This month, the International Air Transport Association released the 2023 Henley Passport Index, which reveals the world’s most powerful passports.

The Henley Passport Index measures visa-free access to 227 destinations across the world. It ranks the world’s passports according to the number of destinations their holders can access without a prior visa.

A key finding from the index is what they call the “direct link between passport strength and access to the global economy.”

For example, the Japanese passport gives visa-free access to 193 destinations, which accounts for a whopping 98% of the global economy. On the other end, citizens of the index’s lowest-ranking countries such as Afghanistan, Iraq (visa-free score of 29), and Syria (visa-free score of 30) are effectively shut out of various opportunities for economic mobility and growth.
