An IMGlobalWealth.News Report
Singapore, one of the world’s foremost wealth-management centres and home to the world’s highest-ranked passport, has experienced a dramatic deterioration in air quality, reaching the top of global pollution rankings as smoke from Indonesian wildfires spreads across Southeast Asia.
According to Swiss air-quality monitoring company IQAir, Singapore became the world’s most polluted major city on 7 October, recording an Air Quality Index (AQI) of 211, classified as very unhealthy.
The city-state returned to first place on 12 October, according to Agence France-Presse (AFP), as persistent haze continued to affect the region.

The rankings reflect real-time measurements rather than annual pollution averages, with positions changing according to atmospheric conditions. SAYS

Wildfires Trigger Regional Health Emergency
Singapore’s National Environment Agency (NEA) reported a 24-hour Pollutant Standards Index (PSI) of between 118 and 155 on 12 October, within the unhealthy range.
The agency attributed the deterioration to smoke drifting from forest and peatland fires in Indonesia’s Sumatra and Kalimantan regions.
Singapore’s Ministry of Health activated its Haze Subsidy Scheme on 12 October, offering subsidised treatment for respiratory conditions, including asthma, bronchitis and chronic obstructive pulmonary disease.
Eligible residents can receive treatment costing no more than S$10, with additional subsidies available to qualifying elderly and lower-income citizens. National Environment Agency
The crisis has also affected neighbouring Malaysia, where schools have closed because of dangerous pollution levels.
Reuters reported on 13 October that Indonesian authorities had recorded 277,075 cases of respiratory illness linked to the fires across seven provinces. President Prabowo Subianto has ordered additional resources to combat the wildfires. Reuters

A Global Wealth Powerhouse Under Environmental Pressure
The environmental crisis presents a striking contrast with Singapore’s international reputation as a destination for global capital, private wealth and internationally mobile families.

According to the Monetary Authority of Singapore (MAS), the country’s asset-management industry expanded by 10.1% in 2025, reaching a record S$6.7 trillion in assets under management.
By December 2025, more than 2,000 single-family offices were benefiting from Singapore’s investment-related tax incentives, reflecting its importance as a centre for managing international family wealth. Monetary Authority of Singapore
Singapore also retains the world’s most powerful passport according to the 2026 Henley Passport Index, providing access to 192 destinations without a prior visa. Henley & Partners
Yet the latest haze episode highlights a vulnerability extending beyond Singapore’s economic achievements.
Despite its sophisticated infrastructure, financial strength and international standing, the city-state remains exposed to transboundary pollution originating hundreds of kilometres beyond its borders.
For a country that has established itself as a preferred destination for international wealth and global mobility, the crisis reveals a less visible dimension of life in one of Asia’s most successful financial centres.
