It'll be fractured for a while, which isn't great. Africa will likely primarily use the yuan, Europe the euro, and a smattering of states will use the dollar.

It'll be fractured for a while, which isn't great. Africa will likely primarily use the yuan, Europe the euro, and a smattering of states will use the dollar. This sort of fracturing is bad because the cost of goods will be pretty much unpredictable. Trade routes may once again determine how something is priced. It also means goods that are cheap today may become massively expensive tomorrow. There might be some regional stability, but things like electronics that use a global market are going to be heavily disrupted.
