Could climate change trigger a financial crisis? - The Economist
The clearer governments are about emissions reduction, the less likely financial turbulence becomes
I N RECENT YEARS regulators have begun warning about the threat that climate change poses to the stability of the financial system. Following its strategy review in July, the European Central Bank (ECB) will assemble a “climate change action plan”. Mark Carney, the former governor of the Bank of England, warned of financial risks from climate change as long ago as 2015. In America the Commodity Futures Trading Commission last year published a 200-page report beginning “Climate change poses a major risk to the stability of the US financial system.” But progressive Democratic politicians are calling on President Joe Biden not to reappoint Jerome Powell as the chairman of the Federal Reserve, partly because they think he has done too little to eliminate climate risk.
Just how damaging does climate risk stand to be, though? Early stress tests by central banks and disclosures of companies are starting to shed light on the question. For the most part, the evidence that it could bring down the financial system is underwhelming. But a lot hangs on whether governments set out a clear path for reducing emissions, such as through carbon taxes and energy-efficiency standards, giving banks enough time to prepare.
