- Senior insurance industry whistleblowers warn that rising climate-related losses and declining insurance availability could create systemic financial risks comparable to the 2008 mortgage crisis.
- An industry insider claims the UK’s Flood Re scheme may lack sufficient funding to cover losses from a major flooding event as extreme weather risks increase.
- Insurance professionals identify fossil fuel companies as the leading candidates to bear climate damage costs, while insurers increasingly transfer financial exposure to homeowners and governments.
Senior insurance industry executives have warned that climate change could trigger a global financial crisis as insurers withdraw coverage from high-risk properties, increase premiums and transfer growing financial losses to homeowners and governments.
In an open letter coordinated by UK-based campaign group Inside Track, industry whistleblowers argue that the declining availability of property insurance could destabilize mortgage markets and create systemic economic risks comparable to those preceding the 2008 global financial crisis.
The warning follows widespread storm and flood damage across the UK last year, with communities in flood-prone areas preparing for further severe weather during the autumn and winter.
Scientists have established that fossil fuel emissions drive global warming, contributing to increasingly severe weather events. As the resulting financial losses increase, insurers are reassessing their exposure to flooding, wildfires and other climate-related hazards.
Some companies are raising premiums to levels that homeowners cannot afford, excluding specific risks from policies or withdrawing coverage entirely from particularly vulnerable locations.
The executives warn that these developments could have consequences extending beyond the insurance industry.
We are worried a major increase in uninsured, high-risk properties could manifest in a similar way as climate impacts intensify,” the signatories wrote, referring to the collapse of the US subprime mortgage market that helped trigger the 2008 financial crisis.
“These are not just risks that will affect some of the population, they are fundamental and systemic economic risks.”
Journalists who spoke with several of the executives behind the letter verified their identities. The insiders emphasized that climate-related insurance problems are already affecting underwriting decisions rather than representing a distant financial threat.
Property insurance plays an important role in mortgage lending because lenders generally require borrowers to maintain adequate coverage.
If insurance becomes unavailable or prohibitively expensive across large numbers of properties, the executives fear the resulting pressure on property values and mortgage financing could spread through the financial system.
Their letter identifies the possibility of economic disruption resembling the conditions that preceded the subprime mortgage crisis.
Concerns also extend to the financial capacity of existing insurance arrangements designed to protect households in flood-prone regions.
Flood Re, a UK government and insurance industry-backed scheme, was established to help maintain access to affordable flood insurance in areas exposed to repeated flooding.
The arrangement is funded through a levy on UK home insurance policies, creating a pool of money that participating insurers can use to support coverage of flood-related claims.
An industry insider with specialist knowledge of Flood Re warned that the scheme may not have sufficient funds to meet losses from a major flooding event.
The executive argued that this vulnerability is becoming more serious as climate change increases the likelihood of severe flooding.
The whistleblowers also warned that insurance market withdrawals would increase the volume of uninsured losses, leaving other parties responsible for financing recovery and repairs.
Without insurance protection, the financial responsibility for repairing future flood damage to those properties will fall on local authorities.
The executives caution that public finances may be unable to absorb such liabilities indefinitely, particularly if multiple costly weather disasters occur within a short period.
Allianz has warned that governments could face severe financial consequences if repeated climate-related disasters generate losses beyond their capacity to provide assistance.
Governments confronting several expensive disasters in rapid succession could be forced into austerity measures or face financial collapse.
When insurance professionals were asked who should bear these costs, their most common answer was fossil fuel companies, whose products contribute to the emissions driving climate change.
The whistleblowers’ central concern is that the financial burden of climate-related damage is increasingly moving outside the insurance market, exposing homeowners, local authorities and national governments to losses that may become difficult to finance.
As insurance protection declines in vulnerable areas, the executives warn that the consequences could extend into mortgage lending, property markets and the wider financial system.
