Calls for higher inflation targets in Japan sent the greenback rising as did softer-than-expected German output data.
In U.S. trading on Wednesday, EUR/USD was down 0.20% at 1.3055.
German industrial production rose 0.2% in November, according to official data, missing market expectations for a 1.0% increase.
German industrial production fell 2.9% on year in November, in line with expectations.
On Tuesday, the German government reported that factory orders fell 1.8% in November, outpacing market expectations for a 1.4% decline thanks in part to slumping overseas demand for the country's goods and services.
Elsewhere, final data showed that the eurozone economy contracted 0.1% in the third quarter, in line with preliminary estimates as well as market expectations.
The greenback saw added safe-haven demand as markets began to brace for fourth-quarter earnings, which have already begun hitting the wire, and for congressional debates over terms to raise the U.S. government's debt ceiling.
The U.S. government will hit its USD16.4 trillion borrowing limit likely by the end of February, and Congress must lift the spending ceiling in order to prevent defaults on government obligations.
When the government last hit its debt ceiling in 2011, lawmakers waited until the final hour to lift it, roiling markets in the process and fueling strong safe-haven demand for the greenback shortly afterwards.
Fears of a repeat performance in February sparked cautionary dollar demand on Wednesday.
