# Treaties of Commerce

## Definition

Formal agreements between nations that grant preferential trade privileges to one country over others, typically by allowing certain goods to enter duty-free or at reduced rates, or by exempting specific goods from duties that apply to similar products from other nations. These arrangements create monopolistic advantages for merchants and manufacturers of the favoured country while disadvantaging those of the favouring country.

## Source Chapter

Book IV, Chapter 6

## Context

Smith analyzes treaties of commerce as a specific type of trade restriction that creates monopolistic advantages. He argues that while such treaties benefit the favoured country's merchants, they harm the favouring country's economy by forcing it to pay higher prices for goods and sell its own produce more cheaply. Smith uses the 1703 treaty between England and Portugal as a case study to demonstrate how these arrangements work in practice.
