MBS Outperform. Powell Punts. Waiting on CPI Bonds showed slightly more notable signs of life this morning when compared to yesterday, but yesterday was all but dead.  The volatility surrounded Fed Chair Powell's congressional testimony but had more to do with what didn't say as opposed to what he said.  Specifically, he didn't express incremental excitement or expectation about econ data justifying a rate cut any time soon, instead leaving it up to the same old "data dependent" mantra.  Bonds had perhaps been hoping for a bit more dovishness.  Even so, trading levels returned to pre-Powell levels by the close.  10yr Treasuries logged a small increase in yield while MBS improved modestly.  Some of that is driven by the yield curve (shorter maturity Treasuries improved and MBS act more like 5s than 10s these days).  Either way, the focus is even more firmly on Thursday's CPI as far as bond market inspiration is concerned.  Market Movement Recap11:47 AM Modestly weaker overnight with additional losses during Powell testimony.  Mainly an issue for Treasuries.  10yr up 4.4bps at 4.324.  MBS down 2 ticks (.06). 01:26 PM MBS roughly unchanged.  10yr up 3bps at 4.31% 03:32 PM Still sideways with modest MBS outperformance.  10yr up 1.4bps at 4.294.  MBS up 2 ticks (.06).
