Climate change is emerging as a foundational risk to the UK’s financial stability, threatening to undermine insurance markets and trigger persistent inflationary pressures. According to a report from TheCityUK and insurer Marsh, the increasing frequency of extreme weather is making it difficult for insurers to price risk, while Bank of England policymaker Swati Dhingra warns that relying on interest rates to combat climate-driven price shocks could stifle necessary investments in the net-zero transition.
Why is climate risk threatening the insurance sector?
Traditional actuarial models, which rely on the assumption that loss probabilities remain stable year-over-year, are failing as climate hazards intensify. TheCityUK reports that extreme weather events like wildfires and floods are becoming too unpredictable to model accurately. This trend creates “protection gaps,” leaving businesses and homeowners without coverage. Because insurance acts as a vital lubricant for investment, the inability to price these risks threatens the “bankability and investability” of the broader UK economy, according to the trade body.
How does climate change influence UK food prices?
The UK’s reliance on climate-vulnerable regions for food supplies creates a direct pipeline for inflation. An analysis by the Energy and Climate Intelligence Unit (ECIU) found that 13% of UK food imports last year originated from countries with low climate resilience. These imports include staples such as rice from India, coffee from Vietnam, and bananas from Colombia. The ECIU estimates that agricultural workers in the 15 most climate-vulnerable nations lost 216 billion hours to heat stress in 2024, a disruption that eventually manifests as higher prices on British supermarket shelves.
The ECIU notes that the 15 countries most vulnerable to climate change provided a significant portion of the UK’s soft fruit and tea supply, meaning local weather patterns abroad have a measurable impact on the cost of living in the UK.
Can monetary policy solve climate-induced inflation?
Bank of England MPC member Swati Dhingra argues that interest rates are a “blunt instrument” for managing climate-related shocks. While raising rates can help anchor inflation expectations, it simultaneously increases the cost of borrowing for companies attempting to invest in green infrastructure. Dhingra suggests that the government may need to take a more active role through targeted subsidies, price controls, or temporary tax measures to cushion consumers from shocks, allowing the Bank of England to maintain a focus on broader economic stability.

| Interest Rates (BoE) | Control inflation | Hinders green investment |
| Fiscal Policy (Govt) | Targeted support | Requires budget allocation |
Frequently Asked Questions
- Why does climate change make insurance more expensive? Insurers rely on historical data to predict future risks. As extreme weather becomes more frequent and severe, these historical patterns no longer provide a reliable guide, forcing insurers to raise premiums or exit markets.
- What is a “protection gap”? It is a situation where the economic cost of a disaster exceeds the amount of insurance coverage available, leaving individuals and businesses financially exposed.
- How does the Iran war impact UK energy prices? Geopolitical instability in energy-producing regions causes supply volatility, which forces central banks to consider interest rate hikes, potentially slowing the transition to domestic renewable energy.
