These are the world's 20 most expensive cities for expats in 2023

New York has leapfrogged Hong Kong as the world's most expensive city to live in as an expat, while skyrocketing rents saw Singapore crash into the top five, according to a new study.

Soaring inflation and rising accommodation costs were cited as reasons for New York topping ECA International's Cost of Living Rankings for 2023, while Geneva and London remained in third and fourth places.

Singapore climbed from 13th place last year to break into the top five for the first time. That move bucks a general trend among Asian cities of slipping down the rankings, partly attributed to lower rates of inflation relative to other regions.

The Southeast Asian financial hub's rise "was due largely to major increases in accommodation costs," said ECA International's Regional Director for Asia, Lee Quane. Increased demand for rental homes, partially driven by the earlier relaxation of Covid-19 restrictions compared to other key locations in the region, was not matched by corresponding increases in the supply of accommodation.

The biggest riser of the year was Istanbul, which climbed 95 spots to 108th place, on the back of an 80% surge in prices driven by President Recep Tayyip Erdogan's economic policies, according to the report.

The survey also found:

• Dubai rents rose by almost one third on an influx of Russian expatriates, pushing the city up to 12th place
• While most European cities rose in rankings, Norwegian and Swedish cities fell on weak currencies and French cities slipped on lower inflation rates compared to EU peers
• Chinese cities fell in the rankings due to the impact of a weaker currency and lower inflation rates relative to other countries
• Rankings for all US cities surged on the strong dollar and high inflation, with San Francisco breaking into the top 10

ECA International analyses the cost of consumer goods and services, factoring in rental costs in areas typically inhabited by expats, to rank 207 cities in 120 countries and territories around the world.
