Planning for retirement income is becoming increasingly important as governments look for ways to cut spending. So-called sovereign funds, set up by countries to save for retiree payments, are becoming increasingly popular, Watson Wyatt said.
The Government Employees Pension Fund of South Africa and Canada Pension both joined the ranks of the 20 largest funds in the past three years, Watson Wyatt said.
U.S. pension funds account for 43 percent of the assets in the 300 largest funds, Japanese funds oversee 15 percent and UK funds are responsible for 7.1 percent, the survey showed.
