LONDON, May 21 (Reuters) - Oil prices fell towards $70 a barrel on Friday, haunted by concerns that Europe's debt crisis could hurt global economic growth and slow energy demand.
U.S. crude for July delivery <CLc1> was trading 42 cents lower at $70.38 a barrel by 0915 GMT, having fallen to $69.31 earlier. On Thursday, the expired June contract briefly touched a nine month low of $64.24 in the largest intraday price range of around $7 since the end of 2008.
U.S crude has fallen about 20 percent from $87 hit on May 3, battered by loss of confidence in global markets due to the crisis in the euro zone triggered by Greek debt problems.
ICE Brent crude futures <LCOc1> fell 24 cents to $71.60 a barrel.
"The oil market is still in a state of confusion between actual impact on demand from the eurozone crisis and the bearish sentiment across currency and equities market and so on," said Andy Sommer, energy market analyst with EGL in Switzerland.
The ongoing Greek sovereign debt crisis and Germany's unilateral ban on some speculative trades damped the euro to the four year low earlier this week.
On Friday, the euro held broad gains, after investors wary of holding too many short positions following its heavy sell-off scrambled to take off those trades as fears of currency intervention rose. [
]World stocks as measured by the MSCI All-Country index <.MIWD00000PUS> were down slightly, having suffered a near three-percent drop on Thursday, the biggest one-day percentage fall in a year.
The FTSEurofirst 300 <
> index of top European shares also fell. [ ]Germany is set to approve its share of a $1 trillion safety net for troubled euro zone states later today and European finance ministers are meeting to discuss changes to budget rules to prevent another Greek-style debt crisis. [

U.S. crude futures particularly came under further pressure this week due to record high levels of inventories at Cushing, Oklahoma, the delivery hub for the underlying oil for the futures. [
] [ ]On the other hand, EGL's Sommer pointed out some signs of recovery in broader oil demand. Statistics have shown oil demand in the United States and China, the world's top two oil consuming markets, has been relatively strong.
On Wednesday, U.S. government data showed total product demand over the past 4 weeks was 19.21 million bpd, up 4.8 percent from a year ago. [
]China's official data showed country posted record rates both in refinery output and crude imports in April, following seven months of double-digit growth in apparent oil demand. [
