A new report from Bank of America shows that $18 billion per day on average was moved into money market funds since Mar. Money market funds also park their government bonds with the respective central banks through a program called a "reverse repurchase agreement." The table below shows over 35 widely traded money market funds available as ETFs worldwide. Regulators in the United States also prevent money market funds from holding more than 5% of their assets in illiquid assets. Vanguard, another provider of money market funds, also says the funds are "not recommended for investors seeking an increase in the value of investments over the long-term."
