In the 1922 case of Board of Trade of the City of Chicago v. Olsen, the United States Supreme Court upheld a federal law that regulated grain futures contracts. The Grain Futures Act was challenged by the Chicago Board of Trade on grounds that it violated their members' rights to trade freely and interfered with state commerce regulations. However, in a unanimous decision, Justice Oliver Wendell Holmes Jr., writing for the court, ruled that Congress had authority under its Commerce Clause powers to regulate these transactions because they were not confined within individual states but had national implications affecting interstate commerce. This ruling affirmed federal regulatory power over speculative trading practices which could potentially destabilize markets and harm public interest.

In the dissenting opinion of the case Board of Trade of The City Of Chicago v. Olsen, Justice McReynolds expressed his disagreement with the majority's interpretation and application of the Commerce Clause in relation to futures contracts on grain. He argued that these transactions were not a form or part of interstate commerce because they did not involve any actual movement or transportation across state lines but were merely agreements for future delivery. Therefore, he believed that Congress lacked constitutional authority to regulate them under its power over interstate commerce as it had done through the Grain Futures Act. Furthermore, he contended that even if such contracts could be considered as affecting interstate commerce indirectly, this still would not justify federal regulation since their impact was too remote and indirect according to established precedents at that time.
