(Adds drop in cryptocurrencies, updates prices) * Graphic: World FX rates tmsnrt.rs/2RBWI5E By Karen Brettell NEW YORK, Sept 7 (Reuters) - The dollar rose for a second straight day on Tuesday, moving further off a near-one month low hit last week, as rising U.S. Treasury yields prompted investors to cut short dollar positions against the euro before a European Central Bank meeting this week. Cryptocurrencies including Bitcoin also dropped sharply in volatile trading as several trading platforms said they experienced performance issues. On Friday, the greenback tumbled to its lowest levels since early August after a surprisingly soft U.S. payrolls report prompted analysts to raise bets the Federal Reserve will not unwind its stimulus plans in coming months. But the dollar has gained in the past two sessions. The greenback rose 0.31% on Tuesday to 92.48, after touching its lowest since Aug. 4 on Friday. “It does appear that after the sell-off the dollar has maybe established a short-term base at least,” said Shaun Osborne, chief FX strategist at Scotiabank in Toronto. “The Federal Reserve we think is still likely to move towards tapering by the end of this year, the U.S. economy is likely to perform relatively strongly, so our view is minor dollar dips, minor dollar weakness is probably a buying opportunity,” he said. Data on Friday showed speculators" net long bets on the U.S. dollar grew in the latest week, with the value of the net long dollar position at $10.98 billion for the week ended Aug. 31, the largest long position since March 2020. The dollar also benefited from rising U.S. Treasury yields before the U.S. government is due to sell $120 billion in new supply this week, including $58 billion in three-year notes, $38 billion in 10-year notes and $24 billion in 30-year bonds. The yield increase "has helped the dollar index to recoup its post-NFP (non-farm payrolls) losses and then some," Brown Brothers Harriman strategists said in a daily note. U.S. 10-year yields which were around 1.299% before Friday"s data release, stand now at 1.366%. The euro was last at $1.1849, below Friday"s one-month peak of $1.1909. The ECB is seen debating a cut in stimulus at its meeting on Thursday, with analysts expecting purchases under the ECB"s Pandemic Emergency Purchase Programme (PEPP) falling possibly as low as 60 billion euros a month from the current 80 billion. The Australian dollar weakened after the Reserve Bank of Australia stuck with plans to taper its bond buying but said it would extend the timeline as the economy struggles with coronavirus lockdowns. The pound also dropped after the British government set out a plan to raise taxes. Cryptocurrencies plunged sharply on Tuesday with bitcoin dropping as much as 19% and ether falling 23%, before paring losses. Several crypto trading platforms said they experienced performance issues on Tuesday though it was not immediately clear if these were a cause or a result of the volatility. Bitcoin was last down 11% on the day at $46,730 and ether was down 12% at $3,466. ======================================================== Currency bid prices at 11:59AM (1559 GMT) Description RIC Last U.S. Close Pct Change YTD Pct High Bid Low Bid Previous Change Session Dollar index 92.4450 92.1920 +0.29% 2.738% +92.5440 +92.1040 Euro/Dollar $1.1849 $1.1872 -0.19% -3.02% +$1.1886 +$1.1838 Dollar/Yen 110.1650 109.8450 +0.31% +6.68% +110.2500 +109.6900 Euro/Yen 130.54 130.35 +0.15% +2.85% +130.6000 +130.3000 Dollar/Swiss 0.9179 0.9151 +0.31% +3.75% +0.9189 +0.9133 Sterling/Dollar $1.3791 $1.3840 -0.35% +0.94% +$1.3856 +$1.3768 Dollar/Canadian 1.2624 1.2534 +0.73% -0.85% +1.2643 +1.2522 Aussie/Dollar $0.7393 $0.7440 -0.63% -3.89% +$0.7468 +$0.7375 Euro/Swiss 1.0876 1.0860 +0.15% +0.64% +1.0881 +1.0845 Euro/Sterling 0.8591 0.8577 +0.16% -3.87% +0.8613 +0.8576 NZ $0.7107 $0.7134 -0.39% -1.04% +$0.7153 +$0.7087 Dollar/Dollar Dollar/Norway 8.6760 8.6775 -0.07% +0.98% +8.6900 +8.6495 Euro/Norway 10.2811 10.2625 +0.18% -1.78% +10.2997 +10.2588 Dollar/Sweden 8.5756 8.5649 +0.01% +4.63% +8.5852 +8.5428 Euro/Sweden 10.1638 10.1626 +0.01% +0.87% +10.1695 +10.1450 (Additional reporting by Saikat Chatterjee in London, editing by Mark Heinrich and David Gregorio) Our Standards: The Thomson Reuters Trust Principles.
