NEW YORK, March 8 (Reuters) - The dollar rose against the euro on Tuesday amid fear that some euro zone states won't be able to withstand higher interest rates, though further gains will likely require more aggressive Federal Reserve policy.
Tough inflation talk from European Central Bank (ECB) President Jean-Claude Trichet last week had pushed the euro above $1.40, but recent credit downgrades for Greece and Spain reminded investors higher borrowing costs and a stronger currency would make it more difficult for debt-burdened countries to boost growth.
"The problem with the interest rate driven trade and Trichet's hawkish comments is that you have to see the other issues behind it," said John McCarthy, director of foreign exchange at ING Capital Markets in New York. "Higher rates will be devastating on the peripheral countries."
That helped pushed the euro down as low as $1.3860, extending a retreat from Monday's four-month peak of $1.4036. It last traded down half a percent at $1.3902 <EUR=EBS>.
"We're seeing continued euro/dollar selling from the real money community. It feels like the market wants to target 1.3880-1.3850," a London-based trader said.
The dollar also rose 0.6 percent at 82.73 yen <JPY=>.
Whether the greenback can extend gains against the euro will depend on whether the Fed hints at tighter monetary policy of its own. U.S. interest rates have been near zero for more than two years, and the Fed has poured even more money into the economy via direct purchases of Treasuries.
"Now the focus really shifts to the U.S.," said Paresh Upadhyaya, head of Americas G10 FX Strategy at BofA Merrill Lynch. "The Fed has sounded more hawkish lately, but will they continue to do so, will they start to detail an exit strategy? That's the big question."
The Fed holds its monthly policy meeting on March 15.
Following a break of the $1.3862 February peak, the next technical level is $1.3830, the low hit last Thursday before Trichet's hawkish comments. Then the euro could be heading toward $1.35, though investors say the euro is still supported by expectations the ECB may raise interest rates next month.
Euro zone countries are ironing out measures to resolve the region's debt crisis in time for a European Union summit March 24-25. They will meet at a preliminary summit on Friday, and any sign leaders are struggling to reach a consensus on a debt rescue fund could trigger more profit-taking in the euro.
"We have constructive expectations for reform of the EU financial stability fund. If those aren't realized, we could see negativity on the euro in the short term," said Carl Hammer, currency strategist at SEB in Stockholm.
Analysts at Credit Agricole said a lack of consensus later this month could trigger selling in the euro. It expects the single currency to trade at $1.27 by May.
Any sign the Fed is moving toward tighter policy should also boost the dollar against the yen, Upadhyaya said, though further unrest in Libya and elsewhere in the Middle East would push up oil prices further and limit dollar gains.
Oil prices <LCOc1> stabilized on Tuesday after Kuwait's oil minister said OPEC was in talks to boost oil production, although concerns remained about possible further supply disruptions due to unrest in the Middle East and North Africa.
An early slide in oil encouraged investors to sell the Swiss franc, which has gained broadly from safe-haven buying throughout the political uprising in Libya. For details, see [
