European stock index futures fell on Monday, following a slump in Asian shares, and the euro slid amid scepticism that Europe's latest efforts to contain its sovereign debt crisis can prevent it from wreaking more damage on the world economy.
A broad commodities rout continued, with precious metals, industrial metals and oil all in headlong retreat as investors rushed to take riskier bets off the table and preserve their capital.
Gold fell nearly 5 percent, extending losses after sliding a record $100 an ounce on Friday as safe haven seekers abandoned the precious metal in favour of the dollar and U.S. Treasuries, while silver tumbled 15 percent.

"We believe this type of plan would be seen as a credible solution to the crisis," said Warren Hogan, chief economist at ANZ Bank in Sydney.
"However, this plan is still only in the 'rumour' stage, and it may face some tough hurdles in order to be passed by all EU authorities, indeed headlines are already suggesting some German dissent."
Euro STOXX 50 index futures futures fell 1.1 percent. Futures for Germany's DAX and France's CAC-40 also fell more than 1 percent, while spreadbetters called London's FTSE 100 to open lower.
S&P futures fell nearly 1 percent, pointing to further losses for Wall Street as well later in the day.

After a weekend of being told by the United States, China and other countries that they must get more aggressive in their crisis response, European officials focused on ways to beef up their existing 440 billion euro ($595 billion) rescue fund.

Global equity markets have been tumbling since late July, hammered by twin fears of renewed recession in the United States and worries that Europe's intractable debt woes could trigger another full-blown banking crisis.
MSCI's Asia ex-Japan index has lost almost 30 percent since its April high for the year, while the All-Country World index is 23.3 percent below its May peak.
Emerging Asian markets that were outperformers earlier this year have been hit hard as fund managers sell profitable assets to fund losses elsewhere or pile into the safety of cash. Thai stocks fell nearly 8 percent on Monday, and Philippine shares 4.2 percent.
The euro, which was threatening the $1.50 level in May, has also been under heavy pressure in recent weeks amid growing expectations among policymakers, investors and market economists that Greece may have to default on its debts.
"The lurch lower in risk appetite can only reflect a growing fear that policymakers will be incapable of acting in time or with sufficient potency to turn things around," said Herve Goulletquer, analyst at Credit Agricole.
"Given so much hinges on restoring confidence, not just of financial markets but of all economic agents, this trauma and the associated grim headlines risk tipping the global economy over the edge."

Commodities continued their slide, after being sold off across the board last week in a broad pullback from riskier assets and as the rising dollar increased the cost of dollar-denominated assets for holders of other currencies.
Oil extended losses, after falling to six-week lows on Friday as fears of renewed recession in the developed world raised worries of weaker demand.
U.S. crude fell 2.2 percent to 78.05 barrel and Brent crude lost 1.6 percent to $102.30.
Fears of flagging demand hammered industrial metals last week, when copper suffered its sharpest weekly decline in nearly three years.
