The rising cost of insuring against the climate crisis is a pressing issue that will have far-reaching consequences for the UK economy. While the immediate effects are felt through lost productivity and disrupted daily life, the long-term implications are even more concerning. The insurance sector, a vital component of the financial system, is struggling to keep up with the increasing frequency and severity of extreme weather events. This struggle has a knock-on effect on the wider economy, as the financial lobby group TheCityUK and economist Swati Dhingra have highlighted.
TheCityUK's report, in collaboration with insurer Marsh, emphasizes the challenge of insuring homeowners and businesses against extreme weather. As climate hazards intensify, traditional actuarial methods for insurance pricing become less reliable, leading to "protection gaps" where homes and livelihoods remain uninsured during natural disasters. This is a tragic outcome, but it also underscores the importance of insurance in facilitating investment. The report warns that the difficulties in pricing climate risk are not just a sectoral issue but a fundamental concern for the stability of the financial system.
The unpredictability and severity of weather events are likely to have broader economic repercussions. TheCityUK's report suggests that this could create a vicious cycle. Insufficient investment in climate adaptation may increase the cost of climate damage, which in turn raises the cost of investment as insurers and lenders recoup their losses. This highlights the need for more public or partially public backstops to support the private sector in addressing climate resilience.
Dhingra's speech further emphasizes the impact of adverse weather events on UK inflation. For instance, extreme heat in West Africa led to a surge in cocoa prices, contributing to a 1 percentage point increase in UK food inflation in 2025. The Energy and Climate Intelligence Unit (ECIU) analysis revealed that 13% of UK food imports last year originated from the least climate-resilient countries, exposed to extreme weather. This includes rice from India, fruits from South Africa and Egypt, coffee from Vietnam and Brazil, and bananas from Colombia and Ecuador. While these price increases may seem minor, they reflect the harsh realities faced by agricultural laborers in vulnerable regions, who lost billions of hours to heat stress in 2024.
The Bank of England's Monetary Policy Committee (MPC) plays a crucial role in responding to these economic shocks. However, Dhingra argues that raising interest rates to combat inflationary impacts also increases the cost of borrowing for much-needed investments in the net zero transition and climate adaptation. Similarly, using higher rates to manage energy price volatility could hinder investment in renewable alternatives, which are essential for UK energy security. This highlights the need for a more integrated approach between monetary policy and government tax and spend policies to break the vicious cycle.
Dhingra suggests that governments should be prepared to provide targeted support measures to cushion consumers against repeated shocks, allowing the Bank to focus on broader economic stability. This might involve targeted subsidies, price controls, or temporary tax measures. In the current era of frequent economic shocks, politicians are becoming more comfortable with market interventions that were once taboo. As Andy Burnham's political ambitions gain momentum, his early decisions will likely involve managing the impact of the Middle East crisis on energy bills and protecting the green transition.
In conclusion, the rising cost of insuring against the climate crisis is a complex issue with far-reaching implications. It requires a multifaceted approach, involving both private and public sectors, to address the challenges and ensure a sustainable economic future for the UK.
