A country’s assets are not the only kind of flows monitored by sovereign investors – abundant water supplies are also critical to well-functioning economies. Extreme water stress can disrupt domestic industries, increase government costs, and trigger social unrest – key concerns of sovereign bond investors.
Water stress – which happens when water demand exceeds supply – is on the rise globally. Though it can stem from natural causes (e.g., droughts and seasonal rainfall variations), over-extraction, pollution, and inefficient water use by populations and industries are also major drivers.
Water is disproportionately used in agriculture, but it is also essential for many other sectors including energy and textiles. As industries and populations grow, water scarcity and stress levels will continue to rise, and with them the cost of securing water supplies by companies and governments. Climate change will further exacerbate the problem.
Prolonged water stress can also lead to social instability if supplies to hospitals and households are disrupted, endangering public health. Given water stress is a multi-faceted problem, the Robeco Country ESG Framework has consistently used many water-related metrics to track and understand changes in country water supplies and their subsequent impact on public financing and future economic growth.
