Rates Keep Playing Defense Ahead of Volatile, Holiday-Shortened Week Wednesday's Fed Minutes might have served as an inflection point of sorts for the bond market.  Thursday didn't get too much weaker and trading was very flat.  If today managed modest gains, the takeaway could have been fairly positive.  Instead, bonds continued to weaken today as traders battened down the hatches against a gathering storm of volatility next week.  Between the 3.5 days of trading, CPI data, Treasury auction cycle, and the ECB announcement, that probably makes good enough sense.  At the very least, it's enough to classify today's sell-off as a byproduct of things we can see as opposed to an ill omen about things we can't.
