To prevent conflicts of interest and protect the public interest, many countries impose restrictions on the securities trading behavior of members of Congress. These restrictions include prohibiting the use of non-public information for stock trading, requiring the disclosure of assets and transaction records, and banning trading of specific assets during certain time periods. The aim is to avoid "insider trading" and the act of seeking personal gain through legislation, thus maintaining the credibility of legislative bodies. For example, the U.S. STOCK Act explicitly requires members of Congress to disclose their securities transactions to ensure transparency. Strengthening regulatory and penal mechanisms helps prevent corruption and enhance public trust in the government.
