Why Most PPP Bids Fail the Bankability Test — and How to Fix Yours
A surprising number of public-private partnership projects are technically sound, socially valuable, and politically supported — and still never reach financial close. The project dies not in the design room but in the lenders' credit committee. After two decades advising on infrastructure and PPP transactions, we see the same five failure modes again and again. The good news: each is fixable if you address it before you bid, not after.
1. Risk is allocated to the party that can't price it
The first principle of bankability is simple to state and hard to honour: each risk should sit with the party best able to manage and absorb it. Bids fail when the private party is asked to swallow risks it cannot control — demand risk on a road with no traffic history, force-majeure events with no relief, or political/regulatory change with no compensation mechanism. Lenders read those clauses, price in the worst case, and the model collapses. Fix it by mapping every material risk to an owner and a mitigation, and renegotiating the ones parked in the wrong place.
2. Revenue certainty is asserted, not evidenced
"The demand is obviously there" is not a financing case. Whether the revenue is availability-based (government pays for the asset being available) or demand-based (users pay), lenders want a defensible, downside-tested forecast. Availability-payment structures are generally far more bankable in emerging markets precisely because they strip out volume risk. If your structure depends on optimistic traffic, throughput, or uptake curves, expect a haircut — or build in a minimum-revenue guarantee.
Lenders don't finance your base case. They finance your downside case. Model that one first.
3. The currency mismatch nobody wants to name
This is the silent killer of emerging-market infrastructure. Debt and equipment are often hard-currency; revenue is local-currency. A single devaluation can wipe out years of projected return. Bankable structures address FX head-on — through indexation, partial hard-currency revenue, hedging where markets allow, or blended/DFI financing that shares the exposure. A model that ignores FX is not conservative; it is incomplete.
4. The SPV and security package are an afterthought
The special-purpose vehicle, its shareholding, the step-in rights, the escrow and waterfall, the inter-creditor terms — this plumbing is where lenders actually get comfortable. Bids that treat the SPV as a formality discover late that the security package doesn't give lenders enough control in a distress scenario. Design the security architecture early, with lender counsel's likely asks already built in.
5. The offtake / counterparty credit is weaker than assumed
Ultimately someone pays — a utility, a government department, an authority. If that counterparty's credit is weak or its payment history is poor, the whole structure inherits that risk. Strengthening it may require sovereign guarantees, payment-security mechanisms, escrow funding, or DFI/multilateral credit enhancement. Identify the true payer and their real creditworthiness on day one.
The pattern behind all five
Every one of these failures is a risk-and-evidence failure, not an engineering one. The bids that close are the ones where the sponsor has already thought like a lender — allocated risk honestly, evidenced the downside, named the FX exposure, built the security package, and verified the payer. Do that work before submission and you don't just win the bid; you win a project that can actually be built.
