Central banks

The Fed has shrunk since its peak while the Bank of Japan remains larger relative to GDP

Total assets of five major central banks, each from its own primary portal or from FRED where FRED is the publisher's machine-readable mirror, on one comparable percent-of-GDP scale and in native currency. The Fed's balance sheet peaked at $8.97T (34.5% of GDP) on Apr 13, 2022 and quantitative tightening has since taken it to $6.76T. The Bank of Japan's peaked at 125.8% of GDP, 91 points above the Fed's peak share, and still stands at 106.0%. The QE eras, the 2020 spike, and each bank's unwind are all visible below.

Quantities here, rates elsewhere. This page carries balance-sheet stocks; the policy rates these banks set live on the financial-conditions page (US, seven decades) and on each country page (BIS policy-rate series, 48 economies plus the euro area). Each series here is displayed with attribution to the publishing central bank; the People's Bank of China is deliberately absent because its monthly balance sheet has no stable machine-readable release (see the methodology).

Central-bank balance sheets

The Bank of Japan's balance sheet peaked at 125.8% of GDP

Monthly total assets for the Fed, ECB, BoJ, BoE and SNB as a percent of annual nominal GDP over their available histories through each bank's latest observation. That is the one scale on which a $6.76 trillion and a ¥644 trillion balance sheet can sit side by side. The Bank of Japan is the outlier of the group, with its peak on Aug 31, 2024 against the Fed's 34.5% peak; the SNB, a small economy holding a large FX portfolio, reached 135.2%. GDP denominators are annual (GMD 2026_06 for the US, Japan, UK, and Switzerland; ECB euro-area accounts for the Eurosystem), with the newest actual carried forward for the most recent observations.

Quantitative tightening, measured from each peak

Every value computed from the series as published: the all-time peak, the latest print, and the distance between them. The Fed has shed $2.21 trillion (24.6%) since Apr 13, 2022; the ECB 33.0% since Jun 24, 2022; the BoJ, the last to peak, is down 15.8% from Aug 31, 2024.

Federal Reserve balance sheet

MBS holdings have run off since their $2.74 trillion peak

Weekly Federal Reserve assets in USD trillions over the full H.4.1 histories, with Wednesday levels for total assets, US Treasuries held outright and agency mortgage-backed securities. MBS holdings were zero before 2009 and have been running off since their peak on Apr 13, 2022; the gap between the total and the two held-outright lines is everything else on the balance sheet (loans, repos, swap lines, and other assets), which is what spiked in 2008 and March 2020 before the asset purchases did.

Each bank in its own currency

The same five series in the units each institution publishes: no FX conversion, no rebasing. Frequencies differ by source: weekly for the Fed and the Eurosystem, monthly for the BoJ and SNB, quarterly for the BoE (whose consolidated balance sheet starts Sep 30, 2013 and publishes with a five-quarter lag).
