I think he's asking why the market didn't have a better estimate of storage capacity and utilization and what changed in the estimate from yesterday to today.
I think that has to do with how people sometimes do analysis for trading. There's fundamental analysis, which looks at exactly that when attempting to determine the price to bid for a security, but then there's the bubblier "technical analysis" which really just looks at historical and current trends and attempts to divine whether buying now means you might be able to sell in the future.
I'd imagine people just assumed perfect liquidity here, and that they'd be able to sell even "at a small loss which is better than nothing," not realizing that nothing or negative (i.e. you're gonna pay somebody to take this oil off your hands or build your own tanks) is a valid outcome.
I'm going to take a stab at a possible reason the "market" didn't see this coming: Everyone expected the US to top off its strategic reserves, which so far hasn't really been happening. Now that You could be paid like $37 (west Texas crude closed at -$37.63) dollars/barrel, maybe the US will reconsider. I certainly wish I could store a few thousand barrels...
US companies don't want to stop producing oil. Couple that with the Russia/Saudi Arabia skuffle going on over oil prices, I'm not surprised. What surprises me is the absolutely rapid/rabid decline in the price. It just seems like pure insanity to me...
> Now that You could be paid like $37 (west Texas crude closed at -$37.63) dollars/barrel, maybe the US will reconsider.
Indeed, it looks like the US is reconsidering:
President Donald Trump said Monday the U.S. is "looking to" add as many as 75 million barrels of oil to the Strategic Petroleum Reserve. Trump spoke after an historic day in the oil CL.1, +103.61% markets, in which the May WTI crude contract closed at -$37.63 a barrel, a one-day drop of 306%. Trump said he was considering the move "based on the record low price of oil," and that the action would "top it out." Speaking at a White House press briefing, Trump said, "we'd get it for the right price."
Based on a vague memory from years ago - so I could be totally wrong here - you're assuming knowledge he doesn't have.
Correct me if I'm wrong, but: The people doing the trading are middlemen, and have no capacity period. They expected to be able to sell it all off to the energy companies, even at a loss, so they normally don't accept any physical product. But the energy companies ran out of capacity - something the middlemen (traders) don't have direct knowledge of - so got caught unexpected with contracts they can't sell, and now have to accept the physical product.
