Crude oil prices rose on Tuesday as the dollar eased slightly, but concerns about oversupply remained front of mind with OPEC expected to keep its output target unchanged at a policy meeting on Friday. U.S. crude CLc1 was trading up 34 cents at $41.99 a barrel at 0226 ET, but was still down more than 10 percent since the start of November. Internationally traded Brent LCOc1 was also up 34 cents at $44.95 a barrel. A weakening of the dollar – which dipped against a basket of currencies on Tuesday – makes greenback-denominated contracts such as oil futures cheaper for those holding other currencies. “If we saw selling of the dollar and buying of the euro, it could support oil prices and give us a bit of a rally,” said Ric Spooner, chief market analyst at Sydney’s CMC Markets. “It’s really a bit of an ECB wild card at the moment.” The European Central Bank (ECB) is widely expected to cut interest rates on euro deposits and extend its quantitative easing program at a key meeting on Thursday. Still, traders and analysts remained bearish about oil.
