The option to sell December European Union carbon permits at 4 euros ($5.18) a metric ton was the most traded last week, with 8 million tons changing hands.
Four euros would be a record low for the second phase of EU carbon market, as the European Commission in Brussels is seeking to fix a glut in supply. Permits reached a four-year low of 5.99 euros a ton on April 4. The third phase begins next year and runs through 2020.
The price to buy the 4 euro put option closed yesterday at 2 euro cents a ton, after reaching a record 66 cents on January 6, according to data from the ICE Futures Europe exchange in London. The next most-traded put was at a 7 euro strike, where 2.25 million tons changed hands. Put options give the buyer the right to sell at a certain price. Calls give the option to buy.
The most commonly traded call option was at a strike of 10 euros, with 2.75 million tons changing hands, the data show.
EU carbon allowance futures for December 2012 fell 13 cents, or 1.7 percent, today to 7.70 euros a ton on ICE as of 10:32 a.m. They’ve dropped 29 percent in the past year.
