1986 Big Bang in London

On 27. October 1986, doing business through the stock market in London changed dramatically. In one huge step, known as Big Bang, trading in the Stock Exchange became a professional undertaking, as brokers began to do business through telephone and the computer instead of face-to-face. Technology changed the nature of the business in London forever. Looking back after these drastic changes had been implemented for ten years, Financial Times reporter George Graham found mixed feelings concerning Big Bang.

Some felt that it was anti-climatic, although others felt it was too sudden and should have been addressed in stages.

Elevating the Stock Exchange in London to a global level, instead of solely at the national level, certainly had a profound impact on the economy and business of trading stocks. This fundamental reform through improved technology and deregulation of the markets caused an economic boom that boosted the British economy for the next 20 years.
