The price of oil has reached a new high for 2009, continuing its recent rise on the back of the weak US dollar and strong US company results.

由于美元的弱势和美国公司的强势共同作用，石油价格一路攀升并达到2009年新高。

US crude settled up $1.08 at $79.61 in New York trading. Meanwhile London Brent crude rose 78 cents to at $77.77

Oil prices surged（汹涌，澎湃） last week, as encouraging US bank results fuelled optimism for the global economy.

Analysts¹ said the short-term direction of oil would depend on the dollar and the next round of corporate² results.

And there was much caution that the price rises seen in recent days could easily be reversed.

"The spectacular gains were overwhelmingly driven by financials and market optimism rather than fundamentals," said JBC Energy in Vienna, adding there was "no reason" why prices should not return to between $65 and $75 where they had been for several weeks.

They believe the price of oil is more likely to drop back rather than move higher once fundamental factors re-establish themselves as the main driver of the oil price.

These factors include spare capacity, low profit margins³ for refiners（提炼器）, a "massive stock surplus" of products such as diesel⁴（柴油机，内燃机） and heating oil, and lacklustre demand among industrialised nations, JBC argued.

The dollar lost more ground against the euro in early trading, falling to $1.4940, just short of a 14-month low of $1.4967 seen last week.
