IOCs

International Oil Companies (IOCs) are large, multinational energy firms engaged in exploration, production, refining, and marketing of oil and gas. Examples include major integrated companies operating across multiple regions.

IOCs play a central role in global energy supply, capital investment, and technology deployment. Their production decisions, project approvals, and trading activities can materially influence market balances.

In trading, IOCs are often active participants in physical markets, selling production, optimising refinery runs, and arbitraging regional price differences. They also hedge exposures using derivatives to stabilise cash flows.

Example: an IOC may produce crude in one region, refine it in another, and sell products globally, using trading desks to manage price and logistical risk. Their scale and balance sheets give them significant influence in energy markets.
