When to buy Political Risk Insurance, how to size it, and how multilateral guarantees crowd in commercial debt on African infrastructure transactions.

Political risk is not the same as political instability. A stable democracy can still expropriate. A post-conflict state can still honour every contract. What matters to lenders is whether the risk is transferable — and Political Risk Insurance (PRI) is the instrument that transfers it.
What PRI actually covers
Most PRI policies cover four perils. Each has a specific legal definition — the wording matters.
Expropriation — outright nationalisation, creeping expropriation, confiscation of project assets or the SPV.
Currency inconvertibility & non-transfer — inability to convert local-currency revenues into hard currency, or to transfer them out of the country.
Political violence — war, civil disturbance, sabotage, terrorism affecting project assets or operations.
Breach of contract / arbitral award default — host-government or state-owned off-taker failing to honour a contract, including failure to pay an arbitral award.
Who provides it
Four categories of provider dominate African infrastructure PRI:
MIGA (Multilateral Investment Guarantee Agency — World Bank Group) — the largest. Up to USD 250m per project, 15-year tenor, cover of all four perils.
African Trade & Investment Development Insurance (ATIDI, formerly ATI) — Africa-specific. Smaller tickets (typically USD 50m–USD 150m) but faster and regional-familiar.
ECAs with PRI capacity — UK Export Finance, US DFC, Euler Hermes, SACE, Nexi. Usually tied to home-country equipment or services.
Lloyd's syndicates / private PRI market — highly flexible wordings, often for top-up cover above multilateral tranches.
Partial Risk Guarantees — the other tool
PRI insures. A Partial Risk Guarantee (PRG)guarantees. The practical difference: if a host government fails to honour a specific obligation (tariff adjustment, convertibility, land access), the PRG provider pays lenders directly, and then subrogates against the government.
The key providers are:
World Bank PRG / Guarantees — via IBRD and IDA.
AfDB PRG — under the Partial Risk Guarantee framework.
If your main concern is host-government contractual default on a sovereign or sub-sovereign obligation — look at World Bank / AfDB PRG first.
If the main risk is currency transfer or inconvertibility — MIGA is typically the cleanest solution.
If you need expropriation and political violence — MIGA is the default; ATIDI is a strong regional alternative.
If you need capacity above the multilateral single-project limit — the private Lloyd's market tops up.
If the project has export credit content — start with the relevant home-country ECA.
How PRI crowds in commercial debt
Commercial banks apply internal country limits to each market. A PRI or PRG wrap converts the risk from country risk to multilateral counterparty risk (often AAA-rated). That does two things:
Frees up bank country limits, allowing larger commercial tranches.
Lowers the capital weighting under Basel, reducing the bank's cost of capital and therefore the pricing passed to the project.
On a well-structured African transaction, a MIGA wrap can compress commercial debt pricing by 150–300 basis points versus uncovered pricing.
Sizing the cover
PRI is priced as an annual premium on the outstanding insured exposure (typically 0.5%–1.5% p.a. depending on risk, tenor and perils). It is not free, and oversized cover destroys returns. The sizing principle:
Cover only the commercial debt tranche (DFIs and ECAs already carry their own risk tolerances).
Cover decreasing exposure — PRI pari-passu with the debt amortisation profile.
Consider partial-percentage cover (e.g. 90% of loss) rather than 100% — cheaper and still de-risks sufficiently.
The documentation
A PRI arrangement involves three core documents:
The Contract of Guarantee or Policy of Insurance between the provider and the insured (usually the lender).
A Subrogation Agreement — once paid, the provider steps into the lender's rights against the defaulting party.
A Host Country Agreement (for MIGA-covered deals) — the host government acknowledges and commits to cooperation with MIGA.
What we do on engagements
On every engagement where political risk is material, we build a risk-instrument matrix — every political risk mapped to the specific instrument (MIGA, ATIDI, PRG, ECA cover, private market), the indicative premium, and the effect on the capital stack. This lets the sponsor decide which risks to transfer and which to retain, before going to credit committee.
