NEW YORK, Aug 9 (Reuters) - The dollar rose against major currencies on Monday as investors squared up positions a day ahead of the week's Federal Reserve monetary policy announcement.
Gains were limited by Friday's disappointing U.S. jobs data, which showed the economy continues to struggle. And analysts said markets are pricing in at least some form of modest easing when the Fed meets on Tuesday.
"Investors are likely to consolidate positions ahead of tomorrow afternoon's policy meeting," said Omer Esiner, chief market analyst at Commonwealth Foreign Exchange in Washington.
"While some risk of new policy action is already priced into the greenback's valuation, more stimulus would make a dollar recovery difficult in the near-term." For a preview of Fed meeting, see [
]The euro fell 0.4 percent to $1.3226 <EUR=EBS>, off a three-month peak of $1.3334 on Friday.
The euro added to losses after it failed to hold above the $1.33 level, which triggered automatic sell orders at $1.3250 and $1.3240, traders said.
Traders also kept a close eye on the yen, which rose to 85.02 yen versus the dollar on EBS on Friday, just shy of a 15-year peak of 84.82 yen hit last November. It was last up 0.4 percent at 85.84 yen <JPY=EBS>.
There were substantial automatic "stop loss" trades that would be triggered just under option barriers at 85 yen, potentially triggering a further slide, traders said. More stops were sitting below 84.82 yen, with option barriers at 84.75 yen seen rolling off later in the week, they said.
Markets fear Japanese authorities could intervene to weaken the yen so that strength does not derail a fragile, export-led recovery. Japan's finance minister expressed concern about yen strength on Monday. [

The anti-dollar bias in markets could keep the euro fairly buoyant in the near term, though profit-taking is expected as the euro approaches $1.35, analysts said.
That level almost coincides with a 50 percent retracement of the single European currency's fall from a November peak of $1.5145 to a four-year trough of $1.1876 hit in June.
It's possible Fed officials will add to a negative dollar bias on Tuesday if they "talk tough and make further hints about how they could intervene," said Andrew Wilkinson, senior analyst at Interactive Brokers Group in Greenwich, Connecticut.
Markets have speculated that the Fed could revive a plan to buy Treasury and mortgage debt to give the economy a boost, though Wilkinson said he thinks officials will hold off on taking action for now.
Data on Friday showed that overall U.S. payrolls fell by 131,000 in July. Private employment, a better gauge of labor market health, rose a modest 71,000, below forecasts for a gain of 90,000. [
