It feels virtuous every so often to take glance over at the triparty repo market. You get a nice dose of horrified vertigo and then go back to your life and don’t think about it for a while and that always feels better. Now is a good time to get back to it, what with continued worrying about money-market funds – a core player in the market – and two interesting things this week about triparty repo: this testimony from Matthew Eichner of the Fed to a Senate subcommittee, and this report from Fitch.
Here is how I imagine triparty repo:
- A bunch of money market funds and other cash investors keep $1.8 billion of cash at JPMorgan and Bank of New York Mellon, the “clearing banks” in the triparty system.
- A bunch of securities dealers keep a pile of securities – worth, on a good day, more than $1.8bn – to JPM and BoNY Mellon.
- The dealers need money to fund those securities, because what are they going to do, pay for them themselves?
- Every afternoon, the cash investors and the securities dealers frantically negotiate which dealers swap their securities (at negotiated haircuts) for which cash investors’ cash.
- Every night, the cash sleeps in the (notional) arms of the securities dealers, while the securities (and a promise to buy them back in the morning) sleep in the (notional) arms of the cash investors.
- Every morning, the cash wakes up and springs from the dealers’ beds back into the waiting arms of the cash investors, and vice versa etc.
- Which means that the dealers need to borrow cash to be able to give it back to the investors. Where do they get the money?
- Well, from JPMorgan or BoNY.
- Where do JPM and BoNY get the money?
- Well, from deposits.
- Whose deposits?
- Well, the deposits of the cash investors.
