Thatcher was keen to remove the rules and regulations that she believed stifled innovation and competitiveness
The first example of this was the removal of exchange controls in October 1979; before 1979 there were limits to how many pounds' people could convert into foreign currencies and spend abroad
The end of exchange controls fuelled greater overseas investment (which returned profits to Britain) but also led to a huge increase in consumer spending on foreign goods, which drained wealth from Britain
The most significant example of deregulation was the 'Big Band' of October1986
Big Bang relaxed the rules on the ownership and trading operation of banks, resulting in the massive growth in financial services
The City of London rapidly grew to become one of the major financial centres of the world as financial institutions took advantage of the more relaxed rules to offer riskier financial products that returned huge profits
In the longer term, deregulation enabled unscrupulous individuals to make a lot of money in an unsustainable fashion; this culture, not tackled by New Labour after 1997, led to the 2008 financial crisis
British people became more used to borrowing to pay for consumer goods
The 'Big Bang' meant that a great deal of government regulation on the financial industry was scrapped; this modernised the stock market and allowed banks to take more risks with their lending and investments
The 'Big Bang' had several effects on private individuals:
unregulated finance led to the rise in private household debt, which stood at £16 billion in 1980 and increased to £47 billion in 1989
easier access to mortgages meant that mortgage debt rose from £43 billion to £235 billion
by 2003, personal debt, including mortgages, stood at £1.3 trillion - by far the highest in Europe
While banks made huge profits, a 2003Financial Services Authority report estimated that 6 million families, around 20% of the total, faced problems with debt
The rise of credit cards also contributed to the problem of debt
The first credit card was launched in June1996
By 1980 there were 10 million credit cards in Britain
By 1990 the amount of credit cards had risen to 27 million
In 1986 the Conservative govt under Thatcher introduced a package of new rules relaxing the regulation on the LSE
The phrase Big Bang, is used in reference to the sudden deregulation of financial markets, effected by Thatcher in 1986
The new legislation on LSE
scrapped fixed commission rates, arguably making the exchange more competitive in a global market
paved the way for integrated investment banks by getting rid of the barrier between stockbrokers and stock jobbers
abolished rules barring foreign companies from buying City firms
Created a modernised and more efficient market by swapping exchange floor trading for screen-based computer trading
Abolishing rules barring foreign companies from buying City firms meant that 65% of the Citys's workforce had non-British employers in 2011
While it can be argued that the Big Bang, helped give Britain a competitive edge in the global economic market it also allowed for the risk of integrated investment bank
Many of the integrated investment banks faced a massive conflict of interest since they both advise companies on deals and market financial problems to investors
These reforms along with easy credit and the privatisation of public companies by Thatcher's government led to a huge boom in the UK and established the age of consumerism
