While these kinds of liquidity policies protect the companies to a certain extent, they come at the cost of earning a lower yield on those liquid assets. However, the underlying risks may not be identified. The risks are caused by both the liability structure and the exogenous market changes.
Appetite for liquidity risk is often stated as:
• The company maintains liquidity in a 1-in-200-year event over a time horizon of three months.
• The company maintains liquidity at the confidence level of 95 percent while the liquidity cost to meet cash payments at the confidence level of 99.5 percent (1 in 200 years) is less than 25 percent of capital.
