Water, finance, and the power of systems thinking

In Madrid this May, World Waternet joined two major conversations on the future of water: the Global Water Summit and the Organisation for Economic Co operation and Development (OECD) Roundtable on Financing Water at the Banco de España. What we found was not a sector searching for relevance. Instead, it is a sector at a turning point. New thinking, new financial models and new political attention are starting to come together. Delivering the Water Transition requires systems thinking and collaborative action – moving beyond traditional norms. Madrid made one thing clear: water is moving to the centre of how we think about resilience, growth and global stability. 

The intellectual backbone 

A big part of this shift comes from the Global Commission on the Economics of Water. Its landmark report argues that the hydrological cycle should be valued as a global common good. Because if we keep treating water as an afterthought, we are not heading towards a resilient future, but towards a far more fragile one. That matters because the global water crisis is no longer just a water sector issue. It affects food, public health, economic growth, displacement and financial stability. The report makes the case for seeing water as a systems issue and for acting across five connected missions, from food systems and ecosystems to circular water use, clean energy and safe water for children. For World Waternet, this is highly relevant. Our work in Water Operators’ Partnerships connects directly to this agenda, since our integrated water cycle approach speaks to all five missions.  

The new operational engine 

Just weeks before Madrid, on 15 April 2026, the World Bank Group launched the Water Forward initiative at its Spring Meetings in Washington. This new initiative aims to improve water security for one billion people by 2030. Its main delivery model is the country-led Water Compact. These compacts are designed to bring policy reform, stronger institutions and investment planning together in one framework. Fourteen countries joined the first wave. For World Waternet, this is not abstract. Kenya and Jordan, where we already work through Water Operators’ Partnerships, are part of this first group. That is important. It suggests that countries where utility partnerships have already helped build capacity are now stepping forward into larger national reform processes. 

Water Forward also uses a language that is becoming more common across the sector: water as a driver of jobs, productivity, resilience and investment. This is also a strong reminder that while the water agenda is a global ambition, the implementation of the water transition requires local action, working together with a diversified pool of stakeholders and providing concrete evidence of positive effect in consistence ways. 

What we heard in Madrid 

The message in Madrid was clear. There is not one water transition, but five that need to happen at the same time. We need to move from:

• A linear water economy to a circular one
• Outdated to Smart infrasturcture; powered by clean energy, data, and innovation.
• Grey to Green infrasturcture. We need to integrate nature in our water management.
• A competitive system to a collaborative one. Water does not stop at borders, we need to unite in implementing transboundary water governance models.
• Subsidies to Sustainable Financing. We need utitlities that are creditworthy, and recover their operational costs in full with fair pricing.

The Organisation for Economic Co-operation and Development (OECD) roundtable reinforced another important point. Water is now seen as a channel for financial risk. That means central banks, public finance institutions and investors have a real role to play. The issue is not simply a lack of money. It is a lack of alignment between finance, institutions and delivery.
