U.S. LNG exporter Cheniere Energy Inc. (AMEX: LNG) has inked a 15-year, 1 million tonne per annum (mtpa) sales deal with Swiss commodity trader Trafigura Group Pte. Ltd., a sign of how the sector's middlemen are expanding their market share.

LNG deliveries to Trafigura, one of the biggest independent traders of the fuel, will begin in 2019, Cheniere said in a statement on Jan. 16.

Swiss trade houses grabbed a $10 billion share of the rapidly growing LNG business last year, handling roughly 8.5% of all supply.

They have benefited from the emergence of new LNG importing countries such as Egypt and Pakistan with rapidly growing energy needs and high credit risks, acting as a buffer for risk-averse suppliers and producers unwilling to take direct exposure.

Trafigura, Vitol, Gunvor Group Ltd. and Glencore Plc are all used to dealing with politically complex markets. As many countries are hungry for gas as a cleaner alternative to oil and coal for generating power, traders are expected to keep growing their market share.

Some are moving beyond trading, seeking stakes in LNG production and leasing capacity in facilities such as floating import terminals, which are cheaper than those on dry land.

Gunvor was the first independent trader to gain access to long-term LNG supply in a deal with Russia's new Yamal plant in the Arctic.

Last year it also agreed to buy all the output from Africa's first deepwater floating LNG plant in Equatorial Guinea.

Glencore in September said it agreed to a long-term deal for LNG supply from Angola.

Trafigura's agreement with Cheniere Marketing would help the Houston-based company to fund its expansion plans, CEO Jack Fusco said.

In addition to the four operating 0.7-billion cubic feet per day (Bcf/d), or 4.5-mtpa, liquefaction trains at its Sabine Pass facility in Louisiana, Cheniere has three 0.7-Bcf/d units under construction at its Corpus Christi export facility in Texas and Sabine Pass.

In addition, the company has other units that are fully permitted at Corpus Christi and Sabine Pass that it plans to build once it gets enough financial commitments.

One Bcf/d can fuel about five million U.S. homes.

The company has been expanding its presence in Asia to benefit from the rising demand for LNG from the region.

According to the sale-purchase agreement, the purchase price for LNG is indexed to the monthly Henry Hub benchmark price, plus a fee.
