Expensive Arab cities exist, there's no denying that. But, what if we told you some already expensive cities became just a tiny (a lot) pricier?

Well, it's the unfortunate truth. In a recently released report titled "The Worldwide Cost of Living 2019" by the Economist Intelligence Unit (EIU), several Arab cities witnessed inflation in the past 12 months, leading to a spike in the city's prices of consumer goods and services. 

Four Arab cities made it to the report's "biggest movers up in the ranking in the past 12 months." These include Casablanca, Muscat, Abu Dhabi, and Riyadh.

Most expensive cities in the world

According to the report, Singapore, Paris, and Hong Kong shared the title of the world's most expensive cities; all three ranked No.1 on the list.
