1. 01۱۹۷۶Credit squeeze collapses construction boomقوت ارتباط

   A sharp rise in inflation combined with a Central Bank credit squeeze ends the oil-boom-fueled construction and building boom that had drawn international contractors to Iran since the early 1970s, sharply slowing investment and GDP growth.

   چرایی این پیوند: Primary aluminum ingot production, which had risen from 33,700 tonnes (1973) to a peak of 51,000 (1975), fell to 30,600 (1976, -40.0%) and 21,100 (1977, -31.0% further, -58.6% cumulative from the 1975 peak) -- aluminum being a heavily construction- and durable-goods-linked industrial metal, this decline tracks the 1976 credit squeeze's ending of the oil-boom construction boom almost exactly.

   ملاحظه: Global aluminum prices and Iran's own alumina/energy-input supply arrangements (the Iranian smelter relied on imported alumina) could independently affect output in ways this project's data cannot separate from the domestic credit-squeeze channel.

2. 02۱۹۷۹Islamic Revolutionقوت ارتباط

   Mohammad Reza Shah's government falls; the Islamic Republic is proclaimed under Ayatollah Khomeini on 1 April 1979.

   چرایی این پیوند: After a partial 1978 recovery to 25,500 tonnes, production resumed its collapse to 14,000 (1979, -45.1%) and just 10,000 by 1980 (-60.8% cumulative from 1978, -80.4% from the 1975 peak) as the revolution and its immediate aftermath compounded the industrial disruption already underway since 1976.

   ملاحظه: This chart's data ends in 1980, so it cannot show whether the subsequent Iran-Iraq War deepened or began to reverse this trend; the 1976 credit squeeze and 1979 revolution are two distinct, sequential shocks to the same declining trend, not a single event, and their individual contributions cannot be separated from production data alone.
