Directive 2006/49/EC of the European Parliament and of the Council (repealed)Dangos y teitl llawn

3.1. The competent authorities may allow institutions to provide lower capital requirements against positions in closely correlated currencies than those which would result from applying points 1 and 2 to them. The competent authorities may deem a pair of currencies to be closely correlated only if the likelihood of a loss — calculated on the basis of daily exchange‐rate data for the preceding three or five years — occurring on equal and opposite positions in such currencies over the following 10 working days, which is 4 % or less of the value of the matched position in question (valued in terms of the reporting currency) has a probability of at least 99 %, when an observation period of three years is used, or 95 %, when an observation period of five years is used. The own‐funds requirement on the matched position in two closely correlated currencies shall be 4 % multiplied by the value of the matched position. The capital requirement on unmatched positions in closely correlated currencies, and all positions in other currencies, shall be 8 %, multiplied by the higher of the sum of the net short or the net long positions in those currencies after the removal of matched positions in closely correlated currencies.
