* Oil ticks up with eyes on virus, Libya * Dollar index posting strongest gain this month (Updates prices, changes comment, dateline; previous LONDON) NEW YORK, April 22 (Reuters) - Global stocks fell on Thursday weighed by Wall Street after a report that the Biden administration will propose a sharp increase to capital gains tax, while the dollar index gained as the euro and pound gave back some of the month’s gains. Oil prices were little changed as concerns over Libyan output offset worries that rising coronavirus cases in India and Japan would cause energy demand to decline. On Wall Street, indexes turned lower after a Bloomberg report that the Biden administration would propose to lift the capitals gains tax to near 40% for wealthy individuals, nearly double the current rate. “If they’re going to tax people more and their net is going to fall, the value of that instrument is lower. Incentives matter,” said Kim Forrest, chief investment officer at Bokeh Capital Partners in Pittsburgh. “A lot of money that’s in the market at this point is non taxable, and I don’t think people do that calculation. Whenever they see news (like this), they just sell, they want to take the gains this year.” The Dow Jones Industrial Average fell 394.34 points, or 1.16%, to 33,742.97, the S&P 500 lost 44.88 points, or 1.08%, to 4,128.54 and the Nasdaq Composite dropped 153.66 points, or 1.1%, to 13,796.56. MSCI’s gauge of stocks across the globe shed 0.35% and the pan-European STOXX 600 index rose 0.68%. Emerging market stocks rose 0.28%. MSCI’s broadest index of Asia-Pacific shares outside Japan closed 0.28% higher, while Japan’s Topix rose 1.82%. Treasury yields fell alongside stocks on the capital gains tax issue. Benchmark 10-year notes last rose 3/32 in price to yield 1.5539%, from 1.564% late on Wednesday, remaining in a tight range so far this week. Oil prices were in and out of positive territory as traders weighed lower output in Libya with concern over demand from India, the third-largest global consumer. “The market realized that a global comeback in oil demand cannot come without a comeback of the world’s largest economies,” said Bjornar Tonhaugen, head of oil markets at Rystad Energy, noting “India is diving deeper and deeper into a major crisis with infections setting new records every day.” U.S. crude rose 0.02% to $61.36 per barrel and Brent was at $65.30, down 0.03% on the day. In currency markets, the dollar rose as the pound gave back some of its recent sharp gains while the euro was weighed by an ECB statement that was hopeful on the economic recovery but lacking in details about the stimulus removal. U.S. Federal Reserve and Bank of Japan meetings follow next week. The dollar index rose 0.247%, with the euro down 0.22% to $1.2006. The Japanese yen strengthened 0.02% versus the greenback at 108.05 per dollar, while Sterling was last trading at $1.3833, down 0.69% on the day. The Russian ruble rose against the dollar after Moscow signaled an end to military drills near the Ukraine border, easing some of the geopolitical risk premium. The ruble strengthened 1.77% versus the greenback at 75.57 per dollar. Turkish markets suffered under the weight of expectations that U.S. President Joe Biden will formally recognize the massacre of Armenians by the Ottoman Empire during World War One as an act of genocide. The lira lost 1.64% versus the U.S. dollar at 8.31. Spot gold dropped 0.7% to $1,781.86 an ounce. Silver fell 1.83% to $26.09.
