The trend of yields on institutional investments has become a matter of considerable importance for an increasing number of people. The growth of institutional assets has been widely publicized in recent years, but little has been said about the ultimate ownership of this wealth. The fact is that the ownership of the resources of financial institutions becomes more widespread every year. There are now estimated to be some 83 million life insurance policyholders as compared with 64 million in I938, 53 million in 1927, and only io million in i900. There are nearly I5 million regular mutual savings bank accounts as compared with i2 million in I938earlier data are not available. The increase in the number of savers and investors in savings and loan associations is even more impressive. The I936 total was 4.3 million. By I950 the total had increased to I0.7 million. Comparable figures on the ownership of commercial bank deposits apparently are not available, but these too have undoubtedly increased substantially in recent years. This paper will first review the trend of yields on the investments of life insurance companies, commercial banks, mutual savings banks, and savings and loan associations, and then consider the implications of these trends in the light of the growth of institutional assets and their increasingly widespread ultimate ownership.
