Climate change, sovereign debt and the looming debt crisis in the global south

Updated Monday, 25th July 2022

The countries that contribute the least to climate change are facing the greatest financing difficulties in addressing its impacts. What do we know about how climate change will affect the macroeconomy?

This content is associated with The Open University's Economics courses and qualifications.



What is the impact of climate risk on financial sector stability? Will countries facing the greatest climate risks also face the steepest rise in cost of public borrowing?

Learning outcomes

After exploring the seminar material, you will be able to discuss challenges of mobilising finance for a sustainable transition. You will learn about the dangers of a vicious circle between climate vulnerabilities, cost of capital and rising fiscal vulnerabilities.

Climate change, sovereign risk and the cost of capital

Ulrich Volz, Professor in Economics at SOAS (School of Oriental and African Studies), explained that there is a danger that vulnerable developing countries will enter a vicious circle in which greater climate vulnerability will raise the cost of debt and diminish the fiscal space for investment in climate resilience.

He explores the link between climate change and sovereign risk and assesses the effects that climate risks have on the cost of government debt. Enhancing economic resilience and climate-proofing public finances is needed to address the looming debt crisis in the global south. One of the ways proposed to deal with these problems is debt relief targeted for green and inclusive recovery that will empower governments to invest in climate resilience and other strategic areas of sustainable development.

Governments must climate-proof their economies and public finances, or they will potentially face an ever-worsening spiral of climate vulnerability and unsustainable debt burdens.

What should inclusive and green recovery policies look like?

Elva Bova is Deputy Head of the National Fiscal Frameworks and Institutions Unit in the European Commission’s Directorate General for Economic and Financial Affairs (DG ECFIN). From 2010 to 2016, she was an Economist at the International Monetary Fund (IMF) in the Fiscal Affairs Department.

Prior to joining the IMF, she obtained her PhD from the School of Oriental and African Studies, University of London. She has published on public finance, inequality and labour market.

In the video below, Elva explores the direct and indirect fiscal impacts that climate change may have. A number of policy priorities are discussed:

  • Integrating climate risks into debt sustainability analysis.
  • Greening fiscal budgets: how can fiscal policies help achieve environmental goals?
  • EU Green Bonds: voluntary standards for bond financing.
