Pinch point (economics)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A pinch-point is the level of inventories of a commodity or product below which consumers of that commodity or product become concerned about security of supply. When inventories are below the pinch-point, small changes in the balance of supply and demand can cause large changes in the price of the commodity or product.[1][2]

The term was suggested in 1988 by Walter Curlook (Executive Vice-President of Inco Ltd) and was first published by Raymond Goldie with Rob Maiman in 1990. In 2000 Raymond Goldie trademarked the term.
