Dueling Fed comments and conflicting anecdotes about the jobs market are dovish one minute, hawkish the next.

That's what influenced the last day's activity in the bond market, and yields have moved higher, lower and higher in response. The market is so tethered to Fed policy that it has become a mirror of Wall Street's uncertainty about when the central bank will raise interest rates. This week it is especially on edge, reflecting anxiety ahead of Friday's monthly jobs report, one of the most important pieces of data the Fed will review before its September rate decision.
