UK confirms £400m backing of TFFF ahead of bond market entry

The UK government confirmed its backing for TFFF last week, bringing total sovereign investment to $7.3bn and extending its support for what could become a major emerging market debt vehicle funding the protection of tropical rainforests.

Launched at COP30 last year, TFFF aims to raise some $125bn, of which $25bn will come from public and philanthropic sources and $100bn from private investors.

The UK’s latest backing comes on the back of earlier investments from Brazil, Indonesia, France, Germany, Norway, and two philanthropic backers. It constitutes a loan rather than a grant, offering the UK a seat at the table in the fund’s governing body.

The facility’s success leans entirely on investment returns; forest countries will not be expected to repay this funding. Instead, the facility is designed to generate investment returns from its performance-based model, enabling it to both repay investors and reward countries that successfully protect tropical forests.

A key litmus test for the fund is now the planned launch of the Tropical Forest Investment Fund, which will be established in October with a view to drawing in private investors.

The new fund will be domiciled in Luxembourg as a Reserved Alternative Investment Fund (RAIF), allowing it to operate as a flexible blended finance vehicle under European regulations.

Once launched, the fund is set to invest in a portfolio of liquid, publicly listed bonds covering the range of developed and emerging markets, including a combination of sovereign and corporate issuers. A key factor to consider will be the percentage of the portfolio to be invested in emerging and frontier markets. 

Earlier analysis by the Anthrophocene Fixed Income Institute suggests that this could reduce spreads by more than 2 basis points resulting in cost savings of some $7.5bn. 

Time to step up

But with less than a third of targeted sovereign investment reached to date, Edward Davey, head of WRI Europe's UK Office, argues that more support is needed if the project is to become a success.

"Now is the moment for other governments to step up — building on this renewed momentum from the UK and earlier pledges from other nations," he said. "With more investment and smart governance, this mechanism could provide countries with the long-term incentives they need to keep forests standing, while ensuring Indigenous Peoples and communities have the finance, tenure, and rights to the land they have protected for generations."

Nature as investable asset class

Richard Kelly, managing director at Foresight Group, said that the announcement stood out not for the size of the transaction but its structure.

"The government has been explicit that this is being made as an investment rather than a grant, reflecting a broader shift in UK natural capital policy. Increasingly, nature is being viewed as an investable asset class capable of delivering both environmental outcomes and financial returns at scale."

"We are seeing similar thinking in the Woodland Carbon Purchase Fund, where government is seeking both to stimulate market demand and generate a return for taxpayers. The advantage of this approach is that public capital can potentially be recycled and attract additional private investment, creating a more durable source of funding than traditional grant or aid-based programmes."

Potential private investors

Next month’s planned launch is taking place against a challenging market backdrop, with sovereign borrowing costs having shot up due to the Iran conflict. But growing challenges for developed market bond issuers could benefit emerging markets, as some of the world’s largest managers, including BlackRock and JP Morgan, have recently pivoted towards increased allocations to emerging markets.

During this year’s London Climate Action Week, 12 major institutional investors expressed initial support for the initiative, with Pimco, one of the world’s largest fixed income investors, coming out as the leading signatory.

Robeco, Schroders, Impax Asset Management, RBC, Barclays, and Bank of America have also expressed their interest, though precise volumes of backing are still to be determined. Ultimately, their returns depend on the yield spread between the low-rate sponsor loans and the higher-yielding emerging market sovereign bonds the fund will buy.
