FRANKFURT — Amid myriad battles over trade agreements, concerns about the impending negotiations for Britain’s exit from the European Union, and political instability across the region, the eurozone continued to grow steadily but slowly in the third quarter.

Gross domestic product in the 19-nation currency union rose 0.3 percent in the three months through September, compared to the previous quarter, Eurostat, the office that compiles statistics for the European Union, announced on Monday. That was an unchanged growth rate from the previous quarter and corresponds to an annual rate of 1.4 percent.

Consumer prices in the 12 months through October rose 0.5 percent, up from 0.4 percent in the 12 months through September.

Economic growth and inflation were in line with analysts’ forecasts.

The indicators were closely watched not only for what they might say about the health of the eurozone economy, but for how they might affect decisions by the European Central Bank that can have a profound effect on financial markets.
