We document regime change in the U.S. Treasury market post-Global Financial Crisis (GFC): dealers switched from a net short to a net long position in the Treasury market. We first derive bounds on Treasury yields that account for dealer balance sheet costs, which we call the net short and net long curves. We show that actual Treasury yields moved from the net short curve pre-GFC to the net long curve post-GFC, consistent with the shift in the dealers' net position. We then use a stylized model to demonstrate that increased bond supply and tightening leverage constraints can explain this change in regime. This regime change in turn helps explain negative swap spreads and the co-movement between swap spreads, dealer positions, yield curve slope, and covered-interest-parity violations, and implies changing effects for a wide range of monetary policy and regulatory policy interventions.
