There is no capital charge for market risk to be applied in addition to provisions in Paragraphs CA-3.4.13 to CA-3.4.19, subject to there being no provisions in the Parallel Istisna'a contract that allow the seller to increase or vary its selling price to the Islamic bank licensee, under unusual circumstances. Any variations in a Parallel Istisna'a contract that are reflected in the corresponding Istisna'a contract which effectively transfers the whole of the price risk to an Istisna'a customer (buyer), are also eligible for this treatment.
