But the reservoir of other people’s money, from which the investment bankers now draw their greatest power, is not the life insurance companies, but the banks and the trust companies. Bank deposits represent the really quick capital of the nation. They are the life blood of businesses. Their effective force is much greater than that of an equal amount of wealth permanently invested. The 34 banks and trust companies, which the Pujo Committee declared to be directly controlled by the Morgan associates, held $1,983,000,000 in deposits. Control of these institutions means the ability to lend a large part of these funds, directly and indirectly, to themselves; and what is often even more important, the power to prevent the funds being lent to any rival interests. These huge deposits can, in the discretion of those in control, be used to meet the temporary needs of their subject corporations. When bonds and stocks are issued to finance permanently these corporations, the bank deposits can, in large part, be loaned by the investment bankers in control to themselves and their associates; so that securities bought may be carried by them, until sold to investors. Or these bank deposits may be loaned to allied bankers, or jobbers in securities, or to speculators, to enable them to carry the bonds or stocks. Easy money tends to make securities rise in the market. Tight money nearly always makes them fall. The control by the leading investment bankers over the banks and trust companies is so great, that they can often determine, for a time, the market for money by lending or refusing to lend on the Stock Exchange. In this way, among others, they have power to affect the general trend of prices in bonds and stocks. Their power over a particular security is even greater. Its sale on the market may depend upon whether the security is favored or discriminated against when offered to the banks and trust companies, as collateral for loans. Furthermore, it is the investment banker’s access to other people’s money in controlled banks and trust companies which alone enables any individual banking concern to take so large part of the annual output of bonds and stocks. The banker’s own capital, however large, would soon be exhausted. And even the loanable funds of the banks would often be exhausted, but for the large deposits made in those banks by the life insurance, railroad, public service, and industrial corporations which the bankers also control. On December 31, 1912, the three leading life insurance companies had deposits in banks and trust companies aggregating $13,839,189.08. As the Pujo Committee finds:
