Previously securities exchange had been intermediated by the auctioneers who also conducted more mundane auctions of commodities such as wheat and tobacco. On May 17, 1792 twenty four brokers signed the Buttonwood Agreement which set a floor commission rate charged to clients and bound the signers to give preference to the other signers in securities sales. The earliest securities traded were mostly governmental securities such as War Bonds from the Revolutionary War and First Bank of the United States stock, although Bank of New York stock was a non-governmental security traded in the early days.
