Semiconductor lead times increased to 17 weeks in April, marking the fourth consecutive month of “sizable” expansion, according to research from trading group
- Lead times have climbed to the highest level since 2017 — Automakers are expected to lose out on $110 billion in sales
Context & Ripple Effects
This April reading is the middle chapter of a shortage arc that opened in January, when Volkswagen, Daimler, GM and Renault were already cutting output over chip supply — Volkswagen alone planned 100K fewer cars in Q1. Four consecutive months of 'sizable' lead-time expansion since then pushed waits to their highest level since 2017.
What makes the 17-week figure significant is where it sits on the curve the related coverage traces: waits kept stretching through July (20.2 weeks) to a December peak of 25.8 weeks even as TSMC posted record sales, before the cycle turned and chipmakers ended 2022 with swelling inventories instead.
First-order effects
- Automakers are the immediate casualties: the research pegs lost sales at $110 billion, and the shortfall deepened through the year until production cuts reached 7.7 million vehicles globally per the September revision (7.7M fewer cars, $210B in lost sales).
- Chip buyers across industries face a planning problem — at 17 weeks and rising, orders placed today arrive well past typical quarterly planning horizons, forcing earlier and larger commitments.
Second-order effects
- The widening gap between demand and delivery pushes automakers toward long-term supply contracts and direct commitments to foundries like TSMC, whose record sales through the peak show where the pricing power sat during the shortage.
- Extended lead times amplify the bullwhip effect downstream: buyers double-order against uncertain deliveries, which is precisely the behavior that produced the inventory glut once demand cooled.
Third-order effects
- The full arc — 17 weeks climbing to 25.8, then falling lead times and swollen stockpiles by end-2022 — illustrates the industry's structural capacity lag: fab investment decisions made in shortage arrive into surplus, making the contracted cycle self-reinforcing in both directions.
The trend: Semiconductor lead times are tracing the boom leg of the industry's contracted cycle, with capacity lag all but guaranteeing that today's shortage becomes tomorrow's surplus.
