Can a stock index be measured in different currencies?
Content: If we look in to Euro, we saw how Germany benefited with this. Germany was already dominant in the exports and the common currency made its products more competitive especially within Europe. More countries started buying more German products and this boosted their exports and GDP. Likewise, developing countries may also benefit with a single currency. Countries which suffer from hyperinflation may find a higher valued currency a relief. Cons
Well, the most obvious con of a single currency would be the need for a global single organization or body to regulate, manage, print and decide how much to print. Countries will no longer have independent monetary policies. Countries will not be able to control interest rates to stimulate economic growth. Rather, any change in a monetary policy will effect globally, having different effects on different countries. Having a same currency will imply problems related to having a global government.
