Liquefied natural gas tankers are taking longer-than-usual journeys to deliver cargoes and spending more time idling at sea in a sign some traders are starting to use vessels for storage.
There may be other reasons for keeping the cargoes on the water, including logistical or weather issues, such as a monsoon in India. But with spot prices near their lowest since April 2016, sellers may be betting that they will rise as the northern hemisphere heating season approaches.
“It is saying one thing for sure: people are not too worried about shipping length,” said Jean-Christian Heintz, head of LNG broking at SCB Brokers SA in Nyon, Switzerland. “Whether they are waiting for a logistical or trading or pricing issue they do not worry about the time they spend at sea, meaning that there is no hurry in going back and loading the next cargo.”
The use of floating storage this long before the heating season is unusual because of the costs of keeping natural gas in its liquid form and indicates how trading in LNG, the fastest-expanding fossil fuel commodity, is becoming more like the bigger crude oil market. It is also partly thanks to the shale boom that transformed the US into the third-largest exporter, increased spot trading, linked prices increasingly to gas hubs rather than oil and spurred a global drive for more flexible contracts.
LNG tanker owners GasLog Ltd and Flex LNG have said that they are seeing increased inquiries from traders to use ships as floating storage. That will likely intensify in September and beyond to hold fuel before the heating season officially begins in October.
“Does it make sense to float from the end of August to the end of September?” Heintz said. “We haven’t seen that happen too often. That would be also interesting to see if we see cargoes floating for more than one month.”
Cheniere Energy Inc, the biggest US LNG exporter, said last week it sees a premium in winter prices encouraging floating storage, especially considering the premium of longer-term prices to short-term ones, known as a contango. Lower spot shipping rates also encourage the longer use of vessels.
“The market does as a whole look at the contango in the forward curve and assess if there is a floating storage possibility,” Jonathan Westby, co-managing director of Centrica Plc’s energy marketing and trading unit, said last month in an interview. “If you look at the shape of the curve now for that period of time in the autumn, there is the possibility of people taking floating storage.”
