Why Jobless Claims Data Moved Markets More Than Normal Weekly jobless claims data is far from irrelevant, but also almost always a forgettable ingredient in the recipe for serious bond market movement.  There are scattered exceptions to that rule and today was a reminder.  Despite a mere 233k vs 240k beat, the bond market reacted the data as if it were one of the 4-5 top tier economic reports that account for the biggest average reactions. In seeking to reconcile that, we can consider the defensiveness priced into the market as a result of last week's labor market data.  With today's claims, we have the 2nd report of the week suggesting the labor market outlook may not be bleak enough to warrant much panic. In addition to all of the above data-related considerations, it has also been a busy week for corporate bond issuance which has added further pressure at times.
