Rankings by Nominal GDP
Here are the 2019 rankings by nominal GDP, shown in current U.S. dollars. These don't take into account PPP, and by this measure, the U.S. is the world's biggest economy:
- U.S.: $21.4 trillion
- EU: $15.6 trillion
- China: $14.3 trillion
- Japan: $5.1 trillion
- Germany: $3.8 trillion
- India: $2.9 trillion
- U.K: $2.8 trillion
- France: $2.7 trillion
- Italy: $2.0 trillion
- Brazil: $1.84 trillion
Instead of PPP, these calculations use the
official exchange rate. Unlike PPP, the official exchange rate doesn't account for changes in the rate over time.
Despite the
eurozone debt crisis, the EU is lurching toward greater fiscal integration as well as a monetary one. The EU is acting more and more like a unified economy all the time. Furthermore, the EU's currency, the
euro, has successfully competed with the dollar as a
global currency.
This does make the whole EU trading bloc a failure by any definition and your claim of huge trade losses make it all the more remarkable. To argue for brexit based upon economy is flawed. Do some adding up.
