Need for Car Insurance Deductible Reform to Curb Over-Repair

The Erosion of South Korea’s Deductible Buffer

South Korea’s automotive insurance industry is facing calls for systemic reform. The current policyholder deductible system, known as jagi-budamgeum, is no longer curbing excessive repair claims. Originally designed to discourage unnecessary repairs, it is argued that the mechanism has lost its effectiveness and needs improvement to fit current realities.

The Moral Hazard Dilemma

The system requires policyholders to pay a portion of repair costs when filing a claim.

Typically, the deductible is a percentage of the total repair cost, subject to specific minimum and maximum thresholds.

Tech Complexity Inflates Repair Bills

The system’s effectiveness has crumbled under the weight of modern vehicle technology.

Because the cost of minor accidents involving sensors or specialized paint finishes is now substantially higher, the fixed-rate deductible represents a smaller fraction of the total claim than when the system was first implemented. This has created a feedback loop:

• High Repair Costs: Advanced components mean standard labor and parts prices remain elevated.
• Diminished Deterrence: Because the relative burden of the deductible has decreased, policyholders are less discouraged from filing claims for minor damages.
• Premium Pressure: The resulting increase in claim frequency puts upward pressure on annual insurance premiums for all policyholders.

Proposed Paths for Regulatory Overhaul

Industry stakeholders and consumer advocacy groups are now weighing reforms to restore the system’s original intent.

1. Dynamic Deductible Scaling: Linking the minimum deductible amount to the vehicle’s market value or the specific technology integrated into the damaged area, rather than applying a blanket percentage.
2. Tiered Claims Impact: Implementing a more aggressive “no-claims bonus” system that penalizes frequent, low-value claims more heavily than a single, high-value accident.
3. Standardized Repair Guidelines: Strengthening oversight on repair shops to prevent “over-repairing”—where shops replace entire modules instead of repairing individual parts—which bypasses the deterrent effect of the deductible.

A Shift Toward Driver Responsibility

Regulators face a delicate balancing act: controlling costs without stripping away essential consumer protections. Any increase in mandatory deductibles risks backlash from consumer rights groups who may view the change as a reduction in coverage.

Insurance companies are currently under pressure to improve loss ratios and stabilize premiums. For policyholders, the takeaway is clear: the era of “no-cost” minor repairs is likely coming to an end, with future policy updates expected to shift more financial responsibility toward the driver for non-essential vehicle restoration.
