European and US markets were expected to build on the Asia stocks rally, with London bookies calling for German shares to open 2% higher and early futures trading pointing to Wall Street gaining 1.4% to hit a new 18-month high.
Financial bookmakers in London expected Britain's FTSE to open 1.27% higher, Germany's DAX to start up nearly 2% and France's CAC-40 to begin about 1.7% higher.
Former Iraqi president Saddam's capture by US troops late on Saturday saw crude prices fall more than a dollar as it raised the prospect of fewer sabotage attacks on Iraq's oil industry and a boost to world supplies.
Gold prices tumbled as the dollar rose, while Japanese stocks jumped more than 2%, boosted by exporters such as Toyota Motor Co.
Analysts said hopes for a shorter US occupation in Iraq would be a plus for the US economy and a psychological boost for the beleaguered dollar, but the impact was likely to be short-term, given the rising US current account and budget deficits.
"At least for now, we should see a swifter-than-expected end to the US occupation in Iraq and that's welcome," said Kazunori Jinnai, general manager at Daiwa Securities SMBC.
"There will be some early applause from Wall Street, but it will be subdued because there is a long road ahead"

Ten-year US Treasuries fell more than a half point to 99-17/32, pushing their yield to 4.31% from 4.24% in late US trade on Friday.
Japanese government bonds (JGBs) fell as stocks jumped, but declines were seen as limited as many traders remained sceptical over whether violence in Iraq would cease.
"Stocks went up and bonds fell as the initial reaction but I don't think this will continue," said Hiroyoshi Sandaya, an analyst at Goldman Sachs. "This effect may last only for today."
The yield on Japan's benchmark 256th 10-year cash bond was up six basis points at 1.355%.
US indexes up
Major US stock indexes have risen sharply since the start of US military operations in Iraq in March, propelled by signs of a reviving economy and higher corporate profits.
A rally on Wall Street on Monday could carry the blue-chip Dow Jones industrials to fresh 2003 highs above the key 10,000 mark, which it closed above on Thursday for the first time in nearly 19 months.

Japan's Fujitsu and Toyota each climbed more than 2%, while in Hong Kong, oil firms PetroChina and CNOOC each fell about 2%.
South Korea's Hyundai Engineering and Construction Co shot up by a daily limit of 15%, on hopes that $1.1 billion owed by Iraq could be forthcoming.

The market will also look at the US consumer price index on Tuesday, a key gauge of inflation.
US oil dropped to $32.02 a barrel, while gold was quoted
