Is there any indication that the Euro rate is being politically manipulated?
In a recent (August 20, 2018) interview for Reuters about international politics, the president of the United States of America Donald J. Trump stated (emphasis mine):
ON CHINA AND EUROPEAN UNION CURRENCIES
“I think China is manipulating their currency, absolutely. And I think the euro is being manipulated also. ... And what they are doing is making up for the fact that they are now paying a lot for - hundreds of millions of dollars, and in some cases billions of dollars - into the United States Treasury - and so they’re being accommodated and I’m not, and I’ll still win.”
I am interested in the statement in bold: Is there any indication that the Euro rate is being politically manipulated ? If yes, how and in which direction ?
The main objective of the ECB is to maintain price stability in the euro area.
Also, it seems to me than all Euro-zone countries wouldn't agree about their favorite rate for the currency: for instance, a strong Euro reduces the cost of oil importations and protect investors' interests (which may suit countries with a positive balance of paiement, say, Germany) but a weak Euro will make economic production more competitive and help exportations and industries (which may suit countries with a high level of unemployment, for instance in the south of Europe).
