Price formation and liquidity in the U.S. Treasury market: evidence from intraday patterns around announcements

No 27, Staff Reports from Federal Reserve Bank of New York

Abstract: We identify striking adjustment patterns for price volatility, trading volume, and bid-ask spreads in the U.S. Treasury market when public information arrives. Using newly available high-frequency data, we find a notable lack of trading volume upon a major announcement when prices are most volatile. The bid-ask spread widens dramatically with price volatility and narrows just as dramatically with trading volume. Trading volume surges only after an appreciable lag following the announcement. High levels of price volatility and trading volume then persist, with volume persisting somewhat longer.
