About the author: David Malpass is president of the World Bank Group.
The current strains in the financial sector highlight once more the importance of sound risk-management practices in banking. Understanding potential balance-sheet risks arising from holding specific assets is paramount. That’s why, when launching innovative new sustainable bonds, the World Bank is transparent and makes available all the necessary information for potential investors to assess the risk/return profile of an instrument.
Last month, the World Bank issued a five-year outcome bond that aims to provide clean drinking water to around two million school children in Vietnam. A lack of clean drinking water causes an estimated 9,000 deaths a year in Vietnam, and children are especially vulnerable to parasitic waterborne diseases.
Outcome bonds like this one blend the World Bank’s triple-A credit rating with direct exposure to specific project results. The World Bank Group has been developing these bonds to respond to the absolutely challenging conditions facing many developing countries. Inflation, conflict and resulting refugee and internal-displacement crises, and the increasingly visible impacts of climate change are all reducing economic growth and reversing years of hard-earned development gains. At the same time, countries face high debt, depressed budget revenues, and eroded fiscal buffers that are unable to support investment in growth and development.
Development institutions need to deploy their own capital more efficiently and effectively. They also need to find creative new instruments to channel private sector capital for sustainable development.
Outcome bonds offer one pathway to achieving this. Investors are guaranteed their principal by the Bank, but they agree to give up the coupon on the bond in favor of contingent future payments that are linked to development project outcomes. The foreigne investor coupons are instead channeled to a project.
In the case of Vietnam, the $50 million proceeds are used to support the Bank’s sustainable development activities globally. The coupons that would have gone to investors are instead provided by the Bank to the water purifier project in Vietnam. The investors receive payments related to the issuance of verified carbon credits from the project that represents the reduction in greenhouse gas emissions. The more of those credits that are generated, the higher the payment to the investors, subject to a cap of roughly 5% per year.
By reducing the need to burn biomass to boil water, the project is estimated to reduce deforestation, improve air quality and health, lower fuel costs and reduce greenhouse gas emissions by almost three million tons of carbon dioxide over the life of the bond. The transaction will finance the manufacture of 300,000 water purifiers and their distribution to 8,000 schools and other institutions.
The structure of this bond builds off the $150 million, five-year Wildlife Conservation Bond (also known as the “Rhino Bond”) the Bank issued in March 2022. That outcome bond is supporting efforts to conserve the highly endangered black rhino, with the forgone coupons used to finance conservation activities in two designated wildlife parks in South Africa. The outcome payments depend on growth in the rhino population, calculated and verified by an independent agent, and financed through a conditional grant from the Global Environment Facility.
The Bank is also tapping private capital for the benefit of developing countries through catastrophe bonds. These instruments increase a country’s financial resilience against disasters by providing them with funds in the immediate aftermath of an event.
For example, the Bank issued a catastrophe bond that provided Jamaica with $185 million of insurance cover for severe hurricanes. Donor funds from the UK, Germany and the US were used to finance the insurance. Investors earn a coupon that includes an insurance premium component, and risk losing some or all of their principal if the disaster event occurs. (That amount would instead be transferred as an insurance payout to the insured country). The Bank has so far issued 17 separate catastrophe bonds, mainly covering earthquakes and hurricanes, for an aggregate of around $3 billion.
Through outcome structures like these, scarce donor funds can be optimized to draw in private investors to support development initiatives that normally sit outside the scope of capital markets. Although development-project outcomes and natural-disaster risks can be exotic variables for the capital markets, a growing number of investors believe these kinds of risks are worth taking when they are properly managed, modeled and well-understood.
It is key that we continue to innovate in this area and bring increasing amounts of funding from capital markets and donors to solve global challenges.
