History of the NYSE: How the Buttonwood Agreement Started It All

Discover how 24 brokers meeting under a buttonwood tree in 1792 created the foundation for what would become the world's largest stock exchange—a story of trust, structure, and the birth of modern financial markets.

Introduction

The New York Stock Exchange (NYSE) is known today as one of the most important financial markets in the world. But it had humble beginnings.

The story begins in New York City in 1792, when a small group of brokers and merchants made a simple agreement under a tree. This document—called the Buttonwood Agreement—laid the foundation for the NYSE.

What Was Going On Before 1792?

In the late 1700s, after the American Revolution, there was growing trade in the new United States. People bought and sold government bonds, bank shares and other financial instruments.

But the system was informal. Brokers met in coffee houses, on street corners, and under trees—the rules were not clear.

⚠️ Problems with Informal Trading

  • •Unfair practices and manipulation
  • •Different commission rates causing confusion
  • •Uncertainty in trades and settlements
  • •Market perceived as too risky for many investors

The Buttonwood Agreement: A Simple Pact, Big Impact

đź“… Date: May 17, 1792

📍 Location: Wall Street & Water Street, Lower Manhattan

👥 Participants: 24 brokers and merchants

On May 17, 1792, twenty-four brokers and merchants met in Lower Manhattan, at the corner of Wall Street and Water Street, near what was then under a "buttonwood" (sycamore) tree.

They signed a brief document that became known as the Buttonwood Agreement.

What did they agree to?

They agreed to trade exclusively among themselves (i.e., those who signed would prefer each other).

They set a standard minimum commission rate: one-quarter of one per cent (0.25%) on trades.

They agreed to bring order and trust into their business.

Though this was not yet a full formal exchange as we know today, it was the first time a group of traders committed to a shared set of standards and rules. This was a milestone.

From Agreement to Exchange: The Next Steps

After the Buttonwood Agreement:

1

1793

The brokers soon moved from meeting under the tree to having a gathering place. They used the Tontine Coffee House on Wall & Water streets as one of their meeting places.

2

1817

The group formalised their business into the "New York Stock & Exchange Board".

3

1863

The name changed to the New York Stock Exchange (NYSE) as it is today.

These steps show how a simple pact grew into a structured marketplace, and then into a major stock exchange.

Why It Mattered

Why is the Buttonwood Agreement and the formation of the NYSE important?

Trust & Structure

By setting rules, the brokers improved confidence in the marketplace.

Standardisation

With fixed minimum commissions and exclusivity among members, practices became more uniform.

Growth of Markets

Over time, more companies, more investors and more trades participated, helping the economy grow.

Legacy

The NYSE became a model for how modern stock exchanges operate—organized, regulated, and centralised.

A Few Key Facts to Remember

Date: May 17, 1792

Location: Outside 68 Wall Street (or near the corner of Wall & Water Streets) under a buttonwood (sycamore) tree

Number of signers: 24 brokers/merchants

Minimum commission agreed: 0.25% (one quarter of one per cent)

Evolution: Agreement → trading gathering → 1817 Board → 1863 NYSE

Conclusion

What began under a tree in Lower Manhattan has grown into one of the largest stock exchanges in the world.

The Buttonwood Agreement may seem modest—a document signed by 24 men setting simple rules—but its influence was powerful. It marked the shift from informal, unregulated trading to the structured, regulated markets we know today.

Understanding this origin helps us appreciate how markets evolved, how trust and rules matter, and how big institutions often start with simple ideas.
