Emerging Corridor Fraud Surge
CD, AO, ET corridors showing 6.8–8.2 bps fraud — 2.5× platform average. Fraud model flags these clusters but real-time intervention is absent.
Recommendations
↗ Deploy real-time Snowpark UDF fraud scoring at submission — block transactions scoring above 0.75 threshold
↗ Enforce LEVEL_2 KYC minimum for CD/AO/ET before allowing transactions > R 500
↗ Add velocity rule: flag > 3 failed attempts in 10 min per customer
Estimated fraud reduction: −35% bps in 90 days
Zimbabwe Volume vs Low Success Rate
ZA-ZW is the largest corridor (R 18.4B) but success rate is only 78.2% — 4pp below premium corridors. Each 1pp improvement = R 184M additional completions.
Recommendations
↗ Add mobile money payout option (EcoCash) alongside cash — reduces failure caused by agent unavailability
↗ Pre-validate recipient account details at submission using ZWG bank API
↗ Add retry logic with alternative payout rail after 30-min timeout
Revenue upside if success → 82%: +R 736M/year
Churn Model — 10.9% at Risk
Churn model (AUC 0.9905) identifies 54,500 customers as high churn risk. Top signal: 42% importance from "days since last transfer" — inactivity is the key driver.
Recommendations
↗ Trigger automated win-back campaign at day 21 of inactivity (before the 30-day cliff)
↗ Offer fee waiver on next transfer for customers with engagement_score < 40
↗ Push wallet balance nudge via USSD/app for customers with balance > R 50 but zero sends in 14 days
Retention of 10% of at-risk = 5,450 customers saved
IFRS 9 ECL — Stage Migration Risk
Credit model (AUC 0.9475) shows 37.4% default rate in training data. DTI ratio (35.8% importance) and prior DPD (28.1%) are dominant. IFRS 9 Stage 2 migration threshold needs review.
Recommendations
↗ Set automatic Stage 2 trigger when PD score > 0.35 (current model threshold)
↗ Reject applications where DTI > 0.45 and prev_dpd > 30 — reduces ECL exposure
↗ Implement Early Warning System: Snowpark scoring at 7-day intervals
ECL reduction estimate: −15–20% provision
Premium Corridor FX Margin Expansion
Lesotho, Eswatini, Mauritius corridors carry 6.05–6.44% FX spreads with 80–87% success rates. These "Premium" corridors are underinvested in marketing volume.
Recommendations
↗ Increase marketing spend on MU/LS/SZ corridors — higher margin, lower fraud (0.9–1.8 bps)
↗ Launch Premium loyalty tier for customers transacting exclusively on premium corridors
↗ Partner with Mauritian banks for bulk settlement to reduce interbank costs
Volume uplift target: +25% in 6 months
KYC Completion Gap — 18% Unverified
82% KYC completion means 90,000 customers at LEVEL_0/1. These customers have 3× higher fraud rates and lower LTV. KYC is also the #4 fraud feature (10.2% importance).
Recommendations
↗ Implement progressive KYC: gate R 1,000+ transactions behind LEVEL_2 (ID verification)
↗ Build dbt mart_kyc_funnel to track weekly KYC conversion by channel and corridor
↗ Add Snowflake alert: trigger when corridor KYC completion drops below 70%
KYC uplift to 90% = fraud bps −1.2, LTV +8%
