The currency composition of foreign exchange reserves: A new database

In this paper, I present what is, to the best of my knowledge, the most comprehensive and detailed database on the currency composition of countries’ foreign exchange reserves, constructed entirely from publicly available sources. Covering the period from the introduction of the euro in 1999 to 2026, the database provides information on the reserve currency composition of 149 countries across 23 currencies.



The Working Papers of Danmarks Nationalbank describe research and development, often still ongoing, as a contribution to the professional debate. The viewpoints and conclusions stated are the responsibility of the individual contributors, and do not necessarily reflect the views of Danmarks Nationalbank.
