Tariffs often take the blame for rising costs, but they’re only one of several forces disrupting margins. Commodity prices fluctuate, freight rates swing, and supplier lead times shift with little warning. Even when markets calm, energy costs, exchange rates, and global disruptions can quickly erode predictability.
For purchasing and supply chain teams, volatility has become a constant, not an event. And while it’s tempting to focus on forecasting where costs are headed, the real question is: how much risk are you carrying if they move against you?
That’s where inventory comes in.
Every extra day of stock you hold is a position you’ve taken on the future. If costs rise, your current inventory suddenly looks cheap. If they fall, you’re left holding a product that’s instantly worth less than you paid. Either way, inventory amplifies the impact of volatility, for better or worse.
Inventory is price risk. The challenge isn’t predicting what will happen next; it’s managing your exposure when it does.
Six major factors drive most cost movement today:
No company can consistently predict how these will behave. Studies of procurement teams show that even experienced buyers rarely call cost direction correctly over a six-month window.
If prediction isn’t reliable, what is? Visibility and control. That means understanding how much exposure your business carries, and using inventory management as the mechanism to contain it.
Inventory converts external volatility into internal risk. When costs are rising, holding inventory on hand is a winning bet. But if prices fall, it can quickly turn into overvalued stock and stranded capital.
The illusion of safety in holding “a little extra” inventory hides real risk. Having more days on hand means increased exposure to cost fluctuations, aging, obsolescence, and financing costs. Less coverage, on the other hand, increases vulnerability to service disruptions if suppliers delay or costs spike unexpectedly.
The key is balance — knowing where risk is worth holding and where it isn’t.
The goal isn’t to eliminate inventory; it’s to manage it with the same discipline applied to financial risk.
Visibility is the foundation of reasonable control. Teams that understand the true landed cost of their products, including tariffs, freight, insurance, and handling, are better positioned to make informed stocking and purchasing decisions.
Accountability complements visibility. Tracking supplier lead-time performance, delivery reliability, and responsiveness allows teams to align their inventory posture with supplier behavior. A supplier that consistently misses lead times deserves higher coverage. One that’s reliable does not.
The combination of cost visibility and supplier accountability allows teams to replace reactive decisions with structured, evidence-based adjustments.
Managing cost volatility isn’t about outsmarting markets, it’s about designing resilience into daily operations. When inventory is treated as both exposure and control, it becomes a strategic buffer against uncertainty rather than a passive outcome of it.

Cost volatility isn’t optional — but exposure is. With disciplined inventory practices, volatility becomes something you manage, not something that manages you.
