Much critical attention has been given in recent years to market and credit risks, which have a significant effect on corporate and financial operations and must be understood and managed with care. While these areas have rightly received considerable scrutiny, another critical dimension of financial risk - based on corporate liquidity - has been largely overlooked. Liquidity risk is the risk of loss arising from an inability to quickly realise asset value or obtain funding and can be damaging if not properly considered or actively managed. Lack of liquidity can lead to large losses in asset/liability portfolios and off balance sheet activities and in extreme cases can trigger financial distress and insolvency. Liquidity Risk is a comprehensive treatment of the topic focusing on the nature of the risk, problems that arise in asset and funding liquidity and mechanisms that can be developed to monitor, measure and control such risks.
