Liquidity refers to the ease at which assets can be converted into cash.
- An asset is said to be liquid if it is easy to buy and sell; for example, short-date government gilts are a highly liquid market because it is easy to sell on the bond markets.
- As asset is said to be illiquid if it is difficult to buy and sell. For example, a house is a very illiquid asset because to sell a house requires considerable time and expense. By the time you have found a buyer, the price of a house may have changed considerably – especially during boom and busts.
The importance of liquidity
An investor may need both liquid and illiquid assets. You need liquid assets to deal with any unexpected short-term crisis. But, illiquid assets may offer a greater chance for capital gains and higher yield.
For example, if you put money in a current account, you have instantaneous access, but interest rates tend to be low. If you put money in a time deposit account, you have to give the bank a seven day or 30-day advance warning you need the money. This makes your savings more illiquid, but the bank compensates by paying a higher interest rate.
A liquidity ratio refers to the number of liquid assets to overall assets. If a firm is highly liquid – it has a high proportion of assets that can easily be converted to cash to pay off any obligations.
A low liquidity ratio means a firm has a shortage of liquid assets and may struggle to meet short-term debt obligations.
Cash reserve ratio
A bank may be required to keep a certain percentage of its assets in the form of liquid assets. It is the fraction of customer deposits held in cash reserves.
Cash reserves are not profitable. If a bank lends deposits to other customers, it can charge interest and make more profit. But bank loans are highly illiquid because the bank cannot immediately ask for the loan back.
A problem of the credit crisis is that banks had a very low cash-reserve ratio. This led to a liquidity crisis when banks couldn’t raise sufficient funds on short-term money markets.
Liquidity and insolvency
Sometimes firms or governments may find they face a liquidity crisis – even though fundamentally they have a decent financial position.
For example, a firm may in theory be profitable – its revenue is greater than its costs. However, if the firm has not received its income due – because of later payers, it can find itself with a cash-flow problem. It doesn’t have enough income to meet current bills. This is a liquidity problem. Given time, it could sell assets and collect the late payments. But in the short-term it lacks liquidity.
On the other hand, if a firm has revenue substantially below costs, it will become insolvent in the long-term. The problem is more than just a liquidity problem.
In the Euro crisis, several European economies, such as Ireland and Italy suffered a liquidity crisis – they couldn’t borrow on short-term money markets to finance their current shortfalls because of a lack of confidence.
In the UK, we had higher levels of government borrowing. But, because the UK had a Central Bank able to print money – we had greater liquidity and investors had more confidence. Therefore the UK didn’t face a liquidity shortage.
When a cut in interest rates fails to stimulate consumer spending because consumers prefer to hold money (liquid assets) rather than spend and buy illiquid goods. See: Liquidity trap explained
