Coastal DevelopmentThe MAR+Invest Guarantee Fund represents a pivotal innovation for unlocking sustainable investment in the Mesoamerican Reef (MAR) region. Designed to de-risk investments in reef-positive businesses, the Guarantee Fund addresses a key challenge in the region: limited access to capital for early-stage or high-impact ventures that are not yet fully investment-ready. By providing financial security and enhancing investor confidence, the fund plays a critical role in enabling the deployment of blended finance products.
Officially launched in June 2024 with an initial transfer of US$250,000—followed by a second transfer bringing the total to US$500,000—the fund is housed in a dedicated JP Morgan account . Viwala, the financial intermediary for MAR+Invest, is responsible for analyzing investment opportunities, managing concessional loans, and recommending the use of the guarantee fund for eligible reef-positive ventures, in close coordination with MAR Fund.
By 2025, the guarantee fund has been leveraged in two deals: a blended finance loan for Terminator Water Solutions and for Chiringuito Hotel.
