 In an interview in 2010 Nigel Lawson said that an unintended consequence of the Big Bang was the financial crisis of 2007–2008.The trajectory taken by the UK economy from this point on is typically described as "The Lawson Boom" by analogy with the phrase "The Barber Boom" which describes an earlier period of rapid expansion under the tenure as Chancellor of Anthony Barber in the Conservative Government of Prime Minister Heath (1970 to 1974).Critics of Lawson assert that a combination of the abandonment of monetarism, the adoption of a "de facto" exchange-rate target of 3 Deutsche marks to the pound (ruling out interest-rate rises), and excessive fiscal laxity (in particular the 1988 Budget) unleashed an inflationary spiral.
