Finance History | 68 Wall Street, 17 May 1792 — Twenty-Four Brokers Made Trust a Membership Rule

Two sentences and twenty-four signatures were enough to define who could be trusted in New York’s small securities market.

On 17 May 1792, twenty-four brokers signed the Buttonwood Agreement after the young United States had endured its first financial panic. The New York Stock Exchange treats the document as its founding compact.

The brokers made two promises. They would charge no less than one-quarter of one percent of the specie value as commission, and they would give one another preference when arranging trades.

The mechanism was membership before there was an exchange building. Preference kept business inside a known circle, while the commission floor stopped members from winning orders simply by undercutting one another.

That arrangement reduced one kind of risk by making repeated dealing more valuable than a single opportunistic trade. It also created a cartel: customers gained a more orderly market, but the members protected their own access and fees.

The document did not create a corporation, a trading floor, or a complete rulebook. Brokers continued to meet informally until 1817, when they adopted a constitution for the New York Stock and Exchange Board and rented a room at 40 Wall Street.

The famous tree belongs to tradition rather than to the text. The agreement says that it was executed in New York, but it does not mention a buttonwood tree or give an address.

This pin therefore marks the traditional site outside 68 Wall Street, between William and Pearl Streets, rather than a location proved by the surviving sheet. The distinction matters because the agreement is strong enough without turning an inherited story into a documented coordinate.

The image shows the compact itself: a short rule among brokers that became the institutional ancestor of the New York Stock Exchange.
