Research shows semiconductor chip lead times slipped to 20.2 weeks in July, up by eight days over June, which was already the longest wait time since 2017
The amount of time it's taking for chip-starved companies to get orders filled has stretched to more than 20 weeks …
Context & Ripple Effects
Lead times had been climbing all year: by April they had expanded for four straight months to 17 weeks, after a March survey already showed individual suppliers like Broadcom stretching from 12.2 weeks to 22.2 weeks amid industry-wide bottlenecks.
July's 20.2-week reading pushes waits past anything seen since 2017 and confirms the shortage is deepening rather than clearing, turning delivery-time data into the key stress gauge for every downstream electronics buyer.
First-order effects
- Chip buyers now have to commit more than five months ahead, forcing automakers and device makers to lock orders before knowing final demand.
- Suppliers with the most constrained product lines — Broadcom's earlier 22.2-week lead time being the extreme case — gain pricing leverage over customers who cannot switch sources quickly.
Second-order effects
- Extended lead times push customers toward speculative over-ordering to secure allocation, which further inflates measured demand and makes the queue self-reinforcing.
- Capacity-expansion announcements collide with their own supply chain: leading chip-tool makers were warning clients of waits up to 18 months for key equipment, meaning the fix for today's shortage is itself rationed.
Third-order effects
- Because fab capacity takes years to add while demand signals are distorted by double-ordering, the industry risks overshoot — building capacity that arrives after the shortage has peaked, setting up the next downcycle.
- Persistently long lead times accelerate a shift away from spot buying toward multi-year supply agreements and direct customer-foundry deals like TSMC's record-sales run, reshaping how chips are priced and allocated.
The trend: Semiconductor supply is moving from just-in-time spot purchasing toward contracted, capacity-committed relationships, with lead times serving as the cycle's leading indicator.
