Meaning
Temporal gaps in cost adjustments occur when a pricing model relies on historical averages rather than current spot rates. This formulaic lag is a standard feature of contracts that use moving averages to smooth out volatility.
Calculation Timing
Indexing periods often look at the preceding month or quarter to determine the next billing cycle. Because of this, formulaic lag ensures that the manufacturer is always buying materials at today’s price but selling the finished product based on yesterday’s data. This gap can create a temporary squeeze on working capital.
Price Friction
Buyers and sellers often experience tension when the contract price remains disconnected from the visible market reality. If the formulaic lag lasts for ninety days, a buyer might see a crash in oil prices but still pay a high shipping surcharge for three months. Clear communication about the smoothing mechanism helps manage expectations.
Market Alignment
Long-term stability in the supply chain requires a mechanism to eventually bring the contract back in line with actual costs. By the time the formulaic lag catches up, the total amount paid usually balances out against the average spot price over the full year. Both parties accept this temporary misalignment as the price for predictable cash flow.
