Treasuries weakened across the yield curve Tuesday as bond investors expressed their nervous sentiments over a few increasingly vocal inflation hawks on the FOMC board.

The Fed's overnight lending rate has been at an unprecedentedly low zero to 0.25% range since December 2008. Some members of the FOMC are calling for those rates to rise as its program of quantitative easing is scheduled to conclude this summer. Rising rates would mean that current Treasury coupons are less attractive, which causes a sell-off.  Just last night St. Louis Federal Reserve chief James Bullard said that it was unlikely that for the Fed would wait for unemployment to reach normal levels before removing monetary accommodation.

Yield spreads tightened in the morning hours and widened out into the close, ending the two-day period essentially unchanged vs. the curve. Reprices for the worse were reported.

The just released MBA Mortgage Index showed applications fell 2% in the week ending April 1.

Refinancings declined 6.2% percent to its lowest level since February 25, while purchases increased 6.7% to its highest level of the year. A good deal of the latter, however, was due to government purchases stepping up 10.3% to its highest level since May 7, 2010.

"Purchase application volume increased last week reaching the highest level of the year, but remains relatively low by historical standards, at levels last seen in 1997," said Michael Fratantoni from MBA. 

"The increase last week was due to a sharp increase in applications for government loans. Borrowers were likely motivated to apply before a scheduled increase in FHA insurance premiums that became effective last Friday." he added. "Rates were flat last week, but refinance activity fell, as the pool of borrowers who have both the incentive and the ability to qualify for a refinance continues to shrink."
