Price Formation and Liquidity in the U.S. Treasury Market: The Response to Public Information
21 Pages Posted: 9 Mar 1999
The arrival of public information in the U.S. Treasury market sets off a two-stage adjustment process for prices, trading volume, and bid-ask spreads. In a brief first stage, the release of a major macroeconomic announcement induces a sharp and nearly instantaneous price change with a reduction in trading volume, demonstrating that price reactions to public information do not require trading. The bid-ask spread widens dramatically at announcement, evidently driven by inventory control concerns. In a prolonged second stage, trading volume surges, price volatility persists, and bid-ask spreads remain moderately wide as investors trade to reconcile residual differences in their private views.
