For currencies that do not have sufficient HQLA, as determined by reference to the qualifying principles and criteria, Option 2 would allow supervisors to permit banks that evidence a shortfall of HQLA in the domestic currency (which would match the currency of the underlying risks) to hold HQLA in a currency that does not match the currency of the associated liquidity risk, provided that the resulting currency mismatch positions are justifiable and controlled within limits agreed by their supervisors. Supervisors should restrict such positions within levels consistent with the bank’s foreign exchange risk management capacity and needs, and ensure that such positions relate to currencies that are freely and reliably convertible, are effectively managed by the bank, and would not pose undue risk to its financial strength. In managing those positions, the bank should take into account the risks that its ability to swap currencies, and its access to the relevant foreign exchange markets, may erode rapidly under stressed conditions. It should also take into account that sudden, adverse exchange rate movements could sharply widen existing mismatch positions and alter the effectiveness of any foreign exchange hedges in place.
