The euro on Friday continued its downward trend against the dollar following European Central Bank chief Mario Draghi's comments a day earlier that signaled further monetary easing could be on deck for the euro zone.
Europe's common currency checked in below $1.10, hitting a low against the dollar not seen since early August, and was down 3.05 percent versus the greenback for the week. It was the euro's worst weekly fall since May.
The euro also fell to a one-month low against the yen, down 1.4 percent for the week, its largest weekly percentage fall in six weeks.
ECB President Draghi on Thursday said the bank could accelerate its bond purchases, extend its asset-buying program, and further cut its deposit rate, currently at -0.2 percent.
"Draghi not only delivered, but he exceeded many dovish expectations," said Omer Esiner, chief market analyst at Commonwealth Foreign Exchange in Washington. "The risk of more monetary stimulus in the euro zone is broadly negative for the euro."
