The Intraday Market Liquidity of Japanese Government Bond Futures Naoshi Tsuchida, Toshiaki Watanabe, and Toshinao Yoshiba We investigate the intraday market liquidity of the Japanese government bond (JGB) futures. First, we overview the movement of various market liquidity indicators during the past decade, classifying them into four cat- egories: tightness, depth, resiliency, and volume. Second, using the data under the current trade time, we extract their intraday pattern and the autocorrelation. Third, we find that the announcement of economic indi- cator has a negative effect on these liquidity indicators while the mone- tary policy announcement and the surprise of economic indicator have a positive effect on volume indicators. Fourth, we show that the shock per- sistence in liquidity indicators rises around April 2013, and the increased persistence remains in some liquidity indicators even several months after April 2013.
