Draghi also sought to play down any talk of currency wars as central banks provide cheap money to help revive their economies. The euro fell 0.2 per cent against the US dollar.
"Most of the exchange rate movements that we have seen were not explicitly targeted, they were the result of domestic macro-economic policies meant to boost the economy," Draghi said. "In this sense, I find really excessive any language referring to currency wars."
The Japanese yen slid fell 0.5 per cent against the US dollar, and weakened 0.4 per cent against the euro, after Group of 20 finance ministers and central bank governors refrained from asking countries to avoid targeting exchange rates.
"There's renewed selling pressure on the yen and it's a reaction to the G-20 statement," Adam Myers, head of foreign-exchange strategy at Credit Agricole Corporate & Investment Bank in London, told Bloomberg. "Everyone has woken up to the realisation that the G-20 couldn't criticise Japan when many other countries are manipulating their own currency."
One development that could help the yen is the naming of a new governor for the Bank of Japan. Reuters says that Prime Minister Shinzo Abe may nominate former financial bureaucrat Toshiro Muto as early as this week. Masaaki Shirakawa will give up the post on March 19.
Commodities including nickel, copper and aluminium weakened amid concern about the pace of growth in China, following a report showing disappointing retail sales.
