Dark pools are a significant and controversial aspect of modern financial markets in both the USA and Brazil. In the USA, they represent a major portion of equity trading volume and are strictly regulated by the SEC. In Brazil, they are increasingly relevant as institutional investment grows, though they remain less prevalent than in North American markets. The term carries connotations of opacity and potential regulatory concerns in both cultures.
