Thailand’s largest listed companies are on track to absorb **almost USD 11 billion
per year** in climate‑related physical risk costs by the 2050s if no adaptation 
measures are taken, according to new analysis from **S&P Global Sustainable1**. 
The study evaluates 84 companies representing **97% of the SET100 market capitalization**
and applies high‑resolution climate‑risk modelling to quantify future financial 
exposure.

The projected annual impact—**USD 10.9 billion**—marks a steep rise from **USD 6.9
billion in the 2030s** and **USD 5.0 billion in the 2020s**, underscoring the accelerating
cost of extreme weather and long‑term climate stressors.

### **Extreme Heat and Water Stress Lead Corporate Risk Exposure**

S&P Global identifies **extreme heat, water stress, drought and pluvial flooding**
as the most material physical hazards for Thai corporates. These risks are expected
to intensify under the medium‑range climate scenario (SSP2‑4.5), affecting operations,
supply chains and asset values across multiple sectors.

### Southern Thailand: High Flood Exposure for Households and Businesses

The report highlights southern Thailand as a critical hotspot: **17% of single‑family
homes** in the region could be affected by a **100‑year fluvial flood event** by
the 2050s. Fluvial flooding already occurs **almost annually**, and the November
2025 disaster—impacting **2.8 million people across nine provinces**—illustrates
the scale of disruption businesses may face.

A dedicated case study in the report uses **high‑resolution flood‑depth data** to
assess how varying flood levels could affect residential properties and, by extension,
local economic resilience.

### Most SET100 Companies Have Adaptation Plans—But Gaps Remain

Despite the rising risks, **65% of SET100 companies** have already developed climate‑
adaptation plans, according to S&P Global’s Corporate Sustainability Assessment.
These measures could help mitigate future losses, though the report stresses that
adaptation must accelerate to match the pace of climate impacts.

### A Growing Imperative for Thai Corporate Strategy

With climate‑related physical risks set to escalate sharply over the next three 
decades, S&P Global’s findings reinforce the need for Thai corporates to integrate
climate resilience into long‑term planning, capital allocation and infrastructure
investment. The analysis leverages the **Climanomics platform**, a bottom‑up methodology
designed to quantify financial impacts from climate hazards.
