Number of millionaires to soar globally but plunge in the UK, research finds

LONDON — The number of global millionaires is set to keep rising over the next five years — with the U.K. a stark outlier, according to the 2024 Global Wealth Report from UBS.

The number of adults owning $1 million or more is expected to grow in 52 out of 56 developed and developing economies surveyed between 2023 and 2028. Gains will be led by tech powerhouse Taiwan, where the number of millionaires is set to jump 47% on the back of the booming microchip industry and a rise in immigration by wealthy foreigners.

That growth was followed by Turkey (43%), Kazakhstan (37%), Indonesia (32%) and Japan (28%). The two hubs in which the most global millionaires are based, the U.S. and mainland China, are set to see their figures rise 16% and 8%, respectively.

However, the number of millionaires is forecast to plunge by 17% in the U.K.

Paul Donovan, chief economist at UBS Global Wealth Management, said that the U.K. currently has the third-highest number of dollar millionaires in the world, which he called "far more ... than it deserves to have as an economy."

He added that countries such as France and Italy, where the number of millionaires is set to rise 16% and 9%, respectively, are seeing a more "natural" growth, while any U.K. growth would be offset by capital outflows due to various "push and pull" factors.

That is partly due to natural shifts in wealth distribution as the global economy goes through structural changes and capital moves around the world, he said on a media briefing.

Other factors set to drive the decline in millionaires include the U.K.'s introduction of sanctions against Russia — with wealthy Russians having long used London as a home for their assets — and the "non-indigenous millionaire population" constantly
