How Argus assesses propylene oxide and derivatives markets
- Physical market prices
Argus publishes physical market prices in the open market, using the trading period deemed most appropriate in consultation with industry to capture market liquidity.
- Broad market data collection
Price assessments are informed by data from producers, consumers and intermediaries, gathered by reporters through proactive polling via telephone, instant messenger and email.
- Transaction verification
Reporters verify price, volume, specifications, location basis and counterparty for all transactions, applying primary and secondary tests to identify and scrutinise outlying or anomalous data.
- Judgement-based assessment
Where transaction data are insufficient, Argus assesses market value using bids, offers, spread trades, exchange trades and fundamental supply and demand information alongside validated transactions.
- Dynamic pricing models
US and European propylene oxide contract prices are calculated monthly using a dynamic formula incorporating propylene feedstock costs, freight, energy costs and a periodically reviewed adder.
