NEW YORK, June 21 (Reuters) - Crude oil prices jumped to a 6-1/2-week high on Monday, after China's move to make its currency more flexible raised expectations of stronger demand from the world's second largest energy consumer.
At 11:56 a.m. EDT (1556 GMT), U.S. crude for July delivery <CLc1> was up $1.37, or 1.78 percent, at $78.55 a barrel, having reached $78.92, the highest since $80.39 was struck on May 6.
August ICE Brent <LCOc1> rose $1.21 to $79.43 a barrel.
China's yuan on Monday posted its biggest daily surge since its July 2005 landmark revaluation, sending a signal ahead of this weekend's G20 summit that Beijing is keeping its word and allowing greater currency flexibility. [
]The yuan closed at 6.7976 versus the dollar, up 0.42 percent from Friday's close of 6.8262. The 6.7958 intraday peak was an all-time high since the revaluation. [
]Analysts said a stronger yuan against the U.S. dollar might make Chinese imports of dollar-denominated oil less expensive, boosting demand consumption. [
]"The policy shift in China to allow the yuan to strengthen ought to stimulate domestic oil demand. That's the underlying reason for the marker going higher," said Christopher Bellew, London-based oil broker at Bache Commodities.
But the longer-term impact on oil and other commodity prices may be small, according to some analysts, since China will not let the yuan rise sufficiently high to make much difference to its companies' spending power on commodity imports [

Copper and metals such as platinum and palladium were also up strongly on Monday in response to the news about the yuan, since China is a large importer of these commodities.
Reuters' analysis of official Chinese figures on Monday showed China's oil demand fell in May from April, though it remained up 9.4 per cent from year ago. [
].U.S. crude prices have recovered about 21 percent from the May 20 $64.24 intraday low, but remain more than $8 below the 2010 peak of $87.15 struck on May 3.
The technical picture took on a renewed bullish cast, as NYMEX crude stretched its gain after opening above the 50-day moving average to quickly find resistance at the 100-day moving average.
"We have broken above the range around $75 and we would expect prices to now rise above $80," said Amrita Sen, analyst at Barclays Capital in London.
European and U.S. stock markets <

Markets await confirmation that low interest rates and other economic stimulus measures will remain in place.
In the background, but supportive to crude prices, is the dispute over Iran's nuclear program. Iran has barred two U.N. nuclear inspectors, adding to tension after Tehran was recently hit by new sanctions over its nuclear program. [
]Russia cut gas supplies to Belarus by 15 percent on Monday, pressing its neighbor to pay a $192 million debt and raising fears of disruptions in deliveries to Europe. [
