With the invention of computers, internet and lately the social media, the communication around the world has increased and people living in different parts of the world connect closer when compared to our ancestors. Areas such as Art, food, Culture, law, and currency from different parts of world have integrated the recent years. Some people are also coming with idea of one world, one currency. Have you ever imagined our world using one currency, with one regulatory board? Well, this has passed through my mind when I was traveling to Vietnam. This also reminds me, the complication of exchanging the Indian currency to US dollars and then, into Vietnamese Dongs.
Now, keeping aside my problem, let me define what is single global currency would mean? It is, as one can see from the illustration of Euro, that different countries have a cardinal bank, common currency, a rational and adhering fiscal policy.
