Pension funds typically have large amounts of money to invest and are the major investors in listed and private companies. They are especially important to the stock market where large institutional investors dominate. The largest 300 pension funds collectively hold about USD$6 trillion in assets. In 2012, PricewaterhouseCoopers estimated that pension funds worldwide hold over $33.9 trillion in assets (and were expected to grow to more than $56 trillion by 2020), the largest for any category of institutional investor ahead of mutual funds, insurance companies, currency reserves, sovereign wealth funds, hedge funds, or private equity.
The Federal Old-age and Survivors Insurance Trust Fund in the United States, which oversees $2.66 trillion in assets, is the world's largest public pension fund.
