Lending to Cities: Sub-Sovereign Finance in African Markets

African urbanisation is fastest at municipal level, where the infrastructure need sits. The financing capacity of those municipalities is the constraint, and it is being addressed slowly.

01

Where the need is

Water, sanitation, transport, and housing are delivered locally. Cities across the continent are growing faster than national populations, and the infrastructure gap is concentrated at that level.

Municipal financing capacity has not kept pace, for reasons that are structural.

02

What limits borrowing

Revenue base. Many municipalities depend on transfers from central government rather than on own-source revenue. A borrower whose income is an annual transfer decision has limited capacity to commit to long-term debt.

Legal authority. Whether a municipality may borrow, from whom, in what currency, and with what approvals varies considerably. In several jurisdictions borrowing requires central government approval, which brings sovereign debt considerations into a local decision.

Creditworthiness assessment. Few municipalities are rated, and financial reporting is often delayed or incomplete. Lenders cannot assess what is not reported.

Ring-fencing. Where a revenue stream exists — water tariffs, property rates, parking — whether it can be legally dedicated to debt service rather than flowing into a general fund determines whether a structure is possible.

03

Structures that work

Revenue-backed project structures. Rather than lending to the municipality, financing a specific asset with a dedicated revenue stream, ring-fenced in a structure the lender can rely on.

Municipal development funds. A national intermediary borrows at sovereign or near-sovereign cost and on-lends to municipalities with technical support attached. Several markets operate these, and they address both the cost and the capacity problem.

Pooled financing. Aggregating several municipalities' borrowing into one instrument, which spreads risk and reaches a size that institutional investors can consider.

Guarantees. Partial credit guarantees lifting a municipal instrument into a rating domestic institutional investors can hold.

04

What has to be built first

  • Financial reporting current enough to be assessed
  • Legal clarity on borrowing authority and the approval path
  • Revenue that can be identified and dedicated
  • Project preparation capacity, which is frequently the binding constraint
  • A realistic view of tariff levels and collection, not a policy aspiration

The municipalities that borrow successfully are usually those that spent several years on the first two points before approaching the market. That is unglamorous work and it is the actual precondition.
