LONDON, Feb 11 (Reuters) - Worries about the health of the global economy, highlighted at the weekend's meeting of Group of Seven, boosted the yen on Monday, while the euro benefited from hawkish policymaker comments.
European Central Bank President Jean-Claude Trichet stressed that there was no call to move rates up or down at last week's policy meeting while Governing Council member Axel Weber told a German newspaper the ECB had not relaxed its view on inflation risks.
The comments seemed to be aimed at toning down markets' interpretation last week that the ECB was opening the door for future monetary easing by dropping wording about pre-emptive action against inflation while warning of downside growth risks.
The euro clawed back some of the previous week's losses, but money markets were still pricing in nearly 100 basis points of easing by year-end.
Another positive for the euro came from comments by OPEC Secretary General Abdullah al-Badri over the weekend that OPEC may switch to pricing oil in euros rather than dollars.
"Every time that story hits the wires, we get a knee-jerk reaction in euro higher, but if you look at the details, there are no immediate plans, so I don't expect it (currency reaction) to last very long," said Adam Myers, market strategist at Credit Suisse.
By 0831 GMT, the euro was up 0.4 percent at $1.4564 <EUR=>. But that erased only a fraction of last week's 2 percent slide -- the currency pair's biggest weekly fall in 1-1/2 years.
The euro fell a third of a percent to 155.23 yen <EURJPY=>, while the dollar was down 0.7 percent at 106.59 yen <JPY=>.
The Japanese currency benefited from a risk averse mood, with worries about global growth and falling equity markets prompting currency investors to exit risky carry trade bets funded by cheap borrowing in the yen.
G7 finance leaders, meeting in Tokyo, said the crumbling U.S. housing market had wounded the world economy and conditions may worsen as debt-laden banks clamp down on credit.
"One message that came out of the G7 statement over the weekend is that global growth is expected to slow, and it will be a much broader slowing than originally anticipated, so that should benefit the yen," said Myers at Credit Suisse.
On currencies, the G7 largely repeated the language in the previous statement, saying that exchange rates should reflect economic fundamentals. But they tweaked comments on China's yuan to say "we encourage" the need for greater appreciation of the currency instead of "we stress", which was used last time.
HAWKISH RBA HELPS AUSSIE
The Australian dollar firmed as the central bank warned it would likely need to raise interest rates again to restrain quickening inflation, even as it reduced its growth forecasts.
The Australian dollar <AUD=> rose 0.9 percent to a one-week high of US$0.9043, supported by growing market expectations the central bank will raise rates again at its meeting in March, after boosting them to an 11-year peak of 7 percent last week.
The Reserve Bank of Australia raised its inflation forecasts in a policy statement on Monday, saying it saw considerable risk that inflation would remain uncomfortably high.
"The RBA's (statement) ... was hawkish and suggests that a follow up rate hike in March and possibly beyond cannot be ruled out unless domestic demand starts to show some signs of moderation," RBC Capital Markets said in a note, recommending long bets on the Australian dollar versus its New Zealand counterpart <AUDNZD=R>.
Monday's data calendar is relatively light, but a meeting of EuroGroup finance ministers in Brussels may yield some comments on currencies, interest rates or the economy. (Editing by Mike Peacock)
