* EIA report likely to confirm large jump in US crude stocks
* OPEC to slash demand forecasts in monthly report due later (Updates with prices)

SINGAPORE, April 15 (Reuters) - Oil fell for a third day to hover above $49 a barrel on Wednesday, hit by a large jump in U.S. crude stocks and weak economic data that dented hopes of demand recovery in the world's top energy user.
The market is waiting to see if the U.S. Energy Information Administration's (EIA) weekly report, due later in the day, confirms the higher-than-expected build in crude inventories from the American Petroleum Institute.
By 0630 GMT, U.S. crude for May delivery <CLc1> was down 6 cents at $49.35 a barrel, after falling to $48.92 earlier, and by nearly 1.3 percent overnight. ICE Brent crude <LCOc1> was down 17 cents at $51.79 a barrel.
Oil prices have been stuck in a $47-$54-range for the past four weeks, having recovered from a low of $32.40 in December. They are still down almost $100 from a record high above $147 last July.
"Crude fell on the back of weaker-than-expected March retail sales, which also dragged on equities, and the main worry is still the large weekly increase in crude inventories," said Peter McGuire, the Managing Director of Commodity Warrants Australia.
Industry group American Petroleum Institute (API) said on Tuesday that U.S. domestic crude stocks had risen by 6.5 million barrels last week, much higher than a 1.9 million-barrel increase forecast in a Reuters poll. [
]The EIA report, due at 1430 GMT, is likely to show that U.S. crude oil supplies rose for the sixth consecutive week, probably to the highest in almost 19 years as imports rebounded, a Reuters poll of analysts showed. [
]Collapsing demand has been the main driver of the builds. In its monthly outlook released on Tuesday, the EIA cut its 2009 world oil demand forecast by 180,000 barrels per day to just over 84 million bpd. [
]This comes after the International Energy Agency (IEA) slashed its world oil demand forecast for 2009 last Friday, sending oil prices down by 4 percent on Monday. [
]Oil and other markets have been lifted by some glimmers of hope that the U.S. economy was turning around. But U.S. stocks slumped overnight as surprisingly bearish retail sales figures dimmed hopes the recession was abating.
The data, which showed that sales at U.S. retailers fell an unexpected 1.1 percent in March after rising for two straight months, sparked selling across the market. [
] [ ]"The market will be watching for the early results of the U.S. reporting season and the impact on equities -- there's a very close correlation between oil and stock markets," said Mark Pervan, a senior commodity strategist with ANZ Bank.
The dollar and yen rallied after the disappointing U.S. retail sales data and investor caution about corporate earnings boosted safe-haven flows into the two currencies. [
]Traders will also be eyeing OPEC's report, in which it is expected to slash oil demand forecasts. A more bearish view on oil demand could bolster support for a further tightening in supplies. Its last report saw demand dropping by 1.01 million bpd in 2009. [
]On the supply front, Saudi Arabia will trim oil supplies to some of its Asian customers in May. [
]Saudi Arabia has been largely responsible for OPEC's high level of compliance -- estimated at around 80 percent -- with agreements to cut output by a total of 4.2 million bpd since September last year.
