Frictionless Global Trade Boosts Prosperity
- A single worldwide currency could eliminate foreign exchange frictions and greatly simplify global trade and travel.
- Removing currency barriers would boost specialization, cross-border talent flow, and overall global productivity.

- Europe adopted the euro and removed exchange risk between member states, enabling integrated supply chains across countries.
- This allowed Germans to use Italian engines and assemble cars in Spain almost as if operating within one country.

- Sharing a currency removes independent monetary policy, linking creditor and debtor nations to the same fate.
- This can force fiscally disciplined countries to shoulder risks from weaker members, as seen with Germany and Greece.
