You can’t control whether a supplier gets into trouble. You can control how exposed you are when one does. That exposure has a name — supplier concentration risk — and it’s the part of supply-chain risk you can measure today, with no inside information about anyone’s finances.
What it is
Concentration risk is the degree to which your business depends on a small number of suppliers (or a single one) that you couldn’t quickly replace. If one supplier accounts for 30% of your inputs and has no ready substitute, a disruption there isn’t a 30% inconvenience — it can stop the line.
Why it’s the multiplier
Every distress signal — a going-concern flag, a missed payment, a downgrade — only matters to you in proportion to your exposure. The same bankruptcy that’s a footnote for one buyer is an existential event for another, purely because of concentration. That’s why a good supplier-risk view scores the signal against your exposure, not in the abstract.
How to assess it
- List your suppliers by spend, and flag any single-source or hard-to-replace inputs.
- For each critical one, estimate replacement time — days, weeks, or months.
- Cross-reference the critical, hard-to-replace ones against public distress signals.
- Watch that short list continuously — it’s where a failure would actually hurt.
The practical takeaway
You don’t need to monitor every supplier equally. You need to know which few you can’t afford to lose, and watch those closely for the public tells of trouble. Concentration tells you where to point the radar; the distress signals tell you when to act.
