We analyze the term structure of Treasury liquidity premium (LP). Through a model
where illiquidity shocks are alleviated by holding Treasuries, we show that LP term
structure is shaped by expectations of future market liquidity, liquidity term premium, and Treasury supply. As predicted, the LP term structure is downward-sloping
in recessions but upward-sloping in booms, and forward LP predicts future LP and
market liquidity. Furthermore, LP is quantitatively important for monetary policy
pass-through: LP dampens the pass-through of interest rate policy yet strengthens
the pass-through of quantitative easings. We also use LP to infer the term structure
of Treasury safety premium.
