To make an efficient hedge, the risk must be properly defined. Energy producers and end users have supply chain price risk. Either the production is at risk of falling prices or the use is at risk of rising prices. Castlebridge analyzes the supply chain by quantifying the input vs. output stream over time. We then match the risk in distinct time and price tranches to create an efficient and conservative hedge. The best hedge may be found in either the cash, OTC, or exchange traded market. Castlebridge engineers the best hedge and executes it in the most efficient market.
