World's richest royal family worth more than Elon Musk and Bill Gates combined

The British royal family has an estimated net worth of £69 billion ($88 billion) but this pales in comparison to the wealthiest royal family in the world

The British Royal family's wealth is estimated to be around £69 billion ($88 billion), as per Forbes. Their wealth stems from tangible assets such as properties, as well as the value of the family brand.

The Duchy of Cornwall and the Duchy of Lancaster estate, which includes land, property and other assets that belong directly to the Sovereign, are among the valuable assets within the Royal Family. The prestigious Savoy Hotel and Somerset House are part of the Duchy of Lancaster estate, with net assets totalling approximately £652.8 million ($755.4m).

King Charles' personal fortune is estimated at about £559.6 million ($772 million), making him the 258th wealthiest person in the UK. However, one Royal family far outstrips most others with a net worth four times greater than Elon Musk and Bill Gates combined.

The world's richest Royal family is the House of Saud, the ruling Royal family of Saudi Arabia, with a staggering net worth of £1.1 trillion ($1.4 trillion). In comparison, the world's richest man, Elon Musk, has a net worth of £264.8 billion ($304 billion), while Microsoft mogul turned philanthropist, Bill Gates, has a net worth of £81.5 billion ($105 billion).

The House of Saud's net worth is so vast that it is estimated to be roughly 16 times that of King Charles's family, reports the Express.

The Saudi Arabian Royal family's eye-popping wealth, largely derived from vast oil reserves, affords them a life of luxury that includes grand palaces, private jets, extravagant yachts and a highly lucrative art collection. This immense wealth among Middle Eastern Royal families has been a common feature in many regions, despite monarchies having previously held limited authority under the Ottoman Empire.

However, following its collapse after World War I, these monarchies have seen their power and wealth skyrocket. The majority of this wealth is due to the exploitation of valuable resources found within the region, with Gulf monarchies in particular continuing to prosper.

Consequently, Royal families from the United Arab Emirates (UAE), Oman, Bahrain, Qatar, Kuwait and Saudi Arabia are living a dream-like life. The Saudi Royal family alone consists of around 15,000 members, with the lion's share of wealth being held by approximately 2000 relatives.

King Salman bin Abdulaziz Al Saud, who has been at the helm since his reign began in 2015, currently heads the family. His most famous son and apparent heir, Mohammed bin Salman, also known as MBS, is also the current Prime Minister of Saudi Arabia and is widely regarded as the country's de facto ruler.

The Royal Saudis, with their immense wealth, have made a number of extravagant purchases over the years. These include properties scattered around the globe like France's Chateau Louis XIV, bought by MBS for a whopping £235 million, and other lavish acquisitions such as Leonardo da Vinci's Salvator Mundi painting for £349.6 million and a staggering £392 million yacht - mere pocket change for such affluence.
