Most Expensive Cities in the World – Mercer’s 2024 Rankings
Hong Kong retains its position as the most expensive city globally for expatriates in 2024, with Singapore and three Swiss cities rounding out the top five. These rankings reflect persistent pressures in housing markets, currency stability, and inflation rates affecting international assignees across 226 locations worldwide.
The annual Mercer Cost of Living Ranking places Zurich third, Geneva fourth, and Basel fifth, while Western Europe and North America dominate the upper echelons of the list. London surged nine positions to eighth place, reflecting acute financial sector demand, whereas New York slipped one spot to seventh despite remaining the baseline index city.
Switzerland now holds four entries within the top ten, joined by Nassau in the Bahamas and Los Angeles in California. All United States cities rank within the top 100, underscoring the broader cost pressures facing North American expatriates compared to global counterparts.

How Are Cost of Living Rankings Calculated?
Mercer’s methodology specifically targets expatriates relocating with employer support, utilizing New York City as the baseline index of 100. The survey encompasses over 200 expense categories across 226 cities, with housing representing the largest weighted component followed by transportation, food, clothing, household goods, entertainment, and personal care.
Expatriate Focus vs. General Consumer Indexes
Unlike the Economist Intelligence Unit’s Worldwide Cost of Living survey, which emphasizes broader consumer prices, or Numbeo’s crowd-sourced index, Mercer tailors its data to international assignees. This distinction produces divergent results: Numbeo’s 2026 early data places Hamilton, Bermuda at the top for general consumers, with San Francisco tenth, whereas Mercer prioritizes relocation packages and expatriate housing allowances.
The Mercer index weights imported goods and premium accommodation heavily, meaning a city’s ranking may not reflect local resident expenses or domestic purchasing power. Currency fluctuations against the US dollar directly affect these calculations annually.
Data Collection Standards
Conducted annually since 1998, the survey adjusts for local taxes and exchange rate movements at specific measurement dates. Human resources departments utilize these figures to structure compensation packages for cross-border assignments, making the data critical for corporate mobility planning rather than general tourism budgeting.
What Factors Drive High Costs in These Cities?
Property markets represent the primary driver of high placement in the 2024 rankings. Housing scarcity in Hong Kong and Singapore combines with demand for luxury accommodations suitable for international executives, pushing accommodation costs well above the New York baseline.
Swiss Economic Stability
Zurich, Geneva, Basel, and Bern benefit from strong local currencies and robust economic fundamentals. The Swiss franc’s stability against major currencies, combined with high local wages and standardized premium pricing for goods, maintains these cities in the upper rankings regardless of global inflationary pressures affecting other regions.
Limited land availability in island nations and financial centers creates structural scarcity. Expatriates in Hong Kong and Singapore typically face accommodation budgets exceeding those in comparable European cities by significant margins.
Inflation and Exchange Rate Impacts
Western cities generally grew costlier in 2024 amid persistent inflation, while certain Eastern locations saw relative decreases in expatriate costs due to currency depreciation. The US dollar’s strength kept American cities elevated in the rankings, with all US locations maintaining positions within the top 100 globally.
What Are Typical Costs for Expats?
Expatriate cost structures vary significantly by region. While Mercer does not publish absolute dollar figures for specific cities, the index reveals that assignments in Swiss and Asian financial centers require substantially higher housing allowances than those in Eastern Europe or South America.
Regional Variations
Dubai ranks fifteenth in the Middle East, offering a different cost profile centered on luxury goods and private education rather than pure housing density. In Africa, Bangui ranks fourteenth, reflecting import logistics and security-related premiums for expatriate housing. These regional leaders demonstrate that high costs stem from distinct local factors rather than uniform global inflation.
Currency Considerations
International assignees must account for exchange rate volatility when evaluating packages. Compensation structures tied to North American financial benchmarks, such as those referencing the Prime Interest Rate Canada, affect purchasing power for those relocating from or to Commonwealth banking systems. Conversion examples like 325 USD to CAD illustrate how currency movements between major economies directly impact real-world expatriate budgets beyond the static index rankings.
Annual ranking snapshots capture currency values at specific dates. Assignees negotiating multi-year contracts should build adjustment clauses into contracts, as shifts in the US dollar, Swiss franc, or Singapore dollar can alter effective purchasing power within months.

Why Do Cost of Living Rankings Matter?
Multinational corporations rely on these indexes to structure equitable compensation packages for international assignments. When an organization relocates talent from Toronto to Zurich or from London to Singapore, the housing indices and currency adjustments determine hardship allowances and salary modifications necessary to maintain consistent standards of living.
Human resources departments utilize the data to forecast mobility budgets, while individual expatriates reference the rankings to negotiate relocation packages. The distinction between expatriate-focused and general consumer indexes proves critical: a city affordable for local residents may require substantial premiums for international assignees requiring specific housing standards, schooling, and imported goods.
What Sources Inform These Rankings?
Mercer’s annual survey represents the primary source for 2024 rankings, covering 226 cities with data collected specifically for international assignees. The methodology, established in 1998, compares expenses against New York City as a baseline, adjusting for currency fluctuations and local taxation policies.
Housing costs represent the largest weighted factor in the index, followed by transportation, food, clothing, household goods, entertainment, and personal care, with all figures adjusted for currency fluctuations and local taxes relevant to expatriate employees.
Mercer Cost of Living Methodology, 2024
Secondary verification comes from the Economist Intelligence Unit and Numbeo, though these employ different methodologies. Mercer’s official mobility insights provide the definitive source for employer-sponsored relocation cost calculations, while Numbeo offers crowd-sourced general consumer perspectives that often diverge from expatriate-specific realities.
Key Takeaways on Global Cost of Living
Hong Kong and Singapore define the upper limit of expatriate costs in 2024, while Swiss cities maintain four positions within the top ten through currency strength and economic stability. London’s nine-position surge reflects acute financial sector pressures, contrasting with dramatic falls in Lagos and rises in Accra across emerging markets. Organizations planning international assignments should consult current financial benchmarks and currency conversion tools to contextualize static rankings against real-time economic conditions.
