Whose favour is it anyway? Debt-for-nature and the privatised guarantee

Legal & General's commitment of $1bn over five years to a pipeline of debt conversions, led by Enosis Capital, has been received as unambiguous good news: cheaper debt for emerging market sovereigns, longer maturities, and the savings channelled into conservation. Jake Harper's recent interview in these pages presented the case fluently. Cheaper refinancing frees fiscal space; part of the benefit funds outcomes aligned with the UN Sustainable Development Goals; everyone wins.

The framing deserves closer inspection — not because the transactions are bad, but because the account of who is conferring the benefit, and who will bear the cost of a structural change now under way in these deals, is incomplete in ways that matter.

The guarantee did the work

Begin with the mechanics Harper himself describes. A sub-investment-grade sovereign borrows new money on better terms and retires expensive legacy debt. What makes the new money cheap is not the investor's generosity but the credit enhancement: guarantees or insurance from development finance institutions that can lift sub-investment-grade sovereign risk to an investment-grade equivalent. That uplift is what unlocks capital from institutions whose mandates — and, for annuity writers, whose matching adjustment eligibility — confine them to investment-grade assets.

Follow the contributions around the table. The sovereign's interest bill falls because the paper is re-rated. The paper is re-rated because a guarantor stands behind it. The investor supplies capital at a market rate for the wrapped risk — which is what any investor would do, and is the entire commercial premise. In the completed transactions this points to a specific benefactor: the political risk insurance on Ecuador's 2023 Galapagos conversion came from the US International Development Finance Corporation, supplemented by an Inter-American Development Bank guarantee; Belize's 2021 blue bond and Gabon's 2023 conversion likewise relied on DFC cover; Ivory Coast's education swap sat on a World Bank guarantee. The entity conferring the favour, in other words, was the American taxpayer, with multilateral shareholders behind the remainder. Private investors held the enhanced, remote-risk senior claim; the public held the tail.

There is a respectable defence of that arrangement. A contingent liability mobilises private capital at a scale direct aid cannot match, and the DFC's exposure is premium-earning rather than cash out the door. But it should be described as what it is: a fiscal subsidy delivered through a financial structure. The "favour" narrative attributes to the investor what belongs to the guarantor.

The subsidy has been withdrawn

Which makes the structure of the new $1bn programme the genuinely newsworthy development. The market slowed precisely because DFC political risk cover became less readily available, with the current US administration reducing support for the instruments used in Ecuador, Belize, Gabon and El Salvador. The Enosis-led revival replaces the public backstop with private enhancement on two legs: an agreement with AXA XL, signed in January, to insure up to $3bn of debt-for-nature transactions, and Enosis's own Debt-for-Nature Private Credit Enhancement Facility, seeded with a $100m commitment from Zoma Lab, the family office of Ben and Lucy Ana Walton.

Three consequences follow, and none has featured in the celebratory coverage.

First, the enhancement is now more expensive. The DFC priced its insurance with a policy mandate and the US Treasury behind it. A commercial carrier must price for its cost of capital, its reinsurance, and its shareholders' return — on 15-to-20-year political risk exposure to fragile sovereigns. That is not cheap paper, and its cost sits inside the refinancing spread.

Second, the enhancement is less potent. A wrap is worth no more than the wrapper's own credit. Full-faith-and-credit US backing could carry a structure a long way up the rating scale; a commercial insurer's claims-paying rating caps the achievable uplift lower — and rating agencies will also look through to the wrong-way risk, since the global stress scenarios in which emerging market sovereigns default are the same scenarios that test a carrier's capacity. A lower achieved rating means a higher coupon demanded by investors, so the refinancing saving is squeezed from that end too. And a $100m facility standing behind a multi-billion-dollar pipeline can only be partial or first-loss protection; who sits above that thin layer is the question the deal documents will have to answer.

Third, the risk no longer leaves the financial system. In the public-backstop era, sovereign tail risk exited to a government balance sheet. In the new architecture, one insurer wraps sovereign risk so that another insurer can hold it as investment grade. Readers who followed the funded reinsurance debate will recognise the shape: risk circulating between insurance balance sheets under a label upgrade, rather than being removed.

The residual is the conservation

Now the arithmetic. The "conservation dividend" in any of these structures is a residual: the old coupon, minus the new coupon, minus the enhancement premium, minus the structuring, legal and trustee fees. Two of those deductions have just grown. Something must give, and the candidates rank themselves.

The investor's spread will not give — capital at market rates for the wrapped risk is the premise of the programme. The arranger's fees will not give — Enosis exists to earn structuring economics, and its founder spent years building these transactions at Credit Suisse before establishing the firm in late 2024. That leaves the sovereign's relief, and the conservation commitment — the softest claimant in the waterfall, protected by covenants whose breach, as Harper candidly noted, tends to trigger "discussions rather than immediate penalties."

The flagship deal already illustrated how modest the residual can be under the generous regime. Of the roughly $1.1bn in debt-service savings generated by Ecuador's Galapagos conversion, on commonly cited figures some $450m was committed to conservation over about eighteen years — with the remainder absorbed by structure costs and general fiscal relief. Those were the economics with taxpayer-subsidised enhancement. The privately enhanced version of the same transaction delivers less to the turtles, or requires a more distressed sovereign whose legacy coupons are high enough to feed every layer. There is a certain irony in a model that now works best on the most fragile credits, insured by a commercial carrier whose capacity is correlated with their failure.

The question worth asking

None of this is an argument against the transactions. Genuine near-term relief for the sovereign is real; the conservation funding, though a residual, is funding that would not otherwise exist; and the withdrawal of public guarantees was not the industry's choice. It is an argument against the framing. The public version of this market was a subsidy wearing a financial structure. The private version has no subsidy in it: it must be entirely self-financing out of the refinancing spread, which means each deal either captures genuine value — a market that was overcharging the sovereign — or transfers it from someone who has not yet noticed. Distinguishing the two, transaction by transaction, requires the one disclosure the promotional coverage never includes: the full decomposition of the spread, including what the investor earns, what the enhancement costs, and what, after everyone commercial has been paid, is actually left for the stated purpose.

When the guarantee was public, the taxpayer held the tail and the question was whether the subsidy was well spent. Now the guarantee is private, and the question is simpler and sharper: who pays — the sovereign, the insurer's policyholders, or the conservation projects the whole edifice claims to serve?
