As of June 29, China — the world’s second-largest consumer of oil after the United States — had amassed 73 million barrels of oil on 59 different ships floating at sea off the country’s northern coast, according to ClipperData, which tracks waterborne flows of crude oil in real-time. For context, that is three-quarters of the demand for the entire planet.
China’s so-called floating storage — defined as barrels of oil on vessels waiting for seven days or longer — has nearly quadrupled since the end of May, according to ClipperData. Not only is that the most on record going back to early 2015, it’s up seven-fold from the monthly average during the first quarter of 2020.
The hoarding of oil at sea is a reflection of China’s bargain-hunting during a time of extreme stress in the energy market.
“China went on a global buying binge,” said Matt Smith, director of commodity strategy at ClipperData. “There is just this deluge of crude building up offshore.”
And Smith noted that China’s onshore storage tanks are not even close to being filled.
“This is simply related to terminal congestion. They’ve got so much coming in that they can’t bring it onshore quickly enough,” he said.
$80 swing in oil prices
It was China’s purchases that helped prop up the battered oil market.
A good-sized chunk of that oil originated in Latin America.
Brazil is the leading source of oil in China’s floating storage, according to ClipperData. It takes about a month-and-a-half for crude to get shipped to China from Brazil. Much of the oil also comes from Iraq, Saudi Arabia and Nigeria.
‘Buying like crazy’
Of course, other countries similarly took advantage of the oil crash to bolster their emergency stockpiles.
“If you’re a big energy consumer, you’d be buying with two hands,” said Ryan Fitzmaurice, energy strategist at Rabobank.
But analysts said that China’s stockpiling dwarfs what other nations have done in response to cheap prices. “China is the only country that has been buying like crazy. They went out and bought the dip,” said ClipperData’s Smith.
Fleeting arbitrage opportunity
Beyond the obvious energy security advantages, China’s purchases also had enormous financial incentives.
That’s because the oil markets this spring flipped into steep “contango” — a phenomenon that occurs when investors are willing to pay far more for a commodity in the future than they would today. The situation creates an arbitrage opportunity for market players to store crude for a few months and then flip it at a later date for a tidy profit.
“Why sell it for -$40 when you can sell it a month later for $40?” Louise Dickson, oil markets analyst at Rystad Energy, wrote in an email to CNN Business.
Energy companies and investors in the spring started using ships not just for transporting oil but to store it.
That caused the rate to hire a very large crude carrier, or VLCC, which can hold 2 million barrels of crude, to more than double to $15 million for a journey from the US Gulf Coast to China in late April, according to Rystad.
“Now that the storage panic is lifted, no reason to book VLCC for storage,” Dickson said.
Of course, the risk is that China’s thirst for foreign oil will eventually be satisfied. Imports are already sitting at record highs. Floating storage is well above normal levels. And oil markets are no longer in contango.
ClipperData’s Smith said that the traffic in crude bound for China has already begun to slow.
“Just as it helped support prices the past few months,” he said, “it may do the opposite in the months ahead.”
