How Export Credit Guarantees Shape Global Energy Infrastructure

In February 2024, the German government approved a financial guarantee for the sale of a deep drilling rig built by the manufacturer Herrenknecht. The buyer was Eneva, a Brazilian energy company operating in the Parnaíba Basin. By July 2025, the rig had arrived in South America, and within six months, it had drilled seven new gas wells. The transaction was made possible not by a traditional commercial loan alone, but by a state-backed instrument known as an export credit guarantee.[4]

When civil society groups highlighted the deal in August 2026, it threw a spotlight on one of the most powerful, yet least understood, mechanisms in global finance. Export credit agencies (ECAs) are the invisible scaffolding of international trade. They underwrite roughly $430 billion of business activity abroad annually, dwarfing the direct project finance provided by multilateral institutions like the World Bank.[3][4][5]

To understand how the global energy system is built, one must understand how it is financed. Heavy infrastructure—whether a gas drilling rig, a solar farm, or a wind turbine factory—requires massive upfront capital. When an exporter wants to sell this equipment to a buyer in an emerging market, commercial banks often balk. The perceived risk of political instability or commercial default is simply too high to offer a viable interest rate.[1]

This is where the export credit agency steps in. An ECA is a private or quasi-governmental institution that acts as an intermediary on behalf of a national government. If the transaction aligns with the state's strategic and economic interests, the ECA will issue a guarantee. It essentially promises the commercial lender that if the foreign buyer defaults, the exporting country's government will absorb the loss.[2]

Because this guarantee is backed by the sovereign credit rating of a developed nation—such as Germany's AAA rating—the risk profile of the entire transaction plummets. The commercial bank can then offer the foreign buyer a loan at a significantly lower interest rate, making the massive capital purchase economically viable.[1]

Different countries structure these agencies differently. The Export-Import Bank of the United States (EXIM), for example, can offer direct loans to foreign buyers alongside its guarantees. Germany's system, managed by Euler Hermes on behalf of the federal government and colloquially known as "Hermes Cover," primarily relies on "pure cover"—providing the insurance policy while private banks provide the actual capital.[2]

For decades, this system operated quietly in the background of global trade. But as the climate crisis has escalated, ECAs have become a primary battleground for environmental policy. Because ECA guarantees put taxpayer money on the line, watchdogs argue they constitute a form of public subsidy for the fossil fuel industry.[3][4]

In November 2021, 40 nations and institutions signed the Clean Energy Transition Partnership (CETP) in Glasgow. The signatories, which included Germany, pledged to end international public finance for fossil fuels by the end of 2022 and fully prioritize clean energy. The commitment explicitly covered export finance via ECAs.[3]

The agreement has driven a massive shift in capital allocation. According to a recent analysis by the International Institute for Sustainable Development and Oil Change International, international public finance for fossil fuels from CETP signatories dropped by 78% in 2024 compared to pre-alliance levels.[3]

However, the transition has not been absolute. The same report found that ECAs accounted for 72% of the remaining fossil fuel finance approved by signatories. Exceptions carved out for "security of supply" have allowed certain gas projects to proceed, as demonstrated by the German backing of the Herrenknecht rig in Brazil.[3][4]

Policymakers defend these carve-outs as necessary transitional measures, arguing that abruptly cutting off all export finance for natural gas could destabilize energy grids in developing nations and cede strategic trade relationships to countries without climate commitments. They also note that strict environmental and social governance (ESG) standards are increasingly applied to every approved transaction.[1][5]

Simultaneously, ECAs are being retooled to serve as the financial engine for the green transition. Agencies are rolling out specialized products to incentivize renewable energy exports. Sweden's EKN, for instance, now offers a "green export credit guarantee" that can insure up to 100% of a transaction's value if it contributes to the climate transition.

Germany's Euler Hermes has similarly introduced attractive cover improvements for sustainable projects, extending financing terms up to 22 years and increasing the cover ratio for political and economic risks. By absorbing the risk of deploying new, capital-intensive green technologies in emerging markets, ECAs are attempting to accelerate global decarbonization.[1]

The dual role of export credit agencies—winding down legacy fossil fuel commitments while scaling up green infrastructure—highlights the friction inherent in the energy transition. As governments rewrite the rules governing these state-backed guarantees, the obscure committees that approve them will continue to dictate the pace and shape of global development.[5]
