AI moves from pilot to production in finance: faster service, fewer errors
Insurers and banks are pushing AI into everyday operations. The goal is simple: reduce manual load, increase accuracy, and move faster on high-volume work like complaints, claims, and branch services.
The pattern is clear. AI handles the repetitive, information-heavy steps, while people step in for judgment and exceptions. That mix is where the efficiency-and the risk control-actually shows up.
Insurance: from complaints to claims decisions
KB Insurance rolled out an AI complaints assistant that listens to recorded calls, classifies the issue, and routes it to the right process and team. The model learns from both consumer and employee feedback during handling, tightening classification and response quality over time. Legal checks run in real time, so the handoff is cleaner and less error-prone.
Samsung Fire & Marine Insurance uses AI to review complex medical claims (e.g., cancer diagnoses and surgery benefits). It combines OCR and generative models to read diagnosis documents, test results, and medical records at scale. AIA Life is deploying LLM-enabled OCR as an upgrade to its claims and payouts flow, moving more cases through straight-through processing while flagging edge cases for human review.
Banking: smarter property picks and branch automation
KB Kookmin Bank added an AI investment feature to the KB Real Estate platform that analyzes location, transport access, and valuation drivers. It also summarizes key details per listing, making side-by-side comparisons easier and aligning results to each user's preferences based on data.
Shinhan Bank is piloting MOLI, an AI agent active at a Seoul branch that handles 60+ services such as account opening, balance checks, remittances, passcode setup, card and bankbook issuance, and printed certificates. It delivers consistent service and frees staff for higher-value conversations without turning the branch into a queue of paperwork checks.
Across lenders, AI now screens for unusual transactions and blocks voice phishing attempts. Fraud teams get faster alerts with fewer false alarms, and customers see fewer hold-ups on legitimate activity.
What this means for finance teams
AI is no longer a side project. It's becoming core plumbing for service, risk, and operations. If you own P&L or process KPIs, these are the places you'll feel it first.
- Complaint handling: faster triage, more consistent categorization, better legal hygiene.
- Claims: higher first-pass accuracy, clearer audit trails, lower rework rates.
- Fraud: improved detection with tighter false-positive control.
- Branch ops: reduced wait times, fewer handoffs, higher completion rates on routine tasks.
- Property insights: quicker decision support grounded in comparable data.
Implementation playbook (without adding new risk)
- Start with high-volume, rules-heavy tasks. Complaints triage, document review, and property data summarization are ideal.
- Keep humans in the loop. Route exceptions to specialists. Capture their feedback to retrain models and improve prompts.
- Lock down data. Mask PII, restrict prompts, and log every model call. Maintain a clean audit trail for regulators and internal audit.
- Measure quality, not just speed. Track accuracy, rework, escalations, false positives, and customer outcomes. Tie changes to dollars saved and risk reduced.
- Use model risk controls. Validate models, document limitations, monitor drift, and review output sampling. Align with established guidance like the NIST AI Risk Management Framework.
- Plan graceful degradation. If the AI fails or confidence is low, fall back to a simpler rules engine or a human queue, not a hard stop.
Practical KPIs to watch
- Complaint triage SLA and first-contact resolution rate.
- Claims straight-through processing rate and manual override rate.
- Fraud detection precision/recall and customer false-positive impact.
- Branch wait time, abandonment rate, and service completion time.
- Document processing turnaround and error rates (pre/post AI).
Bottom line: AI is taking over the grunt work. The winners will pair it with strong controls, clear KPIs, and a feedback loop that makes the system smarter week by week.
