Our measures of domestic prudential regulations cover three aspects of macroprudential policy: maximum loan-to-value (LTV) ratios; existence of reserve requirements; and limits on credit concentration to specific sectors. While the existence of maximum LTV ratios and sector-specific credit concentration limits are coded by binary variables, the reserve requirement measure is coded as 0 if the reserve requirement ratio is below 10%; 0.5 if it is in the range of 10–20%; and 1 if it is greater than 20%. Between 2005 and 2007, the prevalence of domestic prudential regulations increased acrossall regions. Nevertheless, Asian EMEs appear to rely the most on domestic macroprudential measures, while European EMEs the least.
