Why is the current ratio used as a liquidity measure, and what are its limitations?

• A. Current ratio = current assets / current liabilities; it indicates short-term liquidity but can be distorted by inventory valuation or off-balance sheet items.
• B. Current ratio = cash / debt; shows profitability.
• C. Current ratio = accounts receivable / accounts payable; shows revenue growth.
• D. Current ratio = total assets / total liabilities; shows solvency.

Answer: (B)

The current ratio is a simple gauge of short-term liquidity: it compares assets expected to be converted to cash within a year (current assets) with obligations due within that same period (current liabilities). A ratio above 1 suggests the firm has more near-term resources than near-term debts, signaling a cushion to cover upcoming obligations and a basic level of liquidity. But there are important limits to rely on this measure alone. It includes items like inventory that may be difficult to sell quickly or at full value, so a high ratio can reflect overstocked or slow-moving inventory rather than true liquidity. It also lumps together assets that are not equally liquid, such as prepaid expenses or marketable securities, and it doesn’t show the timing of cash flows—only balances. Some current assets might be funded by lines of credit or credit arrangements not fully captured in the balance sheet, masking liquidity risk. Differences in accounting practices and industry norms can make ratios hard to compare across firms. Because of these issues, many analysts supplement the current ratio with the quick ratio (which excludes inventory), the cash ratio, and a review of operating cash flow to get a clearer picture of liquidity.
