South Korea's Financial Services Commission (FSC) has proposed amendments to its Insurance Business Supervisory Regulations that will require insurers to file annual actuarial assumption reports and fold general agency (GA) channel risk into the regulator's core risk-rating framework – changes that will reshape how brokers and agencies interact with the insurers they represent.

The FSC opened the amendments for public comment from Sept. 11 to Sept. 21 under its regulation-change advance notice process, according to multiple Korean financial trade outlets. The core reforms – GA risk grading and a cap on real estate project financing (PF) exposure – are set to take effect Jan. 1, 2027, pending review by the Regulatory Reform Committee and formal FSC approval. The actuarial assumption report requirement takes effect earlier, on Dec. 31, 2026, while a related change to indemnity health insurance rider rules applies immediately once the FSC formally resolves the amendment.

GA channel risk enters the ratings system

Under the proposal, insurers must submit reports detailing the calculation basis and verification results behind their actuarial assumptions as part of their annual business reports filed with the Financial Supervisory Service (FSS), with any mid-year revisions reported to internal risk management committees. Separately, GA channel operational risk will be folded into the FSC's Risk Assessment and Application System (RAAS), with insurers graded on a 1-5 scale using incomplete-sales ratios and policy persistency rates in GA channels, according to the same outlets. Depending on the grade, insurers could see incentives or penalties applied to their Korean Insurance Capital Standard (K-ICS) ratio calculations.

An FSC official said the reforms are meant to secure transparency in actuarial assumptions and allow early detection of anomalies, according to SafeMoney.

The change ties an insurer's regulatory capital treatment directly to how cleanly business is written and retained through those channels – a shift that adds pressure on GA-linked sales practices without altering commission or licensing structures directly. South Korea's insurance intermediaries, including brokers and agencies, are already required to register with the FSS and comply with the Insurance Business Act's solicitation rules, a framework that governs how business written through GA channels is supervised.

The FSC also plans to introduce a duration gap metric — measuring the difference between asset and liability durations — as a new quantitative indicator of interest rate risk within RAAS, alongside a cap limiting insurers' PF credit exposure to 20% of total assets.

Capital pressure adds context

The reforms arrive as Korean insurers' average K-ICS ratio, including transitional measures, fell to 197.9% in the first quarter of 2025 from 206.7% in 2024, following the regulator's move to lower the K-ICS benchmark from 150% to 130% in June 2025, according to industry analysis. That declining capital buffer adds context for why regulators are tightening actuarial assumption verification and GA-linked risk grading at the same time – both feed directly into the same K-ICS calculation brokers' insurer partners must maintain.

FSS caution to KB Insurance underscores enforcement focus

Separately, the FSS issued a management caution to KB Insurance on Sept. 9, citing inadequate guidance on its accident-free contract conversion program, under which policyholders can move to lower-premium contracts after maintaining accident-free periods. The regulator found the application rate against eligible contracts stood at 41.6%, with a conversion rate of 39.6%, and directed the insurer to improve its guidance procedures and advertising pre-screening controls. The FSS also flagged gaps in KB Insurance's post-hoc advertising monitoring and group insurance discount verification.

Together, the amendments and the KB Insurance case point to a regulator focused on tightening verification and disclosure across the distribution chain – from how insurers calculate liabilities to how GA-sold policies are monitored for quality – a trend brokers operating in the Korean market will need to track as the reforms take effect through Jan. 1, 2027.
