Dollar prices edged up from four-month lows against the yen on Thursday, but gains were capped by U.S. President Donald Trump's struggle to push through a healthcare bill. The U.S. currency has struggled this week as growing doubts over Trump's ability to push through with economic and tax policies triggered broad risk aversion and buffeted equities. U.S. Treasury yields declined in turn, eroding the dollar's interest allure. Financial markets' immediate focus is on whether Trump can gather enough support at a vote later in the day to pass a bill to rollback Obamacare, one of his key campaign pledges. Trump's plan faces resistance from some conservative Republicans who view it as too similar to Obamacare, and from moderates concerned it will hurt some voters. "The vote on Obamacare is a litmus test for Trump. If he can't push through the bill on Obamacare, it would further damage stocks. It also raises the risk of his other policies, like tax cuts, being delayed," said Masafumi Yamamoto, chief forex strategist at Mizuho Securities in Tokyo. "So today's vote is of main importance to the currency market." The dollar was up 0.15 percent at 111.350 yen, enjoying a bit of respite after sliding to a four-month low of 110.735 on Wednesday, when it fell for the seventh straight session. With global equities buffeted by risk aversion this week -Wall Street on Tuesday suffered its worst day since Trump's election, the dollar has struggled notably against the yen, often sought by investors due to its perceived safe-haven status in times of market tumult. Its safe-haven status was also seen helping the yen as Tokyo dealt with a political scandal involving Prime Minister Shinzo Abe, facing questions about his ties to a nationalist school involved in a murky land deal. "If the situation over the prime minister's dealings with the school remains unresolved, the yen could gain further against the dollar," said Yukio Ishizuki, senior currency strategist at Daiwa Securities. The euro was little changed at $1.0792 after advancing to a seven-week high of $1.0825 overnight. The common currency has been supported this week on growing expectations of a tightening in European Central Bank monetary policy this year, and on bets that the anti-euro candidate Marine Le Pen will be defeated in the French presidential elections. The dollar index against a basket of major currencies was up 0.1 percent to 99.751 after its descent to a seven-week trough of 99.457 the previous day. The pound was effectively flat at $1.2482 and in reach of a one-month high of $1.2507 scaled on Wednesday. Sterling briefly dipped on Wednesday following what the police described as a marauding terrorist attack in London, but it recovered when there were no reports of other separate incidents. The Australian dollar was down 0.3 percent at $0.7657. The Aussie has lost about 0.6 percent this week, after a stellar two percent gain last week, as investors sought safe havens such as the yen, bonds and gold. Also working against the Aussie was a steep fall in the price of iron ore – the country's top export earner. The New Zealand dollar was steady at $0.7041. Source: Reuters
