'The last thing the world needs today is a currency war,' Coeure said a panel at the World Economic Forum in Davos. 'We live in a world where exchange rates are not and should not be targeted for competitive purposes.'
'We see lots of volatility created recently by different statements and I think thats just not helpful,' Coeure said. 'Volatility is not helpful and if that would reach a point where it would create any unwarranted consequence for us, any unwarranted tightening for monetary policy, we would have to reassess.'
Coeure's comments come after U.S. officials earlier this week made the case for a weak dollar, sending the greenback tumbling to three year lows against the euro.
The currency volatility comes at an especially sensitive time for the ECB as it prepares to remove stimulus after nearly three years and 2 trillion euros worth of asset buys.
The stimulus has rekindled inflation but a strong euro will weigh on import prices, putting downward pressure on inflation and raising fears the ECB may not be able to end its bond buys as quick as hoped.
Despite the currency's strength, the euro zone economy is humming along and a key ECB survey published today suggests that price growth could even be faster in the coming years than earlier thought.
Headline inflation will continue to miss the ECB's target of almost 2 percent for years to come but projections in the survey were raised to 1.5 percent this year and 1.7 percent next year, underpinning ECB chief Mario Draghi's cautious optimism after the bank's policy meeting on Thursday.
Indeed, Coeure added that wages are now ticking up at least tentatively, suggesting that the euro zone may be nearing a tipping point with regard to inflation.
