The Dataset of the Currency Composition of Foreign Exchange Reserves

Just introduced (Sept. 2021)
Ito and McCauley (2020) introduce a new dataset on the currency composition of foreign exchange reserves. The aggregated data of the currency composition of international reserves is available only for the entire world, the group of advanced economies, and that of emerging economies from the International Monetary Fund’s (IMF) currency composition of official foreign exchange reserves (COFER). However, such data are not publicly available for individual countries. They overcome the data constraint by collecting the data from central banks’ annual reports, financial statements, and other publicly available information sources and construct the dataset of the currency composition of international reserves for 75 economies in the 1999-2020 period.
The data for Latin American countries are not included due to nondisclosure agreements.

This dataset allows us to observe the development of reserve management over time for individual economies. It also includes the data for the United States and the euro-area countries.
Their dataset provides a sample size between those of extant small-sample studies ((McCauley and Chan (2014), Ito et al. (2015), Gopinath and Stein (2018b) and Lu and Wang (2019)) and the dated but near-exhaustive IMF studies (Heller and Knight (1978), Dooley et al. (1989) and Eichengreen and Mathieson (2000)).
The data coverage is also greater and more recent compared to Iancu, et al. (2020).
Aizenman, Ito, and Pasricha (2021) use the data, and Chinn, Ito, and McCauley (2021) updated the dataset.
