What is liquidity?
Liquidity is the efficiency or convenience with which a security or asset can be turned into quick cash without negatively impacting its market price. Cash alone is the most liquid asset. As a result, the primary factor determining how well a market functions is the availability of funds for these conversions.
An asset may be converted back into cash more quickly and easily the more liquid it is. More time and money may be spent on less liquid assets.
Recognizing Liquidity
Put differently, liquidity is the extent to which an item may be readily purchased or sold on the market at a price that accurately reflects its inherent value. Cash is usually regarded as the most liquid asset because it can be changed into other assets the quickest and easiest. Real estate, fine art, and collectibles are tangible goods that are not very liquid. Various other financial instruments, such as partnership units and stocks, occupy the liquidity spectrum.
Cash, for instance, is the asset that can most readily be utilized to buy a $1,000 refrigerator. That person is unlikely to locate someone ready to sell the refrigerator for their $1,000 rare book collection if they have no cash, but the collection is valuable. Instead, they must sell the collection and pay for the refrigerator with the proceeds.
That might not be an issue if the buyer has just days to make the purchase, but it might be if they can wait months or years. They may have to sell the books at a discount instead of waiting for a customer who is prepared to pay the total amount. An example of an illiquid asset is rare books.
Market Transparency
Market liquidity refers to the extent to which a market, such as a country’s stock market or a city’s real estate market, permits assets to be purchased and sold at steady, transparent prices. In the case above, the market for refrigerators in exchange for rare books is so illiquid that it does not exist.
The stock market, on the other hand, is characterized by more market liquidity. If an exchange has a significant volume of activity not dominated by selling, the price that a buyer offers per share (the bid price) and the price that the seller is ready to take (the asking price) will be close.
Consequently, investors won’t have to forfeit unrealized gains in exchange for a speedy sale. The market is more liquid when the difference between the ask and bid prices narrows; it becomes more illiquid when it widens. Compared to stock markets, real estate markets are typically significantly less liquid. The size and number of open exchanges on which other assets can be traded determine the liquidity of those markets. Examples of these assets include derivatives, contracts, currencies, and commodities.
Financial Liquidity
Accounting liquidity quantifies how easily a person or business may pay off debts when they become due by using their liquid assets to meet their financial commitments.
The rare book collector in the example mentioned above has illiquid assets; thus, they probably wouldn’t be worth their entire $1,000 value in an emergency. Comparing liquid assets to current liabilities, or debts due within a year, is evaluating accounting liquidity in the context of investments.
Several ratios measure accounting liquidity, each with a different definition of liquid assets. Investors and analysts use these to find companies with high liquidity. It is regarded as a depth measure as well.
Assessment of Liquidity
Financial analysts consider a company’s capacity to pay short-term obligations with liquid assets. Generally, a ratio more significant than one is preferred when utilizing these calculations.
Existing Ratio
The most accessible and least restrictive ratio is the present ratio. It measures current assets (those that can reasonably be converted to cash in one year) against current liabilities. Its equation would be:
Current Ratio = Current Assets ÷ Current Liabilities
Acid-Test Ratio, or Quick Ratio
A little stricter is the quick ratio, often known as the acid-test ratio. It does not include current assets like inventory, which is less liquid than cash and cash equivalents, short-term investments, and accounts receivable. The equation is:
Quick Ratio = (Cash and Cash Equivalents + Short-Term Investments + Accounts Receivable) ÷ Current Liabilities
Acid-Test Ratio (Variation)
A variation of the quick/acid-test ratio subtracts inventory from current assets, making it a bit more generous:
Acid-Test Ratio (Variation) = (Current Assets + Inventories + Prepaid Costs) ÷ Current Liabilities
Cash Ratio
The cash ratio is the most exacting of the liquidity ratios. Excluding accounts receivable, inventories, and other current assets, it defines liquid assets as cash or cash equivalents.
More than the current ratio or acid-test ratio, the cash ratio possesses an entity’s ability to stay solvent in an emergency—the worst-case scenario—because even highly profitable companies can run into trouble if they do not have the liquidity to react to unforeseen events. Its formula is:
Cash Ratio = Cash and Cash Equivalents ÷ Current Liabilities
Liquidity Example
In terms of investments, equities are among the most liquid assets. However, not all equities are created equal when it comes to liquidity. Some shares trade more actively than others on stock exchanges, meaning there is more of a market for them. In other words, they attract greater, more consistent interest from traders and investors.
These liquid stocks are usually identifiable by their daily volume, which can be in the millions or even hundreds of millions of shares. When a stock has a high volume, it means that there are many buyers and sellers in the market, making it easier for investors to buy or sell the stock without significantly affecting its price. On the other hand, low-volume stocks may be more complicated to buy or sell, as there may be fewer market participants and, therefore, less liquidity.
For example, on March 13, 2023, 69.6 million shares of Amazon.com Inc. (AMZN) traded on exchanges. By comparison, Intel Corp. (INTC) saw a volume of just 48.1 million shares, indicating it was somewhat less liquid. But Ford Motor Co. (F) had a volume of 118.5 million shares, making it the most active, and presumably most liquid, of these three stocks on that day.
Why is liquidity necessary?
If markets are liquid, selling or converting assets or securities into cash becomes easier. You may, for instance, own a very rare and valuable family heirloom valued at $150,000. However, if there is no market (i.e., no buyers) for your object, it is irrelevant since nobody will pay anywhere close to its appraised value—it is very illiquid. It may even require hiring an auction house to act as a broker and track down potentially interested parties, which will take time and incur costs.
Liquid assets, however, can be easily and quickly sold for their total value with little cost. Companies must also hold enough liquid assets to cover their short-term obligations like bills or payroll; otherwise, they could face a liquidity crisis, leading to bankruptcy.
What Are the Most Liquid Assets or Securities?
Cash is the most liquid asset, followed by cash equivalents, such as money market accounts, certificates of deposit (CDs), or time deposits. Marketable securities, such as stocks and bonds listed on exchanges, are often very liquid and can be sold quickly via a broker. Gold coins and certain collectibles may also be readily sold for cash.
What Are Some Illiquid Assets or Securities?
Securities traded over the counter (OTC), such as certain complex derivatives, are often relatively illiquid. For individuals, a home, a timeshare, or a car are all illiquid in that it may take several weeks to months to find a buyer and several more weeks to finalize the transaction and receive payment. Moreover, broker fees tend to be extensive (e.g., 5% to 7% on average for a real estate agent).
Why Are Some Stocks More Liquid Than Others?
The most liquid stocks are those with great interest from various market actors and daily transaction volumes. Such stocks will also attract a greater number of market makers who maintain a tighter, two-sided market.
Illiquid stocks have wider bid-ask spreads and less market depth. These names tend to be less known, have lower trading volume, and often have lower market value and volatility. Thus, the stock of a large multinational bank will tend to be more liquid than that of a small regional bank.
The Bottom Line
Liquidity is the ease of converting an asset or security into cash, with cash being the most liquid asset. Other liquid assets include stocks, bonds, and other exchange-traded securities. Tangible items tend to be less liquid, meaning they can take more time, effort, and cost to sell (e.g., a home).
Conclusion
- Liquidity is the ease with which an asset or security can be changed into immediate cash without impacting its market price.
- The most liquid asset is cash, while physical objects are less liquid.
- Market liquidity and accounting liquidity are the two basic types of liquidity.
- The most frequent liquidity ratios are current, quick, and cash.
