The 10 most expensive cities in the world

• The Economist Intelligence Unit highlighted the most expensive places among 173 cities.
• Zurich surged a few spots in the ranking to tie with Singapore at No. 1, the new report said.
• Geneva, Paris, and San Francisco were among the 10 most expensive cities.

It's expensive to be in Singapore, in part because of clothing and transport costs. Zurich is also expensive, partly from high grocery prices. The two places tied at No. 1 in a ranking of how expensive 173 cities around the world are.
