IMF DATA

This dataset provides a cross-country indicator of parallel exchange rates based on crypto markets. Parallel exchange rates are measured as the price of bitcoin on the local market relative to the U.S. market. Parallel exchange rates are particularly relevant in countries with restrictions to external transactions. In these countries, agents are often willing to pay a premium to access foreign currency, reflected in a higher price of bitcoin in the local market compared to the U.S. market.
