The ECB also said is M3 measure of money circulating in the euro zone, which is often an early indicator of future economic activity, grew by 5.0 percent in June, in line with the previous month.
But lending to companies fell by 0.2 percent in June. This was a slower pace of decline for the 11th month in a row, but still suggested most of the ECB's largest is going to consumers not companies.
In its report on the euro zone, the IMF said that the bloc was getting stronger thanks to lower oil prices, a weaker euro and central bank action, but that medium-term prospects were for an average potential growth of just 1 percent.
The IMF said euro area gross domestic product should accelerate to 1.7 percent next year from 1.5 percent in 2015, with inflation of 1.1 percent from zero.
IMF's Pradhan warned, however, that "a chronic lack of demand, impaired corporate and bank balance sheets, and weak productivity continue to hold back employment and investment."
Potential growth, at an average of only 1 percent over the medium term, was well below what is needed to reduce unemployment to acceptable levels in many countries, it said, adding that the euro area was vulnerable.
Reforms were also needed to improve labor markets and productivity. "In the euro area, the important area is structural reforms. This is where the euro area, when compared to OECD countries, for example, is lagging behind,"
