RESERVE

(n.) Usually, the uninvested cash kept on hand for this purpose, called the real reserve. In Great Britain the ultimate real reserve is the gold kept on hand in the Bank of England, largely represented by the notes in hand in its own banking department; and any balance which a bank has with the Bank of England is a part of its reserve. In the United States the reserve of a national bank consists of the amount of lawful money it holds on hand against deposits, which is required by law to be not less than 15 per cent (U. S. Rev. Stat. secs. 5191, 5192), three fifths of which the banks not in a reserve city (which see) may keep deposited as balances in national banks that are in reserve cities (U. S. Rev. Stat. sec. 5192).
