NEW YORK, July 15 (Reuters) - The U.S. dollar fell to a one-low against major currencies on Wednesday, as blockbuster results from Intel and Goldman Sachs boosted confidence about corporate earnings and the economy.

Data showing the factories in New York state had nearly recovered from the recession in July also lifted spirits, undermining safe-haven demand for the dollar and pushing investors into higher-yielding currencies and equities.

The low-yielding yen struggled while the euro rose along with European shares <.FTEU3> and brushed off a slight annual decline in euro zone inflation. Increased risk appetite and a rise in the price of oil also lifted the Canadian dollar to a one-month high against its U.S. counterpart.

"Intel's earnings got things kicked off yesterday, and the U.S. data just improves the outlook, so all lights are flashing green for investors to take on risk," said Brian Dolan, chief currency strategist at Forex.com in Bedminster, New Jersey.

The euro was up 0.8 percent at $1.4078, near the day's high around $1.4103, the highest since July 2. It rose 0.9 percent to 131.95 yen while the dollar added 0.1 percent to 93.71 yen .

Sterling rose 0.7 percent to $1.6439 while an index that measures the dollar against six major currencies slipped to its lowest level since June 11 <.DXY>.

EARNINGS OPTIMISM, EURO AUCTIONS

Analysts said risk appetite was rising on speculation other U.S. firms may post solid second-quarter performance after reports from the two U.S. powerhouse firms exceeded forecasts.

"The market may be expecting more pleasant surprises rather than unpleasant surprises from earnings," said Steve Barrow, head of G10 currency research at Standard Bank in London.

The Australian and Canadian dollars , which tend to do well when investors' taste for risk grows, each rose about 1 percent against the greenback, with the latter hitting a one-month high at C$1.1193 per U.S. dollar.

JPMorgan Chase & Co will announce its results on Thursday, followed by Bank of America Corp and Citigroup Inc on Friday.

Euro bond redemptions this week may limit euro gains, however, said Antje Praefke, strategist at Commerzbank in Frankfurt. Roughly 60 billion euros of bond redemptions and coupon payments are scheduled this week, with about 36 billion euros due on Wednesday.

"If funds from those redemptions go back into euro assets, it won't be an issue, but if for example some of it goes back to Japan, euro-yen may fall," she said.

Elsewhere, data Wednesday showed China's currency reserves surged to $2.13 trillion last month. The yuan hit a two-week closing high at 6.8316 per dollar on Wednesday, the highest close since July 2. (Additional reporting by Tamawa Desai in London)
