The USD, in effect, does not. It's a reason I'm somewhat bearish on it. In the 70s we made a number of agreements with a variety of Mideastern nations. We gave them what seemed like the world and asked that simply require payments of oil to be transacted on the dollar, and that they invest their excess revenues into US securities. In fewer words, the petro dollar. And those agreements, for the most part, persist to this very day. A US dollar guarantees you access to oil. And so long as oil is the most in demand commodity in the world, the US dollar will remain the most in demand currency in the world - guaranteeing access to the goods and services of any country. This is why the US dollar is the world reserve currency, or the money most countries keep under their bed in case of a rainy day. However, if this changes (renewables, Saudi Arabia deciding to switch allegiance to Russia/China, etc) what happens? We've a lot of debt that's only increasing and it's unclear to me how tall the USD would stand without its crutch.
