7 days late here, but its not an accident that things are priced in USD in the middle of transactions, and its not purely because the US wanted it that way. Imagine if you as an Australian wanted to trade with venezuela. You go and make a deal selling something for some bolivars. But by the time you get the money the bolivars are not the worth the same in AUD as when you started the deal. Now you might say that the Venezualans should just hold some AUD in order to trade with australia. but they want to trade with the rest of the world as well so they would have to hold some of everyones currencies based on how much they plan to trade with them. This is infeasible so instead they use USD as the middle man to trade with everyone else, and everyone else agrees that they will accept USD for their trades. this removes the currency risk between countries assuming the USD is liquid and remains somewhat steady, which it has for the purpose of world trade.
