The euro dropped over half a percentage point and hit lows last seen in July 2017 on Friday after United States President Donald Trump tweeted about the currency.
Trump blamed the Federal Reserve earlier in the day, saying US exporters are suffering because of the strong dollar.
The euro hit a daily low of 1.09870 compared to the dollar and was trading 0.53% lower compared to the US currency at 11:10 am ET, changing hands at 1.00974.
