Exchange rate regime classification, monthly, 1946 - 2019汇率制度分类，月度数据，1946-2019

Compiled by Ilzetzki, Reinhart, and Rogoff (2019) and updated to 2019, this monthly panel database provides authoritative de facto exchange rate regime classifications across global economies from 1946 to 2019. Distinct from official de jure classification standards, it adopts two-tier fine and coarse classification systems to categorize currency regimes, covering hard pegs, soft pegs, managed floats, free floats, high-inflation free-falling regimes, and dual exchange rate arrangements. The dataset further records anchor currency types and capital control conditions, effectively correcting deviations between stated exchange rate policies and actual market practices, and has become the mainstream empirical dataset for international macroeconomics and exchange rate regime research.

本数据库由Ilzetzki、Reinhart与Rogoff（2019）构建并更新至2019年，涵盖1946–2019年全球经济体的月度实际汇率制度分类数据。区别于官方名义汇率制度统计，数据库采用精细、粗放双层分类标准，划分出硬钉住、软钉住、管理浮动、自由浮动、高通胀自由坠落及双重汇率制度六大类别，同时收录锚定货币类型与资本管制状态核心指标。该数据精准修正了各国汇率政策声明与实际运行的偏差，是国际宏观经济、汇率制度相关实证研究的主流权威数据源。
