MIGA Issues $639 Million in Guarantees to Santander to Unlock Climate and Inclusion Lending in Colombia and Uruguay

The Multilateral Investment Guarantee Agency has issued $639.3 million in combined capital optimisation guarantees to Banco Santander, enabling the bank to free up capital for new lending to microenterprises, electric vehicle buyers and sustainability-focused projects across Colombia and Uruguay. The guarantees work by optimising the capital treatment of mandatory reserve requirements held with host-country central banks, unlocking new lending capacity without requiring additional capital from Santander. The transaction includes MIGA's first capital optimisation guarantee in Colombia for $100 million, enabling $59 million in new loans to rural microenterprises, and a renewal of an existing $539.3 million guarantee in Uruguay supporting Santander's target of issuing $300 million in climate finance by December 2028.

 

The Colombia Guarantee and Its Development Impact

 

The $100 million Colombia guarantee will direct 68 percent of the unlocked $59 million in new lending to microenterprises in rural areas, with a particular focus on women-owned businesses, alongside 32 percent for financing electric and hybrid vehicles. This allocation reflects two of Colombia's most pressing development challenges simultaneously: financial inclusion for micro, small and medium enterprises that contribute 40 percent of GDP and generate 80 percent of employment but face an estimated financing gap of 14 percent of GDP, and acceleration of transport electrification as part of the country's carbon neutrality goal for 2050. Colombia's National Administrative Department of Statistics reports that 35.4 percent of the country's microenterprises are owned by women, making gender-focused rural lending a direct response to a documented structural financing gap.

Ariane Di Iorio, Director of the Financial Institutions Group at MIGA, said smaller businesses in rural Colombia have historically been overlooked by the financial services sector and that the country's electric vehicle loan market, while fast-growing, remains nascent. She said MIGA is delighted to partner with Santander on these capital optimisation guarantees, which unlock capital to address key development challenges. The Colombia transaction marks a significant first for MIGA's capital optimisation guarantee product in the country, establishing a precedent that could support similar structures with other financial institutions seeking to expand development-oriented lending beyond their existing capital constraints.

The Uruguay Renewal and Climate Finance Targets

 

The $539.3 million Uruguay guarantee is a renewal of an existing facility under which Santander Uruguay has already disbursed capital freed up by previous guarantees across a range of sustainability-focused projects including green transportation, clean energy, climate-smart agriculture and sustainable construction. The renewed guarantee is expected to enable new lending of $163.6 million and directly supports Santander Uruguay's ambition to issue $300 million of climate finance by December 2028. Uruguay is identified as particularly vulnerable to climate shocks that affect not only lives and livelihoods but also economic growth, inflation and the country's current account, making climate finance a development finance priority with macroeconomic as well as environmental dimensions.

Oscar Moseley, Head of Private Credit Insurance at Banco Santander, said the transactions are a strong example of how Santander can use innovative risk transfer solutions to deploy capital more efficiently while supporting financial inclusion, climate finance and sustainable growth across Latin America. The renewal structure demonstrates how capital optimisation guarantees can be used on a sustained basis to maintain and grow a bank's development lending capacity over time rather than as a one-off instrument. The combination of an inaugural Colombia guarantee and a Uruguay renewal within the same transaction illustrates how MIGA is scaling this product across multiple Latin American markets simultaneously.

 

The Capital Optimisation Guarantee Mechanism

 

Capital optimisation guarantees function by improving the regulatory capital treatment of assets held by commercial banks, allowing them to hold less capital against specific exposures and thereby freeing resources for new lending. In the context of mandatory reserve requirements held with host-country central banks, MIGA's guarantee provides the risk mitigation that enables improved capital treatment, creating new lending capacity without requiring Santander to raise additional equity capital or reduce existing loan portfolios. This mechanism makes development finance considerably more capital-efficient than direct balance sheet lending and can be deployed at significantly greater scale relative to the guarantee capital committed.

The World Bank Group Guarantee Platform, initiated in 2024 and hosted at MIGA, has set a target of boosting annual guarantee issuance to $20 billion by 2030 through consolidated guarantee products and streamlined processes. The Colombia and Uruguay transactions with Santander represent the type of scalable, repeatable capital optimisation guarantee structures that can contribute meaningfully to this target while mobilising private commercial bank capital for development purposes. The platform's goal of simplifying access to guarantee instruments and removing redundancies across the World Bank Group creates the institutional infrastructure needed to accelerate this model across developing country markets.

Outlook for Capital Optimisation Guarantees in Latin American Development Finance

 

The MIGA and Santander transactions demonstrate that capital optimisation guarantees can effectively bridge the gap between commercial bank capital constraints and development finance needs in emerging markets, particularly where financial inclusion and climate finance require lending that traditional risk-return frameworks do not readily support. As Latin American economies face growing financing gaps for climate adaptation, women's economic empowerment and small business development, instruments that multiply the development impact of each dollar of guarantee capital will become increasingly important. The scalability of the capital optimisation model, which can be renewed and expanded as demonstrated by the Uruguay transaction, makes it particularly suited for sustaining long-term development lending programmes.

Whether MIGA and Santander can demonstrate meaningful impact on financial inclusion and climate outcomes in Colombia and Uruguay through sustained monitoring and transparent reporting will determine the credibility and replicability of this guarantee structure. Continued execution would strengthen the case for expanding capital optimisation guarantees to additional Latin American markets and financial institutions, accelerating the region's access to the development and climate finance needed to meet its ambitious economic and environmental goals. The alignment of financial inclusion, gender finance and climate finance within a single guarantee structure also provides a model for integrated development finance that addresses multiple SDG objectives simultaneously.
