The Education of Ben Bernanke
“I think Bernanke is in a very difficult situation,” Paul Volcker told me. Volcker was the Fed chief who preceded Greenspan and who conquered, painfully, the great inflation of the 1970s and early ’80s. (He was chairman from 1979 to 1987.) “Too many bubbles have been going on for too long,” Volcker added. “The Fed is not really in control of the situation.”

8. Administration of Affairs; Extension of Credit

Said board of directors shall administer the affairs of said bank fairly and impartially and without discrimination in favor of or against any member bank or banks and may, subject to the provisions of law and the orders of the Board of Governors of the Federal Reserve System, extend to each member bank such discounts, advancements, and accommodations as may be safely and reasonably made with due regard for the claims and demands of other member banks, the maintenance of sound credit conditions, and the accommodation of commerce, industry, and agriculture. The Board of Governors of the Federal Reserve System may prescribe regulations further defining within the limitations of this Act the conditions under which discounts, advancements, and the accommodations may be extended to member banks. Each Federal reserve bank shall keep itself informed of the general character and amount of the loans and investments of its member banks with a view to ascertaining whether undue use is being made of bank credit for the speculative carrying of or trading in securities, real estate, or commodities, or for any other purpose inconsistent with the maintenance of sound credit conditions; and, in determining whether to grant or refuse advances, rediscounts or other credit accommodations, the Federal reserve bank shall give consideration to such information. The chairman of the Federal reserve bank shall report to the Board of Governors of the Federal Reserve System any such undue use of bank credit by any member bank, together with his recommendation. Whenever, in the judgment of the Board of Governors of the Federal Reserve System, any member bank is making such undue use of bank credit, the Board may, in its discretion, after reasonable notice and an opportunity for a hearing, suspend such bank from the use of the credit facilities of the Federal Reserve System and may terminate such suspension or may renew it from time to time.
