The euro fell another third of a percent against the dollar on Wednesday, as concerns around a resurgence in political risk to the single currency project drove its worst run of daily losses in almost two months.
The yen, however, was up another quarter of a percent at 112.12 per dollar, a move towards the perceived security of Japan pointing to the growth in concerns around global political risks and the Trump presidency that has dominated recent days.
The dollar was wobbling at the start of this week, a low wages number having quashed bets on a rise in U.S. interest rates in March and cooled expectations for the scale of monetary tightening this year.
Concerns over the impact on the world economy of President Trump's protectionism and immigration policy have also weighed on the greenback, along with the new administration's hints that it would prefer a weaker dollar.
Over the last two days, however, that has all played second fiddle to France's presidential election race and question marks over further international financial support for Greece. The dollar index had its best day in a month on Tuesday and it was up another 0.3 percent in early deals in Europe on Wednesday.
"The French political noise has brought the euro down and that has given the dollar a reprieve," said Gavin Friend, a strategist with National Australia Bank in London.
"Markets know that if Trump was to come out and start talking about tax reform and infrastructure spending, the dollar would go up. The dollar rose a long way at the end of last year, it has come back, now we are sitting around waiting for the next steer."
Having fallen as low as $1.0643 in Asian time, the euro traded 0.2 percent lower on the day at $1.0660 by 0850 GMT.
Uncertainty about the two rounds of the French presidential election on April 23 and May 7 drove the premium that investors demand for holding French over German government debt to its highest in more than four years.
