4) Khalifa bin Zayed Al Nahyan of President of UAE – $15 billion

Al-Nahyan is hereditary ruler of U.A.E. capital Abu Dhabi. He controls 97.8 billion barrels of oil reserve, as well as running the world’s second-largest sovereign wealth fund with assets reported to be $627 billion. His own estimated wealth is a rather modest $15 billion in comparison, although he does spend the majority of his time on his 30-acre Seychelles estate.
