title: With the Fed’s reverse repo facility nearly drained, the system now leans on reserves as the main buffer.
description: "Right now, they sit at ~$3.2T, which the Fed still calls “ample.” Governor Waller has suggested ~$2.7T is a safe floor, while Barclays sees end-September reserves sliding closer to that line. \nThe problem? Treasury bill issuance and QT are still pulling cash out each month. \n\nWith no RRP cushion left, every dollar matters more and once reserves fall into the danger zone, stress tends to show up fast in repo markets, auctions, and short-term funding.\nSource: StockMarket.News @_Investinq on X"
