LONDON, Sept 5 (Reuters) - World stocks extended losses to fresh two-year lows while save-haven government bonds rallied on Friday after a surprisingly weak U.S. jobs report deepened worries about the health of the global economy.
The U.S. unemployment rate shot up to 6.1 percent in August, its highest in more than 4-1/2 years, while the economy lost a higher-than-expected 84,000 jobs last month.
Interest rate futures moved to show a small chance the Federal Reserve might cut rates later this year. U.S. stock futures remained in the red <SPc1>, indicating a weaker opening on Wall Street, which posted its steepest decline in more than two months on Thursday.
"This is more convincing evidence that the economy is still in trouble and investors are seeking safer places to park their money," said Gary Thayer, senior economist at Wachovia Securities in St Louis.
"We're also seeing weakness around the globe so there's less reason for the Fed to focus on inflation and more reason to focus on getting the economy back on its feet."
The FTSEurofirst 300 index <
> fell 1.8 percent, following even steeper moves in Asian stocks.The MSCI main world equity index <.MIWD00000PUS> dropped 1.0 percent, having hit its lowest since July 2006. The index has suffered six sessions of consecutive losses and already lost 5.6 percent since the start of the month.
Bank stocks took a hit after the European Central Bank tightened rules on the assets banks can submit as collateral in central bank lending operations, following concern that its rules have been open to misuse.
The ECB is set to increase the safety margin it takes in valuing assets, known as the haircut, to 12 percent across the board for all asset-backed securities (ABS) which banks deposit with the ECB to receive short-term funding and access payment systems.
Analysts say the changes would make it less attractive for banks to use ABS as collateral and would push up the overall cost of borrowing funds from the central bank.
WAVE OF RISK AVERSION
European currencies extended their recent decline on concerns that economies outside the United States are also deteriorating, especially in Europe -- which is facing recession.
Deepening such concerns, German industrial output fell by a bigger-than-expected 1.8 percent in July, dipping for the fourth time in five months.
"There is no prospect of an early end to the current downwards trend," Commerzbank noted on the German economy. "Both the much gloomier business sentiment and the very weak trend in order intake lead us to expect production will continue to fall, reflecting weak demand from abroad -- especially from other euro area countries -- and the end of the domestic investment boom."
The euro <EUR=> had fallen to a 11-month low below $1.42 while sterling hit a 12-year low on a trade-weighted basis <=GBP>.
The low-yielding yen surged to a 13-month high around 150.60 per euro <EURJPY=R> while it hit two-year lows against the Australian and New Zealand dollars.
The dollar <.DXY> fell 0.5 percent against a basket of major currencies. Still, the index is up nearly 9 percent in the third quarter, on track for a biggest quarterly gain since the fourth quarter of 1992.
Emerging sovereign spreads <11EMJ> widened 11 basis points to trade 332 basis points above U.S. Treasuries. Emerging stocks <.MSCIEF> lost 2.4 percent to fresh 17-month lows.
The September Bund future <FGBLU8> rose 73 ticks, benefiting from flows into safe-haven government bonds.
Concerns that the slowing economy would hit energy demand weighed on U.S. light crude <CLc1>, which fell 0.4 percent to $107.37 a barrel. Gold <XAU=> rose to $808.90.
