## How to read this benchmark

**What a widening or narrowing means.** A widening spread means marketable debt is growing faster. The supply of bonds that trade is expanding relative to the buy-and-hold stock. A narrowing spread means non-marketable programs are growing faster. 

**Why Non-marketable debt as the comparator.** Non-marketable debt is the fixed, held-to-maturity rest of the system. Placing marketable debt against it makes the liquid, traded portion visible. 

**Limitations.** Marketable vs non-marketable debt reflects published Treasury accounting. Revisions can alter historical comparisons. Treat the chart as context for U.S. fiscal conditions, not investment advice. 

## How this benchmark is used

**The traded-float ratio.** The share of marketable debt drives the gross issuance calendar: when marketable debt grows faster, the Treasury must auction more.
