Follow the Cash: Why Repo Markets Are a Patchwork of Structures
Gara Afonso, Jun-Davinci Choi, Gonzalo Cisternas, and Will Riordan · September 29, 2026
The U.S. repo market isn't one market — it's several, each with its own participants, settlement habits, and clearing arrangements. Economists at the New York Fed trace how cash actually moves through these segments to explain why the plumbing looks the way it does.
The puzzle: large cash lenders, such as money market funds, usually route trades through a third-party agent rather than dealing directly. Interdealer trades, by contrast, clear through a central counterparty. And leveraged investors — hedge funds seeking short-term funding for bond positions — tend to prefer bilateral trades struck directly with a dealer.
Each choice reflects a trade-off between cost and risk. Agency settlement buys operational convenience and reduced counterparty exposure, but adds a layer of fees. Central clearing mutualizes default risk among dealers, which supports liquidity in the busiest segment. Bilateral repo is flexible and fast, letting levered players adjust positions quickly, but it concentrates credit risk on the dealer's balance sheet.
Why it matters: repo is the collateralized funding backbone of the Treasury market and a key channel for monetary policy. Understanding who bears risk, and where, helps investors judge how resilient funding markets are under stress — and why episodes of repo-rate spikes can flare up in specific segments rather than the market as a whole.
