NEW YORK, March 10 (Reuters) - World stocks and the euro fell on Thursday as a downgrade of Spain's credit rating added to worries over the euro zone debt crisis, while an unexpected Chinese trade deficit fueled global growth concerns.
Brent oil prices <LCOc1> dipped below $114 a barrel on data showing China posted in February its largest trade deficit in seven years. The country's exports, a gauge of global economic activity, suffered a larger-than-expected impact from the Lunar New Year holiday. For details, see [
].Copper prices also fell on data showing China's imports of commodities declined. The retreat in oil prices was limited, however, as forces loyal to Libyan leader Muammar Gaddafi assaulted the eastern oil town of Ras Lanuf, sparking worries about damage to the oil infrastructure. [
]U.S. stocks fell around 1.5 percent as higher-than-expected claims of unemployment benefits in the United States added to the economic concerns.
"Overseas issues continue to play a role in U.S. markets. The situation in Europe isn't complete, the market continues to have concerns about sovereign credit," said Subodh Kumar, chief investment strategist at Subodh Kumar & Associates in Toronto.
"Markets have been hoping that China would lead the recovery, but when you put this (U.S.) data with slower growth out of China, the idea that everything looks normal is going away."
China exports grew in February from a year earlier but well short of forecasts.

The euro <EUR=> fell 0.76 percent to $1.3802 after Moody's downgraded Spain to Aa2 from Aa1, warning of further cuts to the country's credit ratings. [
]The move comes a few days after Moody's downgraded Greece by three notches, fueling negative sentiment towards struggling euro zone sovereign borrowers on the eve of a summit of the currency bloc. [
]"This (rating cut) is a reminder they need to come up with a comprehensive, believable solution by the end of the month," said Colin Ellis, chief economist at BVCA.
"With the level of uncertainty at the moment, pressure on yields will build up in the next two weeks... and you could continue to see spreads going wider. But I'm not expecting any spikes like those pre-Greece or pre-Ireland (bailouts)."
The U.S. dollar strengthened broadly, with the U.S. Dollar Index <.DXY> up 0.7 percent. That contributed to a fall in oil and other commodity prices, which became more expensive to non-U.S. investors.
U.S. crude oil <CLc1> fell $3.40, or 3.26 percent, to $100.98 per barrel, while Brent oil <LCOc1> traded 1.9 percent lower at $113.73 per barrel.
Increased aversion to risk pushed investors into the perceived safety of U.S. government bonds. Benchmark 10-year Treasury notes <US10YT=RR> were up 11/32 in price, with the yield at 3.4285 percent.
