The impact of the pandemic and the credit crisis which has resulted have the ability to create a financial catastrophe as the impact of climate change grows.
Researchers at Oxford University have warned that most governments’ “astronomical borrowing” during the pandemic pays scant attention to the effects that climate change could have on their ability to repay the debt.
They estimate that $783 billion has been borrowed from the private sector through sovereign bonds that mature 30, 50 or 100 years from now. However, 77% of countries have not disclosed the risks they face due to climate change in this same time period, in a world projected to face growing climate impacts. This lack of disclosure could lead to a severe debt crisis. Over the 30 to 50-year period covered by much of the COVID-19 lending, changes in global average temperatures alone could cause GDP to drop by tens of percentage points in some countries.
“The gaps we found suggest that governments do not understand the economic impacts of climate risks or are unwilling to report them. Both explanations are troubling… Without rigorous climate disclosures, investors and governments are flying blind,” stated the authors. The research cites the example of Saudi Arabia’s bonds, which will mature in 2060. At this point, lower productivity and higher mortality due to a more extreme climate could cause a 60% drop in GDP.
“Estimates like this are likely to be conservative, the authors warn, because they do not account for extreme weather events,” warned the report, National COVID debts: climate change imperils countries’ ability to repay. “When Hurricane Maria hit Dominica in 2017, it caused damage worth an estimated 220% of GDP.”
Severe climate shocks, or even the anticipation of them, could cause government defaults (where governments are unable to repay their debt) and a credit crisis. This could lead in turn to higher borrowing costs for vulnerable governments, exclusion from commercial debt markets and the withdrawal of investors, just when the country needs more external capital to respond to the climate crisis, the authors added.
Thom Wetzer, Associate Professor of Law and Finance and Director of the Oxford Sustainable Law Programme explained: “The COVID, climate, and credit crises compound in ways that could create a financial catastrophe during the peak of the climate crisis. This study is a call to action. Countries should transparently disclose climate risks, use the COVID-19 recovery to build climate resilience, and support the most vulnerable borrower countries. It is imperative that we do not leave this burden to future generations – by that time it will be too late.
“Countries may struggle to pay back their rapidly rising debt because of the impact of climate risks on their economy. A failure to appreciate, disclose, and manage these risks today could cause serious problems in the future. Unlike companies, countries cannot simply seize to exist when bankrupt – their citizens will bear the cost of debt burdens for generations.”
The authors suggested three solutions to the oncoming debt crisis:
- Countries must work together to better assess, disclose and manage vulnerability to sovereign climate risk while developing new tools to deal with the non-linear and radically uncertain nature of sovereign climate risk.
- Governments should use COVID-19 credit to mitigate climate risk, build climate resilience and grow the economy to aid future debt repayment, living up to the promise to ‘build back better’.
- Wealthier lender countries and their development finance institutions (DFIs) should provide financial support to the most vulnerable borrower countries. DFIs should buy back debt from heavily indebted poorer countries, on the condition that the money is used to increase climate resilience.
Dr Arjuna Dibley, a Researcher at the Oxford Sustainable Law Programme, added: “There has been considerable discussion to date about ‘green’ spending by governments during the COVID-19 pandemic. Our research shows that it is not just the way governments spend money which matters for climate change, but also the way they raise such money from the capital markets can also have damaging climate and equity consequences. As citizens, we need to ensure our governments both raise and spend public money in ways that do not exacerbate the climate crisis.”
