Insurance market cycles are familiar to brokers, but they are far less visible to clients. For businesses and property owners, insurance pricing can feel unpredictable or hard to justify, particularly when premiums rise despite no change in their own claim history. Understanding the forces behind market cycles can help brokers explain why insurer appetites move the way they do.
Central to these movements is capital: where it comes from, how it is deployed and how quickly it can retreat when risk or returns change. Insurance capital represents the financial resources of insurers and reinsurers to underwrite risk and pay claims. Regulators require insurers to hold capital relative to the risks they carry, which means capital availability directly affects the amount of insurance capacity that can be deployed into any market.
For brokers, this matters because capital flows directly influence underwriting appetite. When insurers are well capitalised and risk-adjusted returns are attractive, capacity expands and competition increases. When losses mount, returns deteriorate or uncertainty rises, capital becomes constrained, underwriting tightens, and insurers become more selective about the risks they are prepared to take on and at what price.
This helps brokers explain why a client may be facing a premium increase despite not making a claim. The answer is that insurance pricing is shaped by the client’s risk profile and wider market forces. Major weather events, claims inflation, reinsurance costs, regulatory pressure and global capital flows all influence insurer behaviour. A client may be well managed and claims-free but still exposed to a market where the cost and availability of capital have changed.
Reinsurers spread risk internationally, absorbing large or volatile exposures that individual insurers cannot retain alone. This helps insurers manage volatility and continue supporting clients through challenging periods. Over the past two decades, alternative capital, including catastrophe bonds, collateralised reinsurance and sidecars, has added further depth to global capacity, particularly following large loss events.
These capital dynamics underpin the insurance market cycle. Hard markets typically follow periods of capital depletion, when losses and uncertainty drive price increases and tighter terms. Those improved returns then attract new capital, increasing competition and capacity. Over time, softer conditions emerge, before declining returns or new losses trigger the cycle once again.
We are currently seeing evidence of this cycle playing out in New Zealand. Following the significant weather events of 2023, insurers rebuilt capital through premium increases, disciplined underwriting. Reinsurance costs stabilised and there was a more benign claims environment. As a result, insurer confidence has improved, and new capacity has entered the market increasing competition across several major classes.
For brokers, the current environment creates both opportunity and responsibility. Softer conditions should not be treated only as a chance to achieve lower premiums. They also provide an opportunity to revisit coverage quality, challenge restrictions introduced during harder market conditions, and strengthen clients’ long-term risk positions.
While conditions are currently easing, New Zealand remains exposed to volatility. One major catastrophe event could quickly change insurer confidence and push the market back towards tighter conditions.
For clients, that means insurance decisions made in a softer market should not assume today’s conditions will last. For brokers, it reinforces the need to use current market conditions to improve cover where possible and help clients understand why insurance availability is shaped by forces well beyond their own claim history.
