Oil prices have been rising in recent weeks. At the beginning of October 2010, the spot price of Brent Crude was $80 per barrel. By December it has passed $90 per barrel. There is some way to go before it gets to the levels of mid-2008, when it peaked at over $140 per barrel (only then to fall rapidly as the world slid into recession, bottoming out at around $34 per barrel at the end of 2008).

Higher oil prices are a worry for governments around the world as they threaten higher inflation and put recovery from recession in jeopardy. You will probably have noticed the higher petrol prices at the pumps. If you spend more on petrol, you will have less to spend on other things.

So why have oil prices risen and are they likely to continue rising? The following articles examine the causes of the recent surge and look ahead to the likely response from OPEC and the path of oil prices next year.

The pound has been rising against the US dollar recently. And as the dollar has fallen, so the prices of various commodities, such as gold and silver, have been rising. So what are the reasons for these currency and commodity price movements? The simple answer is that they merely reflect changes in demand and supply. But why have demand and supply been changing? Are there changes in the underlying economic fundamentals, or do they largely reflect speculation in times of uncertainty and resulting market overcorrection? The following articles address these questions.

With oil prices over $100 a barrel and petrol prices over £1 per litre, it is difficult to imagine a county where the entire tank of a 4×4 can be filled for 42p, but Venezuela is just such a country. Not surprisingly, Venezuelans are resisting any attempt to change the level of subsidy that creates this situation.
