Why is there a wire shortage?
Shortages of raw materials and manufacturer capacity issues have also contributed to the shortage. Large semiconductor companies have been merging, resulting in the cutting out of low-margin lines and the elimination of overlapping production. This has placed increasing strain on the electrical component supply chain.
