LONDON—King Charles III presides over a monarchy in
robust financial health. Behind this is a booming real-estate portfolio of bucolic farms, wholesale warehouses and prime London offices that has helped cover a royal spending spree.
No one outside the palace is exactly sure how rich the monarchy is, or of the personal wealth of its incumbent, Charles, who was crowned on Saturday. The institution’s income comes from a variety of sources, including taxpayers, profits from large tracts of land and undisclosed privately held investments.
