Partial Effective Price (PEP)

Partial Effective Price (PEP) describes the price that effectively applies to a specific portion of a total position when quantities are fixed at different times or through different instruments.

In commodity markets, positions are rarely established at a single price. Instead, prices emerge from a combination of spot purchases, hedges, and open exposure. The partial effective price makes this fragmentation explicit by showing which price applies to which share of the total volume.

Understanding Partial Effective Pricing

Partial effective pricing helps to clarify how much of a position is already price-fixed and how much remains exposed to future market movements. Rather than relying on a single average price, it reflects the actual structure of costs and risk.

Why Partial Effective Prices Matter

Interpreting partial effective prices allows organizations to better assess incremental risk. When prices move, only the unfixed portion of the position is affected, while previously fixed volumes remain unchanged.
