If the future of the euro zone does indeed depend on political cooperation between France and Germany, then economic divergences between the two countries should be a cause for concern. These divergences need to be analysed, with particular attention to three specific areas: the unemployment rate, the trade balance and the public debt. Germany’s unemployment rate is falling steadily; in June it was under the 5% mark, which represents almost full employment, whereas the French rate is over 10%. Germany’s low unemployment rate does not however reflect strong consumption by German households, but rather the country’s export capacity. While France continues to run a negative trade balance (importing more than it exports), Germany is now the world’s leading exporter, ahead of China, with a trade surplus that will run close to 8% in 2015. As for the public deficit, it will be around 3.8% in France in 2015, while Germany is now generating a surplus. This has impressive consequences for the way the public debt is changing in the two countries. In 2010 they were similar, at around 80% of GDP, but in 2014 Germany’s public debt fell below 75%, and is continuing to decline, while France’s debt has continued to grow, and has now hit 97%. This kind of gap is unprecedented in recent times, and is fraught with mounting tension over the conduct of monetary policy.
