Oil prices, stocks up on surprise OPEC deal; gains seen fizzling

Oil prices extended gains after rising nearly 6% on Wednesday after OPEC struck a deal to limit crude output

Oil prices extended gains in Asia on Thursday, boosting stock markets, after OPEC members agreed to curb output in a surprise deal, though investors were wary of chasing markets higher as the US presidential election nears.

MSCI's broadest index of Asia-Pacific shares outside Japan was up 0.8 per cent by mid-morning, thanks to a bounce in energy shares, but other markets such as Hong Kong were starting to cede some of their initial gains.

"Despite the favourable oil deal, foreign institutional investors are sticking to their favourite counters before the US elections results as there is simply too much market uncertainty," said Andrew Sullivan, managing director, sales trading at Haitong International Securities Group in Hong Kong.

Japan's Nikkei climbed 1.4 per cent, after losing 1.3 per cent the previous day.

Oil prices extended gains after rising nearly six per cent on Wednesday after OPEC struck a deal to limit crude output.

It was OPEC's first agreement to cut production since 2008, though details on specific country quotes won't be decided until the next formal OPEC meeting in November.

While markets were broadly optimistic about the deal, some analysts pointed out that a further rise in crude prices may be difficult as US shale producers who have been cutting production in recent months may start increasing output.

Brent crude was up 0.02 per cent at $48.70 a barrel, adding to overnight gains of 5.9 per cent. US crude added 0.3 per cent to $47.17 a barrel after rising 5.3 per cent on Wednesday, when it hit its highest since September 9.

"With profits being squeezed the battle for market share can't go on and this deal ushers in a new period of cooperation between OPEC nations and specifically between Saudi Arabia and Iran," wrote Kathy Lien, managing director of FX strategy for BK Asset Management.

"While we wouldn't be surprised by some back-pedalling between now and November, this is a historic moment and one that should have a lasting impact on the Canadian dollar," added Lien.

Commodity currencies such as the Australian and Canadian dollars firmed on the OPEC news.

The Canadian dollar traded at C$1.3064 to the dollar after gaining nearly one per cent overnight. The loonie had seen a six-month low of C$1.3281 early on Tuesday.

The Australian dollar hit a three-week high of $0.7699, while the Norwegian crown touched a five-month high against the dollar.

The euro inched up 0.1 per cent to $1.12260, while the dollar climbed 0.7 per cent to 101.35 against the safe-haven yen as broader risk sentiment improved.
