SUBJECT: Limited-Purpose Banking
Despite nine months of intense intervention by two Administrations, US financial markets and the overall economy have melted down. As you know, more than ten million Americans are now unemployed and our GDP is falling. Everyone realizes that we need the right financial fix, and need it right now. The President is on task, and there is no question that you and your colleagues are working day and night to solve this terrible crisis. Your efforts merit our deepest respect and admiration. Unfortunately, you appear to be misdiagnosing the problem and, consequently, applying medicine that won't work.
Trust, Not Liquidity
The fundamental problem facing our financial system is not insufficient liquidity, a shortage of credit or capital inadequacy. The fundamental problem is a well-deserved lack of trust between borrowers and lenders at nearly all levels. To be blunt, the financial sector played the big con and lost big time. No one is going to trust insider raters, banks that borrow to gamble, hedge funds that fake returns and insurers that concentrate rather than spread, risk. No one is going to trust assets that can't be disclosed, are self-custodied, are valued by models calibrated with limited data that ignore systemic risk - and that are parked in secrecy jurisdictions like Antigua. Above all, no one in his or her right mind is going to trust bankers with me-first business plans - people who have seemingly lost the capacity to distinguish between conscience and greed.
The fact that most financial players have been honest and that most financial plays over the past decade were sound now means nothing. Everyone has been tarred by the scale and implications of dishonest and selfish behavior among a not-so-small minority. Uncle Sam could buy every toxic asset on earth and stuff a "bad bank" to its gills, and we'd still have a banking crisis. When people buy things, they want to know what they're getting. They won't buy Tylenol if they don't trust that Tylenol is in fact in the bottle, and they won't buy bank paper at a decent rate or bank equity at a decent price if they can't trust what the bank is doing.
Recapitalizing the banks is therefore not the answer. Left to their own wiles, bank managers will take that new capital and invest it in their latest Sure Thing, largely in order to convince us to do the same. They'll do this because it's not their capital. Their livelihood flows from their commissions and bonuses, which are based on sales of the Sure Thing, not the return on it. And they'll collect their loot long before the Sure Thing slithers away down the proverbial rat-hole.
Raising capital requirements for banks is equally futile as a solution to the present crisis. Banks in trouble know that their liabilities are limited by their terms of incorporation, and that the only chance of surviving is doubling down on risky bets - which is exactly the behavior we have seen as several financial giants lumbered recently toward the precipice. How many Long-Term Capital Managements, Bear Stearns, Lehman Brothers, AIGs, Merrill Lynches and Madoffs do we need before we realize that we're not dealing here with moral hazard? We're dealing with immoral certainty.
Since the core problem is trust, it's not going to be solved by resurrecting a failed financial system. Nor can it be resolved by nationalizing the financial sector, which will throw out the baby with the bathwater and introduce all manner of political agendas into financial decision-making. Instead, the solution is to fundamentally redefine what a bank can and cannot do, so that we never again face financial collapse.
Limited-Purpose Banking
Strange as it may seem to so many who have grown used to the American financial subculture of the past few decades, the core purpose of banks and other financial corporations isn't to gamble with other people's money. That core purpose is instead to connect - that is, to intermediate between - suppliers and demanders of financing. In this respect, banks are no different from gas stations. Gas stations intermediate between suppliers of gas (refineries) and demanders of gas (drivers); they don't gamble on the price of gas and leave the country exposed to a huge common bet, the loss of which will lead nearly all of them to close down.
To re-establish trust and resurrect our financial system we need to limit banks and all other financial corporations to their original purpose: financial intermediation.
Here's how limited-purpose banking would work.
Every incorporated enterprise engaged in financial intermediation would operate strictly as a mutual fund company and live under a common set of rules. Whether they would call themselves commercial banks, investment banks, trust companies, hedge funds, savings and loans, mortgage brokers or something else would be immaterial. They would all be free to do the same thing - namely, intermediate, and to make a profit by charging for that service, but take no risks with their company's money.
Banks (shorthand for financial corporations) would sell only two things: checking account services and shares of mutual funds, which hold bonds, mortgages, stocks, private equity, real estate and other financial securities.
Consider first the banks' checking account operations. In the current system, banks take in customer deposits and are required to keep only ten percent in reserve against the possibility that customers will demand their deposits back right away. The other ninety percent is, in effect, the banks' gambling stakes. It is money banks can lend out on risky projects or spend on risky stocks or invest in risky private equity and real estate. If these investments work out, everyone's happy. If not, well, the bank gets to flip the problem to the FDIC (that is, to taxpayers), which insures the deposits. If everyone suddenly comes to believe, whether correctly or not, that the banks have lost their money, everyone will run to the teller windows and demand it back. It won't be there, as it wasn't there in 1873 or in 1930.
So we have a depository system that's very fragile because it is exposed to bank runs. Today, the FDIC is insuring close to $4 trillion dollars in deposits, and it's frankly very scary that it has less than $36 billion (just around one percent) in reserve to cover this massive liability. Were all Americans to panic and demand back their deposits, Uncle Sam would have to print up nearly $4 trillion on the spot - a formula for hyperinflation if ever there were one. Sound extreme? It is. But these are extreme times, and the public is getting close to full panic mode.
Under limited-purpose banking, bank runs could never arise. Every dollar deposited in a checking account would be held in cash or US Treasuries, meaning banks would hold not ten percent reserves, but 100 percent reserves against these liabilities. Banks would always have all of our money on hand, either in cold cash or short-term T-bills.
This is not a new idea. Three stellar economists - Irving Fisher, Frank Knight and Milton Friedman - proposed precisely this treatment of checking accounts, which they called narrow banking {1}. They wanted to end bank runs for good and, not just incidentally, also to give the government full control of the nation's money supply, what we call M1.
As you know, under today's system the size of M1 depends on how the banks handle their gambling stakes. If they "invest" all ninety percent, and those getting the ninety percent deposit them back into other banks, which then "invest" ninety percent of the "new" ninety percent and on and on, we can get a huge expansion of deposits. We economists call this daisy chain "the money multiplier" because deposits plus cash held by us in our pockets constitute M1. When banks lend or otherwise invest, M1 expands; when they don't lend, M1 contracts. Friedman and Anna Schwartz plausibly blamed the Great Depression on the Fed's failure to prevent the collapse of the money multiplier, and with it M1, as banks cut back their lending {2}.
Today, just as in the 1930s, we're seeing a huge (almost a fifty percent) decline in the money multiplier. This has forced Federal Reserve Chairman Ben Bernanke to expand the monetary base - to print massive amounts of money, in layman's terms - to stabilize M1. Printing all this money (Bernanke has more than doubled base money over the past year) holds its own risks, of course: If the multiplier shoots back up, we could see the money supply and prices explode.
To summarize, we've got a depository system that's subject to moral hazard, bank runs and wild swings in the money multiplier. In normal times these risks are theoretical; in times of crisis, they tend to ensure that we suffer maximum feasible calamity. It's not worth the risk, and limited-purpose banking would eliminate all three problems.
Now to the banks' second job under limited-purpose banking: selling bond, equity and real estate mutual funds. Let's start with bond funds.
Under our system banks would initiate but not hold loans. Banks would send their initiated loans, whether to individuals (for example, a mortgage) or businesses (for example, a credit line), to a new government agency - the Federal Financial Authority (FFA) - which would rate the loans after using tax records to verify the income reported and spot-checking the appraised value of collateral. Once processed by the FFA, the banks would package the fully disclosed, government-rated loans within mutual funds for purchase by the public. Once purchased, the loan would be activated. The public, not the banks, would own the mutual funds and hold the loans.
Banks could borrow money on their own account to buy office furniture, bank buildings and make other investments in their operations, but not to gamble. Banks would never be leveraged because their purpose is intermediation, not gambling. Bank owners, on the other hand - including the owners of holding companies that include banks and other kinds of businesses - would still be completely free to gamble on high-risk investments, but only with their own personal money, not with the bank's assets.
There is, of course, a clear precedent for government loan rating; namely, Fannie Mae and Freddie Mac's conforming loan standard. And the idea of securitizing loans within mutual funds isn't new either. What's new here is the scope of the rating system, the degree of disclosure and the absolute prohibition against banks taking risks.
Next consider bank issuance of mutual funds that hold stocks, private equity and real estate. Banks would sell shares of the mutual funds and use the proceeds to purchase these securities. The banks themselves, however, would not own any of the securities held within their mutual funds. They'd simply connect savers to investors and collect a fee for the service.
The FFA would audit the books of all publicly traded companies (to insure against any more Enrons), require full disclosure of the private equity and real estate being packaged within mutual funds, and establish a custodial system to ensure that title to all assets owned by mutual funds is secure and verified. Never again would a Bernie Madoff be free to custody his own accounts; that is, to lie about the actual investments being made with investor money.
What about insurance companies? How do they fit into the picture? And how can we avoid another AIG, which issued $450 billion in insurance policies, called credit default swaps, and spent these premiums on risky investments, holding nothing in reserve against policy claims. Here we would need tight regulation by the FFA strictly limiting what insurers can insure and including aggregate risk clauses spelling out clearly how payouts will be limited in case insurance claims exceed expected levels. We would also need the FFA, not private-sector companies whose own incentives structures may or may not be perverse, to rate the insurance companies.
Limited-purpose banking may sound radical, but it's not. Fidelity Investments, TIAA-CREF and other mutual fund companies have been operating as limited-purpose banks for decades and, no surprise, they aren't going under. While banks take on zero risk under limited purpose banking, this new system wouldn't limit the public's investment opportunities. Today's mutual funds companies offer some 10,000 different products to choose from. Any of us can invest in junk-bond funds, blue-chip stock funds, real estate investment trusts, emerging-market equity funds, you name it. And we can invest directly, as well, not just by buying into a mutual fund. We can still gamble and lose our shirts if we want to; limited-liability banking does not try to spite human nature, close the casino, end the American penchant for rolling the dice, or subvert any other facet of our liberty to spend our money how we choose. It just eliminates the ability of banks and other financial institutions to act irresponsibly with other people's money.
Since all financial institutions "selling" securities would be mutual funds capable of issuing checking accounts, with 100 percent reserves, we'd have one set of regulations that apply to all financial corporations. Hence, this plan envisions no return to the old Glass-Steagall provision that limited the types of assets in which banks can invest, introduced in the 1930s but abandoned in the 1990s. To repeat, under limited-purpose banking banks don't invest; they intermediate and nothing else.
Apart from running the FFA, limited-purpose banking costs nothing. It doesn't waste huge sums relieving banks of their past mistakes. It restores trust via the only possible source available right now - the government - and it gets credit flowing through financial intermediaries because lenders (purchasers of mutual funds of loans) will know what they are buying. It is a cheaper solution than all the others being contemplated, and it is vastly cheaper than failing to solve the problem, which is precisely what these other "solutions" will accomplish.
Trust is a precious and ultimately fragile commodity, particularly the impersonal social trust bound up in institutions. Wall Street's masters of the universe squandered our trust unconscionably, and Jimmy Stewart is not coming back from Bedford Falls to save the day. We need a new system that takes the con out of financial services once and for all. We need limited-purpose banking.
