The reason for high oil prices - speculation? One should ask where do these speculators get the money from - there's supposed to be a 'credit-crunch' on with asset-price deflation across the board and tighter lending from banks generally.
You're missing the 'real' reason I feel. It's not speculation per se as the root cause, it's inflation of the supply of money - basically printing money.
As JJBoxster has said housing in the US and UK is a bust for investors. Their multi-trillion losses in worthless mortgage-backed securities have been dumped with taxpayers via the central banks of the US and UK as collateral in return for US Treasuries and UK Gilts - i.e. brand new hard cash!
This as JJBoxster has also said is not going into the busted mortgage market, i.e. lowering of mortgage interest rates, it's going into loans to investors(often part of the bank doing the loaning) to invest in commodity investment vehicles, oil, cereals, metals, but not gold whose price is politically managed, kept down.
Don't believe this Credit Crunch nonsense. Yes there's the mother of all credit retractions for Joe Public, i.e. motgages are as scarce as hens teeth, but in overall terms what is truly happening is a splurge in money supply growth to ensure the major banks do not go bust. The US and UK M3 money supply is growing currently at an unprecedented 20% p..a. That's hyperinflationary. Monetary inflation always leads eventually, 6-12 month typical lag, to price inflation. The US and UK embarked on serious money printing for the failing banks last summer 2007. We are only now beginning to feel the true effects of all these extra dollars and pounds looking for a suitably high investment return. You, Joe Public, unless there's any Rothschilds who regularly read A/Car forums, are being screwed twice over. The value of any savings you have in pounds are being devalued perceptibly each day by runaway monetary inflation. At 20% money supply growth a pound on deposit start of this year will be worth 80p by the end of the year. Plus the price of necessities, food, fuel, electricity, gas, taxes are rocketing due to this surplus printed money being diverted into these necessities of life, chasing a return for their hedge fund owners.
Having said all that there are subtle but important differences between how the US/UK has managed this housing bust compared to the European Central Bank. Unlike the Fed and the Bank of England, the ECB has resisted slashing the central bank rate. So far the Euro-zone looks better placed to bear the 'crunch' due to a stronger currency, cushioning the rise of oil in dollars and so on. It was remarkable listening to the BBC's Economics editor, Robert Peston, interviewing the ECB President, Claude Trichet, this morning and he, Peston, talking about the goal of 'stable inflation' whilst Trichet was talking about 'stable prices'. Note the difference. In the UK inflation is now 'baked in' as they say, meaning get ready for even more devaluation of your savings and accelerating prices. The ECB still believes in squeezing out inflation altogether through tight monetary policy, even if it means lower or negative growth for many Eurozone countries. In the long run they are right. It was also remarkable the comment of some other BBC economics journo on Radio4 this morning asking the BBC's leading female economics reporter, Stephanie Flanders, if she thought the banks were 'happy', after receiving £50bn of taxpayers money to help pay for their self-incurred losses. Has this country and its people gone collectively mad? 'Happy' banks? They're private businesses, who invariably make monstrous profits, and should be let go bankrupt and shreholders broke when they make bad bets in the casino that is the City of London.
