The volume of loans to private businesses and households declined by 1.1 percent in October compared with the same month in 2013, a slightly lower rate than the drop of 1.2 percent recorded in September, the ECB said in a statement.
The long and deep financial crisis in the 18 countries that share the euro has squeezed lending, thus dampening economic activity.
The overall eurozone money supply grew 2.5 percent in October from a year earlier, the same rate of change as in September.
