The Median Consumer Solvency Index: The Metric I’m Watching in a Plutonomy
In a plutonomy, the economy does not need the median consumer to be euphoric.
It just needs the median consumer to remain solvent.
That distinction matters.
A large share of discretionary demand can come from affluent households, asset owners, corporations, and high-income professionals. They drive premium housing, luxury travel, expensive restaurants, AI investment, equity market gains, private schools, cultural events, and high-end healthcare.
But the median consumer still has to keep the system from breaking.
The median household needs to keep working, paying rent, servicing auto loans, paying credit cards, buying essentials, and avoiding default.
That is why I think a Median Consumer Solvency Index is useful.
The index would track six things:
- Personal saving rate
- Real consumer spending
- Credit delinquencies
- Labor market strength
- Debt service burden
- Consumer confidence / expectations
Each category gets scored from 0 to 2:
- 2 = healthy
- 1 = strained
- 0 = deteriorating
The maximum score is 12.
My rough interpretation:
- 9–12: Green Zone — consumer is solvent and stable
- 5–8: Yellow Zone — consumer is strained but not broken
- 0–4: Red Zone — consumer stress is becoming systemic
Right now, the key issue is that the consumer may be in the Yellow Zone: strained, rate-sensitive, and increasingly dependent on a still-healthy labor market.
That can coexist with strong equity markets, AI CapEx, luxury demand, premium travel, and high-end housing.
But if the labor market cracks, today’s affordability pressure could quickly become a solvency problem.
That is the plutonomy risk: The top can keep spending. Capital can keep compounding. But the system still needs the median consumer not to break.
