Experts say sourcing chips has turned almost into a lottery amid the global chip shortage, as wait times have ballooned to 22 weeks as of October
Nearly a year into the crisis, some customers are finding it is taking months more than expected to get needed parts
Context & Ripple Effects
The shortage's lead-time curve has been climbing all year: Bloomberg data showed waits at 20.2 weeks in July, already the longest since 2017, after Broadcom's lead times had earlier stretched from 12.2 weeks in February 2020 to 22.2 weeks. By October, per the Wall Street Journal, the average reached 22 weeks — and buyers describe allocation as close to a lottery rather than an orderly queue.
What makes this worse than a normal cycle is that supply can't respond quickly: equipment makers were already reporting 10-12 month lead times on wire bonding machines back in April, and by spring 2022 they were warning customers of 18-month waits for key fab tools over shortages of lenses and valves.
First-order effects
- Buyers who ordered months ago are still waiting — some now face months beyond their original expected delivery — forcing product planners to hold inventory or redesign around whatever parts actually arrive.
- Suppliers gain allocation power: when capacity is oversubscribed, chips go to the largest or highest-paying customers, leaving smaller buyers effectively rationed by luck.
Second-order effects
- Customers double-order and place speculative bookings across multiple suppliers to hedge the lottery, which inflates apparent demand and makes the eventual correction sharper when lead times normalize.
- Downstream industries — autos, consumer electronics, industrial equipment — compete for the same constrained wafers, pushing component costs into end-product prices and delaying launches.
Third-order effects
- If long equipment lead times persist, new fab capacity lands years after the demand spike, extending the boom-bust rhythm of the contracted semiconductor cycle rather than damping it.
- Purchasing behavior structurally shifts toward multi-year capacity commitments and second-sourcing, because spot-market access proves unreliable precisely when it matters most.
The trend: Semiconductor procurement is shifting from just-in-time ordering toward contracted, multi-year capacity reservations as lead times stay stretched well past historical norms.
