Why Obama’s war on oil speculators is economic poppycock (onions or corn?)

Economist Dr. Mark Perry has a series of posts at his blog Carpe Diem which makes the case that “speculators” play and key and positive role in commodities markets.

One of the more intriguing posts deals with onions and oil.  Oh, and corn.   Perry quotes a 2008 Fortune magazine article:

"Before the government starts scrutinizing the role that speculators may have played in driving up fuel and food prices, investigators may want to take a look at price swings in a commodity not in today’s news: onions.

The bulbous root is the only commodity for which futures trading is banned. Back in 1958, onion growers convinced themselves that futures traders were responsible for falling onion prices, so they lobbied an up-and-coming Michigan Congressman named Gerald Ford to push through a law banning all futures trading in onions. The law still stands.

And yet even with no traders to blame, the volatility in onion prices makes the swings in oil and corn look tame, reinforcing academics’ belief that futures trading diminishes extreme price swings."

The proof is in the charts.  The first chart compares the volatility in the onion market, in which futures trading was banned, with that of the oil market.

Compare the mean and standard deviation differences in the two markets.  Remember blue – no futures trading.  Red – futures trading.

So, you say, comparing onions and oil is like, well, comparing onions and oil!   OK, how about onions an corn.  Again the same difference applies.  No futures trading for onions but there is with corn.

Result?  The same:

corn

The point, of course, is those futures contracts help moderate a market.  Or as Perry says:

The fact that the volatility of onion prices is so much greater than the volatility of corn prices lends further statistical support to the notion that markets with futures trading like corn have lower price volatility than markets without futures contracts like onions.

Bingo.  So, the President’s war on “oil speculators” is an obvious distraction.  But here’s the other side of that – if successful, you may end up seeing oil act like onions.  Is that something most of us would prefer?  Given these facts, it seems the height of folly to attempt to regulate or ban futures trading in oil, doesn’t it?

A few more charts to finish the point.  First, futures trading in natural gas:

natgas

If oil speculation (or, as implied, greed) is the cause of rising oil prices, why aren’t natural gas prices rising as well in futures trades (not as “greedy”)? 

In fact, it is because of “speculators” that we’ve seen the price of natural gas go down.  So futures markets do what?  They react to market signals on supply and demand.  What this tells us is we most likely have an over abundance of natural gas.

So what does the market do? It adjusts the price to the reality of the supply v demand – in this case, the price goes down.  And it also does things like this:

rigs

When natural gas price were up and oil prices down, more drilling rigs were allocated by those markets to natural gas.  As oil prices have risen dramatically recently, while natural gas prices have fallen, there’s been just as dramatic a shift in the allocation of drilling rigs from natural gas to oil.

The success in the natural gas sector has driven supply up while demand has yet to increase proportionately.  Meanwhile, we’d had an abundant supply of oil, which has now become very tight (geopolitics, folks – governments at work and war) driving up the price of crude.  The market is reacting.

And as it reacts, guess what?

Crude futures are down as they obviously see future supply growing as the market adjusts and reacts.  All driven by “speculators” who are, right now, in the middle of moderating the market.

So, as President Obama continues with his “blame the speculators” nonsense, you have a choice. 

Onions or corn?

Markets or bureaucrats?
