A cheap coin is usually good for business that export products or commodities. IIRC fuels, beverages, tobacco products, and materials were the major categories. But other than the US, the major importers were EU nations.
But again, IIRC UK imports were almost double the exports.
As has been the case for at least several hundred years the UK relies on imports for its very existence.
A lower pound would make all imports more expensive even ignoring tariff issues. It will make exports more attractive even ignoring tariff issues.
Can the UK increase exports and also reduce the demand for imports to at least keep the economy relatively stable?
If so, how?
