How Repo Direction Depends on the Cash Borrower and Lender

Summary

The document clarifies repo terminology by focusing on the transaction’s cash flow and economic purpose. A party that sells securities while agreeing to buy them back is raising cash against those securities, or economically lending securities, and is on the bid side of the repo market. A party that provides cash in exchange for securities and agrees to sell them back is lending cash and looks to the offer side.

This framing explains why a portfolio manager might describe a transaction as reversing securities out: the manager is borrowing money using securities as collateral, an arrangement economically similar to securities lending. The terms repo and reverse repo can sound inconsistent when viewed only from one participant’s perspective, so identifying which party supplies cash and which receives securities resolves the ambiguity. The explanation is brief and does not cover operational conventions, collateral haircuts, term structure, or how naming conventions can vary across institutions and markets.

Key ideas

• A repo transaction can be understood by identifying which party provides cash and which provides securities.
• Selling securities and agreeing to repurchase them raises cash and is economically similar to lending securities.
• Buying securities with cash and agreeing to resell them is a cash-lending transaction.
• The labels repo and reverse repo depend on the participant’s perspective and can be confusing without tracing the cash flows.

# Question about 'reversing in' in repo markets


# Question about 'reversing in' in repo markets












In Stigum's money market book, in the chapter on repo, he talks about 'reversing in a security'. Then later on he quotes a portfolio manager sayin 'I reverse out securities to dealers, but I never refer to it around the company as 'lending out' our valuable securities.' I feel like there is an abuse of language here, but I am confused. A reverse repo is (typically) when cash leaves and a security comes in. Here, is he using reverse in a lose way where, I reverse XXXX (could be cash or securities) when it leaves my balance sheet? So a security reverse is the same as a traditional repo? Not sure if this is the right place to ask this, I know it is not a 'quantitative' question.

So the "reverse repo" market has a bid-offer expressed in rates. If you are selling securities and agreeing to buy them back, you are borrowing cash (or lending securities) and are looking at the bid side. Conversely, if you are looking to lend cash, you will be buying securities and agreeing to sell them back and looking on the offer side. In your example, your PM is looking to borrow money, using his securities as collateral for his loan. This is very similar to a securities lending transaction, hence his comment regarding "lending out" valuable securities.
