Slippage Probability Index is a risk-monitoring concept used to identify stress, control weakness or portfolio-level concern. In risk and portfolio monitoring, it helps identify early warning signals, control gaps, borrower stress or conditions that need closer follow-up. The assessment should connect the signal to a clear action such as additional verification, tighter covenants, lower exposure, pricing change or enhanced monitoring. For example, repeated overdue interest, excess drawings and falling turnover may increase the probability that an account slips into stress. It matters because risk indicators are useful only when they trigger timely review, mitigation, documentation and follow-up action. The common caution is to avoid mechanical scoring; the reason, trend, source data and proposed mitigant should be recorded clearly.
