The Commodity Futures Trading Commission (CFTC) enforces a range of regulations in the commodity futures markets to ensure fair and transparent trading practices. Some of the key regulations include position limits to prevent excessive speculation, registration and oversight of commodity futures traders and brokers, reporting and disclosure requirements for market participants, and anti-fraud and anti-manipulation rules to prevent abusive practices. The CFTC also enforces rules related to trading on designated contract markets, including requirements for exchange self-regulation, price transparency, and orderly trading. Additionally, the CFTC oversees the protection of customer funds held by futures commission merchants and takes enforcement action against individuals or entities that violate its rules.
