12 C.F.R. § 250.413
Section 32 of the Glass-Steagall Act (12 U.S.C. 78 ) prohibits any officer, director, or employee of any corporation or unincorporated association, any partner or employee of any partnership, and any individual, primarily engaged in the issue, flotation, underwriting, public sale, or distribution, at wholesale or retail, or through syndicate participation, of stocks, bonds, or other similar securities, from serving at the same time as an officer, director, or employee of any member bank of the Federal Reserve System. The Board is of the opinion that to the extent that a company, other entity or person is engaged in securities activities that are expressly authorized for a state member bank under section 16 of the Glass-Steagall Act (12 U.S.C. 24(7) , 335 ), the company, other entity or individual is not engaged in the types of activities described in section 32. In addition, a securities broker who is engaged solely in executing orders for the purchase and sale of securities on behalf of others in the open market is not engaged in the business referred to in section 32.
