A central bank’s balance sheet reflects its role as the monetary authority. Unlike a commercial bank, a central bank’s liabilities function directly as baseline money within the national economy. [1]
Standardized Central Bank Asset & Liability Matrix
The balance sheet is organized into clear, predictable categories that reflect policy actions:
  Balance Sheet Side |   Primary Account Category Type   |   Operational Policy Purpose
---------------------+-----------------------------------+-----------------------------------------
  Assets             | Sovereign Bond Portfolios         | Open market intervention assets
  Assets             | Foreign Currency Reserves & Gold  | FX stabilization & international buffers
  Liabilities        | Currency in Circulation           | Physical banknotes held by the public
  Liabilities        | Commercial Bank Reserve Accounts  | Operational settlement money pools

During expansionary policy phases, like Quantitative Easing (QE), the central bank expands its balance sheet by purchasing sovereign bonds on the open market, paying for them by creating new digital reserves in commercial bank accounts.
