the subsidy that proves the product

Capital invests as capital. If private money enters only because a public or philanthropic tranche absorbs losses forever, the structure has not proved a self-supporting commercial case. It has proved a durable subsidy. A subsidized asset is still an asset.

That is not an argument against blended finance. By the standard definition, blended finance uses catalytic capital from public or philanthropic sources to increase private investment in sustainable development. It can fund preparation, absorb early uncertainty, establish performance history, and bring a new market to the point where ordinary underwriting becomes possible.

The problem begins when the concession never leaves. At that point, first-loss is no longer seasoning the product. It is the product.

blended finance is a diagnostic

The presence of senior capital does not, by itself, prove commercial demand. Senior investors may simply be responding rationally to a loss-absorbing layer placed beneath them. Their participation proves that the subsidy works; it does not prove that the underlying asset clears without it.

That distinction matters in nature finance because UNEP's State of Finance for Nature tracks a persistent need to scale public and private finance for nature-based solutions. Recycling scarce catalytic capital through structures that can graduate expands the market. Locking it permanently under every senior dollar limits scale to the concession provider's balance sheet.

Use blended finance as an underwriting test. It reveals which risks are temporary, which are structural, and whether a real buyer exists for the output.

the three graduation tests

Convergence's definition does not require catalytic capital to exit. The three questions below are this post's commerciality rubric — what we use before calling a structure a self-supporting investment case.

1. Is the concession time-boxed? State a date, term, or finite pool. “Until the market matures” is not a term.
2. Is there a defined graduation event? Name the evidence that releases or retires the concession: completed construction, verified operating history, a signed payment contract, a coverage threshold, a refinancing, or another observable event.
3. Can you name the price at which the senior tranche clears without the concession? Give the coupon, tenor, coverage, and loss assumptions required by an unsubsidized buyer. If that price cannot be named, the product is not yet commercially specified.

A “no” does not make the project unworthy. It changes the honest label. The capital may be a grant, a program-related investment, or permanently concessional funding for a public good. Those are legitimate tools. They are not evidence that commercial capital has accepted the risk on its own merits.

seasoning versus permanent concessionality

Seasoning is common in markets that have real products but incomplete evidence. A first facility may need grants for ecological baselines, legal templates, measurement systems, or transaction costs that later facilities can reuse. Early operating risk may justify a temporary guarantee while performance data accumulates. A junior tranche can bridge construction to contracted operations.

These uses create information, infrastructure, or a track record. Each should reduce the need for the next concessional dollar. If successive comparable transactions still need the same protection as the first, the structure has learned nothing — or the underlying payment stream remains too weak.

policy is the floor, not the coupon

Policy is not useless. It can prohibit damaging conduct, require mitigation or disclosure, standardize claims, authorize procurement, and establish who is responsible for a natural dependency. Those rules reduce uncertainty and can create an obligation or willingness to pay.

But a policy signal is not automatically cash flow. A regulation becomes part of an underwritable coupon only when it produces a funded purchase, contract, tariff, premium, or other enforceable payment. Policy sets the floor under behavior. A product still needs a payor.

This is why capital cannot be asked to invest “for nature” as a substitute for product design. The sibling argument is here: capital doesn't invest for nature. Capital can finance protection when protection is attached to something a buyer is obligated or economically motivated to purchase.

catalytic capital still has a job

We use catalytic capital too. When the goal is a commercial market, the honest role is to pay for uncertainty that can be retired, not to hide a missing customer forever. Foundations can also fund enduring public goods, equity, or market infrastructure without pretending those are graduating assets.

Foundations and public institutions are often the right parties to fund origination, ecological measurement, legal structuring, early loss reserves, or a limited first-loss position. They can take risks that commercial mandates cannot take yet. The discipline is to define what their capital proves and what event allows it to recycle.

That is the difference between catalysis and maintenance. Catalysis changes the conditions of the next transaction. Maintenance holds the same structure upright indefinitely. For the constructive case, see catalytic capital: conservation forever.

If your mandate is to provide a permanent subsidy for an essential public good, opt out of the asset-class claim. Fund it proudly and measure the outcome. If your mandate is to build a commercial product, accept the graduation tests. A senior slice can be market-rate while the whole deal remains concessional. Calling the transaction “market-rate mobilization” when only the senior slice is, protects the pitch, not the market.

manufacturing the missing senior bid

The missing ingredient is not another tranche diagram. It is a credible payment stream for protection.

The ensurance design aims to make protection a property of a specific instrument. Identifiable beneficiaries would pay for continued ecosystem performance; real-asset capital would finance the underlying cost; certificates would connect those payments to a named natural asset or protective purpose; and proceeds would route value from protocol activity and other payors. The protocol is designed to act as a payor where proceeds are available, not only as an arranger waiting for an external buyer.

That is the intended senior bid. A senior investor still needs a named obligor, an enforceable contract, a waterfall, coverage, tenor, currency, and a recovery story. We do not have that pack complete. The full coupon logic belongs in is nature an asset class yet?; it does not need to be rederived here.

Our stage matters. The coupon is still being manufactured. We are building and testing the payor base, proceeds, certificate terms, and evidence needed for senior capital to clear. Catalytic capital can help establish that record. It has not yet earned the right to disappear from every structure, and we will not pretend otherwise.

the graduation path

Start with concession where it resolves a named uncertainty. Define the graduation event before closing. Publish the estimated unsubsidized price range and the assumptions behind it, then test those against third-party bids. Then use each transaction to reduce the concession required by the next one.

Capital invests as capital. Policy is the floor. Nature scales when protection becomes a property of a product with a real coupon. ensurance bakes that requirement into the structure.
