Liquidity risk
Liquidity risk is a financial risk that for a certain period of time at a given financial asset, security or commodity cannot be traded quickly enough in the market without impacting the market price.
Types of liquidity risk
Market liquidity – An asset cannot be sold due to lack of liquidity in the market – essentially a sub-set of market risk. This can be accounted for by:
Widening bid/offer spread
Making explicit liquidity reserves
Lengthening holding period for VaR calculations
Funding liquidity – Risk that liabilities:
Cannot be met when they fall due
Can only be met at an uneconomic price
Can be name-specific or systemic
Causes of liquidity risk
Liquidity risk arises from situations in which a party interested in trading an asset cannot do it because nobody in the market wants to trade for that asset. Liquidity risk becomes particularly important to parties who are about to hold or currently hold an asset, since it affects their ability to trade.
Manifestation of liquidity risk is very different from a drop of price to zero. In case of a drop of an asset's price to zero, the market is saying that the asset is worthless. However, if one party cannot find another party interested in trading the asset, this can potentially be only a problem of the market participants with finding each other. This is why liquidity risk is usually found to be higher in emerging markets or low-volume markets.
