It's common to see the effects of month/quarter-end trading most prominently in the PM hours and today's quarter-end session was no exception. A glut of bond buying just after 12:30pm got the part started and yields bottomed out just before the 4pm NYSE close. While 4pm is a time that's associated with stocks, it has come to be the larger of the two closing bells for the bond market on month/quarter-end days for a variety of reasons (de-emphasis of CME pit over the years, increased prevalence of ETF trading, large portfolio rebalancing that involves both stock/bond ETFs, thus arguing for one unified closing mark time). From here, econ data should take the wheel although it's always possible to see some new-month positions have an impact on the first day of a new month.

Lock / Float Considerations
Bonds have shifted from range-bound to trending lower in yield this week. Data is only partly able to explain the shift. The rest requires things like friendlier Fed comments and even regulatory changes that allow banks to hold more Treasuries. Either way, weaker data (and the expectation of more to come) is likely part of the equation. That will be very important in the coming days and especially with the jobs report on Thursday. Next week's CPI is critically important as well.
