The price risk in commodities is often more complex and volatile than that associated with currencies. Banks need to guard against the risk that arises when a liability (i.e. in a Parallel Salam transaction) position falls due before the asset position (i.e. a failure associated with or delay in the Salam contract). Owing to a shortage of liquidity in some markets, it might be difficult to close the Parallel Salam position and the bank might be "squeezed by the market". All these commodity market characteristics can result in price transparency and the effective management of risk.
