Businesses are encouraged to look at CLIENT relationships in the round and not solely at each of their risk characteristics in isolation to one another.
Even if a client is considered low risk in isolation the combination of risks in combination may highlight something else – In risk management terms, this is referred as the CONFLUENCE OF RISK FACTORS.
Boards are encouraged to be alive to this and ask the business how they go about managing this type of risk and whether their risk assessment process looks at customer risk in the round.
This matter was raised by the GFSC in a recent paper = http://bit.ly/1vKg4Fy
