As with the credit risk capital requirements, the market risk capital requirements apply on a worldwide consolidated basis. Only a bank, which is running a global consolidated book, may apply the offsetting rules contained in the remainder of these regulations, on a consolidated basis with the prior written agreement of the Central Bank. However, where it would not be prudent to offset or net positions within the group, for example where there are obstacles to the quick repatriation of profits from a foreign subsidiary or where there are legal and procedural difficulties in carrying out the timely management of risks on a consolidated basis, the Central Bank will require the bank to take individual positions into account without any offsetting.
