Inventory risk

Inventory risk is the exposure to financial loss from holding physical oil or refined product stocks when market prices move unfavourably. In energy markets, inventory is often held to meet contractual obligations, balance logistics, or capture arbitrage opportunities, but it creates continuous price exposure.

Because oil prices can move sharply due to geopolitical events, outages, or macroeconomic shifts, inventory values can change rapidly. This risk is amplified when inventories are large, held for long periods, or financed with borrowed funds.

Inventory risk is managed through hedging, typically using futures or swaps linked to the relevant benchmark. However, hedging may be imperfect due to basis risk, quality differences, or timing mismatches.

Example: a trader holding gasoline inventory may hedge using ICE gasoil futures, accepting basis risk between the product and the hedge. If demand weakens unexpectedly, both prices and margins may fall. Effective inventory risk management balances physical optimisation with financial discipline.
