LONDON, April 23 (Reuters) - Oil rose towards $50 a barrel on Thursday as a rally in European equities markets encouraged investors to focus on the prospects for a rebound in oil demand once the global recession begins to ease.
Sentiment on the global economy and oil demand has been solidly bearish in recent months and the International Monetary Fund on Wednesday slashed its outlook for this year, forecasting the deepest recession since World War II.
But the second quarter is traditionally the weakest of the year for oil demand and many traders expect a strengthening in supply and demand fundamentals towards the end of the year.
U.S. crude <CLc1> was up 60 cents at $49.45 a barrel by 1040 GMT, after dropping as much as 48 cents in early Asian trade. London Brent crude <LCOc1> rose 30 cents to $50.11.
"We're coming into Q2, gasoline demand is going to increase, refining rates are going to go up and I expect inventories will be tapering off," said Kevin Norrish, oil analyst at Barclays Capital, explaining why some investors predict oil prices will strengthen.
Bolstering sentiment for oil was a rally in European stock markets, which turned positive mid-morning on commodity shares and after results for Credit Suisse <CSGN.VX> and Novartis <NOVN.VX> pleased investors. [

FUNDAMENTALS
Stock markets tend to lead sentiment in commodities markets as investors monitor them as a distillation of views on the prospects for the economy.
But oil fundamentals, at least in the short and medium term, remained bearish.
The IMF forecast on Wednesday that the global economy would shrink by 1.3 percent this year, sharply weaker than the 0.5 fall it predicted in January. [
]Underlining the weak demand, crude stockpiles in the world's top energy consumer jumped to a fresh 19-year high last week, the U.S. Energy Information Administration said, despite a 3 percentage point rise in refinery utilisation rates. [
]The weak economy has slashed demand and pulled oil back from its record high above $147 per barrel hit in July last year, with expectations for growth continuing to be slashed. The Royal Bank of Scotland (RBS) <RBS.L> said on Thursday it cut its oil price forecasts for 2009 and 2010.
RBS now sees Britain's North Sea Brent crude averaging $56.10 per barrel this year, down from a previous forecast of $80 a barrel, but expects prices to recover to $75 in 2010, compared with an earlier forecast of $76.25.
"OPEC's production restraint will create a tighter market, which we believe will progressively lift oil prices this year, although the rate of recovery should be somewhat slower than previously assumed," the bank said.
Brent prices <LCOc1> have averaged $46.87 so far this year.
