Maybe. But that’s not how it has worked in the past. In other cases capital controls like this cause international businesses to not trade in the currency and to instead demand other currencies to settle accounts, causing more capital flight.

The western currencies dominate foreign trade for lots of reasons, but the biggest by far is that they are easy to move.
