According to the NY Fed website:
In accordance with the most recent Federal Open Market Committee (FOMC) directive, the Open Market Trading Desk (the Desk) at the Federal Reserve Bank of New York will conduct a series of overnight and term repurchase agreement (repo) operations to help maintain the federal funds rate within the target range.
Effective the week of October 7, the Desk will offer term repos through the end of October as indicated in the schedule below. The Desk will continue to offer daily overnight repos for an aggregate amount of at least $75 billion each through Monday, November 4, 2019.
Securities eligible as collateral include Treasury, agency debt, and agency mortgage-backed securities. Awarded amounts may be less than the amount offered, depending on the total quantity of eligible propositions submitted. Additional details about the operations will be released each afternoon for the following day’s operation(s) on the Repurchase Agreement Operational Details webpage. The operation schedule and parameters are subject to change if market conditions warrant or should the FOMC alter its guidance to the Desk.
What is the difference between overnight and term operations? Also, how are these operations are done exactly?
This is coming from the point of view where the media is chattering that the Feds are "injecting" money to the repo market. So I am trying to warp my thoughts around it.
