Why The Repo Market Will Need The Fed’s Cash Yet Again | Scott Skyrm & Joseph Wang

Episode Summary

Executive Summary: The episode is a deep dive into the repo market with Scott Skirm of Curvature Securities, explaining how repo works, why it matters to cash and leverage, and how regulation changed the market after the GFC. The discussion covers the 2019 repo spike, today’s specialness in Treasury collateral, and how QT could shift funding pressures back into the repo system.

Main Topics: Repo market basics and function (Priority: 5/5): Scott explains repo as short-term secured financing in which securities are borrowed and lent against cash, serving both cash investors seeking safe yield and leveraged traders needing financing. Why repo is structurally important (Priority: 5/5): The market is portrayed as the hidden plumbing of the financial system, especially important for Treasury financing and crisis transmission. Post-GFC regulatory changes (Priority: 5/5): Dodd-Frank and Basel III changed banks’ appetite for repo by imposing leverage and capital constraints, pushing activity away from large banks toward specialist firms like Curvature. September 2019 repo spike (Priority: 5/5): Scott attributes the repo blowout to timing mismatches in cash availability, heavy Treasury supply, and crowded leveraged positioning, which caused overnight rates to surge sharply. Fed balance sheet, RRP, and policy transmission (Priority: 4/5): The conversation explains how the Fed’s reverse repo facility acts as a floor for rates, why it can leak, and how repo/RRP—not just fed funds—transmit policy. Specials versus general collateral (Priority: 5/5): The episode distinguishes ordinary GC repo from “specials,” where scarce on-the-run Treasuries trade at very low or negative repo rates because of high short demand. QT and future repo market stress (Priority: 5/5): Scott predicts balance-sheet runoff and Treasury issuance will drain the RRP first, then push repo rates higher and eventually drive renewed use of the Fed’s repo facility.

Key Arguments: Repo is a collateralized, short-term funding market that underpins both safe cash investment and leverage for speculative positions. The repo market grew alongside Treasury issuance, but post-crisis regulation made banks more balance-sheet constrained and reduced their repo intermediation. The 2019 repo spike was driven by a temporary shortage of cash during the morning funding window, amplified by large Treasury supply and crowded leveraged trades. The Fed’s reverse repo facility sets an administered floor, but market rates can still trade below it because not all participants can access the facility and banks/money funds compete for business. “Special” repo rates can become deeply negative when a particular on-the-run Treasury is scarce and heavily shorted, reflecting demand for that exact security rather than broad cash conditions. QT and continued fiscal deficits will likely exhaust excess cash in the RRP and force higher repo rates, with the Fed’s repo facility acting as the backstop source of funding.

Data Points: Repo market size: $3 trillion to $4 trillion - Joseph cites latest Fed data to emphasize the scale of the market. Fed balance sheet in 2019: About $3.6 trillion - Level before the balance sheet expanded under QE. Fed balance sheet now: About $9 trillion - Used to show how much securities moved off the market and onto the Fed’s balance sheet. Fed balance sheet growth: About $5 trillion - Approximate increase from 2019 to the present during QE. Repo spike rate in Sept. 2019: Around 7% to 9% - Scott describes overnight repo rates surging during the 2019 funding squeeze. RRP rate: 30 basis points - Administered reverse repo rate used by the Fed as a floor for money market rates. Earlier RRP rate: 5 basis points - Referenced as the prior setting before the March hike. Fed funds target range: 25 to 50 basis points - Current policy range referenced throughout the discussion. Overnight repo rate recently: As low as -140 basis points - Example of a Treasury special rate for the on-the-run two-year note. RRP balance: About $1.8 trillion - Amount of cash currently parked in the Fed’s reverse repo facility. QT runoff pace: 90 to 95 billion per month - Scott’s estimate of securities rolling off the Fed balance sheet. Treasury deficit issuance: About $100 billion per month - Ballpark estimate used to describe net new Treasury supply. 1990s market structure: Bank-oriented and highly competitive - Used to contrast the pre- and post-GFC repo market structure.

Pivotal Quotes: "the repo market is what greases the engine" — Scott Skirm: Scott explains the market’s role as the hidden but essential financing layer of the financial system. "It’s a leaky floor" — Joseph Wang: Joseph describes how the Fed’s reverse repo facility does not perfectly prevent market rates from trading below the administered rate. "This is what’s gonna happen" — Scott Skirm: Scott introduces his forecast that QT, Treasury issuance, and draining RRP balances will push repo rates higher and increase Fed facility usage.

Implications: Listeners should expect repo funding conditions to tighten as QT, Treasury issuance, and collateral scarcity reshape short-term rates. The market may move from excess cash in RRP toward higher repo rates and greater reliance on the Fed backstop.
