Catch loan stacking, before it's an NPL.

Real-time detection of concurrent loan applications across lenders — also known as credit stacking — so you flag risky borrowers before disbursement, not months after.

Overview

Real-time loan stacking and application velocity detection

A borrower applying to five lenders in one afternoon looks fine to each individual lender — none of them can see what's happening at the other four. By the time all five loans fund, the borrower's real debt load is nothing like what any single underwriting decision assumed, and the risk that gets discovered is usually discovered as a non-performing loan, not a declined application.

Loan stacking detection closes that blind spot by tracking application velocity — how many applications an identity or device is generating, and how close together — across a shared network, in real time. Smile's Monitor stage flags a borrower stacking applications before the second or third loan is approved, using the same velocity-based detection logic that lines up with the transaction-velocity monitoring rules many banking regulators now require, so a lender sees the pattern at the moment it matters instead of reconstructing it after the fact.

Coverage varies by product. Lending-activity and multi-platform signals are available for the Philippines, India, Mexico, Indonesia, Colombia, and Thailand.

What you get

Features

Cross-lender application velocity
Flags multiple loan applications from the same identity or device within a configurable time window, across a shared lender network.
Configurable time windows and thresholds
Tune how aggressive detection is — tighter windows catch fast stacking, wider windows catch borrowers spreading applications over days.
Regulatory-aligned velocity monitoring
Uses the same detection logic that satisfies transaction-velocity monitoring requirements many banking regulators now mandate, so fraud and compliance needs are covered together.
Real-time underwriting flags
Stacking signals surface during the application itself, in time to affect a decision — not in a bureau report reviewed after funding.
No separate integration
Runs on the same profile and API as identity and income verification, so no additional vendor relationship is required.
Why it matters

Benefits

Prevent non-performing loans before they fund
Catching stacking at application time stops overextended borrowers from being approved in the first place, rather than managing defaults after disbursement.
See risk bureau data can't show yet
Real-time velocity detection surfaces stacking before it shows up in a credit bureau file, which often lags actual application activity.
Tune detection to your risk appetite
Configurable windows and thresholds let conservative and aggressive lenders both set detection sensitivity that fits their portfolio.
Dual-purpose compliance coverage
The same velocity monitoring that catches stacking also satisfies the transaction-velocity monitoring requirements many banking regulators now mandate for supervised financial institutions.
FAQ

Common questions

How does loan stacking detection actually work?

Smile tracks application velocity — how many loan applications an identity or device has submitted, and how close together — across a network of lenders, flagging patterns like multiple applications within a short window that suggest a borrower is stacking credit before any single lender can see the full picture.

Can the detection window and thresholds be adjusted?

Yes. Time windows and match thresholds are configurable, so a lender can tune how aggressive detection is — a tighter window catches faster stacking, a wider one catches more patient borrowers spreading applications over days instead of hours.

Does loan stacking detection require a separate integration?

No. It runs on the same profile and API as identity verification and income data, so a lender already using Smile for onboarding gets loan stacking signals without adding a second vendor or integration.

How is this different from a standard credit bureau inquiry check?

A bureau inquiry check shows past applications after the fact, often with a lag. Smile's velocity-based detection flags stacking in real time, at the moment of application, using the same detection logic many banking regulators now require for transaction-velocity monitoring — so a lender can act before disbursement, not after reviewing a bureau report days later.
