In this study we assess the effects of financial development on private saving in Iran. As capital accumulation is the most important factor in economic growth, therefore the evaluation of effects of developments in financial system on saving (that is recently going to join to' global economy based on liberalization principles) is seemed very important. After identifying of financial system in Iran and determination of effective variables on private saving, using a statistical method, named principle components, we made a financial sector development index. The most important results which were achieved are: a) in the last three decades Iran's financial sector has been very small. b) Development of financial system (constrained with quantitative banking indices) has had a negative effect on saving in Iran.
