WTI-WTF? Part II (of How Many???)

Just another day at the Globex, folks. May WTI up a mere $49.88 on its last trading day at the time I write this paragraph, a while before the close. (Sorry, can’t calculate a percentage change . . . because the base number is negative!) That’s just sick. But at least it’s positive! ($12.25. No, $9.96. No . . .) (This reminds me of a story from Black Monday. My firm did a little index arb. We called the floor to get a price quote on the 19th. Our floor guy said “On this part of the pit it’s X. Over there it’s X+50. Over there it’s X-20. I have no fucking idea what the fucking price is.”)

But June has been crushed–down $7.35 (about 35 percent). Now the May-June spread is a mere $.83 contango. That makes as little sense as yesterday’s settling galactic contango (galactango!) of $57.06. (Note that June-July is trading at at $7.71 and July-August at $2.65.

I’m guessing that dynamic circuit breakers are impeding price movements, meaning that the prices we see are not necessarily market clearing prices at that instant.

A few follow-ons to yesterday’s post.

First, the modeling of the dynamics of a contract as it approaches expiration when the delivery supply/demand curve is inelastic, and some traders might have positions large enough to exploit those conditions to exercise market power, is extremely complicated. The only examples I am aware of are Cooper and Donaldson in the JFQA almost 30 years ago, and my paper in the Journal of Alternative Investments almost a decade ago.

Futures markets are (shockingly!) forward looking. Expectations and beliefs matter. There are coordination problems. If I believe everyone else on my side of the market is going to liquidate prior to expiration, I realize that the party on the other side of the contract will have no market power at expiration. So I should defer liquidating–which if everyone reasons the same way could lead to everyone getting caught in a long or sort manipulation at expiration. Or, if I believe everyone is going to stick it out to the end, I should get out earlier (which if everybody else does the same results in a stampede for the exits.)

In these situations, anything can happen, and the process of coordinating expectations and actions is likely to be chaotic. Cooper-Donaldson and Pirrong lay out some plausible stories (based on particular specifications of beliefs and the trading mechanism), but they are not the only stories. They mainly serve to highlight how game theoretic considerations can lead to very complex outcomes in situations with market power and inelasticity.

One thing that is sure is that these game theoretic considerations don’t matter much if the elasticities of delivery supply and demand are large. Then no individual can distort prices very much by delivering too much or taking delivery of too much. Then the coordination and expectations problems aren’t so relevant. However, when delivery supply or demand curves are very steep–as is the case in Cushing now due to the storage constraint–they become extremely relevant.

Perhaps one analogy is getting out of a theater. When there are many exits, there won’t be queues to get out and little chance of tragedy even if someone yells “fire.” If there is only one exit, however, hurried attempts of everyone to leave at once can lead to catastrophe. Moreover, perverse crowd dynamics occur in such situations. That’s where we were yesterday.

About 90 percent of open interest liquidated yesterday. That is why today is returning to some semblance of normality–the exit isn’t so crowded (because so many got trampled yesterday). But that begs the question of why the panicked rush yesterday? That’s where the game theoretic “anything could happen” answer is about the best we can do.

About that storage constraint. My post yesterday focused on someone with a large short futures position raising the specter of excessive deliveries by not liquidating that position, thereby triggering a cascade of descending offers until the short graciously accepted at a highly profitable price.

But there is another market power play possible here. A firm controlling storage could crash prices (and spreads) by withholding that capacity from the market. The most recent data from the EIA indicates about 55 mm bbl of oil storage at Cushing. That’s about 80 percent of nameplate capacity (also per EIA.). Due to operational constraints (e.g., need working space to move barrels in and out; can’t mix different grades in the same tank) that’s probably effectively full. Therefore, someone with ownership of a modest amount of space could withhold it drive up the spread. If that party had on a bull spread position . . .

Third, we are into Round Up the Usual Suspects mode:

And first in line is the US Oil ETF. There has been a lot of idiotic commentary about this. They were forced to take delivery! (Er, delivery notices aren’t possible before trading ends.) They were forced to dump huge numbers of contracts yesterday! (Er, they publish a regular roll schedule, and were out of the May a week before yesterday’s holocaust. They also report positions daily, and as of yesterday were 100 pct in the June.)

Not to say that USO can be implicated in hinky things going on in the June right now, but as for May–that dog don’t hunt.

Fourth–WTF, June WTI? Well, my best explanation is that the carnage in the May served to concentrate minds regarding June. No doubt risk managers, or risk systems, forced some longs out as the measured and perceived risk for June shot up yesterday. Others just decided that discretion was the better part of valor. The extremely unsettled positions no doubt impaired liquidity (i.e., just as some wanted to get out, others were constrained by risk limits formal or informal from getting in), leading to big price movements in response to these flows. If that’s a correct diagnosis, we should see something of a bounceback, but perhaps not too much given the perception (and reality) of an extremely asymmetric risk profile, with going into expiry short being a lot more dangerous than going into it long. (This is why expectations about future conditions at delivery can impact prices well before delivery.)

Fifth, on a personal note, in an illustration of the adage that the apple doesn’t fall far from the tree (and also of Merton’s Law of Multiples) my elder daughter Renee completely independently of me used “WTI WTF” in her daily market commentary yesterday. I’m so proud! She also raised the possibility of negative prices some time ago. Good call!

And I finish this just in time to bring you the final results. CLK goes off the board settling at $10.01, up a mere $47.64. CLM settles at $11.57, down -$8.86. The closing KM20 spread, $1.56.

Someday we’ll look back on this and . . . . Well, we’ll look back on it, anyways.
