Sénégal : Pourquoi les investisseurs se bousculent malgré l’envolée des taux d’intérêt
Senegal has once again turned to the regional financial market to finance its budgetary needs, in a context where WAEMU member states are increasing debt issuance to cover growing deficits and refinance maturing debts. On April 30, 2026, the Senegalese Treasury raised 26.06 billion CFA francs through a simultaneous issuance of 357-day Treasury Bills (BATs) and three-year Treasury Bonds (OATs), organized with UMOA-Titres.
The operation generated more interest than the target amount. While the government initially aimed for 30 billion CFA francs, investors submitted bids totaling 34.56 billion CFA francs, representing an oversubscription rate of 115.20%. This level reflects continued strong demand for Senegalese securities on the regional market, even in an environment where the financing needs of West African states remain particularly high.
The final amount allocated, lower than the initial target, nevertheless demonstrates that the question of financing costs remains central. Weighted average yields stood at 7.29% for 357-day bills and 8.05% for three-year bonds, levels that remain high for a government seeking to sustainably finance its public spending.
These rates reflect two realities. On the one hand, investors still consider Senegal's credit rating attractive enough to respond massively to bond issuances. On the other hand, they are now demanding higher returns to lend to countries in the zone, in a context marked by a general rise in interest rates, increasing budget deficits, and strains on the public finances of several WAEMU countries.
Since 2022, the cost of regional debt has gradually increased. The tightening of monetary policies in several major global economies, combined with inflationary pressures and the rise in key interest rates by the BCEAO, has contributed to making financing conditions more expensive in the regional market.
For governments, this trend complicates budgetary decisions. Borrowing remains essential to finance infrastructure, social spending, and public investment, but each interest rate hike mechanically increases the future debt burden. The higher the yields, the larger a share of public revenue is tied up in repaying interest and principal.
The very structure of this issuance illustrates Senegal's current strategy. By combining short and long maturities, the Treasury seeks to smooth its refinancing risk over time. The 357-day bills allow for the rapid mobilization of liquidity, while the three-year bonds slightly extend the average duration of the debt.
The maturities considered nevertheless show that regional markets remain dominated by short-term financing. In several WAEMU countries, states are still struggling to borrow heavily over very long maturities at sustainable costs, which forces them to regularly return to the market to refinance their commitments.
The 6.30% annual coupon on three-year bonds reflects this more expensive financial environment. Just a few years ago, some countries in the region were borrowing at significantly lower rates. Today, investors are more selective and pay closer attention to fiscal trajectories, debt levels, and macroeconomic outlooks.
In the case of Senegal, financing needs remain significant as the country continues its public investments and gradually enters its oil and gas production phase. The authorities are therefore striving to maintain regular access to the regional market while diversifying the instruments used.
This operation ultimately demonstrates that Senegal retains a real capacity to mobilize on the WAEMU market, but it also confirms that this liquidity now comes at a significantly higher price than before.
