Severe flooding across southern Thailand in recent weeks has resulted in widespread destruction, with economic losses estimated at over THB500 billion ($14 billion), as per the Ministry of Finance. Recurrent natural disaster events have kept catastrophe risk firmly in focus and are expected to support sustained property premium growth in the country over the next five years, according to GlobalData, a leading data and analytics company.

According to GlobalData’s Global Insurance Database, the property insurance line is forecast to grow at a CAGR of 5.2% over 2026–30, increasing from THB59.4 billion ($1.7 billion) in 2026 to THB72.8 billion ($2 billion) in 2030, in terms of gross written premiums (GWP).

Manogna Vangari, Insurance Analyst at GlobalData, comments: “Rising disaster risks—including floods and earthquakes—are driving up insurance and reinsurance costs and excess‑of‑loss premiums, pressuring profitability and prompting insurers to bolster catastrophe protections. However, the Thai property insurance market remains resilient and is expected to expand steadily. It is forecast to remain profitable, with the average loss ratio projected to remain well below 35% during the 2026–30 period.”

The recent floods, layered atop the devastating magnitude-7.7 earthquake on March 28, 2025, epicentered in Sagaing, Myanmar, with effects felt in Bangkok, have exposed a significant underestimation of catastrophe risk in Thailand’s insurance models. Moreover, the collapse of a major construction project (Chatuchak skyscraper) and a spike in insured losses—possibly up to THB50 billion ($1.4 billion) as per the Thailand General Insurance Association—underline gaps in structural resilience, construction regulation compliance, and policy coverage limits.

In one hard-hit province, Songkhla, insurers received more than 500 property damage claims within days of the severe flooding disaster caused in mid-November 2025, as per the Office of the Insurance Commission (OIC). Across the flooded southern region, industry officials expect the number of claims to rise into the thousands as damage assessments continue.

The protection gap is increasingly visible. Many property policies either lack flood coverage or include sub-limits and exclusions that limit payout in major flood events. The OIC’s new (2026–30) Insurance Development Plan emphasizes strengthening risk management, underwriting standards for natural hazard risks, promoting digital claims processing, and narrowing protection gaps.

The impact of natural disasters is likely to push actual property claims higher than earlier projections. To address the risks more proactively, insurers are introducing multi-hazard property and condo coverages—fire, storms, floods, earthquakes, theft—with more flexible terms for households and small and medium enterprises; offering modular, embedded insurance and micro-premiums to match recurring flood seasons; and accelerating digital transformation through AI, IoT, and big-data in underwriting and claims to enhance speed and cost efficiency.

Vangari concludes: “The Thai property insurance line is expected to witness an increase in premiums, bolster catastrophe capacity, and launch products targeting flood and multi-hazard risks. Reinsurance costs and excess-of-loss pricing will sustain market hardening, while infrastructure and data centers offer medium-term premium growth. Though near-term expansion is constrained by economic headwinds, insurers’ use of digital claims, AI underwriting, and embedded distribution should refine pricing, speed claims, and improve resilience to flooding and natural disasters.”
