Bisnis, JAKARTA - Several state-owned enterprises (BUMN) have reported annual pension fund investment yields below 2%, raising suspicions of corruption. The accumulation of pension funds is considered inadequate with such a low yield.

In comparison, bank-timed deposits, a common and relatively safe investment instrument, typically yield around 2% to 7% per year.

Government Bonds, which depend on market conditions, generally yield around 5% to 9% per year.

Another investment instrument, mutual funds, collects funds from various investors and is managed by professional investment managers. The yields of mutual funds vary depending on the type and performance of their investment portfolios. Equity mutual funds typically yield 5% to 15% per year, while obligation or fixed-income mutual funds yield 4% to 9% per year.
