Climate risk puts new pressure on Asia-Pacific insurers

Climate change is projected to put greater pressure on insurers and businesses across Asia-Pacific amid rising temperatures, downpours and the like, which spawn more complex and interconnected risks.
Tokyo offers a glimpse of what may lie ahead. According to a physical climate risk assessment of Ueno Park by HDI Risk Consulting (HRC), a wholly owned subsidiary of HDI Global, extreme heat and heavy rainfall lead to consequences extending beyond individual properties, affecting tourism, infrastructure, supply chains and business continuity.
The study found that, under a business-as-usual scenario, heatwaves in Tokyo could last around 21.28 days annually by 2050, compared with 6.94 days in 1970. Meanwhile, sudden torrential “guerrilla rainstorms” can place pressure on urban drainage systems, potentially disrupting transport, supply chains and businesses.
With this, HDI Risk Consulting Team Lead for Natural Hazards and Climate Risks Analysis Wiebke Cundill and HDI Global Japan Managing Director and Legal Representative Hiro Yamasaki said looking beyond historical loss data is now vital for insurers when assessing commercial property risks.
“In a complex urban environment like Tokyo, climate change is fundamentally changing how commercial property insurance is assessed, underwritten, and priced,” they said.
Rather than relying only on historical loss data, insurers are increasingly considering forward-looking information on flood exposure, heat stress, and rainfall frequency as well as intensity alongside traditional underwriting criteria.
“Together, these provide a more comprehensive understanding of a property’s risk profile, helping insurers to make more informed decisions,” they said.
This shift towards more granular, forward-looking analysis, the executives said, is becoming increasingly important across Asia Pacific, where densely populated cities and highly interconnected economies can amplify the impact of physical climate events.
Resilience becomes part of the insurance conversation
While climate exposure is becoming more important in underwriting, Ms Cundill and Mr Yamasaki stressed that exposure alone does not determine the outcome for a business.
“Importantly, climate-related exposure does not determine outcomes on its own,” they said. “What matters is the individual risk profile, the quality of risk information and the resilience measures in place.”
Because of this, there should be greater emphasis on prevention and adaptation. Businesses that understand their exposures and invest in resilience could be better positioned to secure sustainable insurance solutions as climate risks evolve.
“Our role as insurers is not only to transfer risk, but also to help clients better understand and manage it,” they said. “As climate risks continue to grow, insurers need to look beyond their traditional role of paying claims after an event, and move towards helping clients anticipate risks, strengthen resilience, and prevent losses before they occur.”
That approach also requires insurers to assess how individual climate hazards can affect and trigger wider disruption.
“Rather than being determined by industry alone, climate risk exposure increasingly depends on where a business operates, how its facilities are configured, and how reliant it is on interconnected supply chains, distribution networks, and critical infrastructure,” they said.
Collaboration and better data
The executives added that maintaining accessible and sustainable insurance coverage as climate risks intensify will ultimately require closer collaboration between insurers, businesses and public authorities.
“Building climate resilience is a shared responsibility, and no single stakeholder can address their challenges alone,” Ms Cundill and Mr Yamasaki said.
Technology and climate analytics will also play a growing role in this process. HDI Risk Consulting provides clients with climate risk services including Climate Risk Screening, Climate Risk Reporting and Climate Consulting, alongside the HDI ARGOS 4.0 platform, which supports the assessment of site-specific exposures under different climate scenarios.
“At HDI Global, we believe better data leads to better underwriting decisions,” they said. By combining advanced climate analytics with local underwriting expertise, insurers can “differentiate risks more effectively” and have more meaningful discussions with clients about mitigation and business resilience.
Looking ahead, the challenge for Asia-Pacific’s insurance market will be to translate increasingly sophisticated climate data into practical action. The experience of Ueno Park demonstrates that climate risk is no longer simply a question of protecting individual assets from individual events. It is increasingly about understanding how heat, flooding and other hazards interact with the wider urban and economic systems on which businesses depend.
