Lots of Competing Motivations Causing Volatility In a Narrow Range Today marked an uptick in the importance of economic data for the week and it had obvious consequences for volatility.  Of particular importance was the higher reading in quarterly PCE prices.  Because this is the first look at Q2 data, it's one of 4 days each year where the PCE component of the GDP data offers a sneak peek at the full PCE report that comes out the following morning.  the 2.9 vs 2.7 reading suggests there's extra inflation that will be distributed between April, May, and June.  If June accounts for more than the other two months, tomorrow's PCE index will be higher than expected, and thus bad for rates.  That accounts for some weakness this morning, but traders are also in the midst of adjusting their yield curve positioning which has resulted in big discrepancies between longer and shorter term rates this week.
