I don’t think that makes a lot of economic sense from a theory perspective and I’m saying this as someone with a background in the subject. Was just curious to know your logic.
When the currency will depreciate; imports will automatically go down especially of the needless luxury goods which we import way too much of. And assuming exports remain at similar level; then more of that will be used for importing fuel.
