Around 9 p.m., the euro was up 0.13% against the greenback, at $1.1830.

The euro rose against the dollar on Friday, while the pound limited its losses a little but continued to suffer from Brexit.

Around 19:00 GMT (21:00 in Paris), the euro was up 0.13% against the greenback, at 1.1830 dollar.

The European currency had appreciated sharply on Thursday in the wake of a meeting of the European Central Bank, before erasing a good part of its gains.

She had notably benefited from the words of the president of the institution Christine Lagarde concerning the strength of the euro, which weighs on inflation. In its view, there is no need to act at this stage.

"There were, without a doubt, some investors who expected the ECB to comment more explicitly on the appreciation of the euro and even signal that a future strengthening was not desirable," explained Derek Halpenny, analyst for MUFG.

But according to him, in the words of Mrs Lagarde, there was also "the message that a stronger opposition (to a strong euro, Editor's note) could be created, especially if the outlook deteriorates and inflation falls", even if this has not been enough to temper the ardor of the single currency.

The pound, for its part, had started the session slightly higher against the greenback, before making the roller coaster.

It fell 0.10% against the dollar to $1.2792. Against the single European currency it gave up 0.23% to 92.48 pence for a euro, after falling to 92.92 pence for a euro, a level more seen since March.

On Thursday, the pound had collapsed, losing 1.52% and 1.62% respectively against both currencies, extremely important levels for the foreign exchange market.

Discussions on the future post-Brexit relationship took a dramatic turn this week, with London deciding to touch the Brexit deal reached last year, much to Brussels' chagrin.

On Thursday, the United Kingdom ruled out backtracking, despite threats of legal action from the European Union.

But the latter "did not say that it was withdrawing from the negotiations", which is a positive sign, said Neil Wilson, analyst for Markets.com.

However, all analysts agree that the risk of "no deal" has increased at the end of these three days of negotiations that have not allowed any major progress.

"Brexit has become appalling again," said Jasper Lawler, an analyst at London Capital Group.

The two sides have until the end of the year to reach an agreement.
