One vintage, from 87 early defaults to a signed report
Lanternfield Bank booked 4,812 personal loans in August. 87 of them are now 30 days late on their first payment — 1.81% against 1.06% for the six vintages before. Here is how the senior credit risk analyst finds out why, screen by screen, in the working solution.
- 01Monday 2 Nov
A rate that nearly doubled, and no reason yet
Priya Raman · Senior credit risk analystPriya opens the August vintage: 87 early defaults, $1,268,450, causes due Fri 6 Nov. Only what the systems already know can branch the tree — channel and partner — and every leaf reads “Not explained yet”. Fernway Lending Network is 13% of the loans and 38% of the early defaults, 5.14% against its 3.0% contract trigger.
“The channel says where it happened; only the files say why.”

“Re-read the 87 files”
The six agentsThe early default monitor has already assembled each file: application, documents, verification results, the decision record, fraud checks, channel and every payment attempt. Priya presses one button and the agents read them, step by step, with the progress in the tree’s header and the run log in the side rail.
“3 of 6 · one ring of 19 loans on 4 devices”

One branch thickens: the income check was waived
The six agentsThe tree regrows by underwriting exception. 36 of the 87 went through the instant-decision path IV-W, which accepts stated income with a pay-stub image and no payroll or bank-data check. Waived loans defaulted early at 3.25%; loans with income checked, at 1.38%. The waiver runs through the ring, the first-party fraud and the CP-26-07 credit misses alike.
“Income verification waived — 41% of early defaults this quarter”
- 04Branch by cause
Three problems, not one
Priya Raman · Senior credit risk analystSwitched to the cause found, the tree splits: fraud 34 loans ($551,300), credit 29 ($389,250), onboarding 16 ($214,700) and hardship 8 ($113,200). Each leaf opens its loans with the reason the agents found in each file.
“Fraud is the thickest branch — 34 of 87, and 19 of them are one ring.”
- 05The list
87 causes proposed, 8 left for her to read
Priya Raman · Senior credit risk analystThe early defaults list shows the run log of how the 87 were explained and the patterns found — ring R-0926, rule CP-26-07, autopay never saved on Android app 6.14 — each with its owner. 79 causes are at 90% confidence or more and can be confirmed together; the 8 below are read one by one. The review clock shows 4 days left.
- 06One loan
Tyler R. Quinlan, $18,500 — and not one payment
Priya Raman · Senior credit risk analystPL-2608-41377 came through Fernway sub-source FW-2207 and was approved automatically: score 702, debt-to-income 31.0%, fraud score 412 with review from 600. The timeline flags what the decision missed — device DV-7F3A on 6 other applications, a pay stub made from the same template as 18 others, an employer phone that is an internet line registered 9 Jul, a bank account opened 19 days before applying. Proposed cause: fraud, ring R-0926, 96% confidence.
“A borrower in trouble usually pays once.”
- 07The pattern
Ring R-0926: 19 loans, $338,400, no payment ever made
Lena Hoffmann · Fraud strategy managerThe link map ties the 19 loans to 4 devices, 3 receiving bank accounts opened in July, 2 employers with one pay-stub template and 11 employer phone numbers that are internet lines. All 19 came from FW-2207. Four September loans carry the same signals and two applications are still open, ready to hold for review. The suspicious activity report clock runs 30 days from detection on 2 Nov.
The link analyst never blocks an account or files a report — it prepares the referral for the BSA team.
- 08The rule
Which rule let them in, and what tightening it costs
Marcus Bell · Credit policy managerCP-26-07 raised the debt-to-income cap for scores 640–679 from 40% to 45% on 14 Jul. August booked 412 loans in that band above the old cap; 21 defaulted early — 5.10%, against 1.62% below 40%. In the what-if, a 42% cap with a $1,800 monthly residual-income floor declines 268 of the 412 and avoids 17 of the 21 early defaults; the 144 loans kept would default at 2.8%.
The credit rule tracer never changes a rule. Every proposal goes through fair-lending review first.

Each fix to the person who owns it
Priya Raman · Senior credit risk analystFour fixes, each with its evidence and what it costs: close the ring and the door it came through (Lena Hoffmann), amend CP-26-07 and end the income waiver (Marcus Bell), fix the borrowers the bank made late (Renee Alvarez), and a Fernway partner review (Jordan Ellis). Nothing leaves until Priya sends it; Lena is the first to accept.
- 10Signed
The October report, signed for the committee
Daniel Okoro · Consumer Credit Risk DirectorThe cause and fix writer drafts the October early default report for the credit risk committee on Tue 10 Nov: what happened, the rate without the ring and the app defect (1.08%), the thread through all three, fixes and owners. Priya confirms all 87 causes and sends it; Daniel signs.
