Yes, there is a maximum allowed limit in the Maastricht treaty. Germany has been systematically breaking the rules. https://www.intereconomics.eu/contents/year/2018/number/3/article/on-current-account-imbalances.html https://www.intereconomics.eu/contents/year/2018/number/3/ar... "The rules established under the EU’s macroeconomic imbalance procedure (MIP)define a ceiling for current account surpluses of six per cent of GDP and stipulate that the three-year average for a country’s current account surplus should not exceed this ceiling.2 However, Germany has been running surpluses in excess of this figure for many years. Its most recent three-year average is eight per cent of GDP, while the 2016 figure was even higher, at 8.5%."
