Is the increasing frequency of extreme heat damaging the long-term productivity of your national economy?
A report titled Too Hot to Work? estimates that heat-related productivity losses have reached US$2.4 trillion in the Asia Pacific region. The study highlights significant economic risks tied to extreme temperatures, affecting major sectors like real estate and consumer staples.
Why it matters
Asia Pacific faces these immense losses due to high local temperatures and a heavy concentration of heat-sensitive economic activity. Productivity declines as heat forces shorter work hours and necessitates costlier cooling measures for workers.
MSCI found that 81 per cent of companies in the MSCI ACWI Index face heat-related revenue impacts, with a median loss of 1.25 per cent. Asia Pacific is projected to see GDP losses reach 3.5 per cent over the next 75 years under the SSP2-4.5 scenario.

The details
Heat limits output by slowing down labor productivity and forcing developers to implement mandatory work-rest practices. Real estate firms in Asia are particularly vulnerable, accounting for 20 of the 32 companies identified as high-risk with over 5 per cent of revenue at risk.

Over the next 75 years: Projected GDP loss period for the Asia Pacific region.
Seasonal Patterns
The report utilizes the SSP2-4.5 climate scenario to model future economic output relative to current environmental benchmarks. These projections indicate that heat-driven productivity hurdles may become a structural feature of the regional economy rather than an isolated anomaly.
Businesses and workers in high-risk zones like India, China, and the Philippines may face shifts in operational schedules and labor regulations due to heat stress. Stakeholders should anticipate potential long-term impacts on asset valuations, particularly in the real estate sector.
The takeaway
Extreme heat represents a significant financial risk to global supply chains, specifically impacting industries reliant on outdoor labor. Investors and firms are increasingly pressured to evaluate revenue exposure to changing environmental conditions as productivity shifts become measurable.
