Dragan Kovacevic said that the yield of Mirex index over the last year came to 8.63 percent.
Mandatory pension funds currently have over 1.2 million insurees.
Kovacevic described the Croatian financial sector as stable, adding that pension funds were an important factor in that sector, particularly on the money market.
The funds invest 90 percent of their assets in Croatia, with government bonds accounting for 72 percent of the investments.
The remaining 10 percent of their assets are invested on foreign markets.
Kovacevic said Hagena would hold a conference on pension funds and money markets in mid-October.
