The study comes as the Autonomous Sinking Fund (CAA) estimates the country's PPP investment pipeline at CFA4.895 trillion as of the end of March 2026, equivalent to 14.1% of GDP. Instead, it reflects the total investment value of PPP projects whose financing structures, guarantees and contractual commitments require ongoing monitoring. While the central bank does not directly finance infrastructure projects, its prudential rules influence commercial banks' ability to commit funds over long periods. That figure represents the estimated value of a cross-border infrastructure project rather than a direct budgetary obligation for Cameroon. The study awarded to Polygone SARL does not introduce new PPP financing reforms.
