ECB's Lagarde: boosting euro's global status requires improvements to economy

FRANKFURT, July 4 (Reuters) - The European Central Bank President Christine Lagarde said on Friday that the European Union's economic systems need to become more efficient and more productive for the euro to draw level with the U.S. dollar's role as the world's foremost currency.

Speaking to German broadcaster ARD in an interview, Lagarde said "political leaders, the policymakers, need to engage to make our economy more productive and more efficient" before the euro can become the main global currency.
