LONDON, Sept 29 (Reuters) - An agreement by OPEC members to curb output boosted oil company shares on Thursday, lifted the currencies of crude-producing countries, and drove yields on low-risk government debt higher.
Global stocks were pulled higher by the oil company rally.
Oil prices, however, edged off their highs as some investors took profits on Wednesday's more than 5 percent surge, which was prompted by OPEC's first deal to limit output since 2008. Scepticism over how it would be implemented also crept in.
But the surprise agreement boosted investors' appetite for riskier assets and saw the safe-haven yen fall 1 percent against the dollar at one point.
"Everything you're seeing today is a response to the move in crude and the possible coordination necessary for OPEC to do what it has announced. Even though I think the agreement is probably a bit flimsy, the amount of coordination is part of the reason for the rally in risk," said BMO Capital Markets currency strategist Stephen Gallo.

An inflationary rise in oil prices would rattle investors already nervous that an era of central bank stimulus may be coming to an end.
However, given doubts about the deal, BNP Paribas (PA:BNPP) European rates strategist Patrick Jacques said the upward pressure on bond yields would prove temporary.
"Even if there's a 5 percent rise in oil prices, this will not trigger a strong rebound in inflation and at these levels, oil output is still higher than demand so we're unlikely to see a massive rally in oil," he said.
