LONDON, Nov 15 (Reuters) - The euro consolidated gains at a three-week high on Wednesday as investors grew optimistic about the single currency’s outlook with growing doubts about the prospects of the U.S. tax plan also underpinning gains.
With growth from the economic bloc exceeding the United States in the third quarter, led by economic powerhouse Germany, investors were becoming more comfortable in holding risky assets in Europe.
“The growth story in Europe is reasserting themselves and we are starting to see some doubts creep in on the prospects of the U.S. tax plan,” said Timothy Graf, head of macro strategy EMEA at State Street Global Markets in London.
The single currency punched through a key technical level of $1.1734 on Tuesday and extended gains on Wednesday to rise 0.4 percent at $1.1853 against the dollar.
On a two-day rolling basis, the euro was set to stage its biggest rise in nearly six months.
Over the last few sessions, unhedged purchases of European stocks have picked up noticeably after declining in October.
The euro’s gains was also partially a dollar weakness story as the single currency’s gains was largely muted against the crosses, especially the Japanese yen
The euro’s gains were also bolstered by concerns that an ambitious U.S. tax plan may face headwinds even as financial markets have priced in more interest rate hikes next year.
U.S. Senate Republicans on Tuesday linked repealing a key component of Obamacare to their ambitious tax-cut plan, raising new political risks and uncertainties for the tax measure that financial markets have been monitoring closely for months.
The dollar index fell 0.3 percent to 93.553 on Wednesday as investors awaited U.S. consumer inflation data for October, due later on Wednesday, that is expected to show a marginal increase in consumer prices.
“The dollar is getting hit against the euro and the yen and the strong data out of Europe is definitely a factor with some investors bailing out of the long dollar trade,” said Alvin Tan, an FX strategist at Societe Generale in London.
