If you really want to know, then the answers are a bit complex but I will try to break it down for you.
How to explain the oil price? Why is it so high? Are we running out? Are supplies disrupted, or is the high price a reflection of oil company greed or OPEC greed. Are Chavez and the Saudis conspiring against us?
The dollar is weak because of large trade and budget deficits, the closing of which is beyond American political will. As abuse wears out the US dollar’s reserve currency role, sellers demand more dollars as a hedge against its declining exchange value and ultimate loss of reserve currency status.
In an effort to forestall a serious recession and further crises in derivative instruments, the Federal Reserve is pouring out liquidity that is financing speculation in oil futures contracts. Hedge funds and investment banks are restoring their impaired capital structures with profits made by speculating in highly leveraged oil future contracts, just as real estate speculators flipping contracts pushed up home prices. The oil futures bubble, too, will pop, hopefully before new derivatives are created on the basis of high oil prices.
There are other factors affecting the price of oil. The prospect of an Israeli/US attack on Iran has increased current demand in order to build stocks against disruption. No one knows the consequence of such an ill-conceived act of aggression, and the uncertainty pushes up the price of oil as the entire Middle East could be engulfed in conflagration. However, storage facilities are limited, and the impact on price of larger inventories has a limit.
Perhaps more difficult to understand than the high price of oil are the low US long-term interest rates. US interest rates are actually below the rate of inflation, to say nothing of the imperiled exchange value of the dollar. Economists who assume rational participants in rational markets cannot explain why lenders would indefinitely accept interest rates below the rate of inflation.
Of course, Americans don’t get real inflation numbers from their government and have not since the Consumer Price Index was rigged during the Clinton administration to hold down Social Security payments by denying retirees their full cost of living adjustments. According to statistician John Williams, using the pre-Clinton era measure of the CPI produces a current CPI of about 7.5%.
By pumping out money in an effort to forestall recession and paper over balance sheet problems, the Federal Reserve is driving up commodity and food prices in general. Yet American real incomes are not growing. Even without jobs offshoring, US economic policy has put the bulk of the population on a path to lower living standards.
The crisis that looms for the US is the loss of world currency role. Once the dollar loses that role, the US government will not be able to finance its operations by borrowing abroad, and foreigners will cease to finance the massive US trade deficit. This crisis will eliminate the US as a world power.
And that is the name of that tune!
