Wildfire in Thailand — Green alert

Summary

Wildfires continue across multiple regions of Thailand, with Chiang Mai experiencing severe air pollution that has topped global rankings. The fires, which began on April 12, 2026, have affected at least 6,400 rai in the Sakaerat area and are generating toxic haze that is disrupting tourism in northern Thailand's key destinations.

Supply-chain impact

• Palm oil production faces potential disruption if fires spread to cultivation areas, as Thailand is a significant regional producer and the commodity is explicitly linked to this event
• Air quality deterioration in northern Thailand could impact agricultural operations and worker safety in affected regions, potentially affecting harvest schedules and crop quality
• Transportation networks may experience reduced visibility and operational constraints due to thick haze, though no specific chokepoints are directly mapped to this event

Watch points

• Fire containment progress in agricultural regions, particularly areas with palm oil cultivation
• Air quality measurements and PM2.5 levels that could trigger further operational shutdowns or worker safety protocols
• Bangkok Metropolitan Administration's implementation of the 10 stringent measures announced to tackle the wildfire and pollution crisis
