They’re both enormously wealthy, but King Charles III is going to be appointing as prime minister someone wealthier than him in Rishi Sunak.

Sunak is a former Goldman Sachs GS, +1.40% analyst and hedge-fund manager, but his wealth overwhelmingly comes from his wife, Akshata Murthy, who is the daughter of the Infosys founder N.R. Narayana Murthy.

Her 0.93% stake in Infosys 500209, +1.15% INFY, +0.61%, at Friday’s closing price, was worth $710 million.

Together, they own four properties — including one in Santa Monica, Calif. She also owns Catamaran Ventures, a venture-capital firm whose net book value at the end of last year was £3.5 million ($4 million).

The king’s assets are less easily marked to market. Forbes puts his personal assets at around $500 million, and other reports say his personal worth is more like $600 million.

The queen consort, Camilla, is worth a few million, as well, and has her own country house.

Charles, on the other hand, does oversee some $42 billion in the monarchy’s assets, according to Forbes, which is his to use but not sell.

He can’t personally profit from a hypothetical sale-and-leaseback of, say, Buckingham Palace.
