Debt Restructuring Viability is an assessment of whether a stressed borrower can recover under revised repayment terms, moratorium, rescheduling, or other restructuring support without simply delaying default. In MSME credit, it converts borrower behaviour, financial signals, compliance gaps or business dependencies into a clearer risk view for approval and monitoring. For example, stable orders, diversified customers, manageable debt and experienced promoters support viability, while repeated losses or weak controls reduce comfort. It matters because it helps the lender decide whether to proceed, add conditions, seek mitigants, reduce exposure or monitor the account more closely. The common mistake is to treat the indicator as a final decision by itself; it should be supported by evidence, trend analysis and credit judgement.
