New figures show that growth in the euro zone's money supply picked up by slightly more than expected in June.
The European Central Bank said the annual growth rate stood at 10.9%, up from 10.6% in May. The news will reinforce expectations that the bank will raise interest rates further in the coming months.
The ECB's three-month moving average for growth, which is less subject to volatility, accelerated by 10.6% from April to June.
Money supply is measured by M3, which is the ECB's preferred indicator of medium-term inflationary trends in the euro zone economy.
