Styrene Price Assessment: Petrochemicals Price Assessments

What are our Styrene Price Assessments?

Price of Styrene

Platts Styrene assessments are the price of physical styrene monomer cargoes and barges across the globe. Platts publishes several styrene price assessments tailored to specific markets in the US Gulf, Asia in South Asia, Southeast Asia, South Korea, Taiwan and China and Europe.

Styrene monomer is one of the key aromatic hydrocarbons derived from benzene and ethylene and used in the production of polymers such as polystyrene, acrylonitrile-butadiene-styrene, styrene butadiene latex and styrene-butadiene-rubber. It is also used to make unsaturated polyester resins. It is a colourless, oil, toxic and flammable compound produced in industrial quantities from petroleum.

Globally, the styrene market is estimated to be around 31 million mt, with Asia representing the lion’s share of production capacity at 18 million mt/year or 58%, the US at 5.44 million mt/year and Europe at 7.5 million mt/year.

Platts global styrene price assessments are available in these Platts services.

How we assess the price of styrene?

Меньше информации   Platts: minus

Platts' styrene price assessments are based on robust and transparent market data that includes, but is not limited to, firm bids and offers, expressions of interest to trade and confirmed trades of styrene reported during the Market On Close process every day. This information is summarised in our daily newsletters and published in full on our real-time information service, Platts Petrochemical Alert.

Global spot price assessments reflect styrene monomer that conforms to ASTM D-2827 specifications.

The US benchmark for styrene reflects product traded on a FOB US Gulf basis, loading 3-30 days forward from the date of publication, in cents/lb. US Domestic Weekly Transaction Price is an assessment of the contract price in cents/lb basis ex-works US Gulf Coast.

The Asian benchmarks for styrene monomer are FOB Korea and CFR China, of which CFR China is the most liquid and typically most traded price basis, on a $/mt basis. Both marker assessments average the mean of product traded on the third and fourth half-month forward. China is the key importer of SM in Asia and imported 3.34 million mt of SM in 2012. South Korea is a major exporter, shipping out 1.3 million mt of SM in 2012 -- mostly to China. Another daily assessment includes CFR Taiwan, and on a weekly basis, assessed every Friday: CFR Southeast Asia, CFR Japan and CFR India.

European benchmarks for styrene reflect daily prices on a FOB Amsterdam-Rotterdam-Antwerp basis. Platts also publishes a monthly barge contract price on a FOB ARA basis, and a monthly truck contract price on a FCA Northwest Europe basis.

Platts’ styrene price assessment reflects the tradable, repeatable spot market value of the most competitive grade at 16:30.00 in London and Singapore and 1415 in the US precisely.

Platts gathers price data from a wide segment of the market, including ethanol producers and distributors as well as aromatics traders, brokers, consumers and end-users.

Evolution of Styrene – a brief history of major changes

Меньше информации   Platts: minus

In Asia Platts has been assessing styrene monomer on an FOB Korea and CFR China basis since January 2004. In June 2012 the daily CFR China marker was aligned with the FOB Korea marker to reflect the mean of the third and fourth half-month forward assessment ranges (second and third half-month forward published assessment cycle) as trading activity was increasingly focused on forward months.

In October 2013, the amount of ports used for assessing the CFR China benchmark was reduced from seven to four to reflect changing trading patterns.

Platts proposes to terminate its weekly CFR Japan assessment in April 2014 to reflect changing trading patterns.

In Europe Platts launched daily European styrene price assessments on July 1, 2004.

On March 1, 2012, Platts expanded the loading port basis for its styrene spot assessments from FOB Rotterdam basis to FOB Amsterdam-Rotterdam-Antwerp.

Effective January 1, 2014, Platts proposes to discontinue its FD Northwest Europe and FOB Rotterdam contract price assessments for styrene barges.

In the US Platts launched daily styrene prices in the US on March 4, 2002.

Platts launched a weekly US Domestic Weekly Transaction price on February 5, 2010. This assessment replaced the domestic transaction contract price for styrene, published at the close of each business week and settled retroactively.

Standard spot assessments reflect product loading 3-30 days forward from the date of publication. Platts launched an additional balance-month spot assessment on December 1, 2008, which reflects production loading during the balance of the current month.

Platts changed assessed roll dates on monthly spot styrene assessments to reflect the forward month, five calendar days prior to the end of the month on November 2009.
