There is a lot of money available to be invested in each country, but the amount of available capital varies widely from country to country. In general, the wealthier a country is, the more available capital there is to invest. However, there are exceptions to this rule. For example, some very wealthy countries may have relatively little available capital because they have a large amount of money tied up in other investments, such as real estate or art. The following is a list of countries ranked by their available capital, from highest to lowest: 1. United States: $21.4 trillion 2. China: $15.3 trillion
