South Korea’s five largest non-life insurers – Samsung Fire & Marine Insurance, DB Insurance, Meritz Fire & Marine Insurance, Hyundai Marine & Fire Insurance, and KB Insurance, all headquartered in Seoul – reported combined net profit of 5.82 trillion won (approximately US$4.0 billion, per Seoul Economic Daily) for the nine months to September 2026, up 5.5% year-on-year, according to earnings reports published on November 13, 2026, by Seoul Economic Daily.
Three carriers gained ground on stronger underwriting. Two lost it. A single quarter of equity market losses was enough to cancel progress the core business had spent most of the year building.
For brokers placing motor and long-term lines business with Korean carriers, the split is the signal: when underwriting margins improve but investment returns collapse in the same quarter, carriers face immediate pressure to tighten claims handling and reconsider pricing – and those effects reach placement conversations faster than year-end figures suggest.

Samsung Fire & Marine posted cumulative net profit of 1.6942 trillion won, up 15.8% year-on-year. Insurance earnings rose 10.7% to 1.4829 trillion won, and investment earnings climbed 40.5% to 836.2 billion won. Auto insurance moved into cumulative surplus at 39.2 billion won – a meaningful shift for brokers placing fleet and personal motor lines, given that Samsung is one of only two of the five firms to have moved into surplus on that line through nine months.
DB Insurance reported cumulative net profit of 1.312 trillion won, up 9.3%, despite a 13.2% fall in investment earnings. Insurance earnings rose 44.8% to 1.119 trillion won, absorbing the investment shortfall. Hyundai Marine & Fire recorded a 76.2% rise in insurance earnings, lifting net profit 23.1% to 780.8 billion won.
The underwriting recovery across all three firms traces partly to a narrowing gap between projected and actual claims in long-term insurance – the category covering health, disability, and savings-linked products. DB Insurance’s quarterly loss from that gap narrowed to approximately 17 billion won from roughly 150 billion won a year earlier. Hyundai Marine & Fire’s cumulative long-term insurance profit rose 71.8%, according to Seoul Economic Daily.
Meritz Fire & Marine saw cumulative net profit fall 6.8% to 1.3528 trillion won despite a 7.6% rise in insurance earnings. KB Insurance reported a 13.1% gain in insurance earnings, but a 43.2% drop in investment earnings left net profit down 11.2% at 681.1 billion won. Both carriers are moving in the right direction on underwriting, but their overall results are still going backwards – which limits room to hold terms or absorb claims volatility when broker clients push back on pricing.
The divergence sharpened between July and September. At Meritz, insurance earnings rose 34.9% in the third quarter, but investment earnings fell 87.9%, dragging net profit down 29.2%. Hyundai Marine & Fire swung to an investment loss in the same period, cutting quarterly net profit by 9.6%. DB Insurance’s investment earnings fell 55.6% in the quarter, though a 223.7% jump in insurance earnings lifted quarterly net profit 13.4%.
Valuation losses from a stock market correction and rising interest rates were cited as the primary investment headwinds across the group, according to Seoul Economic Daily.

The Financial Supervisory Service (FSS), South Korea’s financial regulator, reported that the auto insurance sector recorded an underwriting loss of 184.8 billion won in the first half of 2026 – its first half-year deficit in six years. The combined ratio, which measures total claims and expense costs as a proportion of premiums earned, reached 101.9% – above the 100% breakeven point at which a carrier pays out more than it takes in. The loss ratio component stood at 84.9% and the expense ratio at 17.0%, according to FSS data published in September 2026 by The Asia Business Daily. All four major carriers posted underwriting losses in the period, with their combined market share at 84.8%.
Accident frequency fell 4.5% in the first half of 2026, yet incurred losses still rose 2.8%, as higher hospital treatment costs and vehicle repair charges pushed up the average payout per claim. The 1.3% premium increase implemented in January 2026 – the first in five years – has not been sufficient to close the gap.
The FSS introduced mandatory medical reviews for minor injury claimants seeking treatment beyond eight weeks following a traffic accident, with the rule taking effect on September 10, 2026. The regulator expects the reform to reduce claims leakage over time.
Within the top five non-life firms, Samsung Fire & Marine and DB Insurance moved to cumulative auto surpluses through nine months. Hyundai Marine & Fire and KB Insurance remained in a loss position.
Carriers flagged higher claims from winter accidents and illness, as well as year-end revisions to loss ratio and lapse rate assumptions, as factors likely to weigh on fourth-quarter results.
“Insurance operations will keep recovering on the back of regulatory improvements and loss ratio management, but without support from investment earnings the rebound in overall net profit will be limited. With year-end settlement adjustments still ahead, gaps between companies could widen depending on how they manage claims payments and how their asset management performs,” an insurance industry official told Seoul Economic Daily, speaking without attribution by name.
The divergence matters for 2027 renewals. Carriers that sustained underwriting discipline without investment income have more room to hold terms. Those that could not face a direct trade-off: absorb the investment shortfall in profitability, or pass it through in pricing and claims management. The Q3 results show which five Korean non-life carriers are on which side of that line.
