With the shutdown ongoing, and the big ticket econ data vanished into the void, there's little for the bond market to do apart from get its books in order for month-end.  If you're curious about some of the month-end trading considerations that can impact bonds, we have a primer. Month-end can involve either buying or selling (or both).  Timing can vary, but the more visible impacts tend to show up between 8-10am and/or around the 3pm CME close or 4pm NYSE close.  So far today, this morning's strength has some month-end flavor with apparent asset-allocation trading (bond yields and stock prices moving in same direction) starting at the 8:20am CME open.  End of day volatility is a possibility, but not a guarantee.  Either way, as hoped, the market got this week's post-Fed trading out of the way by yesterday mid-day.
