Most people think insurance is about low premiums and big coverage.

It’s not.

Insurance is a 10-year probability game. And the biggest mistake buyers make?

👉 Looking at one year of data instead of long-term trends.

Because insurers don’t fail suddenly.
They deteriorate slowly—and predictably.

🧠 The 3 Numbers That Decide Your Claim Fate

We keep it simple—but now with a time dimension.

1️⃣ Will They Pay at All? → Incurred Claim Ratio (ICR)

• Ideal range: 70%–90%

• Measures payout discipline

Latest snapshot:

• HDFC ERGO General Insurance → ~84–89%

• ICICI Lombard → ~78–82%

• New India Assurance → ~96–101%

📉 10-Year Trend Insight (ICR)

Private insurers (last decade):

• Gradually moved from ~75% → 80–90% band

• Indicates pricing discipline + data underwriting

Public insurers:

• Drifted from ~85% → 95–105%

• Indicates persistent underwriting stress

👉 Key structural shift:

Private insurers optimize profitability
Public insurers prioritize payout volume

⚠️ What most people miss:

A stable 80–85% over 10 years is far safer than:

• 1 year at 70%

• 1 year at 100%

👉 Consistency > headline number

2️⃣ Will They Pay On Time? → Claim Settlement Ratio (CSR)

• Ideal: 90%+ consistently

Latest snapshot:

• HDFC ERGO General Insurance → ~95–97%

• ICICI Lombard → ~96–98%

• Star Health and Allied Insurance → ~99%

📉 10-Year Trend Insight (CSR)

Industry-wide shift:

• Early 2010s → 80–85% range

• Today → 90–98% range

👉 Why improvement happened:

• digitization

• faster claims processing

• regulatory pressure (IRDAI)

But here’s the catch:

CSR improved across the board—but claim scrutiny also increased

⚠️ Hidden insight:

CSR is improving, but:

• claim approval complexity is rising

• documentation requirements increasing

👉 Faster ≠ easier

3️⃣ Can They Keep Paying? → Combined Ratio

• Ideal: <100%

Real example (trend-driven):

• ICICI Lombard

  • Combined ratio consistently ~102–105% in recent years

📉 10-Year Trend Insight

Private insurers:

• Pre-2015 → 95–100% (healthy)

• Post-2020 → 100–105% (pressure building)

Why deterioration?

• medical inflation

• higher claim frequency

• competitive pricing

Sector-wide structural reality:

Most insurers today lose money on underwriting
and rely on investment income to survive

⚠️ Critical risk:

If markets fall:
👉 underwriting weakness gets exposed immediately

📊 The Big Picture: 10-Year Structural Shift

Then (2015 era)

• Lower claim frequency

• Lower medical inflation

• Combined ratios <100% common

Now (2025–26)

• Medical inflation ~12–15%

• Claim ratios rising across segments

• Combined ratios >100% increasingly common

👉 Insurance has become a margin compression industry

⚠️ A Realistic Failure Scenario

Let’s connect the dots:

• ICR rising from 80% → 100% over decade

• Combined ratio rising from 98% → 105%

• Medical inflation accelerating

What happens next?

• Premium hikes

• stricter underwriting

• delayed approvals

👉 Not a sudden failure—but a slow tightening cycle

🧠 What Smart Buyers Do (Trend-Based Thinking)

Instead of asking:
❌ “Which insurer is best this year?”

Ask:
✔ Is performance stable over 10 years?
✔ Are ratios improving or deteriorating?
✔ Is profitability sustainable without markets?

🎯 Final Takeaway

Insurance failures don’t happen overnight.

They show up in data years in advance.

👉 Rising ICR
👉 Rising combined ratio
👉 Increasing volatility

These are early warning signals.

The real rule:

Don’t buy insurance based on today’s numbers.
Buy based on 10-year behavior.
