Her pain has been felt throughout Asia this week by retail investors who thought they were buying the dip but instead got crushed by oil’s unprecedented collapse below zero. From Beijing to Seoul to Mumbai, the oil-tracking funds that offered cheap entry for the layperson suffered substantial losses.

Oil prices go negative – and Washington is paralysed over what to do

“I’m not an oil professional, it’s natural that I don’t know the concept of negative pricing and rolling,” Dong, 31, said in a phone interview. “Oil should at least have some kind of value. There’s no way it should fall into sub-zero value.”

Investors are being rattled because of a rarely used but very important detail in the WTI contract: anyone holding futures after they expire could be forced to take delivery of crude in the US oil hub of Cushing, Oklahoma. For the May contract, that expiration happened Tuesday night.

Storage tanks there are nearing capacity as fuel demand is decimated by widespread lockdown measures to slow the spread of the coronavirus. With fewer people able to buy crude and store it, liquidity in near-term contracts dries up, making squeezes like Monday’s more likely.

Dong’s lucky she cashed out when she did. Most of her investment was in a Bank of China product pegged to May WTI futures. That means her money was tied up in a contract that fell to as low as minus US$40.32 a barrel just hours after she cut her losses.

Oil rebounds from record wipeout with prices edging above zero

The chaos played out elsewhere in Asia this week. In South Korea, a brokerage saw its trading system freeze when prices went negative, leaving customers helpless as they watched losses pile up. Exotic structured notes in the country tied to oil were also at risk of massive losses. A Hong Kong exchange-traded oil fund with more than US$500 million in assets as of Monday plummeted 46 per cent Wednesday after it decided to sell its June contracts and repurchase more-expensive September derivatives.

Wall Street takes worst tumble in 3 weeks as oil crash adds to virus fears

The Hong Kong fund, Samsung S&P GSCI Crude Oil ER Futures ETF, warned that if it held onto June contracts the net asset value may drop to zero and investors may suffer “a total loss” in a “worst case scenario.”

In India, clients of Motilal Oswal Financial Services had outstanding dues of about US$10 million, it said in an email, from losses on their WTI-linked oil futures on the Multi Commodity Exchange of India.

“The stand taken by the exchange is incorrect, illogical and unprecedented from the overall commodity derivative market ecosystem perspective,” it said, referring to allowing negative settlement prices. “We hope the regulator will also look into this issue in the right perspective.”

The exchange, known as MCX, wasn’t immediately able to comment.

No free oil for China after key US benchmark dropped below zero

The United States Oil Fund, the biggest ETF tracking crude prices, took a series of unusual actions after losing a third of its value in two days. It had to suspend the issuance of new shares, an action that could leave it untethered from prices it’s supposed to track. Interactive Brokers Group Inc. on Tuesday announced an $88 million provisionary loss due to several customers who held long positions in the May WTI contract when it expired, triggering losses that outstripped the equity in their accounts.

Retail Inflows

Given the difficulty and costs of storing oil, even in normal times, investors typically never keep positions into expiration, Goldman Sachs said in a note. The surge of inflows to oil in recent weeks suggest that retail investors were likely still long May WTI contracts into this week, the bank said.

For Dong, who studied alongside oil industry professionals in her MBA programme, the experience has soured her on future investments in crude.

“If the underlying contract keeps rolling, then it’s a short-term product. But I’m a long-term value investor,” she said. “I discovered from this incident that oil wealth products are not my thing.”
