UAE set to welcome even more millionaires as wealthy individuals abandon the UK

The United Arab Emirates is on track to be the world's top wealth magnet for the third year running, according to the Henley Private Wealth Migration Report.

At the same time, the U.K. – already the source of many of the UAE's expatriates – is projected to see its millionaire population drop by 17% by 2028, according to Swiss bank UBS.

High-net worth individuals are in many cases voting with their feet, seeking greener pastures – or in the case of tax-free expat hubs like Dubai, sandier beaches – as costs and taxes rise in their home country. The trend is likely to accelerate in the wake of the landslide election victory for the U.K.'s Labour Party in June, according to some financiers.

"There are push and pull factors for this trend of millionaires opting to relocate to Dubai," Karim Jetha, a longtime regional investor who relocated to the UAE from the U.K. during the pandemic, told CNBC.

"Push factors include the prospect of higher taxes under a new Labour government. For example, one of Labour's campaign pledges was to levy VAT on private school tuition, which would raise the cost by 20%," he said. "Pull factors include Dubai's perception of being extremely safe and visa reforms that encourage migration."

The UAE is set to see a record net inflow of 6,700 millionaires from around the world by the end of 2024, according to the Henley report, which was released in June. That's nearly double the second-ranked country on the list, the U.S., which is expected to welcome a net inflow of 3,800 millionaires in the same time frame. 

"With its zero income tax, golden visas, luxury lifestyle, and strategic location, the UAE has entrenched itself as the world's number one destination for migrating millionaires," the report said. The
