I think the worries about the impact that the Iran war will have on the USD is overblown.

I think there are two interconnected reasons why:

First, the world doesn’t use USD as a favor to the US, they use those dollars because they are the best medium of exchange for international settlements. In the past countries have tried using hard currencies, like gold, but shipping commodities to settle payments is impractical. It always evolves into paper money that is backed by gold, and then more paper money than gold reserves. There’s really no way around fiat currency. When we look at different fiat currencies, there are few competitors to the USD. The word doesn’t trust currencies like the yuan and the rubble, because they lack stability (granted, for different reasons). The real competitors to the USD are Yen and the euro. The problem with the Euro is it isn’t a single country’s currency, so the entire eurozone would have to agree to serve as a reserve currency. Over in Japan, their currency is stable but they don’t have the gdp growth to sustain the debt that comes along with being a reserve currency.

Well, you might ask, why wouldn’t Europe or Japan want to be reserve currencies (more so than they already are)? It’s a privilege that the US enjoys, right?

That brings me to my second point: it’s hard to be a reserve currency. In order for counties to use a currency for trade, they’re need to have access to that currency. You can buy oil with yen, if you don’t have any yen. That means that whatever country is the reserve currency has to print a lot of that currency to make sure there’s enough to clear trade. Countries have two forms of currency: current currency (think cash in a checking account), and treasury bonds (think cash in a savings account). Most central banks want some sort of yield on their reserves, so they prefer to take treasury bonds over current currency. That means that the reserve country has to issue a lot of debt to meet that demand. That’s why the US has the massive debt that it does. It needs enough currency in the market to satisfy the demand for oil, and gold, and silver etc. There are few countries in the world that have the productive capacity to be able to service that much debt. Japan can’t. The eurozone can’t. So the only real competitor is hard currency, and we already covered the problems with hard currency.

Overall, the US economy would grow if we could shed debt at the federal level, and that would be the outcome of dedollarization globally. Other countries want the dollar as the world reserve currency just as much as the US wants to serve as the reserve currency. That’s how the current system came to be. Saudi Arabia didn’t decide to do the US a favor by creating the petrodollar recycling system we have today. They agreed because it’s better for them as well.

Also, as an honorable mention, the USD is seen as a safe haven asset, so people buy dollars when there is uncertainty in the world, but that’s because of its reserve status, so this is more of a sub point.
