A Treasury bill is a short-term US government debt security maturing in under one year and generally treated as having negligible default risk. It belongs to the fixed-income family: investors lend money and receive principal at maturity, with payment terms varying by instrument. section 5.2 section 5.5
Treasury bills provide a reference point for comparing income investments. Interest-rate policy affects bond prices and yields: higher rates make newly issued debt more attractive and can reduce the appeal of existing lower-yield securities. section 5.2
Rate-data workflow
A Python workflow can retrieve US Treasury bond data through EODHD, load it into a pandas DataFrame, and plot prices or yields to compare changing fixed-income conditions. The example concerns Treasury bond data broadly rather than a bill-specific valuation. section 5.2
