How Dealers Use Repo to Fund Treasury Positions and Client Lending
Summary
The document explains that dealers use repurchase agreements to finance Treasury inventories and to support reverse-repo lending to clients. In a repo, a dealer receives cash against securities, while a reverse repo provides cash to a client against collateral. The discussion highlights that dealers’ capacity and willingness to expand these activities are tied to balance-sheet space and access to funding.
The answer notes that funding sources differ: some institutions deploy cash from deposits into repo lending, while others borrow in repo to finance client transactions or other assets. One example describes funding mortgage securities through overnight repo and earning the securities’ higher rate, with the caveat that this carry trade can fail when overnight funding becomes unavailable. The explanation sketches business models rather than detailing accounting, collateral haircuts, counterparty exposure, or liquidity rules, so it is not a complete operational guide to repo financing.
Key ideas
- Dealers may use repo cash to finance Treasury holdings or other assets.
- Reverse repos let dealers lend cash to clients against securities collateral.
- Some institutions lend cash they already hold, while others borrow to finance lending or positions.
- Financing longer-term assets with overnight repo can earn a spread but carries rollover and liquidity risk.

# Banks' use of repo to finance operations # Banks' use of repo to finance operations "Dealers typically use repo to fund both their cash Treasury positions and their lending to clients through Treasury reverse repos. Thus, the ability and willingness to engage in repo, which increases the size of dealers’ balance sheets, will affect their willingness to take on additional inventories and provide lending through reverse repos" extract from below report (Footnote 14, PDF page 43, internal page number 37) https://www.federalreserve.gov/publications/files/financial-stability-report-20201109.pdf From the above, it seems banks raise cash through repos (get cash in exchange for some collateral) to finance treasury holdings and lend the cash clients against treasury securities. I am trying to understand how banks then use the funds raised with repos and got lost: step 1: banks get cash in exchange for collateral step 2: then with this cash they either buy US treasuries (This means they borrow against some collateral(potentially UST) and then buy UST?) or lend this cash to clients against US treasuries (This means they borrow against UST and then lend against UST at a higher rate?) ## Answer by JoshK (score 1) https://quant.stackexchange.com/a/61420 First of all, banks play it both ways. Some banks (JPM especially) are cash-rich and will use their cash (pay depositors 0.00 %) to pick up revenue in the repo markets. Other banks will use the cash from repo to fund other types of repos. For example, in their prime services business they might be able to do a securted loan to clients for LIBOR +50. Banks can also take their morgtage notes and repo those and play the roll down. They get the higher rate of the mortgage and then pay the lower rates of the overnight repo market. This is a great trade until 2008 comes along and overnight cash dissapears.
