The Bank of Zambia’s new 20-year benchmark bond lengthens the yield curve and gives pension funds a long-dated home for their money. The first auction on 20 November will show what that length costs the Treasury, and the harder question is what the money will be used for.
KEY TAKEAWAYS
- The Bank of Zambia has introduced a 20-year Government bond, the longest tenor yet offered on the domestic market, beyond the 15-year bond.
- The Q4 2026 programme provides for K2.2 billion in Treasury bills and K6.3 billion in Government bonds, with bond auctions on 20 November and 18 December.
- A 20-year benchmark gives pension funds, insurers and other institutional investors a closer match for long-term liabilities, and could ease the refinancing pressure that comes with heavy short-term borrowing.
- Over two decades, investors must price inflation, interest-rate, currency and sovereign risk. The yield cleared at the first auction will set the cost of this borrowing and the tone for secondary-market trading.
- The real test is whether the long-term savings raised finance production, infrastructure, exports and jobs that can generate the revenue needed to repay the debt.
What is Zambia’s 20-year Government bond?
It is a new benchmark Government security that matures 20 years after issue, the longest-dated instrument now available on Zambia’s domestic debt market. The Bank of Zambia announced it on 1 October 2026 as part of the fourth-quarter issuance programme.
The introduction of Zambia’s 20-year Government bond is a significant development for the capital market.
What the Q4 2026 programme contains
The Q4 2026 programme provides for K2.2 billion in Treasury bills and K6.3 billion in Government bonds, with bond auctions scheduled for 20 November and 18 December.
| Instrument | Q4 2026 offer | Auction dates |
|---|---|---|
| Treasury bills | K2.2 billion | Fortnightly: 1, 15 and 29 October; 12 and 26 November; 10 and 24 December |
| Government bonds (including the new 20-year) | K6.3 billion | 20 November and 18 December |

Why a longer yield curve matters
Economically, the 20-year benchmark extends Zambia’s yield curve and creates a longer-term reference for pricing capital.
It also gives pension funds, insurers and other institutional investors more options to match long-term liabilities. A pension fund that owes members retirement income in 2046 can now hold a Government asset that matures around the same time.
It could also reduce the refinancing pressure associated with excessive reliance on short-term borrowing.
What yield will investors demand?
However, the critical question is the yield investors will demand. Over 20 years, investors must price inflation, interest-rate, currency and sovereign risks.
The first auction will therefore be important not only for demand, but also for the cost of Government borrowing and subsequent secondary-market liquidity.
The bigger opportunity: long-term savings for productive investment
The bigger opportunity is to mobilise long-term domestic savings into productive investment.
Ultimately, the question is not simply whether Zambia can borrow for 20 years, but whether that capital can help finance production, infrastructure, exports and jobs capable of generating the revenues required to service the debt sustainably.
