Fed balance sheet shrinks to $6.73T, reserves hit critical $356.2B as QT drains liquidity
MarketsFN Data Team
The H.4.1 — Factors Affecting Reserve Balances — is the Federal Reserve's weekly balance sheet statement, released every Thursday at 4:30 PM ET. It shows the Fed's total assets (currently $6.73T) and how those assets are funded (primarily through currency in circulation and bank reserve balances). Tracking the H.4.1 week-by-week reveals the pace of Quantitative Tightening (QT) and how much liquidity the Fed is withdrawing from the financial system.
Quantitative Easing (QE) — the Fed buys Treasuries and MBS, expanding its balance sheet and injecting reserves into banks, making credit cheap and abundant. The Fed's balance sheet peaked at $8.96T in April 2022. Quantitative Tightening (QT) reverses this: the Fed lets bonds mature without reinvesting, shrinking its balance sheet and draining reserves. The Fed has now removed $2.23T (24.9%) from the peak — tightening financial conditions.
Reserve balances are funds that commercial banks hold at the Fed. Currently at $356.2B, they represent the banking system's primary liquidity buffer. When reserves fall too low, banks scramble for overnight funding — exactly what triggered the September 2019 repo market crisis (reserves had fallen to ~$1.4T then). Economists estimate the "ample reserves" floor is around $1,500B. Below that, money market rates can spike unpredictably.
Two key drains on reserves: the Overnight Reverse Repo (RRP) facility, where money market funds park excess cash at the Fed (currently $0.7B, down from a $2.5T peak) — as this drains, that cash re-enters the banking system. The Treasury General Account (TGA) — the government's checking account at the Fed ($950.7B) — drains reserves when it rises (tax receipts) and injects reserves when it falls (government spending). Together, RRP + TGA movements drive weekly reserve volatility.
The Fed's balance sheet stands at $6.73T, down $2.23T (24.9%) from its April 2022 peak, with reserves plunging to $356.2B — nearing levels that could disrupt short-term funding markets as liquidity grows scarce.
The Fed has reduced its balance sheet by $2.23T (24.9%) from the April 2022 peak of $8.96T, with weekly declines averaging below the $95B monthly cap. The $6.46T securities portfolio (96% of assets) shows Treasury runoff ($4.55T) outpacing MBS ($1.91T), suggesting QT is proceeding slower on MBS due to slower prepayments. The $13.2B weekly securities decline indicates the Fed is not maxing out its runoff capacity.
Bank reserves have fallen to $356.2B, far below the estimated ample-reserves floor of ~$1,500B and nearing the ~$600B critical threshold. A 7.0% YoY drop signals rapid drain, exacerbated by the overnight RRP facility's collapse to $0.7B (from ~$2.5T peak). This suggests the banking system is approaching 2019-style scarcity, risking repo market stress if reserves fall further.
The Treasury General Account sits at $950.7B, up 41.4% YoY. A high TGA drains reserves as tax receipts and bond issuance lock up liquidity. The recent $2.9B WoW decline hints at modest relief, but upcoming debt ceiling deadlines or seasonal issuance could swing the TGA sharply, impacting reserve dynamics in the weeks ahead.

Watch for Fed signals on QT pacing as reserves near scarcity thresholds (~$600B). Upcoming FOMC meetings may address runoff caps, while Treasury issuance plans (e.g., bill supply shifts) could temporarily inject reserves. The Fed faces a tightening liquidity squeeze, with market stability hinging on reserve levels and TGA movements.
