"There is no particular interest in cutting rates by a few cents if it only impacts Germany or core countries," Noyer, who also heads the Bank of France, told Wall Street Journal in an interview.

The southern European countries mired in the debt crisis have not reaped full benefits of the record low interest rates, with the rates consumers and firms having to pay still clearly above the ones in core euro zone countries.

Noyer also said that the excess liquidity levels remained "very significant" even after upcoming LTRO repayments. Banks have the opportunity to pay back early 3-year loans on a weekly basis if they so wish.

They took more than 1 trillion euros in ultra-long term funds from the ECB roughly a year ago.

Commenting on the rising euro, he said that it might push inflation lower.

"It is clear that if there are changes in foreign exchange it will influence our inflation outlook," he told the newspaper.

At the same time, he said he expected that the common currency would not rise further, following the statement by 20 industrialised nations that they commit to foreign exchange rates being determined by markets.

"I think the G-20 message will help currencies to stay in line with economic fundamentals and from this point of view there is no reason for the euro to be pushed higher," Noyer said.
