Some of the size relations between areas are kind of suprising to me. For example, the size of Spain wealth with Germany (similar), Brazil (a lot bigger) or Arabia Saudi. I suppose that this chart is about de amount of wealth of multinational companies, not the common people's savings or so. On the other hand, the color code on the world regions that encompass nations is significant.

The researchers at Credit Suisse define wealth, or “net worth,” as the sum total of all financial assets minus any debts. One can argue with the methodology, especially as it relates to the value of intangible assets geography or cultural sites. But this is similar to a balance sheet that a household or business might create, except it’s for an entire country. We grouped each one by continent, letting you quickly compare the total net worth of different countries around the world.
