So let's assume the $10 billion in available assets from the state-owned bank were used to repurchase these bonds. The state would have saved $9.5 billion, less the cost of funds.
It is not clear from the above-cited source what the length of the bond issue was, but assume it was for 20 years, making the interest rate about 3.5%. The cost of one billion dollars in capital for 20 years at 7% would be $2.87 billion, and the cost of $11.1 billion in deposits at 0.5% would be $1.164 billion. So the total cost of funds would be $4.034 billion. Deducted from $9.5 billion, that leaves about $5.5 billion in savings or profit over 20 years. That's $5.5 billion generated with money the state already has sitting idle, requiring no additional borrowing or taxpayer funds.
What about risk? What if one of the cities or state agencies whose money is held in the investment pool wants to pull that money out? Since it is held in the bank as deposits, it would be immediately liquid and available, as all deposits are. And if the bank then lacked sufficient liquidity to back its assets (in this case the repurchase of its own bonds), it could in the short term do as all banks do -- borrow from other banks at the Fed funds rate of about 0.35%, or from the Federal Reserve Discount Window at about 0.75%. Better yet, it could simply liquidate some of the $56 billion remaining in the PMIA and deposit that money into its state bank, where the funds would continue to earn 0.5% interest as they are doing now.
Assume that from its $5.5 billion in profits, the bank then repaid the pension funds their $1 billion initial capital investment. That would leave $4.5 billion in profit, free and clear -- a tidy sum potentially generated by one man sitting in an office shuffling computer entries, without new buildings, tellers, loan officers or other overhead. That capital base would be sufficient to capitalize about $40 billion in new loans, all generated without cost to the taxpayers.
A California New Deal
The bullet train example is a simple way to illustrate the potential of a state-owned bank, but there are many other possibilities for using its available assets. As the BND did after building up its capital base, the bank could advance loans at reasonable rates for local businesses, homeowners, students, school districts, and municipalities seeking funds for infrastructure.
These loans would be somewhat riskier than buying back the state's own bonds, and they would involve variable time frames. Like all banks, the state bank could run into liquidity problems from borrowing short to lend long, should the depositors unexpectedly come for their money. But again, that problem could be fixed simply by liquidating some portion of the money remaining in the PMIA and depositing it in the state-owned bank, where it would earn the same 0.5% interest it is earning now.
Here is another intriguing possibility for avoiding liquidity problems. The bank could serve simply as intermediator, generating loans which would then be sold to investors. That is what banks do today when they securitize mortgages and sell them off. Risk of loss is imposed on the investors, who also get the payment stream; but the bank profits as well, by receiving fees for its intermediating functions.
The federally-owned Reconstruction Finance Corporation (RFC) did something similar when it funded a major portion of the New Deal and World War II by selling bonds. This money was then used for loans to build infrastructure of every sort and to finance the war. According to a US Treasury report titled Final Report of the Reconstruction Finance Corporation (Government Printing Office, 1959), the RFC loaned or invested more than $40 billion from 1932 to 1957 (the years of its operation). By some estimates, the sum was about $50 billion. A small part of this came from its initial capitalization. The rest was borrowed -- $51.3 billion from the US Treasury and $3.1 billion from the public. The RFC financed roads, bridges, dams, post offices, universities, electrical power, mortgages, farms, and much more, while at the same time making money for the government. On its normal lending functions (omitting such things as extraordinary grants for wartime), it wound up earning a total net income of $690 million.
North Dakota has led the way in demonstrating how a state can jump-start a flagging economy by keeping its revenues in its own state-owned bank, using them to generate credit for the state and its citizens, bypassing the tourniquet on the free flow of credit imposed by private out-of-state banks. California and other states could do the same. They could create jobs, restore home ownership, rebuild infrastructure and generally stimulate their economies, while generating hefty dividends for the state, without increasing debt levels or risking public funds -- and without costing taxpayers a dime.
