For senior leaders in the insurance sector, inflation is more than a temporary nuisance. It’s a persistent structural challenge that’s reshaping capital adequacy, reserving assumptions and investment returns. While inflation may be moderating (currently the UK’s annual inflation rate is 3.8% [as of October 2025], down from a 41-year high of 11.1% in October 2022), its consequences are still felt in claims costs, policyholder behaviour and asset valuations and the structural pressures behind it – tight labour markets, supply chain fragility and sustained fiscal spending – remain.
Inflation is a long-term factor that needs to be built into every financial model and strategic decision. For CFOs and CROs in the insurance sector, this environment demands more than reactive cost control. It calls for a proactive rethink of capital models, reserving practices and investment strategies, so that portfolios are built to withstand and even benefit from the next phase of economic uncertainty.
Inflation affects insurers on multiple fronts. On the liabilities side, claims become more expensive as the cost of, for example, car parts, building materials and other goods rise. Legal fees and service costs also increase, often faster than general inflation. On the asset side, higher interest rates can improve returns on new investments. Still, they also reduce the value of existing bonds and make it harder to match assets and liabilities.
In the UK, this pressure has been particularly intense. The combination of higher-than-expected CPI, volatile gilt yields, and sector-specific cost increases (particularly in cars and property) has created a challenging environment for insurers seeking to maintain solvency and competitive pricing.
The key for CFOs and CROs is to look beyond short-term volatility and build a framework that is flexible, data-driven and inflation-resilient.
Traditional capital models were never designed for today’s inflation scenarios. They often rely on historical correlations that underestimate how long inflationary pressures can linger.
CROs and CFOs can take a more resilient approach by:
Stress-testing under multiple scenarios – rather than model a single inflation outlook, run moderate, prolonged and high-volatility scenarios that capture both macro and insurance-specific effects. Reverse stress testing can reveal vulnerabilities that were previously not visible
Dynamic solvency monitoring – move from annual reviews to real-time dashboards that track how inflation is influencing solvency and liquidity positions
Refresh risk appetite statements – inflation-adjusted capital thresholds ensure that decisions such as dividend payments or reinsurance strategies stay aligned with current realities.
This approach shifts capital modelling from compliance to strategy. It’s not about being over-cautious or adding complexity; it’s about giving the business the flexibility it needs when market conditions move faster than expected.
Reserving is where the impact of inflation can be felt most acutely and can erode financial strength. Underestimating claims inflation today can lead to reserve strengthening, impacting earnings and regulatory capital. Improving accuracy requires a combination of actuarial discipline and economic awareness.
Best practices include:
Blending actuarial and macroeconomic insight – actuarial models should draw directly from real-time economic data, including wage indices, materials inflation and construction costs
Tracking inflation by segment – claims inflation behaves differently across business lines. Segment-specific inflation indices, such as Producer Price Inflation, can improve reserve accuracy and prevent generalised assumptions from masking real risk
Reviewing assumptions frequently – in fast-changing markets, annual reviews are no longer enough. Quarterly assumption reviews, particularly in volatile markets, allow for quicker recalibration if inflation expectations move suddenly
Being transparent with regulators – clear communication of inflation-linked reserving assumptions will strengthen credibility with the PRA and external stakeholders.
Ultimately, the aim is not to predict inflation perfectly, but to stay close enough to the data to make surprises manageable, not destabilising.
Inflation often complicates an investment strategy by reducing real returns and increasing volatility, but it also opens up new opportunities for diversification and stronger yields – if it’s managed with precision. The challenge is to capture yield without taking on disproportionate risk.
This could mean:
Rebalancing towards inflation-sensitive assets – infrastructure, property and inflation-linked gilts can help to balance inflation exposure while maintaining capital efficiency
Dynamic duration management – shorter-duration portfolios can offer flexibility as rates move and can reduce volatility in both solvency and earnings
Rethinking credit risk – inflation often triggers monetary tightening which increases credit spreads, heightening risk. But, it can also create opportunity, so regular stress-testing is vital
Taking a tactical approach – inflation-driven rate moves can create liquidity strain, so tactical allocation and active management can help to protect returns without undermining yield.
The best-performing portfolios will be those that can adapt quickly as inflation and interest rate expectations evolve.
Embedding inflation awareness into governance and decision-making
Managing inflation isn’t simply a technical exercise; it requires embedding inflation awareness across governance, reporting and risk culture to ensure a consistent response.
Cross-functional committees – some insurers are bringing together dedicated working groups that include actuarial, finance and investment teams, to offer a variety of perspectives on inflation trends and to coordinate strategy. This gives CFOs and CROs a distilled view of how inflation affects the balance sheet.
Integrated reporting – regular inflation impact reports which cover capital, reserves and investments, enable boards to make informed strategic decisions.
Policyholder communication – transparent communication about pricing adjustments and policy terms builds trust and manages reputational risk in a competitive market.
Governance structures that integrate inflation awareness in communications make it easier to act decisively when economic conditions change.
Despite forecasts that inflation will remain above 3%, well into 2026, no one can full predict how it will behave over the next few years. However, insurers can control how ready they are for any changes. The firms that flourish in the future will be those that treat inflation not as a passing phase but as a permanent variable in their financial strategy.
For CFOs and CROs, inflation-proofing means building agility into every layer of their financial model, from capital planning and reserving to asset allocation and governance.
By aligning actuarial, financial and investment assumptions with the reality of inflation, insurance leaders can safeguard profitability and capital strength, while positioning their portfolios for long-term stability.
