In 1634, in what later came o be known as "tulipmania", tulip bulbs were traded in a special marketplace in Amsterdam, the scene of a rabid speculative frenzy. Some rare black tulip bulbs changed hands for the price of a big mansion house. For four feverish years it seemed like the craze would last forever. But the bubble burst in 1637. In a matter of a few days, the price of tulip bulbs was slashed by 96%! Uniquely, tulipmania was not an organized scam with an identifiable group of movers and shakers, which controlled and directed it. Nor has anyone made explicit promises to investors regarding guaranteed future profits. The hysteria was evenly distributed and fed on itself. Subsequent investment fiddles were different, though. Modern dodges entangle a large number of victims. Their size and all-pervasiveness sometimes threaten the national economy and the very fabric of society and incur grave political and social costs. There are two types of bubbles. Asset bubbles of the first type are run or fanned by financial intermediaries such as banks or brokerage houses. They consist of "pumping" the price of an asset or an asset class. The assets concerned can be shares, currencies, other securities and financial instruments - or even savings accounts. To promise unearthly yields on one's savings is to artificially inflate the "price", or the "value" of one's savings account. More than one fifth of the population of 1983 Israel were involved in a banking scandal of Albanian proportions. It was a classic pyramid scheme. All the banks, bar one, promised to gullible investors ever increasing returns on the banks' own publicly-traded shares. These explicit and incredible promises were included in prospectuses of the banks' public offerings and won the implicit acquiescence and collaboration of successive Israeli governments. The banks used deposits, their capital, retained earnings and funds illegally borrowed through shady offshore subsidiaries to try to keep their impossible and unhealthy promises. Everyone knew what was going on and everyone was involved. It lasted 7 years. The prices of some shares increased by 1-2 percent daily. On October 6, 1983, the entire banking sector of Israel crumbled. Faced with ominously mounting civil unrest, the government was forced to compensate shareholders. It offered them an elaborate share buyback plan over 9 years. The cost of this plan was pegged at $6 billion - almost 15 percent of Israel's annual GDP. The indirect damage remains unknown. Avaricious and susceptible investors are lured into investment swindles by the promise of impossibly high profits or interest payments.
