【内容摘要】
Primary dealers intermediate Treasuries by holding bonds directly or by financing through repo. Before the financial crisis the two channels moved in opposite directions.

A preferred-habitat model with shocks to dealers’ repo capacity accounts for all three facts. Arbitrageur risk aversion cannot replace the repo-capacity shock: it pushes pre-crisis co-movement in the wrong direction, and it cannot explain stress episodes in which term premia fell.
