Supply Contraction and Trading Protocol: An Examination of Recent Changes in the U.S. Treasury Market
研究美国国债市场供给收缩期间流动性和交易者行为的变化，发现交易商在供给收缩时更少发现深度信息，而通过GovPX报告的声音经纪交易仍对深度发现重要。
We investigate liquidity and trader behavior in the U.S. Treasury market during recent supply contractions. As in the precontraction period, dealers employ expandable order strategies to achieve greater-than-posted depth at the posted price and use expandable orders more often when expected information asymmetry is greater. Overall, however, dealers are less likely to discover greater-than-quoted depth during the supply contraction regimes. We find that, even after substantial losses in their market share of coupon Treasury trading, brokers reporting voice-brokered trading through GovPX provide an important protocol for depth discovery.We investigate liquidity and trader behavior in the U.S. Treasury market during recent supply contractions.
