Conditional Prepayment Rate
Conditional Prepayment Rate is a structured-finance concept used to describe how borrower repayment behavior changes the timing, duration and valuation of mortgage or asset-backed cash flows.

How Conditional Prepayment Rate works
In practice, the result depends on the transaction documents, collateral performance, payment priority and the triggers that can redirect cash flows. Analysts therefore connect Conditional Prepayment Rate to the waterfall, enhancement levels and servicing assumptions rather than viewing it in isolation.
Why it matters in markets
Conditional Prepayment Rate matters because securitized cash flows are path-dependent. Prepayments, defaults, recoveries, servicing actions and structural triggers can change duration and principal return even when the collateral pool initially looks similar.
How to interpret Conditional Prepayment Rate
Interpret Conditional Prepayment Rate through the transaction waterfall and collateral assumptions. Check which class absorbs losses first, which triggers redirect cash, how quickly principal can return and whether servicing or prepayment behavior changes the expected path.
Limits and context
Conditional Prepayment Rate can vary materially across deals. Prospectuses, pooling and servicing agreements, indentures and trustee reports determine the actual mechanics; generic market definitions should not replace transaction-level analysis.
