How Repo Operations and Cash Flows Affect Short-Term Funding Rates
Summary
The document collects introductory questions about repo markets and Federal Reserve operations. It asks how open market activity and overnight or term operations affect funding, whether these actions amount to purchases of Treasury debt, how hedge funds participate in overnight funding, and how reserve levels relate to repo rates. It also asks why corporate tax dates may affect repo conditions.
The answer directs readers to Federal Reserve Bank of New York material for explanations of the operations. It offers one concrete mechanism for tax dates: corporate treasurers may hold cash through money market funds, then withdraw it to make payments. Those withdrawals can lead funds to sell Treasury bills or commercial paper, putting upward pressure on rates, all else equal. This is a brief introductory response, not a full account of repo plumbing or an assessment of the scale or persistence of such effects. It does not resolve the other questions about reserves, counterparties, operation design, or taxpayer exposure.
Key ideas
- Federal Reserve Bank of New York materials are suggested for understanding market operations.
- Corporate tax payments can prompt withdrawals from money market funds.
- Fund withdrawals may lead to bill or commercial paper sales and put upward pressure on rates, all else equal.
- The response gives a possible cash-flow mechanism but does not explain repo operations comprehensively.
- Questions about reserves, hedge funds, and the scale of Federal Reserve support remain unanswered.

# Repo- A few questions # Repo- A few questions A few questions which could be related to each other, to help me gain familiarity with repo. These are accompanied with my guess. If anyone can explain in layman's terms (this is new to me). 1) I read on Risk.net The FED now bails out the repo market every day. Can anyone explain what this means, in what form is this done? To what extent is this sustainable? Can this hurt the tax-payer? Is this a matter of buying (back) US debt from the market? 2) I do not understand the jargon The FED pumps money in the market. How is this concretely done? Is this overnight FED purchase of US debt? 3) What is the role of the FED's open market trading desk? Is this to meet the FED's target rate? I though the FED only hiked/cut rate one FED meeting dates (not on a daily basis). 4) What are the FED's term operations, and the FED's overnight operations? The later is, I guess, US Treasuries purchase by the FED? 5) What is overnight funding? My understanding is that hedge funds are key players, in what manner? 6) What is the link between corporate tax payments and the repo market? Is it the case that Corporates presumably need cash on tax dates (to pay tax) and that drives the repo rate higher? And only for one single day (4 times a year)? 7) What is the link between excess reserves and the repo market? What is the incentive for high excess reserves? This presumably creates cash scarcity prompting a higher repo rate? ## Answer by user42108 (score 1) https://quant.stackexchange.com/a/49563 FRB NY website would be a good place to start answering those questions given they implement the bailouts/money pumping/OMOs + TOMOs. As to 6), corporate treasurers invest cash in the money market via money market funds (MMFs). When that cash is needed, e.g. for a tax payment, they will withdraw money from the MMFs which, all else equal, will put upward pressure on rates as they sell bills or commercial paper.
