 In a July 2013 article, David Kocieniewski, a journalist with "The New York Times" accused Goldman Sachs and other Wall Street firms of "capitalizing on loosened federal regulations" to manipulate "a variety of commodities markets", particularly aluminum, citing "financial records, regulatory documents, and interviews with people involved in the activities".After Goldman Sachs purchased aluminum warehousing company Metro International in 2010, the wait of warehouse customers for delivery of aluminum supplies to their factories - to make beer cans, home siding, and other products - went from an average of 6 weeks to more than 16 months, "according to industry records".
