UAE officials reportedly warned they may be forced to use yuan or other currencies if they run low on dollars amid the Iran war

The United Arab Emirates apparently dropped a hint the dollar’s dominance isn’t assured in the global oil trade if fallout from the Iran war gets worse.

To be sure, the UAE has plenty of money, including $270 billion in foreign-exchange reserves and trillions of dollars across its sovereign wealth funds.
