Insurance Underwriting Cycle Explained
The recurring pattern in the P&C insurance industry where periods of soft pricing (low premiums, high competition) alternate with hard markets (high premiums, strict underwriting).
What It Means for Investors
The Pattern
Soft Market → Hard Market
| Phase | Characteristics |
|---|---|
| Soft Market | Excess capital, intense competition, prices fall, coverage expands |
| Hard Market | Capital exits, competition decreases, prices rise, coverage tightens |
The 1974-75 Disaster
The letters describe the worst underwriting year in history:
- Combined ratio: 108.3% (industry-wide loss)
- Many insurers failed or left the business
- Only disciplined underwriters survived
Why Cycles Occur
Capital Flows
- High profits attract new capital
- New capital leads to competition
- Competition drives prices below cost
- Losses cause capital to exit
- Remaining capital raises prices
- Cycle repeats
Buffett's Observation
"The insurance business is a tough cycle. You make money when others are leaving the business, and you lose money during the boom."
Key Takeaway
The recurring pattern in the P&C insurance industry where periods of soft pricing (low premiums, high competition) alternate with hard markets (high premiums, strict underwriting).
