Quite simply, markets are waiting for the last 3 days of this week before gleaning any "takeaways" about the current state of financial markets, the economy, inflation, or Fed policy.  Everything over the 1st 2 days of the week has therefore amounted to a pre-game show--and not a very exciting one at that.  

For the most part, bond yields have held inside the same trading range seen since last Thursday morning, although they did begin to test a break lower after today's 3pm close.  Officially, however, yields closed above the 2.362% floor that's been intact for 4 days now.  

With market participants fully aware of the absence of actionable calendar items on the first 2 day of the week, it hasn't been too surprising to see lighting trading conditions in terms of volume and volatility.  The side effect of the light volume and lack of inspiration is that some headlines will end up moving markets more than they otherwise would in the presence of more robust volume. 

Today's Trump Jr. Twitter news was just such an example.  It prompted a "risk-off" move for bonds.  10yr yields moved into positive territory shortly thereafter, but just barely.  Comments from Fed's Brainard didn't hurt the move, which saw yields hit their best levels just before 1pm.
