Banks across the region are facing rising financial and operational risks as the frequency and severity of natural disasters continue to increase, prompting regulators and financial institutions to reassess their risk management frameworks. Extreme weather events such as floods, storms, droughts and heatwaves are no longer viewed as rare shocks but as recurring threats with long-term implications for asset quality and financial stability.
Climate-related disasters directly affect banks through higher credit risk, particularly in sectors such as agriculture, real estate, infrastructure and small businesses that are highly exposed to weather disruptions. Loan defaults tend to rise after major disasters as borrowers struggle with income losses, damaged assets and business interruptions. At the same time, collateral values, especially property and land, may decline in disaster-prone areas, weakening banks’ balance sheets.
Operational risks are also intensifying. Floods and storms can disrupt branch operations, data centres and payment systems, affecting service continuity. While digital banking has improved resilience, banks remain vulnerable to power outages, connectivity failures and physical damage to critical infrastructure during extreme events.
Regulators are increasingly urging banks to integrate climate and disaster risks into stress testing, credit assessment and capital planning. Financial institutions are being encouraged to use scenario analysis to assess how repeated disasters could affect portfolios over time, rather than treating such events as one-off shocks. There is also growing focus on improving data quality, including mapping loan exposure to high-risk geographic zones.
In response, banks are strengthening insurance coverage, diversifying portfolios, and enhancing business continuity planning. Some institutions are also adjusting lending policies, pricing risk more carefully in vulnerable regions, and supporting customers with disaster-resilient financing solutions.
As climate volatility intensifies, natural disasters are becoming a core strategic risk for banks rather than a peripheral concern. How effectively banks adapt their risk management practices will play a crucial role in safeguarding financial stability in the years ahead.
