Making Money (8): Virtual Money

When money was tangible you had to guard it, now that it's mostly virtual you have to verify it. Hardly anybody can, and that's a problem.

When money and wealth were wampums, precious metals, and paper currency, these physical objects required physical protection. It was all a big nuisance, with six-guns on the belt, bank vaults, and appraisers of one sort or another. But now that wealth is merely a bookkeeping entry on someone's computer, things may be even more nuisance because verification is almost beyond us. Counterfeiting of the computer variety must be left to institutions to detect or deflect, causing them to introduce firewalls of various sorts that also block legitimate inspection by customers. "Trust but verify" doesn't work so well in this environment. Let's use a personal example, slightly fictionalized to protect the innocent.

Several software products now exist to download transaction information automatically from various institutional sources to a customer's home computer; they are either free or cost a nominal amount, and are quite "user-friendly". In my case, however, the reports they generated were quite significantly at variance from the monthly reports which were issued directly by my counterparties. Dear Sirs, Please explain.

What I soon discovered was that everyone blamed someone else, and everyone blamed me for bothering them. Quite obviously, I had little understanding of these specialized accounting niceties, and quite obviously I had too much spare time on my hands. Telephone help desks, often located in India, will not give out telephone numbers for incoming calls and are programmed to check the size of your account before placing you in a call-back queue. The first call is usually taken by a trainee whose job it is to screen out the silliest sort of help request, and then to refer to a supervisor if things rise in complexity. Supervisors have supervisors. That's if you are lucky. More commonly, the tedious software business has been farmed out to a vendor, and the contracting agency has neither the necessary understanding of the issue nor any ability to fix it. From the sound of it, the vendor often gives the contracting agency the same sort of isolation treatment that they would give a customer if he could find their telephone number. And guess what. At the end of the day, one of those high-handed defensive linemen -- turns out to have been at fault.

Let's explain one problem. On the surface, we were talking about a $40,000 difference in account balances; one may have been correct, but a second one must have been wrong. That rises to lawsuit level, so the matter got intensive study. It turns out the stockbroker had misinterpreted instructions for a "sweep-account" system. When a stock in your portfolio pays a dividend, the amount of the dividend is subtracted from that stock's line item and added to the line item of your money-market fund. That's fine, but there is one exception. When the money market fund itself pays a dividend, subtracting that dividend cancels out the addition, and the dividend essentially disappears from your net worth. Was this intentional? Certainly not; no one could stay in business doing that. It's not even a highly stupid error, since you can easily see yourself making the same oversight of the one implicit exception to the rule of sweep accounting. Because of this "bug" in the program involved one institution making a mistake and transmitting it to a second institution, the systematic error did not unbalance any books, until it reached mine. But since I did not detect the error for five months, there must be dozens, hundreds, maybe thousands of customers who did not detect it. Ouch. Do the math yourself to judge whether this was a serious error.

This illustration, only one of several on my personal report, leads to at least two larger principles. The first is that the transformation of money from tangible to virtual has occurred so rapidly that bullet-proof safeguards have not had time to emerge. After a century of use, most people cannot balance their checkbooks, but enough people can balance them so that systematic errors are not likely to slip past. When enough people with home computers repeatedly test the internal complexities of their virtual money accounts, confidence will develop that the system is probably working. Confidence is an important matter; it is possible to imagine quite a bank panic if the public suddenly got the idea that virtual money is maybe a mere vapor. In fact, the securitized credit panic of 2007 is a little like that. With a few new regulations and a lot of computer programming it surely will be possible to know who owns how many bum mortgages. That innovative mortgage system got ahead of its tracking verification, and we now just have to hope nothing serious happens before that gets fixed.

The second important lesson is that our health insurance system has a similar problem of far greater size and complexity. We are here talking about at least ten percent of Gross Domestic Product, in which one daily unit of measurement is in truckloads of insurance claims forms. Stocks and bonds are admittedly complicated but compared with thousands of different diagnoses, drugs, procedures, and hospitals -- verifying financial transactions is trivial compared with measuring medical ones. With a twenty billion dollar budget and ten years of lead time, we might have a shot at it. Except for the fact that during the ten-year interval, medical care will have changed so much, you will have to start over on the project.
