The cash ratio is the most conservative of the liquidity ratios, measuring a company's ability to meet its immediate short-term obligations using only its most liquid assets — cash and cash equivalents (such as treasury bills and short-term government securities) — without relying on receivables, inventory, or other current assets that may take time to convert to cash. It is calculated as: Cash Ratio = (Cash + Cash Equivalents) ÷ Current Liabilities. A cash ratio of 1.0 or above means the company can pay off all its current liabilities immediately using cash alone. While a high cash ratio signals financial strength and liquidity cushion, an excessively high cash ratio may indicate poor capital allocation — the company is holding too much idle cash rather than deploying it productively in the business or returning it to shareholders. In Indian equity analysis, the cash ratio is particularly examined for highly leveraged companies or those in cash-flow-intensive sectors like infrastructure and real estate, where near-term liquidity is a critical solvency concern.
