other institutional investors that manage large pools of money.

These institutions tend to think differently from individual investors. They are not looking for quick gains. Their job is to place money where it will generate stable returns while keeping risk under control. Sometimes that means accepting a lower return in exchange for flexibility. Other times, as last week’s results suggest, they are willing to lock up their money for longer if the reward is attractive enough.

The report also sheds light on another part of Burundi’s financial market that receives much less attention: the secondary market.

After investors buy government securities directly from the Treasury, they can later sell them to someone else before they mature. Think of it like buying a house. You do not have to live in it forever, you can sell it if you need the money. Government bonds work in much the same way.

A busy secondary market is generally seen as a good sign because it gives investors confidence that they can sell their holdings whenever they need cash. It also helps determine the true market value of government debt.

In Burundi, however, that market remains quiet.

During the week, only one trade took place. Securities worth FBu398m changed hands even though more than FBu4.2bn were available for sale. In other words, most of the bonds on offer did not find buyers. Orbit Investment Bank described demand in the secondary market as weak, a reminder that Burundi’s capital market is still developing and remains relatively illiquid.

None of this is unusual for a young financial market. Building a deep and active bond market takes time. Investors need confidence that they can buy and sell easily, while governments need to issue debt regularly enough to create a steady flow of securities.

Even so, the latest auctions offer an encouraging sign.

The government had little trouble attracting money for its longer-term bonds, suggesting investors are still willing to finance public borrowing when the price is right. At the same time, the weak demand for short-term Treasury bills is a reminder that investors are paying closer attention to value than before.

That may not sound dramatic, but it is an important shift. Rather than buying almost everything the government puts on the market, investors appear to be making more deliberate choices. For Burundi’s financial market, that could be a sign of gradual maturity rather than weakness.
