What Moves the Bond Market? Fleming and Remolona
Introduction • The goal is to identify the factors that may explain large price changes and large surges in trading activity in the bond market. • To that end, the authors instrument statistical exercises to determine the association between bond market movements and announcements of economic indicators.
Structure of the Document • Anecdotal Evidence • Correlation of price changes and trading surges with release times of macroeconomic conditions. • Formal Analysis • Econometric exercise to evaluate the impact of: • Type of announcement • Magnitude of the surprise element • Market conditions
Methodology and Data • The bond market is represented with the five-year U.S. Treasury note. • High-frequency intraday data for bond market activity is employed. • Dates and release times for 21 economic indicators. • The sample period is from August 23, 1993 to August 19, 1994.
Econometric Analysis • Run a regression • Dependent variables: • Price volatility as measured by the percentage change in the five minute interval following an announcement. • Trading activity: number of transactions during the one-hour interval following the announcement. • Independent variables: • Announcement dummy variables.
Announcement Surprises • Add to the regression a variable to measure the surprise component of announcements:
Market Conditions • Introduce two measures of uncertainty: • Volatility derived from options on then-year U.S. Treasury notes. • Expected change in the fed funds rate.
Conclusions • Each of the 25 sharpest price changes and greatest trading surges are associated with a just-released announcement. • The largest responses are correlated, in order of importance, with the employment report, producer price index, federal funds target rate, and the consumer price index. • Bond market activity responds significantly to the “surprise” component of announcements and market conditions.
