This paper presents and analyses new datasets of de jure Currency-Based Measures (CBMs) directed at banks in a sample of 49 countries between 2005 and 2013. These measures are bank regulations that apply a discrimination−e.g. a less favourable treatment−on the basis of the currency of an operation, typically foreign currencies. The new data shows that CBMs have been increasingly used in the post-crisis period, including for macro-prudential purposes. In particular, some Emerging Market Economies, including some OECD countries, have increasingly resorted to and tightened their CBMs, especially to manage capital inflows. Information from these new datasets is also matched with measures on countries’ inability to borrow in domestic currency on international markets, defined as the original sin concept. With the exception of China, only countries suffering from original sin used and tightened CBMs on banks’ foreign exchange liabilities.
