NEW YORK, Feb 8 (Reuters) - The euro remained under pressure on Friday and on track for its biggest weekly fall versus the dollar in 1-1/2 years amid growing expectations the European Central Bank will cut interest rates later this year.
The ECB kept its key interest rate at 4 percent on Thursday but President Jean-Claude Trichet dropped a threat to act preemptively against rising prices and accepted that unusually high uncertainty in markets may hurt the real economy.
Investors were reluctant to take big currency positions before a weekend meeting of Group of Seven finance officials in Tokyo. The summit may yield some comments on currencies, though foreign exchange is not expected to take center stage.
"It became clear this week that the economic slowdown has been moving East and that Europe is not insulated," said Mark Meadows at Tempus Consulting in Washington D.C. "The euro suddenly came under pressure and it may continue so for a while."
By early morning in New York, the euro was little changed at $1.4491 <EUR=>, down around 2.2 percent since Monday and on track for its biggest weekly fall since June 2006. The euro was down 0.15 percent at 155.50 yen <EURJPY=>, while the dollar edged down 0.2 percent to 107.28 yen <JPY=>.
Trade was relatively quiet, as many Asian players are away for the Lunar New Year break. Financial markets in Tokyo will be closed on Monday for a national holiday.
Sterling was up 0.2 percent versus the dollar <GBP=> and euro <EURGBP=>, recovering some of Thursday's losses sustained after the Bank of England cut rates by 25 basis points to 5.25 percent and signaled that it would likely stick with a path of gradual monetary easing.
Although the euro is now some 5 cents -- or 3 percent -- below last November's record high versus the dollar, it is still more than 10 percent higher than a year ago and on the ECB's trade-weighted basis it is holding just below all time peaks set in January <EUREER=ECBF>.
Many European officials have expressed concern about the euro's strength, with French trade minister Henri Novelli saying on Friday that lower interest rates in the region would help companies struggling under the impact of a stronger currency. This view has been backed by weak export data from France and Germany this week.
"There's clearly a perception that the ECB now has an easing bias but they are unlikely to cut rates as early as March," said Michael Klawitter, FX strategist at Dresdner Kleinwort in Frankfurt.
However, European officials are not expected to secure the support of the other Group of Seven countries for some kind of joint statement on the euro's strength or dollar's weakness.
"The reality in fact is for a rerun of October's communique, i.e. no explicit mention of major currencies but calls for yuan flexibility to increase. A greater focus will be put on the risks to global growth," said ING in a client note.
A G7 source said discussions on foreign exchange rates will be less important this time than those on policy responses to the deteriorating international economic climate.
In October, the finance ministers stressed the need for an accelerated appreciation of the Chinese yuan while repeating that excess volatility and disorderly movements in exchange rates are undesirable for economic growth. (Additional reporting by Simon Falush in London; Editing by Andrea Ricci)
