23 Feb 2018 Berkshire Hathaway now one of world’s largest owners of Treasury bills ( Portfolio )

Berkshire has an outsize presence in the $2 trillion market for Treasury bills, a type of government debt that matures in a year or less. It held more bills around the end of the third quarter than large countries such as China and the U.K. It also had more at that time than the $13.5 billion held collectively by a group of 23 primary bond dealers that are obligated to underwrite U.S. government debt sales.
