Banks must set internal limits to control the size of their cumulative net mismatch positions (i.e. where cumulative cash inflows are exceeded by cumulative cash outflows), at least for the shorter-term time bands (e.g. next day, 5 to 7 days ahead, 14 days, 1, 2, 3, 6 and 9 months). Such limits must be in line with the established liquidity risk tolerance, and must take into account the potential impact of adverse market conditions on the bank's funding capacity. Maturity mismatch limits must also be imposed for individual foreign currencies in which a bank has significant positions.
