Forced pivot from Keynesian demand management to monetary-target plus expenditure control in response to sterling crisis. After the 1975 inflation peak (~24% headline RPI) and successive sterling slides, the government sought a $3.9bn IMF standby in September 1976 — the largest IMF drawing to that date. Letter of Intent (15 December 1976) committed the UK to Domestic Credit Expansion targets (£9bn 1976/77, £7.7bn 1977/78), PSBR ceiling of £8.7bn 1977/78 falling to £8.6bn 1978/79, and £2.5bn cumulative public-expenditure cuts over two years. Callaghan's September 1976 Labour Conference speech ('you cannot now, if you ever could, spend your way out of a recession... by cutting taxes and boosting Government spending') signalled the doctrinal shift. Sterling stabilised; DCE and M3 targets met; but the 1978-79 Winter of Discontent (public-sector pay cap breaking under union pressure) ended the government. In framework terms the movement marks the end of the 1945 post-war consensus: the tools of fiscal stabilisation were subordinated to external balance and price stability.
Policy-content fingerprint — how the framework codes this movement on its axes
Pre-1996 sample extension. Coded as a distinct movement from Thatcherism: monetary-target adoption preceded the 1979 election, but labour-market and privatisation content did not.
