Climate resilience is high on the agenda, but it’s insufficiently understood. While resilience language has entered climate policy, development debates, and financial conversations, the flow of finance hasn’t. More money is mobilised after disasters for relief, recovery, and reconstruction, while far less is directed before disasters strike to build long-term resilience.
This is a myopic view of economic return — where every investment is judged through immediate revenue or rates of return. But resilience finance cannot be understood only through this narrow logic. Its value lies in avoided losses, saved lives, protected livelihoods, reduced future costs, and the preservation of development gains. Financing resilience therefore needs to be decoded, understood, and implemented as an economic, social and developmental necessity — not merely as a budget line within climate finance.
The key challenge is to move finance from response to readiness. From reactive to proactive.
This requires a shift in thinking about climate resilience. Resilience is a development question, an economic question, a fiscal question, and increasingly, a question of competitiveness and social stability. Climate shocks are shaping food prices, public expenditure, infrastructure planning, insurance markets, health systems, migration patterns, and investment decisions.
The case for resilience finance is not only moral. It’s economic. It’s practical. And it's urgent.
Financing resilience is becoming a form of long-term economic protection. It’s the investment we make today to avoid deeper losses tomorrow.
This is especially important because resilience investments are often misunderstood. A road that can withstand flooding, a city that tackles heat stress, a farmer who has access to drought-resistant systems, a coastal community protected by mangroves, or an early warning system that saves lives may not always generate visible revenue. But they generate enormous social and economic value by preventing loss, reducing disruption, and protecting development gains.
The challenge is that our financial systems are still better at pricing damage than at valuing resilience. We know the cost of a destroyed bridge or a failed harvest. But we are much less effective at calculating the value of the bridge that did not collapse, or the crop that did not fail saving communities from starvation.
This is why resilience needs a new language: the language of avoided losses, reduced future costs, protected livelihoods, and sustained development.
This view is being echoed across the world. At the Resilience Finance Summit by IIED during London Climate Week, H.E. Mehmet Şimşek, Minister of Treasury and Finance, Republic of Türkiye, spoke of resilience as an economic necessity. That framing is important as it moves resilience from the margins of climate policy to the centre of economic management.
Inflation is directly linked to climate shocks such as drought. When drought affects crops, food prices rise. When extreme weather damages infrastructure, public expenditure increases. When heat affects workers, productivity falls. Climate shocks move through the economy in ways that are direct, measurable, and increasingly difficult to ignore.
Yet the scale of available finance remains deeply inadequate.
Minister Şimşek noted that against a need of around US $2.24 trillion per year, only about US $200 billion per year is available. But he also made a crucial observation: the issue is not simply a shortage of global capital; it’s also about shaping resilience priorities into investible projects.
This is one of the most important barriers we must address. Vulnerability is widespread, but that notion alone does not automatically attract finance. Money won’t come without credible pipelines of projects: projects with clear objectives, institutional ownership, measurable benefits, capacity, and appropriate financing structures.
Resilience finance is about changing what counts as value, what kinds of projects are considered investible, and how quickly finance can reach the countries, communities, and institutions that need it most.
Not all resilience fits into commercial models. Many essential investments, especially those that protect the poorest and most exposed communities, will need public, concessional, grant-based, or blended finance. We need a stronger link between climate risk and actual financial flows.
For developing countries, this challenge is even more urgent. Seasons are shifting, and with them the foundations of agriculture, water planning, health preparedness, and livelihoods. Many countries know they need to invest in resilience, but the cost of capital makes such investment difficult. The willingness to act exists.
The responsibility to protect people exists. But the financial terms are often prohibitive.
When the pace and scale of international climate finance are too slow, and the uptake of resilience solutions limited, countries face a double burden: rising climate vulnerability on one side, and inadequate access to affordable finance on the other.
That’s why resilience finance urgently needs to be designed differently. It must recognise debt burdens. It must use concessional finance more strategically, and expand guarantees, risk-sharing instruments, and local-currency solutions. It needs to empower local governments and communities, and it must prevent the most-vulnerable to climate impacts being left with the bill.
A key question is: how do we price climate risks? Linda Freiner, Group Sustainability Officer at Zurich Insurance Group, spoke of how markets are good at valuing loss and damage after a climate disaster, but not at valuing how the losses can be avoided through prior investment in resilience.
Inaction will not save money, but rather push risk into the future where the cost of reducing risk becomes even higher, she said. Resilience investments may not produce direct revenues, but they reduce future costs by protecting assets, supply chains, public budgets and key infrastructure.
The future of climate finance must therefore be forward-looking. It must reward prevention, not only compensate loss. It must value avoided damage, not only visible reconstruction. And it must help countries to turn resilience from ambition into implementation.
