The Danish capital is one of only four European cities in the top ten of the list, which was compiled by The Economist for its Worldwide Cost of Living report 2017.
Copenhagen owes its position in the top ten priciest cities to “relatively high transport and personal care costs,” says the report by the Economist Intelligence Unit.
Singapore tops the list – as it did in 2016 – with Hong Kong in second place followed by Switzerland's Zürich at number three, the only European city in the top five.
Geneva and Paris, in joint seventh place, are the other two European cities to make the list.
Japan's capital Tokyo, the world's most expensive city until 2012, returns as fourth most expensive after dropping out of the top ten completely last year.
Copenhagen shares its position of ninth with New York City, the American metropolis having dropped a couple of spots due to the weakened dollar, according to the report.
No Chinese cities were present in the top ten, also due to steady currency devaluation as well as reduction in growth.
Paris, the only EU city besides Copenhagen to make the list and the only eurozone city, “remains structurally extremely expensive to live in, with only alcohol and tobacco offering value for money compared with other European cities,” says the report.
