Bond markets opened stronger in very early morning trading but are losing some of their steam.  There is no economic data on the calendar today.  The market could get volatile midday after the results of the US Treasury's 3-year note auction are announced.  Also, today the minutes from the last Fed FOMC (Federal Open Market Committee) meeting will be announced.  There is increasing speculation that the Fed will begin laying the groundwork for rate increases.  Investors will be looking at the minutes carefully for any hints.
