The U.S. dollar and the Japanese yen lost ground Wednesday as positive second-quarter earnings surprises dented safe-haven demand for the low-yielding currencies.

Major currency pairs remain range-bound, but continue to take short-term trading cues from the equity markets, traders said.

U.S. stock index futures pointed to a higher opening on Wall Street. European equities were higher, while Asian stocks gained ground early Wednesday.

The dollar index (DXY), which tracks the greenback against a trade-weighted basket of six major rivals, was at 79.643, compared to 80.185 in North American trade late Tuesday afternoon.

The tone in equity markets was set by chip giant Intel (INTC), which rose 6% in Frankfurt. Intel reported a second-quarter loss after the U.S. market close Tuesday, with results hit by a fine from the European Union. Excluding the penalty, however, results beat forecasts.

Financial markets will continue to digest Tuesday's releases, while looking forward to earnings from J.P. Morgan Chase (JPM), Citigroup (C) and Bank of America (BAC), later this week, said Jessica Hoversen, a currency strategist at MF Global Research in Chicago.

While strong earnings from Goldman Sachs (GS) on Tuesday morning and the Intel earnings after the close encouraged risk taking, results from Yum Brands (YUM) and Altera (ALTR) were less positive, she noted.

"The greater driver of the trade will be the outlook for growth," Hoversen said.

The euro was bought $1.4058, up from $1.3933 late Monday.

Annual consumer price inflation in the 16-nation euro zone fell 0.1% in June after a flat reading in May, marking the first time inflation had turned negative since the launch of the euro a decade ago, the European Union statistics agency Eurostat confirmed Wednesday.

The figure matched a preliminary estimate released last month.

The euro posted little significant reaction to the data.

The British pound, meanwhile, rose 0.4% versus the U.S. dollar to trade at $1.6387, tracking the stronger tone in financial sector stocks.

The Office for National Statistics painted a mixed but generally gloomy picture of the U.K. labor market. The data showed the number of people claiming jobless benefits rose at its slowest pace in more than a year in June, but also showed the overall unemployment rate rose to its highest level since January 1997 in the three months ending in May.

"Sterling initially softened on the news, but cable [the British pound vs. the U.S. dollar] continues to hold above last night's close and well within the confines of its range," said Jane Foley, research director at Forex.com.

Currency markets had a muted reaction to news that the Bank of Japan decided at its two-day policy meeting that concluded Wednesday to extend its special liquidity-boosting measures for an additional three months to support the recovery.

The dollar was at 93.50 yen, compared with 93.24 yen Tuesday

The Bank of Japan left its overnight call rate unchanged at 0.1%, as was widely expected.
