## FAQ

### What are U.S. Treasury rates?

Treasury rates are yields on U.S. government debt across maturities from 1 month to 30 years. Constant-maturity yields let you compare the curve on a standardized basis each trading day.

### What is the 10-year Treasury yield?

The 10-year Treasury yield is the benchmark long-term risk-free rate used widely in valuation, mortgages, and macro analysis.

### What does the 2s10s spread mean?

The 2s10s spread is the 10-year yield minus the 2-year yield. A positive (upward-sloping) curve is typical; a negative spread is an inversion often watched as a recession risk signal.

### How often are these rates updated?

Treasury constant-maturity yields are published on business days. LOPJLB caches the latest curve and refreshes it through the market data poller.
