Fed Balance Sheet

The Fed's balance sheet is the other lever of monetary policy — alongside the Fed Funds Rate. When the Fed buys bonds, balance-sheet assets expand (QE), reserves flood the system, and financial conditions ease independently of where the policy rate sits. When the Fed lets bonds roll off without replacement, assets shrink (QT), reserves drain, and conditions tighten in the background even if no rate change happens. So this card answers a question the policy rate alone can't: is the Fed actively pumping liquidity in or pulling it out, and at what speed? The card shows YoY % change rather than the raw level for one reason — the absolute size has structurally shifted (~$800B pre-2008, ~$9T at 2022 peak, currently mid-$6T), so any rating against historical levels would be meaningless. YoY change reads identically across regimes. Watch zones to read it: solidly positive (above ~+5%) means active QE or emergency facility expansion (2008-09, 2020-21, 2023's BTFP bump for the SVB episode); around zero means the balance sheet is steady or being maintained; solidly negative (below ~-5%) means active QT, which has historically preceded financial accidents (2018-19 repo market squeeze, 2023 regional bank stress) because draining reserves out of the system surfaces fragilities that abundant liquidity was masking. The historical pattern matters here: the Fed almost never expands the balance sheet preemptively — QE is reactive, triggered by an identified problem. So a high reading on this card typically means the Fed is responding to something already broken, while a low reading means QT is grinding away in the background and the question is whether this cycle will see a 2019-style pivot before something cracks. Pair with Real Fed Funds Rate (rate-side stance) and ANFCI (financial-conditions outcome) for the full Fed-stance picture: balance sheet tells you whether liquidity is flowing in or out, real rate tells you how restrictive the policy rate is, ANFCI tells you whether either lever is reaching the financial system.
