No one really knows how big the U.S. repo market is. Or rather, no one đť‘‘đť‘–đť‘‘. We combed through the appendixes to a decade of annual reports for over 150 dealers and banks to get the full picture. The total? $12 trillion, almost doubling previous estimates.

Getting the full picture on repo exposures is key. Without gross data, matched book intermediation looks smaller than it is, and net funding appears larger, overstating dealers’ use of repo to finance their own positions.

Matched book intermediation is sometimes attributed to post-crisis regulations like the SLR, which incentivizes netting repo activity against reverse repo. But we find no significant difference in matched book use between dealers subject to the SLR and those that aren't.

One striking finding: most dealers in repo are just passing flows through. Matched books, where cash moves from MMFs to hedge funds, drive most of the variation in repo activity. Growing repo volumes are funding strategies like the basis trade, not dealer inventories.

Why it matters:. Repo is the backbone of Treasury market functioning, hedge fund leverage, and monetary policy transmission. But even basic facts, like the total size of the market, haven’t had clear answers. This note helps fill that gap.

Most public figures rely on net exposures or focus only on certain banks or markets. We build up a gross estimate using:.• FOCUS annual reports.• Holding company 10-Ks.• Transaction-level data from cleared and tri-party repo. That helps capture the full scale of activity.

We've put out an update to our 2021 paper, now titled "Hedge funds and the Treasury cash-futures basis trade," for a resubmission. Want to know what drove the increase in basis trade volumes prior to March 2020? We've got you covered. A couple details below 👇

The ECB puts EGB gross futures for offshore funds at like €60 billion. BoE puts total hedge fund gilt repo at <£100B. Levered fund short UST futures are >$1 *trillion* and repo borrowing is >$2.5 trillion.

@StevenKelly49 Yet outside of the U.S. and maybe U.K. it's not clear to me this is anything like the same scale of exposures?.

As dealers rely more on MMF repo, repo rates also become more sensitive to reserve changes. A marginal drop in reserves now forces them to bid harder for cash to maintain smaller and smaller buffers.
