A key common feature of the global climate crisis and the Global Financial Crisis (GFC) lies in destabilising feedback loops. This column identifies and compares these highly non-linear processes, with lessons for policymakers and modellers. The cascades and contagion of the financial accelerator have climate parallels. Absent decisive action, accumulating greenhouse gases, in raising global temperatures, will lead to more carbon release and even higher temperatures, ultimately rendering much of the planet uninhabitable. Russia’s war creates immediate separate crises for the financial and global climate systems. By delaying approaches to net zero, their linkages increase future financial stability risks.

The collapse of global trade during the COVID-19 crisis was stunning in its magnitude, but was milder in relative terms than during the Global Crisis. Based on data from 40 different countries, this column suggests that the key lies in the composition of demand. The contributions of consumption and services sector demand to the import contraction were notably larger during the COVID-19 crisis. This may have led to a relatively milder import contraction, as consumption and services production are less import-intensive than investment and manufacturing production.

When we live through a financial crisis, many of us think differently about money afterwards. Neuroscientists can show that the experience changes the physical structure of our brains, and Ulrike Malmendier tells Tim Phillips how this should also change the way that economists think about preferences for risk.

Following the global financial crisis, subnational governments engaged in pro-cyclical fiscal policy by reducing investment, drawing out the recovery. This column presents evidence suggesting that the Covid crisis has impacted the fiscal positions of subnational governments in the OECD far less than the previous crisis, which should mitigate this tendency towards pro-cyclicality. This is partly the result of central governments having provided substantial fiscal support, while at the same time subnational governments have relied heavily on relatively stable revenues from recurrent taxes on immovable property which, unlike in the previous crisis, are not expected to decline due to a housing market crash.
