Assess whether a claims ring exists or is coincidental overlap (358094)

Situation

The desk packet is ACH return-reason code R10 spike after a 400% utilization jump in 11 days. Synthetic-identity detection manager in a mortgage correspondent channel has to name A claims ring exists or Is coincidental overlap for this Fraud Detection Payments Fraud file.

Decision

Synthetic-identity detection manager in a mortgage correspondent channel must choose A claims ring exists / Is coincidental overlap using ACH return-reason code R10 spike after a 400% utilization jump in 11 days.

Hypotheses to test

• A 400% utilization jump in 11 days is noise around an already-controlled Payments Fraud process in a mortgage correspondent channel, given ACH return-reason code R10 spike.
• A 400% utilization jump in 11 days is the event in ACH return-reason code R10 spike that forces A claims ring exists for synthetic-identity detection manager under Fraud Detection.
• ACH return-reason code R10 spike shows a one-file miss after a 400% utilization jump in 11 days, not a Payments Fraud program failure.
• ACH return-reason code R10 spike cannot decide a claims ring exists yet after a 400% utilization jump in 11 days; hold is the only Fraud Detection close a mortgage correspondent channel can defend.

Analysis required

• Quantify loss if the hold is released before ACH return-reason code R10 spike is complete.
• Test a one-off dispute against the first edge of a scheme around a claims ring exists.
• Check mule or round-trip markers in ACH return-reason code R10 spike.
• For this Fraud Detection Payments Fraud file, read ACH return-reason code R10 spike against a 400% utilization jump in 11 days and write the one fact that would move a claims ring exists for synthetic-identity detection manager.

Recommendation

Choose A claims ring exists / Is coincidental overlap on this Fraud Detection / Payments Fraud packet (ACH return-reason code R10 spike after a 400% utilization jump in 11 days). The follow-on Payments Fraud action is what synthetic-identity detection manager does next: implement the option, assign an owner, and log the missing fact.
