NEW YORK, June 1 (Reuters) - The dollar fell broadly on Monday, tumbling to its lowest so far this year against both a basket of currencies and the euro, as optimism that the global economy is on the road to recovery boosted riskier assets.
Commodity-related currencies including the Australian and New Zealand dollars, which are considered to be higher risk, performed particularly well, hitting 8-month highs against their U.S counterpart as oil prices <CLc1> jumped and U.S. stocks rose <.SPX>.
The dollar pared some losses after a key measure of U.S. inflation rose more than expected and U.S. manufacturing data showed a slower contraction, but that failed to derail the day's overall trend. For more see [

In midmorning New York trade, the dollar index <.DXY> was down 0.2 percent at 79.045, having hit its lowest since mid-December at 78.586 earlier in the global session.
The euro gained 0.2 percent on the day to $1.4178 <EUR=>, having rallied as high as around $1.4246, its strongest since late December.
Among perceived higher risk currencies, sterling rose to its highest in seven months against the dollar at $1.6436 <GBP=D4>, while the Australian and New Zealand dollars hit eight-month highs of $0.8137 <AUD=D4> and $0.6520 <NZD=D4> respectively.
"This is a market that is in the process of selling the dollar against everything, buying commodities, and that should continue today," said Brian Dolan, chief currency strategist at Forex.com, Bedminster, New Jersey. "The move has taken on something of a self-fulfilling quality to it now."
The dollar did manage gains against the yen, climbing 1.1 percent to 96.31 yen <JPY=>. The yen is considered to have the least risk of all currencies and will fall against all currencies as risk tolerance rises.
EURO AND UK
Adding to optimism that the global economy may be over the worst of the recession, the final euro zone PMI manufacturing index climbed to a seven-month high of 40.7 in May, up from the provisional estimate of 40.5. [
]The UK manufacturing PMI was also stronger than expected, showing the slowest contraction in the sector in a year. [
]Earlier the Chinese PMI came in at 53.1 in May, and while this marked a fall from 53.5 in April, it was the third month in a row that the reading has been above the 50 level that separates expansion from contraction. [
]General Motors Corp <GM.N> filed for bankruptcy as expected, removing some uncertainty about the ailing U.S. auto industry. This helped risk appetite and weighed on the dollar. [
]Some analysts said the U.S. government's pledge of an additional $30 billion to rescue GM had inflamed long-running concerns about how Washington will fund its plans to help the struggling economy.
