An extensive review of climate change and the risks to financial stability by Tailrisk Economics found very little evidence that climate change will have a systemic impact on financial systems in advanced countries. Most of the claims that floods, storms fires and sea level rise will generate system level risks are not based on serious analysis and proper stress tests by overseas banks are showing that losses will be very low.

“The Reserve Bank of New Zealand’s recent claims that climate change poses a systemic risk to the financial system is an overreaction” said Ian Harrison principal of Tailrisk Economics “motivated more by attention seeking than the science and sound economics”.

New Zealand is relatively well placed to manage physical climate change risks. The economy is more likely to benefit than lose from climate changes over this century. A recent NIWA study shows that flooding risk will actual fall and while sea level rise may be a challenge in some places, banks are well placed to manage the risks to their balance sheets.

“Our analysis confirms the findings in an internal Reserve Bank report written in 2018.” Harrison noted “But the Reserve Bank deliberately hid their report for months and misled people seeking it under the Official Information Act, to promote its new more catastrophist narrative”

“The Tailrisk review was written before the Reserve Bank released its ‘Climate Changed 2021 & Beyond’ paper, but a quick review found the paper lacked any serious analysis of the of impact of climate change on the financial system.

“The Bank’s role on climate change should be to keep a watching brief and to hose down uninformed inflammatory catastrophist stories about financial system risk, not to create them” Harrison said.
