Uneventful Monday as Traders Keep Options Open Bonds traders are keeping options open, both literally and figuratively.  Open interest in Treasury options increased to start the new week, but that's neither a surprise, nor particularly relevant for our purposes.  We're more interested in the relatively flat performance to begin the new week.  Granted, bonds lost a bit of ground versus Friday's latest levels, but managed to retain most of the day's gains.  Today's trading was very flat after the initial pull-back, tacitly suggesting rates are open to suggestions from this week's data and events.  Market Movement Recap09:48 AM Bonds pushing back against overnight weakness at 8:20am CME open.
