•Global crude futures strengthened Tuesday as market participants looked ahead with some uncertainty at the prospect of US stock data and an OPEC meeting in Vienna on successive days later this week. At 1140 GMT, the April ICE Brent contract changed hands at $61.45/barrel up 71 cents.

•"There are jitters ahead of the OPEC," said a broker. "People are looking for any bullish noises ahead of the meeting and trying to anticipate that. There is some nervous sentiment in the market, with potentially bullish news about US stock data on Wednesday." This reverses four days of consecutive losses for crude futures on the back of weaker product prices.

•Earlier comments by OPEC appear not to have allayed this uncertainty in the market. UAE oil minister and current OPEC president Mohamed bin Dhaen al-Hamli said Tuesday he believed the forthcoming OPEC meeting in Vienna on March 15 would be an "ordinary" one, suggesting there would be no change in OPEC's production. Market sources said seasonality and the changing demand for different products was also playing a role.
