The Federal Reserve today reported on their weekly purchases of agency mortgage-backed securities (MBS). In the five trading days between September 10 and September 16, the Federal Reserve purchased a total of $31.22 billion agency MBS. In those five days the Federal Reserve sold a total of $5.77 billion agency MBS, bringing the weekly net total to $25.45 billion.

The goal of the Federal Reserve's agency MBS program is to provide support to mortgage and housing markets and to foster improved conditions in financial markets more generally. Only fixed-rate agency MBS securities guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae are eligible assets for the program. The program includes, but is not limited to, 30-year, 20-year and 15-year securities of these issuers.

Since the inception of the program the Federal Reserve has spent $861.90 billion, 68.95% of the allocated $1.25 trillion which on pace to run out by the end of 2009.

Of the net $25.45 billion purchases:

  • $4.75 billion was used to buy 30 year 4.5 MBS coupons.  18.66% of total weekly purchases.
  • $8.70 billion was used to buy 30 year 5.0 MBS coupons.  34.18%  of total weekly purchases.
  • $9.55  billion was used to buy 30 year 5.5 MBS coupons. 37.52% of total weekly purchases.
  • $1.15 billion was used to buy 15 year 4.0 MBS coupons.  4.52% of total weekly purchases
  • $1.30 billion was used to buy 15 year 4.5 MBS coupons.  5.11% of total weekly purchases.

Of the $25.45 billion total. 61.7% of the mortgage-backs purchased were Fannie Mae coupons while 24.8% were Freddie Mac, and 13.56% Ginnie Mae.

The Fed's daily purchase average was $5.09 billion per day, an increase from last week's daily average of $4.70 billion per day. The faily purchase average more than doubles the amount of new loan supply sold by mortgage bankers looking to hedge their pipeline from interest rate risk
