CTPD warns Zambia's plan to use domestic borrowing for the 2026 supplementary budget may deepen the debt burden, crowd out private credit, and raise yields.
The Centre for Trade Policy and Development (CTPD) warned that financing part of the 2026 supplementary budget through domestic borrowing could deepen Zambia's debt burden. The warning lands as the government seeks to cover unfunded priorities, forcing a closer look at the costs of tapping local markets.
The CTPD argued that turning to domestic markets for budget financing carries structural risks. Local borrowing drains liquidity from commercial banks and Treasury bill auctions, crowding out private-sector credit. It also pushes up domestic yields as the government competes with private borrowers for funds. Higher yields raise the government's refinancing costs. Over time, the rollover burden increases. The warning specifically tied the supplementary budget's design to a potential reversal of any progress made in stabilising public finances. Zambia's debt-to-GDP ratio remains elevated after external restructuring in 2023. Adding domestic debt without a clear revenue plan could stretch the government's ability to service its obligations.
The risk runs directly into the kwacha and sovereign debt pricing. Domestic borrowing forces the central bank to manage increased liquidity absorption, often through higher policy rates. Higher rates attract short-term capital inflows, which can support the currency in the near term. The trade-off is a drag on economic growth because private investment faces tighter credit conditions. For Zambian sovereign bonds, the warning creates a new layer of uncertainty. Any sign that the government is loosening fiscal discipline tends to raise the risk premium priced into outstanding debt. The supplementary budget was initially presented as a modest adjustment. If domestic borrowing becomes a vehicle for additional indebtedness, investor confidence may erode.
The next concrete marker is the supplementary budget's parliamentary passage. The government must present a repayment plan for the domestic debt it intends to issue. Without a credible schedule, the market will price in higher yields on Treasury bills and long-term bonds. A second marker is the government's choice of financing instruments. Longer-dated bonds push the repayment burden into future years; short-term bills increase immediate rollover risk. The CTPD's warning amplifies pressure on officials to show how they will avoid crowding out private investment while still meeting spending needs.
For now, the warning forces a watchlist decision. The bull case for Zambian assets requires continued fiscal consolidation and external support. The domestic borrowing plan introduces a variable that could break that story. Watch the supplementary budget's final size and the government's detailed financing plan for signals on whether the debt burden will deepen as the CTPD projects.
