Article 141
Domestic and foreign currency items
A credit assessment that refers to an item denominated in the obligor's domestic currency cannot be used to derive a risk weight for another exposure on that same obligor that is denominated in a foreign currency.
When an exposure arises through an institution's participation in a loan that has been extended by a multilateral development bank whose preferred creditor status is recognised in the market, the credit assessment on the obligors' domestic currency item may be used for risk weighting purposes.
