These ups and downs in exchange rates, and thus also in terms of price competitiveness, are entirely within the realm of normal fluctuations. The fact that Germany’s economy is highly competitive certainly isn’t the outcome of manipulative policy, either.

Additionally, German enterprises are competitive because they are excellently positioned in global markets and offer innovative products.
