Frank Elderson speaks with the quiet conviction of a man who has seen the numbers. As a member of the executive board of the European Central Bank, his office isn’t far from mine here in Lower Manhattan, but his view of risk spans an entire continent. When he tells me that the climate and nature crises represent a dramatically growing risk to the global economy, I hear the sober analysis of a central banker, not an activist. This is the language of collateral, not carbon credits. His warning, delivered in an interview before this summer’s devastating European wildfires, cuts through the market noise with chilling precision. We are no longer measuring risk in basis points, but in degrees Celsius and hectares lost.
The ECB, as the eurozone’s lender of last resort and supervisor of its largest banks, is now explicitly monitoring the financial risks tied to the destruction of what it terms ecosystem services. Elderson, a Dutch lawyer who was instrumental in founding the global Network for Greening the Financial System, defines these services as any benefit drawn from nature—from water for hydropower and transportation to soil for agriculture and forests for carbon sequestration. “These services are not stable but they are in rapid decline,” he states. The dependency of our economic machinery on these services is absolute, and as they fray, so too does the foundation of credit, growth, and price stability the ECB is mandated to protect.
This is a profound shift in risk modeling. For years, financial stress tests focused on capital ratios and non-performing loans. Now, the ECB is building frameworks to assess how “ecosystem degradation pathways” could translate directly into credit losses for major banks. Imagine a Spanish bank with a concentrated loan book in agricultural regions facing persistent drought. Or a French insurer seeing claims skyrocket from floods and fires. The direct economic cost of this summer’s fires across Southern Europe will be staggering, a line item in national budgets and corporate earnings reports for quarters to come. But Elderson points to a more insidious, slower-burning risk: the collapse of the natural systems that underpin entire sectors. Mapping reliance on a single hurricane is one thing; quantifying the systemic risk from the incremental loss of pollination, water purification, or coastal storm buffering is exponentially more complex.
The data emerging supports this heightened vigilance. A 2023 report by the Network for Greening the Financial System, which now includes 114 central banks and supervisors, concluded that nature-related risks are material to both macroeconomic and financial stability. The European Environment Agency has consistently documented the accelerating decline of ecosystem services across the continent. This isn’t speculative. It’s observed, measured, and now being factored into the most conservative of institutions: the central bank.
Elderson is keen to separate this from any political agenda. “This is not some kind of a flower-power, tree-hugging exercise,” he emphasizes. “This is core economics. This is core financial stability, core price stability.” His point is tactical. When the core mandate of an institution charged with preserving the value of the euro is threatened, it must act. The pushback against integrating climate risk, notably from parts of the U.S. financial system following its withdrawal from the NGFS last year, is viewed in Frankfurt as a failure of risk management, not a political disagreement. “I would think it’s very difficult to find a bank in Europe that will honestly tell you that they think this is not relevant,” Elderson notes. “I think that time has passed.”
From my desk overlooking the Financial District, the implications are clear. The ECB’s stance signals that a fundamental repricing of assets is inevitable. Sectors with high dependency on stable ecosystem services – agriculture, real estate in vulnerable coastal zones, tourism, and even utilities – face a future where their risk profiles are permanently altered. Banks will be forced to adjust their lending practices, and insurers their premiums. This will create winners and losers, redirecting capital flows. The ECB’s planned analysis later this year on how nature degradation translates to bank credit losses will be a must-read document for every portfolio manager and CFO on this side of the Atlantic.
The climate crisis has moved from the CSR report to the 10-K filing. Elderson and the ECB are formalizing that transition. They are arguing, with the full authority of their position, that destroying nature is akin to destroying the underlying collateral for the entire global economy. In finance, when your collateral deteriorates, the entire deal collapses. That’s not activism. That’s just accounting. And in the high-stakes world of central banking, it’s the only math that ultimately counts.
- Climate and nature crises as growing risks
