Rothschild's London-based RIT Capital Partners wisely reduced its exposure to sterling and bought gold in 2016 amid political and economic uncertainty. The strategy worked. The business is now worth nearly £3bn, with its share price rising last year. He and his family trusts have a £527.2m stake. Stripping out charitable holdings and allowing £115m for other assets including art, an £18.3m stake in oil business Genel Energy and a large private wine collection at his Buckinghamshire home, Rothschild, 81, is worth £735m.
