In the midst of the panic of 1792, a group of 24 brokers and merchants met to discuss possible regulations in an attempt to restore trust in the securities business. On 17 May they met again to sign the Buttonwood Agreement, named after the buttonwood tree in New York City’s Wall Street where they traditionally met to conduct their trades.
The Buttonwood Agreement was significant for two regulatory reasons. Firstly, the brokers guaranteed that they would not try to undercut each other by setting a fixed floor commission rate of 0.25%. This reduced the risk of manipulative pricing and competition between brokers. Secondly, the signatories agreed to only ever trade with each other, closing the system to outsiders who might be less scrupulous. With the knowledge that every broker operated by the same rules, they could trust that the market prices were fair and that deals would be honored. These original New York stockbrokers traded from the Tontine Coffee House at 82 Wall Street before moving to their first dedicated trading space in 1817.
