FOREX-Yen falls before weekend elections; dollar holds gains
* Polls show Abe's ruling bloc to win in Sunday's elections
* Yen falls to seven-week low against euro
* Dollar climbs, U.S. initial jobless claims fall sharply
NEW YORK, July 18 (Reuters) - The yen fell broadly on Thursday, hitting a seven-week low against the euro, as traders bet Japan's upper house elections on Sunday would strengthen Prime Minister Shinzo Abe's position and his stimulus plans. Opinion polls show Abe's ruling bloc on track for a big win, which will give Abe more freedom to push forward his agenda to revive the economy through aggressive monetary easing and hefty government spending. The dollar and euro have gained about 15 percent against the yen so far this year on expectations of aggressive easing in Japan. But the rally has lost momentum since the dollar hit a 4-1/2-year high of 103.73 yen in late May. "Japanese elections over the week-end should encourage more outflows out of Japan," said Sebastien Galy, foreign exchange strategist at Societe Generale in New York. The dollar gained 0.7 percent to 100.28 yen, having reached a session peak of 100.37 yen, according to Reuters data. Hedge funds were cited as buyers of dollar/yen with stop-loss buy orders layered at 100.50 and 101.00 yen, traders said. The euro rose as high as 131.47 yen, the strongest since the end of May, before pulling back to 131.19 yen, up 0.4 percent. "Anything that will strengthen Abe's position will be positive for the Nikkei and dollar/yen," said Beat Siegenthaler, currency strategist at UBS. "The yen has not been the focus of late, but this could embolden investors and have the potential to trigger weakness." Morgan Stanley said in a note that a break above 101.55 yen for dollar/yen could signal a return to the upward trend. The dollar held on to broad gains as investors bet U.S. economic data would support plans by the Federal Reserve to move away from ultra-loose monetary policy soon. It extended gains after data showing the number of Americans filing new claims for jobless benefits dropped more than expected last week to its lowest level in four months, a possible sign that hiring could pick up in July. Later in the session, U.S. leading indicators and the Philadelphia Fed business conditions index will be released. In Congressional testimony on Wednesday, Fed Chairman Ben Bernanke said the central bank still expected to start scaling back its bond purchase program later this year, but left open the option of altering that plan if the economic outlook changed. Bernanke is seen likely to stick to Wednesday's themes when he testifies before the Senate Banking Committee on Thursday. The dollar index, which tracks the greenback versus a basket of six major currencies, rose 0.3 percent to 82.929, staying above a three-week low of 82.342 set on Wednesday. The euro fell 0.4 percent to $1.3079. "We are bullish dollar but we are getting mixed signals from the Fed," said Peter Kinsella, currency strategist at Commerzbank. "Fed tapering will be very data-dependent and if we get good jobs data next month, then we can expect stimulus withdrawal by September. Otherwise expectations of tapering will be pushed back to December. This uncertainty should keep it rangebound." The dollar had been boosted by higher U.S. yields but doubts over when the Fed will start withdrawing stimulus has kept it clear of three-year highs struck on July 9.
