New York: US President Donald Trump's net worth has flatlined at USD 3.1 billion, but he has slid down a Forbes ranking of billionaires as the magazine believes his White House stint is harming the Trump brand.
Trump's ranking dropped to number 259 on the list of Forbes's wealthiest 400 billionaires released Wednesday, down from spot number 248 in 2017.
In 2015, the year that Trump announced his then improbable run for the presidency, Forbes valued his net worth at USD 4.5 billion.
Forbes attributes his declining wealth to deeper reporting about his assets, decline in brick-and-mortar retail, slowdown in real-estate, particularly in the luxury sector, and how being president affects the brand.
While he built much of his fortune on lending his name to projects he does not always own, a Forbes investigation say the strategy is backfiring, with his name no longer synonymous with luxury but divisiveness, driving away business partners and potential apartment buyers.
Nevertheless the value of property that he does own, including his Trump Tower penthouse, his personal private jet and Mar-a-Lago estate in Florida, dubbed the Winter White House, has gained in value, Forbes believes.
Before taking office, Trump placed his business interests in a trust managed by his adult sons, Don Junior and Eric, and veteran Trump Organization executive Allen Weisselberg.
He refused multiple calls to divest fully, leading to ongoing accusations of conflict of interest.
Forbes calculated that if Trump had liquidated, paid capital gains tax on his fortune and created a blind trust to invest everything in the booming stock market, he would be would now be USD 500 million richer.
Amazon's Jeff Bezos, whose fortune jumped USD 78.5 billion in one year, tops the Forbes list this year, with a net worth of USD 160 billion.
Microsoft co-founder Bill Gates, who held the number one spot for 24 consecutive years, is ranked number two at USD 97 billion.
Forbes said the 400 on the list have a record-breaking, combined net worth of USD 2.9 trillion, up from USD 2.7 trillion in 2017.
Entrance to the exclusive club cost an all-time high of USD 2.1 billion and 204 Americans with 10-figure fortunes fell short.
