* Dollar up on short-covering as Fed decision looms
* Market deeply divided on whether Fed will ease
* BOJ stands pat on monetary policy as expected

TOKYO, Aug 10 (Reuters) - The dollar staged a rebound against major currencies on Tuesday as traders pared short positions on looming uncertainty over whether the U.S. Federal Reserve will start a new phase of quantitative easing to deal with a slowing economy.
Much uncertainty surrounds the Federal Reserve's policy meeting on Tuesday with the market deeply divided over what the Fed might do, beyond a rough agreement that it will sound more cautious on the recovery.
"I have a feeling that the market has got carried away with the idea of the Fed easing. It seems as if most traders are expecting the Fed to say it will reinvest maturing bonds at least," said a trader at a Japanese bank.
A Ried Thunberg/ICAP poll of money managers found that 52 percent thought the Fed would take no new action on policy, while 48 percent believed it would at least hint at new steps.
Such steps may include anything from a promise to consider more quantitative easing; to reinvesting money from maturing debt into Treasuries or MBS; to cutting interest paid on excess reserves; to buying financial assets outright. [
]"If the Fed does take action today and U.S. interest rates fall, that is likely to lead to dollar-selling," said Hiroshi Maeba, manager of forex at Nomura Securities.
The crucial policy announcement from the Fed is expected around 1815 GMT.
Given the uncertainty, speculators trimmed their short dollar positions. The euro fell 0.5 percent from late U.S. trading on Monday to $1.3148 <EUR=>, pulling away from a three-month peak of $1.3334 hit on Friday on trading platform EBS.
The euro's decline gained steam after it fell below trendline support on hourly charts near $1.3200, with stop-loss orders also adding to the euro's drop.
The pullback came despite upbeat euro zone data, with investor morale surging [
] and German exports up strongly. [ ]The yen was the exception to the dollar's broad rebound on Tuesday and edged up slightly against the greenback. Traders cited talk of fund repatriation by Japanese investors related to coupon payments of U.S. Treasuries due in mid-August.
The Bank of Japan kept interest rates steady at 0.1 percent and held off on new policy steps, in a decision that was in line with market expectations. [
]The dollar slipped 0.1 percent to 85.83 yen <JPY=>, still some distance from last Friday's eight-month low of 85.02 yen.
Market players said there are substantial stop-loss orders just under options barriers at 85 yen, with more stops sitting below 84.82 yen. A fall below 84.82 yen would take the dollar to a 15-year low against the yen.
Traders think the yen will eventually test these levels as Japan is seen unlikely to intervene to curb the yen unless dollar/yen falls to around 80 yen. [
]Japanese Finance Minister Yoshihiko Noda declined to comment on intervention. He also said the recent market moves are somewhat onesided, but that produced no market response. [
]Sterling <GBP=D4> fell 0.6 percent to $1.5809 after data showed British house prices fell in the three months to July for the first time in a year and that retail sales growth slowed sharply in July. [
