Supply Chain Inventory Carrying Cost Avalanche.

Diagnoses why giant retailers go bankrupt when macroeconomic lead-times spike, forcing them to store massive buffers of depreciating physical inventory in expensive US warehouses.

## The 'Just-in-Time' Dependency

For decades, companies like Toyota and Apple perfected "Just-In-Time" (JIT) manufacturing. Parts arrived at the factory exactly 6 hours before they were assembled, meaning companies held zero physical inventory. When macro shocks hit (like pandemics or canal blockages), lead times spike from 30 days to 180 days. Companies panic and over-order, filling giant warehouses. Then, the Carrying Costs destroy them.

### FAQ

**Q: Why doesn't Target just keep 3 years of inventory in a warehouse like a squirrel?**
A: If a retailer holds $15 Million of TVs in a warehouse for a year, they don't just sit there for free. The company is paying the bank 7.5% interest on the loan used to buy the TVs. They are paying 6% in warehouse rent and insurance. And because it's technology, the TVs lose 8% of their value to obsolescence as better TVs are released by competitors. Holding physical assets in a warehouse legally costs a company ~21% of the asset's value every single year. Inventory is a liability, not an asset.
