The following frequently asked questions (FAQs) provide further information about the Federal Reserve's reinvestment of principal payments from its holdings of agency debt and agency mortgage-backed securities (MBS) in agency MBS.
Effective September 20, 2017
How is the Desk implementing the FOMC’s directive for agency MBS  reinvestment purchases?
  In its September 20, 2017 statement, the Federal Open Market Committee (FOMC)  announced that it will initiate, in October, the balance sheet normalization  program described in the June  2017 addendum to the Committee’s Policy Normalization Principles and Plans. This  program will gradually and predictably reduce the Federal Reserve’s securities  holdings by decreasing the reinvestment of principal payments from securities  held in the System Open Market Account (SOMA). Specifically, the FOMC has  directed the Open  Market Trading Desk (the Desk) at the Federal Reserve Bank of New York  to reinvest the principal payments from the Federal Reserve’s  holdings of agency debt and agency MBS received during each calendar month that  exceed the cap amount for that month. If the anticipated amount of principal  payments is lower than the cap in effect that month, then the Desk will not  reinvest those principal payments. In October 2017, the monthly cap will  be $4 billion, and based on the June 2017 addendum, the cap will increase in  steps of $4 billion at three-month intervals over 12 months until it reaches  $20 billion per month. For the schedule of monthly caps, see: https://www.newyorkfed.org/markets/opolicy/operating_policy_170920.
  How will the Desk determine the amount of funds to reinvest each  month and how will this be communicated?
  The Desk will  calculate the agency MBS reinvestment amount by subtracting the monthly cap  from the amount of principal payments from agency debt and anticipated amount  from agency MBS to be received during a calendar month. On or around the ninth business  day of each month, after receiving information from the agencies on expected  principal payments, the Desk will publish the amount of agency MBS purchases  expected to take place between the middle of the current month and the middle  of the following month (see https://www.newyorkfed.org/markets/ambs/ambs_schedule.html).  The announced purchase amount is subject to change should the FOMC alter its  directive to the Desk during the month or if market conditions warrant.
As an example, consider the situation where a given month’s cap is $4 billion and that the principal payments to be received from agency debt are $2 billion and the anticipated principal payments to be received from agency MBS are $18 billion. To determine the amount of reinvestment purchases of agency MBS, the Desk will subtract the $4 billion cap from the total principal payments of $20 billion ($2 billion from agency debt and $18 billion anticipated from agency MBS). An announcement will be made on or around the ninth business day of that month indicating that the Desk will purchase $16 billion of agency MBS, with operations starting on the following business day and running through the ninth business day of the following month.
The reinvestment amount reflects the principal payments anticipated to be received that month; however, actual principal payments received may deviate slightly from the anticipated amount. In addition, the actual reinvestment purchases may deviate slightly from the stated purchase amount due to operational reasons. The Desk will not make adjustments for these deviations in future months’ purchases.
  What types of agency MBS will the Desk purchase?
  Agency MBS purchases will likely be concentrated in fixed-rate 30-year and  15-year agency MBS in the To-Be-Announced (TBA) market. The Desk may purchase  other agency MBS if market conditions warrant. Only agency MBS securities  guaranteed by Fannie Mae, Freddie Mac and Ginnie Mae are eligible for purchase. 
  Is there a minimum amount required for conducting agency MBS  reinvestments? 
  Yes. The Desk’s monthly reinvestments in agency MBS will be subject to a $1 million minimum threshold due to technical requirements.
Will the Desk sell agency MBS if the monthly cap exceeds monthly  principal payments from agency debt and agency MBS?
  No. The cap is the maximum amount that the SOMA holdings of agency debt and agency MBS will  decline each month. If the total amount of monthly principal payments  from agency debt and agency MBS is below the monthly cap amount, then the  reduction in the SOMA’s agency debt and agency MBS holdings that month would be  equal to the amount of principal payments, and no agency MBS reinvestments will  occur. 
  How will agency MBS  purchases be conducted?
  The Desk  will conduct purchases of agency MBS via FedTrade, the Desk’s proprietary  trading system. FedTrade operations will be conducted using multiple-price,  competitive auctions with approved counterparties. A "multiple-price"  auction is an auction in which the same security can be awarded at different  prices, with awards given to participants at a price corresponding with an  individual offer submitted to the operation. The minimum auction amount, offer  size, and offer increment are each $1 million. Participants can submit up to  ten offers per security, with each offer reflecting a price and par amount.  Offers in FedTrade operations will be evaluated based on their proximity to  prevailing market prices at the auction close.
  How will the tentative schedule of FedTrade operations be  communicated?
  The Desk will publish a tentative schedule of FedTrade agency MBS  operations twice a month, each covering a period of approximately two weeks.  The first schedule will be released on or around the ninth business day of the  month. The second schedule will be published on or around the nineteenth business  day of the month and will run until the next purchase schedule is released.
The tentative schedule will include information on the upcoming operation dates, times, security types (agency and coupon) and maximum purchase amount per security. The schedule reflects reinvestment policy decisions that have been announced by the FOMC, and is subject to change. No inference should be drawn about possible future adjustments to the stance of monetary policy from the schedule.
  How often will purchases take place?
  Purchases will be conducted on a regular basis over the course of each monthly  period, with the timing guided in part by general agency MBS market conditions,  including, but not limited to, supply and demand, market liquidity, and market  volatility. The Desk may adjust the size and frequency of agency MBS purchase  operations as the monthly reinvestment amount declines. 
  Will the Federal Reserve conduct agency MBS dollar rolls or  coupon swaps?
  The Desk may use dollar roll and coupon swap transactions if needed to  facilitate settlement associated with its unsettled agency MBS purchases. A  dollar roll is a transaction that generally involves the sale of agency MBS for  delivery in one month with the simultaneous agreement to purchase agency MBS,  with the same agency, tenor and coupon, for delivery in a different month. A  coupon swap is a transaction that involves the sale of one agency MBS and the  simultaneous purchase of another agency MBS, each with different agencies, coupons,  and/or tenors.
The Desk would conduct dollar roll and coupon swap transactions via Tradeweb, a commercial trading platform. Transactions conducted over Tradeweb would be executed through a competitive bidding process in line with standard market practices.
  Under what circumstances may the Federal Reserve conduct agency  MBS dollar rolls?
  Based on the directive from the FOMC, the Desk may conduct dollar rolls in  order to facilitate settlement associated with its unsettled agency MBS  purchases. Selling dollar rolls effectively postpones the settlement of  outstanding forward purchase commitments, while buying dollar rolls effectively  brings settlement forward. Dollar rolls would typically be conducted only if  implied financing rates on agency MBS are notably below or above the general  level of short-term interest rates, as such conditions may signal a shortage or  abundance of supply, respectively, available for settlement. The Desk may  conduct dollar rolls throughout the month, but at least two business days  before TBA settlement dates. The amount of dollar rolls conducted may vary  throughout the month depending on movements in implied financing rates.
  Under what circumstances may the Federal Reserve conduct agency  MBS coupon swaps?
  Based on the directive from the FOMC, the Desk may conduct coupon swaps in  order to facilitate settlement associated with its unsettled agency MBS  purchases. However, the Desk does not anticipate conducting such transactions  unless market conditions suggest that purchases are unlikely to be settled for  quite some time, as suggested by dollar-roll implied financing rates that are persistently  below the general level of short-term interest rates, prolonged fails, or other  market functioning indicators. 
  Would agency MBS dollar roll or coupon swap transactions reduce  the amount of total outright agency MBS purchases?
  No. Dollar roll and coupon swap transactions are the simultaneous sale and  purchase of the same face amount of agency MBS. Thus, they only affect the  timing or composition of the settlement of the Federal Reserve's agency MBS  purchases.
How will the Desk communicate the FedTrade operation results?
Operation results from FedTrade will be posted on the New York Fed’s  website following each operation. The information posted will include the total  amount of propositions received per auction, the total amount of propositions  accepted per auction, the total amount accepted per security, and the settlement  month. In addition, participating dealers will receive the operation results,  including their accepted propositions, via FedTrade, immediately following the  close of the auction.
  How will the Desk communicate agency MBS transaction  details? 
  The New York Fed publishes SOMA agency MBS transaction activity on its  website on a weekly basis. Activity data includes the total amount of weekly  purchases and dollar roll transactions by agency, coupon, maturity and  settlement month. This information will include transactions conducted over  FedTrade and Tradeweb.
  How are the Federal Reserve's holdings of agency MBS reported?
  Agency MBS transactions are reported after settlement occurs on the H.4.1.  statistical release titled "Factors Affecting  Reserve Balances of Depository Institutions and Condition Statement of Federal  Reserve Banks." This report also includes information on total  outstanding commitments to buy and sell MBS in Table 3 entitled  "Supplemental Information on Mortgage-Backed Securities." Trade  settlements may occur well after trade execution due to agency MBS settlement  conventions. The New York Fed also publishes on a weekly basis detailed data on  all settled SOMA agency MBS holdings. Any change in the composition of these  reported holdings over time is a function of principal payments, outright  purchases, CUSIP aggregation, dollar roll, and coupon swap activity.
  Will the Desk release operation pricing results?
  
  Yes. In order to ensure the transparency of its agency MBS transactions, the  Desk, at mid-month for the prior monthly period, will continue to publish  historical operation results. This information will include the transaction  prices in individual operations. In addition to the pricing information  released each month, Section 1103 of the Dodd-Frank Wall Street Reform and  Consumer Protection Act of 2010 requires that detailed operational results,  including counterparty names, be released two years after each quarterly  transaction period.
Who is eligible to transact in agency MBS with the Federal  Reserve?
The New York Fed's approved counterparties are eligible to transact in agency  MBS directly with the Federal Reserve. Approved counterparties are expected to  submit bids or offers for themselves and for their customers.
Whom should dealers call if they experience difficulties during  a FedTrade operation?
Approved counterparties may call the New York Fed’s Trading Desk with  submission and verification questions. For FedTrade system-related problems,  dealers may call the New York Fed’s Primary Dealer Support line.
Does the Federal Reserve assess the TMPG agency MBS fails  charge?
Yes. Effective February 1, 2012, the failure of the Federal Reserve's  counterparties to deliver agency MBS for the contractual settlement date of the  Desk's trades has resulted in the Federal Reserve assessing the applicable  agency MBS fails charge recommended by the Treasury Market Practices Group  (TMPG). Additional information can be found at https://www.newyorkfed.org/tmpg/index.html
Does the Federal Reserve require the posting of margin for  unsettled agency MBS trades?
Yes. The Federal Reserve requires counterparties to post margin to the New York  Fed. Margin is calculated on a daily basis and serves to protect the New York  Fed from counterparty credit risk exposure arising from the unsettled agency  MBS TBA trades.
What  is CUSIP Aggregation?
CUSIP aggregation is a process through which a number of existing MBS issued or  guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae with similar  characteristics, including uniform agency backing, coupon, and original term to  maturity, are consolidated into a larger pass-through security. The aggregated  CUSIPs are similar to those agency MBS being consolidated, except that the  aggregated CUSIP represent groups of agency MBS, which themselves represent  groups of residential mortgages that conform to specified requirements. The  cash flows from the underlying agency MBS provide the cash flows for the  aggregated CUSIP. Additional information about CUSIP Aggregation can be found  on the Agency  MBS CUSIP Aggregation FAQ page.
