NEW YORK, July 30 (Reuters) - The U.S. dollar fell against major currencies on Thursday as a sharp rally in world stock and commodity markets on optimism about the global economy eroded safe-haven demand for the greenback.
On Wall Street, the Dow industrials <
> jumped after a string of stronger-than-expected corporate results, while European shares < > closed at their highest level in nearly nine months and oil prices <CLc1> advanced above $66 a barrel.The increase in risk appetite also drove the yen sharply lower and helped the euro and currencies perceived as higher-risk recoup some of the previous day's sharp losses.
"The dollar was seeing selling because of the reversal of the safe-haven (flow) with the rally in stocks," said Chris Gaffney, vice president at EverBank World Markets, in St. Louis, Missouri. "The general consensus and feeling in the markets is that things have bottomed and we're starting to grow now."
The dollar's losses were limited, however, with many investors staying on the sidelines ahead of key data on U.S. gross domestic product for the second quarter on Friday.
The economy is forecast to have contracted by 1.5 percent in the second quarter after a fall of 5.5 percent in the first three months of the year, according economists polled by Reuters. <ECI/US>
"People are looking ahead to (Friday's) GDP data. That should be a pretty important piece of data for the recovery/recession debate that seems to be ongoing," said Adam Fazio, currency strategist at CIBC World Markets in New York.
He said CIBC is looking for "a much worse reading," and should the GDP data disappoint, the dollar could see "further strength" as investors look for safe-haven investments.
In midday trading in New York, the ICE Futures U.S. dollar index, a gauge of the greenback's performance against six major currencies, fell 0.5 percent to 79.270 <.DXY>. It hit a 2009 low of 78.315 on Tuesday, before staging a strong rebound on Wednesday.
COMMODITY CURRENCIES RALLY
The euro rose 0.3 percent to $1.4076 <EUR=>, rebounding from a two-week low near $1.40. The single euro zone currency briefly pared gains after the International Monetary Fund said that the euro's exchange rate looks "somewhat on the strong side relative to its fundamentals."
Based on exchange rate developments from Feb. 25 to March 25, the IMF report said, "estimates place the euro's overvaluation in a range of 0-15 percent." For story, see [
]The dollar rose 0.6 percent to 95.64 yen, extending gains after government data showing a drop in continuing claims boosted optimism about the U.S. labor market.
The number of U.S. workers filing new claims for jobless benefits rose slightly more than expected last week, but a gauge of underlying labor trends fell for a fifth straight week, the Labor Department said. [
]"The continuing claims component was getting better so that bodes well for the U.S. economy going forward," said Matthew Strauss, senior currency strategist at RBC Capital Markets in Toronto. "That has provided support for the dollar against the yen."
Perceived higher risk and commodity-linked currencies such as the Australian and Canadian dollars jumped, buoyed by gains in Chinese shares and a recovery in oil prices.
The Australian dollar gained 1.3 percent to $0.8270 <AUD=>. The U.S. dollar fell 0.8 percent against the Canadian dollar to C$1.0816 <CAD=>.
Elsewhere, a survey by Nationwide showing UK house prices rose 1.3 percent this month boosted sterling, which rose 0.7 percent against the dollar <GBP=> to $1.6493 and hit one-month high against the euro <EURGBP=>. [
