I find that short-maturity Treasury-bill yields have unique information about risk premiums that is not spanned by long-maturity Treasury-bond yields. I estimate 2 components of risk premiums: long term and short term. The long-term component steepens the slope of yield curves and has a forecastability horizon of longer than 1 year. In contrast, the short-term component affects Treasury-bill yields but is almost invisible from Treasury bonds, has a forecastability horizon of less than 1 quarter, and is related to bond liquidity premiums.
