The dollar dipped to a four-day low against major currencies on Friday and the euro rose on the recent raft of robust data.
Traders were looking to US inflation data due next week to provide clues on the US Federal Reserve's likely interest rate policy.
The dollar index - which measures the greenback against a basket of six major currencies, the euro the heaviest weighted among them - inched down by a quarter of a per cent as the euro hit $1.1180, its highest since Monday.
The European Central Bank is deciding when and how quickly to wind back its expansive quantitative easing (QE) programme.
“With the debate over ECB QE policy heating up, expect the euro to be much more sensitive to data surprises,” wrote ING currency strategist Viraj Patel in a research note.
UBS currency strategist Daniel Trum, however, in Zurich, said currency markets were not showing great sensitivity to data at the moment unless they were particularly weak or strong. He said the euro had been lifted this week by consumer confidence hitting a 16-year high in June.
The dollar peaked at a one-month high on Tuesday after the Federal Reserve hiked interest rates last week and left the door open for further monetary tightening later in the year. But it has been stuck in a tight range since, awaiting fresh catalysts.
“For the dollar were in a waiting game until September," said Trum. “In our view theyll then hike interest rates but then start to talk about the inflation rate - if that doesn't start to go up then future hikes will become more difficult.”
US data due next week include the June consumer confidence indicator, pending home sales, crude oil inventories, revised first quarter GDP and the PCE price index.
“While most US indicators bear watching, what really matters for the dollar are wages and inflation-related data, culminating with the non-farm payrolls in two week's time,” said Makoto Noji, a senior strategist at SMBC Nikko Securities.
Commodity-linked currencies held to significant gains made on Thursday following a rebound in crude oil prices from 10-month lows. The Canadian dollar was flat at C$1.3223 per US dollar after rallying 0.75 per cent on Thursday.
Exactly a year after Britain voted to leave the European Union, sterling was almost half a percent stronger on the day at $1.2738, with some investors betting the Bank of England could raise interest rates as soon as August.
In the year since the vote, the pound has fallen more than 15 per cent against the dollar and almost 13 per cent versus the euro.
