Methodology proposal
Financial Stress Meter
Current level
Concept only — methodology in development
No score is shown. A level will appear only after the method is defined, tested, sourced, and approved.
Why not just debt-to-GDP?
Countries have carried very different debt ratios with very different outcomes. Pressure depends on what the debt costs, how fast it must be replaced, whether the budget adds more each year, and whether markets are functioning smoothly. So the meter shows each component separately instead of hiding them in one "magic ratio."
Debt-to-GDP: federal debt divided by the size of the economy in a year.Candidate components
No current values are shown. They will appear only after each one is checked against its official source.
| Component | Plain-English meaning | Primary source |
|---|---|---|
| Interest expense vs. federal revenue | How much of each tax dollar goes to interest. | Treasury Monthly Treasury Statement; OMB historical tables |
| Interest-growth relationship | Average interest rate on the debt compared with nominal economic growth. | Treasury average interest rates; BEA GDP |
| Primary budget balance | Revenue minus spending, before interest. A primary deficit means the government spends more than it collects, before paying interest. | CBO budget data; Treasury MTS |
| Debt due for refinancing soon | Share of marketable debt maturing within about a year. | Treasury MSPD |
| Treasury-market funding conditions | How smoothly auctions clear and how easily Treasuries trade (for example, auction tails and bid-to-cover). | TreasuryDirect auction results; Federal Reserve data |
Five proposed levels
No numerical cutoffs have been set. Thresholds will be proposed only after back-testing and published with their rationale.
- 1
Low pressure
Most components point to easy financing and a stable debt path.
- 2
Guarded
One or two components are worsening; others are steady.
- 3
Elevated
Several components are worsening together for a sustained period.
- 4
High pressure
Most components are strained and funding conditions show visible stress.
- 5
Acute pressure
Strain across components plus disorderly Treasury-market functioning.
What would move a level
A level changes only when several components move in the same direction and stay there across more than one data release — not on a single month's reading.
When components disagree
The meter would show each component's own reading next to the overall level and explain the conflict in words, rather than averaging it away.
Testing before any live score
- Back-test against U.S. history and relevant stress episodes in other countries.
- Report where it would have warned, where it would have missed, and where it would have raised a false alarm.
- Publish the formula, component weights, threshold rationale, update frequency, sources, limitations, and revision history alongside the meter.
Revision history: proposal drafted; not yet tested or approved. Back-test results: not yet run.
