Following is Forbes’ ranking of the world’s richest royals:
1. $35 bln King Bhumibol Adulyadej (Thailand)
2. $23 bln Sheikh Khalifa bin Zayed al-Nahayan (United Arab Emirates)
3. $21 bln King Abdullah (Saudi Arabia)
4. $20 bln Sultan Hassanal Bolkiah (Brunei)
5. $18bln Sheikh Mohammed Bin Rashid al-Maktoum (Dubai)
6. $5 bln Prince Hans Adam II (Liechtenstein)
7. $2 bln Sheikh Hamad bin Khalifa al-Thani (Qatar)
8. $1.5 bln King Mohammed VI (Morocco)
9. $1.4 bln Prince Albert II (Monaco)
10. $1.1 bln Sultan Qaboos bin Said (Oman)
11. $1 bln Prince Karim Al Husseini (Agha Khan)
12. $650 mln Queen Elizabeth (Britain)
13. $500 mln Sheikh Sabah al-Ahmad al-Sabah (Kuwait)
14. $300 mln Queen Beatrix (Netherlands)
15. $200 mln King Mswati III (Swaziland)
While I suspect if anything the Forbes estimate is a little low, given the recent oil prices, one has to remember that HM tends to use his personal income in large part to provide such gifts as free housing and other things to the people, built the Grand Mosque out of his own pocket, plus he has a very large number of associated Omani Royals to look after too.
Note the important disclaimer:
Keep in mind that the wealth of the royals comes from inheritances or positions of power; it is often shared with extended families and often represents money controlled by them in trust for their nation or territory. For these reasons, none of the 15 royals on this list would qualify for our annual ranking of the world's billionaires, regardless of their net worth.
Because of technical and idiosyncratic oddities in the exact relationship between individual and state wealth, these estimates are perforce a blend of art and science.
