A head of market and liquidity risk runs the second line for the balance sheet: the limits, interest rate risk in the banking book, the liquidity risk appetite, the stress tests behind the ILAAP, and the challenge to the people who take the positions. The role usually reports to the chief risk officer, whose PRA function, SMF4, covers the setting and managing of the firm’s risk exposures.
Two PRA rules anchor it. A firm must at all times maintain liquidity resources which are adequate, both as to amount and quality, and the PRA expects its prescribed responsibilities for capital, funding and liquidity and for treasury management to sit with the senior manager most closely linked to each.
First we settle which job this is, because the title covers three. In a trading firm it means desk limits, value at risk and the daily profit and loss; in a UK bank with little or no trading book it is a liquidity and interest rate job lived at the ALCO. Where the treasurer reports decides who this person challenges, and the strongest candidates ask that first.
