NEW YORK, June 22 (Reuters) - World shares climbed on Friday but were on track for their biggest weekly decline in three months due to trade war fears, though oil prices surged after OPEC decided on a modest production increase.
U.S. Treasury yields edged higher, trading in narrow ranges as risk appetite improved a bit but worries over a trade conflict with China kept investors cautious.

The energy sector was the benchmark S&P 500 index's biggest percentage gainer as oil prices rose sharply after OPEC agreed to only a modest increase in output to compensate for losses in production at a time of rising global demand.
U.S. crude rose 4.12 percent to $68.24 per barrel and Brent was last at $74.69, up 2.25 percent on the day.
"The effective increase in output can easily be absorbed by the market," Harry Tchilinguirian, head of oil strategy at French bank BNP Paribas, told the Reuters Global Oil Forum.
However, investor nervousness over a possible full-blown trade war deepened this week over increasingly sharp rhetoric between the United States and China, and growing evidence of the wider economic impact of this conflict.
