Bubble of the global debt
From where does the financial bubble come? Let's look at an example of a simple scheme. John does not have money, but he wants to buy a car. John goes to the bank and takes conditionally, $ 100 credit. The money he hands to the car owner. The recipient has nothing to spend it on. And he carries $100 in the bank. The Bank holds in its safe only a part of depositors' funds. Usually, it is 10%. The rest of the money it may hand over in lending. We have $100, which belong to the seller of a car and lie in the bank. And another $90 that borrowers owe the bank. Total economy turns $ 190. Now imagine it on a global scale. People borrow money, buy houses, cars and yachts, sellers put money in banks. These actions are repeated again and again. Permanent resale of $ 100 bills in the economy turns into thousands, millions, even billions. And the more people earn money and put in the bank, the more the bank can create new loans. Money in the economy is inceasing more and more. Total debt is increasing. The financial bubble is inflating.
The South Sea Bubble
This 1720 crisis gave us the term "bubble."
The South Sea Company had a monopoly on trade with Spanish South American colonies, which was granted by the British government in exchange for taking over national war debt.
Its shares started to rise and rise on the back of its own spruiking of eye-watering South Sea riches.
It convinced the British government to allow it to assume more national debt in exchange for its shares, boosting them to £330.
A subsequent flurry of stock market speculation led to Parliament passing the "Bubble Act" in June which required all companies to receive a royal charter.
The South Sea Company received its charter, seen as a vote of confidence, and by the end of June its share price reached £1,050.
But investors lost confidence and by September that year the shares had plummeted to £175.
US joins the party with the Panic of 1792
This was the USA's first financial crisis. It was caused by a credit expansion by the newly-formed central Bank of the United States (BUS) and speculation by some dodgy bankers.
The bankers contrived to drive up the prices of US debt securities and bank stocks. Meanwhile, the BUS was lending money freely, much of which was spent on further speculation.
When the BUS ran low on hard currency, it reined in lending and markets fell 25 percent in a fortnight. The crisis led to Alexander Hamilton, the first Treasury secretary of the United States, engineering that country's first bank bailouts.
The first emerging market crisis
In 1825, the industrial revolution was in full swing and Britain was booming so cashed up investors were looking for somewhere to park their new found riches.
Foreign bonds offering attractive returns by governments in the New World caught their eye.
Newly independent nations such as Chile, Peru, Mexico and Guatemala sold bonds worth billions on the London market. British mining companies looking to exploit the Americas also saw share prices surge.
Inevitably bond prices plummeted as the shaky finances of those countries were gradually exposed. Some bonds fell by as much as 40 percent leaving Britain's banks exposed, and a bank run followed.
The Bank of England jumped in to bail out collapsing lenders and exposed firms.
Going off the rails - the first global crisis
1857 saw the first tech bubble and first global financial crisis when British investors piled into American railway firms.
The railway companies' share prices bore little relation to their earnings but investors were betting on future profits.
As US railroad firms started to fail, first US banks and lenders, then their British counterparts were left exposed.
By the end of that year £42m of British investor capital had been wiped out.
As the world's first financial hub, Britain's woes spread to other markets. Economic contagion was born.
Banks, but not banks; the "Knickerbocker" crisis
By 1907 the US had started to develop a highly decentralised banking system - its first central bank (BUS) had long since closed.
There was an explosion of new banks and less regulated trust companies at the end of the 1900s.
The trust companies started to behave like banks but didn't need to hold as much cash in reserve - 5 percent versus 25 percent.
They also offered more attractive returns to investors and so grew exponentially - as did the wider US economy.
Two rogue bankers, meanwhile, tried to corner the shares in a copper company with fraudulently-acquired money, but raw material prices fell, as did share prices in the copper company.
The Knickerbocker Trust, the third largest in the US, was caught up in the spreading crisis.
Its depositors demanded their cash, setting off a run on trust companies and then banks.
The crisis led to the US returning to a "lender of last resort" model and its third and existing central bank, the Federal Reserve, was born.
The Big Daddy crash
As the roaring 1920s came to a close, the Federal Reserve, formed 16 years earlier, was grappling with the problem of surging share prices but dropping consumer prices - should it cut or raise rates?
It raised rates in 1928 from 3.5 percent to 5 percent with disastrous results.
The move failed to cool Wall Street, but put the brakes on the far shakier real economy - industrial production plummeted.
Shares continued to make merry, hitting a high in September 1929.
This financial own goal in the US was compounded by a fraudster-originated crash on the London Stock Exchange.
A sell-off ensued and Wall Street lost 25 percent in two days and almost half its value by November of 1929.
A wave of bank failures followed that peaked in 1933 when the Federal reserve again fluffed and refused to lend to struggling banks - thousands of banks collapsed and the Great Depression began.
The first "Black Monday"
On October 19, 1987, The Dow Jones industrial average plummeted by 22.5 percent and £50 billion was wiped from the London market.
The stock price falls started in Asia and spread quickly, helped by new automated trading systems.
By the end of October, markets in Hong Kong, Australia, Spain and Canada had plunged. New Zealand's market fell 60 percent.
However this crash had few effects on the wider global economy and the Dow recovered to its previous high by 1989.
The "tigers" catch a cold
Also called the Asian Contagion this was a series of currency devaluations and asset price crashes that spread through Asian markets in 1997.
It started in Thailand as the result of the government's decision to no longer peg the Baht to the US dollar.
Currency declines spread rapidly throughout the region, in turn causing stocks to crash, and political upheaval.
The International Monetary Fund (IMF) stepped in with a $US40 billion program to stabilise the regions' economies.
The e-crash burns blue sky investors
The first crash of the digital age, in 2001, saw 78 percent of the NASDAQ's value lost as investors became over-excited by the "New Economy".
Internet start-ups were everywhere, simply adding an "e" prefix was enough to part tech-mad investors from their cash.
Just as in the rail road crisis 150 years before, company fundamentals were overlooked; bold, blue sky thinking was in.
But the dot-coms started to leak money and fold. From a peak of 457 start ups in 1999, the figure dwindled to 76 by 2001.
