Cash Margin refers to cash collateral or margin deposited by the borrower against a non-fund or fund-based facility. It reduces the bank’s net exposure and supports risk mitigation. Mention whether the margin is lien-marked and linked to a specific facility. In MSME underwriting, it is read as part of the financial assessment and is usually compared across periods, peers, banking conduct and management explanations. For example, a rising margin can show pricing power, while a sudden fall may point to cost pressure, discounting or weak operating control. It matters because the number can influence eligibility, limit sizing, repayment comfort, leverage view and early-warning assessment. The common mistake is to use it mechanically; seasonality, accounting treatment, one-off items and data mismatches can change the credit interpretation.
