Where once an insurer's chief investment officer (CIO) reigned supreme over assets-aided and sometimes hindered by the involvement of a chief risk officer (CRO)-these days managing portfolio risk and return seems to be an altogether more complex affair. No less of this complexity has come from the expansion by insurers into illiquid assets in the last decade. Moving away from traditional assets has raised scrutiny of liquidity risk management, but how do insurers tackle this? In a world 'brimming with large and growing portfolio allocations to illiquid private assets,' liquidity management concerns are distinct from a typical CRO's portfolio or asset risk orientation. There's a need to look at all aspects of a fund's liquidity demands and sources, such as top-down asset allocation, bottom-up private market deal-making activities, and internal and external operations. A dedicated liquidity management function should also be able to identify both explicit and potential liquidity demands and sources and, in particular, stay in touch with market movements and the regulatory environment. It should identify, evaluate and keep at-the-ready possible external liquidity facilities-for example, the secondary market for private equity stakes, a collateralized portfolio liquidity line, a repurchase agreement or a futures program. A high-quality liquidity management team can also identify when a fund has too much liquidity, the cost of being overly cautious and how to put excess liquidity to work.
