Today's only relevant economic data is the Producer Price Index (PPI)--an inflation metric at the wholesale level.  Although inflation is back in the spotlight after years of obscurity (it was so far from a consideration that smart investors didn't care about inflation reports), some inflation data matters more than others.  

If there's a lead dog, it's the Consumer Price Index (CPI), which has consistently been a bigger market mover than PPI.  In the following chart, note how much bigger the movement has been on CPI days--especially those in May and June which were among the biggest trading days of the summer.  In fact, if one piece of economic data is responsible for bond market resilience during those months, it's CPI.

If anything will garner a meaningful reaction today, it would be the afternoon bond trading environment following the week's final Treasury auction.  Despite the bigger movement this week, volumes have been exceptionally low (especially relative to the movement) and the amount of new debt issuance (both Treasuries and Corporate Bonds).  In that environment, there's a better chance of seeing a market reaction to a simple thing like the shift in supply/demand dynamics that can follow the week's final Treasury auction.
