System Open Market Account Holdings

The System Open Market Account (SOMA), managed by the Federal Reserve Bank of New York, contains dollar-denominated assets acquired via open market operations. These securities serve three purposes:

  • Collateral for U.S. currency in circulation and other reserve factors that show up as liabilities on the Federal Reserve System's balance sheet
  • A tool for the Fed’s management of reserve balances
  • A store of liquidity in the event an emergency need for liquidity arises
