People know that they are likelier to lose all or part of their money as time passes. But they convince themselves that they can outwit the organizers of the pyramid, that their withdrawals of profits or interest payments prior to the inevitable collapse will more than amply compensate them for the loss of their money. Many believe that they will succeed to accurately time the extraction of their original investment based on - mostly useless and superstitious - "warning signs".
While the speculative rash lasts, a host of pundits, analysts, and scholars aim to justify it. The "new economy" is exempt from "old rules and archaic modes of thinking". Productivity has surged and established a steeper, but sustainable, trend line. Information technology is as revolutionary as electricity. No, more than electricity. Stock valuations are reasonable. The Dow is on its way to 33,000. People want to believe these "objective, disinterested analyses" from "experts".
Investments by households are only one of the engines of this first kind of asset bubbles. A lot of the money that pours into pyramid schemes and stock exchange booms is laundered, the fruits of illicit pursuits. The laundering of tax-evaded money or the proceeds of criminal activities, mainly drugs, is effected through regular banking channels. The money changes ownership a few times to obscure its trail and the identities of the true owners.
Many offshore banks manage shady investment ploys.
They maintain two sets of books. The "public" or "cooked" set is made available to the authorities - the tax administration, bank supervision, deposit insurance, law enforcement agencies, and securities and exchange commission. The true record is kept in the second, inaccessible, set of files.
This second set of accounts reflects reality: who deposited how much, when and subject to which conditions - and who borrowed what, when and subject to what terms.
These arrangements are so stealthy and convoluted that sometimes even the shareholders of the bank lose track of its activities and misapprehend its real situation.
Unscrupulous management and staff sometimes take advantage of the situation. Embezzlement, abuse of authority, mysterious trades, misuse of funds are more widespread than acknowledged.
The thunderous disintegration of the Bank for Credit and Commerce International (BCCI) in London in 1991 revealed that, for the better part of a decade, the executives and employees of this penumbral institution were busy stealing and misappropriating $10 billion. The Bank of England's supervision department failed to spot the rot on time. Depositors were - partially - compensated by the main shareholder of the bank, an Arab sheikh. The story repeated itself with Nick Leeson and his unauthorized disastrous trades which brought down the venerable and veteran Barings Bank in 1995.
The combination of black money, shoddy financial controls, shady bank accounts and shredded documents renders a true account of the cash flows and damages in such cases all but impossible. There is no telling what were the contributions of drug barons, American off-shore corporations, or European and Japanese tax-evaders - channeled precisely through such institutions - to the stratospheric rise in Wall-Street in the last few years.
