Profitable Plastics: Resin price caps—Price protection for processors, added value for suppliers


Last time, we discussed using the difference between a daily resin price (reported by PCW or TPE) and crude oil futures as a trigger for hedging forward resins purchases. The resin/oil difference (or spread) mimic the profit in producing the resin and, where commodities are concerned, profits typically normalize in a few weeks; so, spreads that mimic profits are good indicators of future price movements.

Time-to-wait saves 5 ¢/lb
A hedge is either a fixed-price financial or physical purchase or a protective purchase. (Doing nothing isn't a hedge, but it is a valid decision based on the resin/oil spread.) What is a protective purchase? For processors, it's insurance against resin prices moving higher than expectations or an acceptable level (e.g. the price required for a minimum profit margin). In crude oil and other commodities futures, insurance against higher prices are call options. For a premium (hence, insurance) related to the term and strike price of the option, a call option gives the buyer the right (not obligation) to buy a commodity at the strike price on or before the expiration of the option. Call options are preferred hedging tools of most risk managers because they limit (or cap) upside price risk for much less capital and risk than outright purchases. More important, price caps give a buyer time to wait coolly for a lower price since a price cap protects against the market moving higher while the buyer waits. In the volatile resins markets, I estimate such time-to-wait for a lower price could save processors 5 ¢/lb or more in resins costs....
