NEW YORK (Reuters) - Equities in key world markets edged higher on Thursday, led by gains on Wall Street after an upward revision to U.S. economic growth data, while U.S. crude rose to trade above $50 per barrel for the first time in three weeks.
The euro slipped after data showed easing inflation in Spain and Germany, paring back bets on tighter policy from the European Central Bank.
Oil prices rose after Kuwait gave its backing for an extension of OPEC production cuts in an attempt to reduce global oversupply.
"There is a significant chance that a short-to-medium-term bottom has been found," said Tamas Varga, analyst at London brokerage PVM Oil Associates.
U.S. crude last rose 1.7 percent to $50.33 a barrel and Brent traded at $52.94, up 1.0 percent on the day.

Banks and energy led U.S. stocks higher as oil prices rose and gross domestic product annualised growth was revised up to a 2.1 percent rate from 1.9 percent. Growth in consumer spending, which accounts for more than two-thirds of U.S. economic activity, was also revised up.
Much of the move in U.S. stocks, which drove them to record highs earlier this month, is predicated on U.S. President Donald Trump's commitment to return to 4-percent economic growth.
Failure last week to pass a major campaign promise to revamp U.S. healthcare called into question Trump's ability to deliver tax reform even though his party controls the two chambers of Congress. But economic fundamentals give investors some confidence.

GREENBACK GAINS FURTHER
The dollar index ticked up 0.40 percent with the euro down 0.70 percent to $1.0691, weakened by the inflation data.
The soft inflation numbers followed a Reuters report on Wednesday citing sources close to the ECB who said officials there were unhappy with a shift in market expectations toward tighter monetary policy and higher euro zone interest rates.
"That sort of off-the-record briefing that came through (Wednesday) and German inflation this morning do seem to have pulled the rug from under the euro," said Nick Parsons, a strategist with National Australia Bank in London.
Sterling bounced from a one-week low of $1.2375 hit Wednesday , and was last trading at $1.2478, up 0.37 percent on the day.
