These are the world's most expensive cities in 2021

(CNN) — All over the world, it's been a tough year on wallets.

Supply-chain blockages and changing consumer demand have pushed up the cost of living in many of our biggest cities, according to new research published Wednesday, and inflation is the fastest recorded over the past five years.

One city has been experiencing more rapid change than most, jumping from fifth place to first in this year's Worldwide Cost of Living index released by the Economist Intelligence Unit (EIU).

The Israeli city of Tel Aviv topped the rankings for the first time, overtaking last year's leader Paris, which is now tied in second place with Singapore.

The EIU attributes Tel Aviv's sharp rise on the index to increases to grocery and transport prices and the strength of the Israeli shekel against the US dollar.

Everyday goods and services

The 2021 Worldwide Cost of Living index tracks the cost of living across 173 global cities -- 40 more than last year -- and compares the price of more than 200 everyday products and services.

Data for the survey, which has been carried out for more than three decades, is gathered by EIU's global team of researchers each March and September.

The index is benchmarked against prices in New York City, hence cities with currencies that are stronger against the US dollar are likely to appear higher in the rankings.

Zurich and Hong Kong are at Nos. four and five respectively, having held the top spot last year alongside Paris. New York, Geneva, Copenhagen, Los Angeles and Osaka round up the rest of the top 10.

The upper rankings rankings continues to be dominated by European and developed Asian cities. The lowest-ranking cities are mainly in the Middle East, Africa and less wealthy parts of Asia.
