For a generation, inventory was treated as inefficiency. The best-run manufacturers were lean, fast-moving and lightly stocked. Raw materials arrived when needed, not before.
That model has not disappeared. But it is being quietly rewritten.
Procurement teams are again buying materials before they need them — not because demand is booming, but because supply risk has become harder to price. Tariffs, shipping disruption, energy volatility and geopolitical uncertainty have made “just in time” feel increasingly like “just in case it arrives”.
The result is a return of stockpiling, but in a more expensive form.
Companies are not simply building inventory because they want more physical material. They are doing it because they need protection against a world in which a port closure, policy announcement or energy shock can change delivered costs overnight.
The problem is that stockpiling is a blunt hedge. It protects against shortages, but it creates exposure elsewhere. If prices fall, manufacturers are left holding expensive material in a cheaper market. If customers demand price reductions before inventory turns over, margins are squeezed. If interest rates remain high, the working capital cost becomes harder to justify.
This is the new procurement dilemma: the cost of being short has risen, but so has the cost of being long.
The behaviour is most visible in markets where substitution is difficult aluminium, copper, chemicals, fertiliser inputs, packaging materials and battery supply chains. These are not commodities that manufacturers can easily replace at short notice.
Stockpiling may be rational. But it is also a sign that companies lack better ways to manage price risk.
Relying on stockpiling to manage raw material price risk? ChAI Protect helps businesses reduce the financial impact of adverse commodity price movements, giving procurement and finance teams greater confidence without relying solely on physical inventory buffers.
