Haven’t they ever heard of "supply and demand"?

United Airlines has joined the chorus of organizations blaming speculators for the dramatic rise in fuel prices.

Yes, prices are higher. Yes, there are more speculators. That doesn’t make a cause-and-effect. Perhaps there are more speculators because prices are rising — not vice-versa. That’s not the politically correct viewpoint, because it’s attractive to find a scapegoat.

And thus, we have an “open letter” to all airline customers, sent to me last week by United Airlines. It is also signed by AirTran Airways, Alaska Airlines, American Airlines, Continental Airlines, Delta Air Lines, Hawaiian Airlines, JetBlue Airways, Midwest Airlines, Northwest Airlines, Southwest Airlines and US Airways.

An Open letter to All Airline Customers:

Our country is facing a possible sharp economic downturn because of skyrocketing oil and fuel prices, but by pulling together, we can all do something to help now.

For airlines, ultra-expensive fuel means thousands of lost jobs and severe reductions in air service to both large and small communities. To the broader economy, oil prices mean slower activity and widespread economic pain. This pain can be alleviated, and that is why we are taking the extraordinary step of writing this joint letter to our customers. Since high oil prices are partly a response to normal market forces, the nation needs to focus on increased energy supplies and conservation. However, there is another side to this story because normal market forces are being dangerously amplified by poorly regulated market speculation.

Twenty years ago, 21 percent of oil contracts were purchased by speculators who trade oil on paper with no intention of ever taking delivery. Today, oil speculators purchase 66 percent of all oil futures contracts, and that reflects just the transactions that are known. Speculators buy up large amounts of oil and then sell it to each other again and again. A barrel of oil may trade 20-plus times before it is delivered and used; the price goes up with each trade and consumers pick up the final tab. Some market experts estimate that current prices reflect as much as $30 to $60 per barrel in unnecessary speculative costs.

Over seventy years ago, Congress established regulations to control excessive, largely unchecked market speculation and manipulation. However, over the past two decades, these regulatory limits have been weakened or removed. We believe that restoring and enforcing these limits, along with several other modest measures, will provide more disclosure, transparency and sound market oversight. Together, these reforms will help cool the over-heated oil market and permit the economy to prosper.

The nation needs to pull together to reform the oil markets and solve this growing problem.

I am not convinced that more government regulation is the solution to the rise in oil prices.
