Which article of the U.S. Constitution grants the power to coin money and make treaties?

The power to coin money and make treaties is granted by Article I of the U.S. Constitution. This article establishes the legislative branch of the government, which includes Congress. Within Article I, Section 8 lists the specific powers of Congress, including the power to regulate commerce, declare war, and, most relevantly, to coin money.

Additionally, while the power to make treaties is specifically granted to the president with the advice and consent of the Senate, the inclusion of both powers within the legislative framework underscores the importance of controlled economic and diplomatic authority in maintaining a stable government. Article II, on the other hand, relates to the executive branch, Article III pertains to the judicial branch, and Article IV focuses on states' relations, which do not address the powers associated with currency or treaties directly. Thus, the correct focus on Article I highlights its central role in defining important economic and treaty-related powers of the government.
