NEW YORK (Reuters) - Oil prices rose nearly 4% on Wednesday after President Donald Trump falsely claimed victory in a tight U.S. election with millions of votes still to be counted and after data showed a large decline in U.S. crude inventories. A victory by Trump is viewed as bullish for oil because of sanctions on Iran and his support for Saudi-led oil production cuts to support prices. A contested result and prolonged uncertainty is seen as the most bearish outcome for oil and markets in general, while a win for Joe Biden would be seen as bearish to neutral because of his support for green policies and softer stance on Iran. West Texas Intermediate CLc1 ended the session up $1.49, or 4%, at $39.15 a barrel, while Brent crude LCOc1 settled up $1.52, or 3.8%, at $41.23 a barrel. Both benchmarks extended gains to session highs after data showed U.S. crude inventories fell 8 million barrels last week as Hurricane Zeta forced production declines in the Gulf of Mexico during the period. [EIA/S] U.S. weekly crude oil exports fell by 1.2 million barrels per day (bpd) to about 2.3 million bpd last week, the biggest drop since January, and production dropped 600,000 bpd to 10.5 million bpd. Trump falsely claimed to have won after his Democratic challenger Biden said he was confident of winning a contest that will not be resolved until a handful of states finish vote counts in the next hours or days. “Perhaps the biggest conclusion to be drawn at this stage is that there is only a small likelihood that existing oil & gas tax incentives will be removed in the U.S. – even if Biden emerges as the winner – given the narrow margin of victory and a probable Republic majority in the U.S. Senate,” said Artem Abramov, head of shale Research at Rystad Energy. Wall Street surged and U.S. dollar gained against a basket of currencies, as the too-close-to-call presidential election left traders betting on a divided Senate that would keep stimulus flowing but hold tax rises and regulation in check.

The Organization of the Petroleum Exporting Countries (OPEC)and allies led by Russia, a grouping known as OPEC+, earlier agreed to ease cuts by 2 million barrels per day from the current 7.7 million bpd from January.

Italy, Norway and Hungary have tightened coronavirus curbs, following Britain, France and other countries. Britain recorded 492 new COVID-19 deaths on Wednesday, the biggest toll since May 13 and up from 397 on Tuesday, government data showed.
