These Are the World’s Most Expensive Cities by Jonathan Chew @FortuneMagazine March 11, 2016, 8:17 AM EDT E-mail Tweet Facebook Linkedin Share icons Of the world’s most expensive cities, Singapore has kept its title for the third year running. The Asian island city has beat out Zurich and Hong Kong to top the latest rankings by the Economist Intelligence Unit, which surveys 400 individual prices across 160 products and services, and then compares all places with the base city of New York. The big news does involve the Big Apple: At No. 7, New York is in its highest position since 2002, and has risen 42 places up the cost of living rankings since 2011. The city’s rise has been pegged to a stronger dollar and localized inflation. Both of those factors have also pulled Los Angeles higher up the list. Currency fluctuations and weakening commodity prices have moved other cities around the rankings. Paris and Oslo have dropped on a weakening euro, and the impact of exchange-rate movement is set to impact countries like Argentina, Japan, Australia, Canada, and Russia this year, the report notes. “In nearly 17 years of working on this survey I can’t recall a year as volatile as 2015,” Jon Copestake, an editor of the survey, told the BBC. “Falling commodity prices have created deflationary pressures in some countries, but in others currency weakness caused by these falls has led to spiraling inflation.” One data point that’s missing from this ranking, as pointed out by the Wall Street Journal, is the cost of shelter (although rental costs are factored here). That could be a reason why San Francisco—recently named the most expensive city in the U.S. for singles—is not higher on this list.
