(a) Rules and regulations for extension of credit; standard for initial extension; undermargined accounts

For the purpose of preventing the excessive use of credit for the purchase or carrying of securities, the Board of Governors of the Federal Reserve System shall, prior to October 1, 1934, and from time to time thereafter, prescribe rules and regulations with respect to the amount of credit that may be initially extended and subsequently maintained on any security (other than an exempted security or a security futures product). For the initial extension of credit, such rules and regulations shall be based upon the following standard: An amount not greater than whichever is the higher of—

(1) 55 per centum of the current market price of the security, or

(2) 100 per centum of the lowest market price of the security during the preceding thirty-six calendar months, but not more than 75 per centum of the current market price.


Such rules and regulations may make appropriate provision with respect to the carrying of undermargined accounts for limited periods and under specified conditions; the withdrawal of funds or securities; the substitution or additional purchases of securities; the transfer of accounts from one lender to another; special or different margin requirements for delayed deliveries, short sales, arbitrage transactions, and securities to which paragraph (2) of this subsection does not apply; the bases and the methods to be used in calculating loans, and margins and market prices; and similar administrative adjustments and details. For the purposes of paragraph (2) of this subsection, until July 1, 1936, the lowest price at which a security has sold on or after July 1, 1933, shall be considered as the lowest price at which such security has sold during the preceding thirty-six calendar months.
