What power does the Constitution give Congress concerning trade?

The Constitution grants Congress the power to regulate international trade primarily through the Commerce Clause, which is found in Article I, Section 8. This clause empowers Congress to regulate commerce with foreign nations as well as among the states and with Indian tribes. This regulatory power includes establishing tariffs, addressing trade agreements, and overseeing trade laws that affect international commerce, ensuring that trade is conducted fairly and effectively across borders.

The other options, while they may seem related to trade, do not correctly represent the specific authority outlined in the Constitution. For instance, monopolizing trading companies is not permissible under the Constitution, as it would contradict the principles of free commerce and competition. Conducting trade negotiations with foreign nations is typically an executive function and not under the direct purview of Congress, although Congress does play a role in approving treaties. Lastly, the control of foreign currency is more aligned with monetary policy typically managed by the Treasury and the Federal Reserve, rather than Congress itself, which focuses on regulation and legislation. Thus, the specific power given to Congress regarding trade is accurately represented by the ability to regulate international trade.
