NEW YORK/LONDON, July 23 (Reuters) - Anxiety about the looming results of European bank stress tests pushed the euro down against the dollar and weighed on global stocks on Friday.
Oil prices fell and Treasuries trimmed some losses as investors favored safe-haven assets, on fears that the stress tests results, even if positive, may not show the true health of financial institutions.
The tests -- whose results were due to released at 12 p.m. EDT (1600 GMT) -- were designed to provide a clear picture of the impact of the Europe's sovereign debt crisis on its financial institutions. But on Friday regulators said they were applied only to the bank's trading books, not their banking books. For details, see [
]."This is a surprise in the sense that the scope of the stress test is limited to a certain portion of the banks' risk," said Christian Cooper, senior rates trader at Jefferies & Co. in New York. "It's going to be a little bit less insightful or meaningful than the already watered-down expectations."
Nonetheless, some saw the potential for sharp moves in financial markets.
"There is definitely the potential for a huge swing in either direction, followed by an equally enormous reversal as all of the information is digested." said Dan Cook, a senior market analyst at IG Markets, in Chicago/
Both U.S. and European stocks managed to edge higher ahead of the test results. On Wall Street, solid corporate results, including those of Microsoft <MSFT.O> and Ford <F.N>, helped push up the S&P 500 and Dow industrials.
In Europe, mining shares were among gainers as copper hit a two-month high. But financial stocks were mostly lower.
Also bringing some optimism to the market was data showing German business sentiment jumped in July to its highest level in three years. The report from the Munich-based Ifo think-tank helped ease concerns that the global economy could slip back into recession.
"We expected an increase but we didn't expect this. The German economy is running really strong at the moment," said Ralph Solveen at Commerzbank.
"Companies are not letting themselves be distracted by all the negative discussions going on, such as the bank stress tests, the debt crisis or the threat of a double-dip recession in the United States."
