Bank of America Merrill Lynch said investors were quick to inject money into government-rated bond funds rated at an investment-grade level to record fixed-income instruments, the fourth-largest weekly influx, as investors sought to guard against the risk of a global recession. A total of $ 16 billion was injected into bond funds in the week ending Wednesday, the bank said, citing IBFR data. Bond-rated funds have withdrawn $ 10.7 billion in flows, the fifth-largest flow in a week for this asset class, while government bonds received $ 4.7 billion. Equity funds experienced a limited outflow of $ 4.7 billion during the week, the data showed.
