Excluding memory, correlation coefficient expected to reach a very high level of 0.94 in the 2018-2023 timeframe.

In its soon to be released Mid-Year Update to The McClean Report 2019, IC Insights forecasts that the 2018-2023 global GDP and IC market correlation coefficient will reach 0.88 (0.94 when excluding memory), up from 0.87 in the 2010-2018 timeperiod.  IC Insights depicts the increasingly close correlation between worldwide GDP growth and IC market growth through 2018, as well as its forecast through 2023, in Figure 1.

From 2010-2018, the correlation coefficient between worldwide GDP growth and IC market growth was 0.87 (0.92 excluding memory), a strong figure given that a perfect positive correlation is 1.0.  In the three decades previous to this timeperiod, the correlation coefficient ranged from a relatively weak 0.63 in the early 2000s to a negative correlation (i.e., essentially no correlation) of -0.10 in the 1990s.

IC Insights believes that the increasing number of mergers and acquisitions, leading to fewer major IC manufacturers and suppliers, is one of major changes in the supply base that illustrate the maturing of the industry and helping foster a closer correlation between worldwide GDP growth and IC market growth.
