The Federal Reserve Bank of New York bought $12bn of mortgage-backed securities (MBS) from mortgage giants Freddie Mac (FRE), Fannie Mae (FNM) and Ginnie Mae in the week ending January 20. Gross purchases totaled $16.36bn — $1.3bn of Freddie MBS and $12.8bn of Fannie MBS — before $2.25bn of MBS sales during the same time frame, according to details released Thursday by the NY Fed. The week brought the Fed's total net purchases to date to nearly $1.15trn. It’s another week of slowed purchases as the Fed winds down its purchase program, which is on track to buy up $1.25trn of agency MBS by the end of Q110. The week's figures bring total net purchases to date to nearly $1.15trn, according to weekly commentary by JP Morgan Securities. At the same time, according to the data, the agency fixed net issuance of MBS totals $423.51bn. The data from JP Morgan indicates the Fed has just over $100bn left to spend under the $1.25trn program. The Fed has considered extending and expanding asset-purchase programs, including the MBS program, if its exit this quarter is not replaced with private investor demand, causing MBS spreads to treasuries to blow out again.
