The euro suffered, dropping 1.5 per cent to US$1.3235 by midday trading in New York and falling 1.2 per cent to 102.65 yen.
Italy sold 7 billion euros of 12-month Treasury bills at an average yield of 5.952 per cent, compared with 6.087 per cent at the previous auction of the securities on November 10, according to Bloomberg News. Demand from investors declined to 1.92 times the amount on offer from 1.99.
"It appears that Europe's nightmare has not gone away after all, with investors rethinking Friday's immediately positive response," Andrew Wilkinson, chief economic strategist at Miller Tabak & Co in New York, told Reuters.
Across the pond, Intel added to a general sense of concern about the global economy and corporate profits as the world's largest chip maker slashed its forecast for fourth-quarter revenue because of hard disk drive supply shortages.
After several profit warnings last week including by rival Texas Instruments, Intel was next in line. The company said it now expects revenue to be US$13.7 billion, plus or minus US$300 million, compared with a previous estimate of US$14.7 billion, give or take US$500 million. Analysts predicted US$14.7 billion, the average of estimates compiled by Bloomberg News.
Hendi Susanto, research analyst at Gabeli & Co, told Reuters he was not surprised Intel had cut its outlook, given that Texas Instruments last week reduced its fourth-quarter forecast.
"It's temporary. Most people are expecting the hard disk drive supply will be constrained until at least the end of second quarter 2012," Susanto said.
Meanwhile, the Organisation for Economic Cooperation and Development today said that all major economies were losing momentum.
The OECD's October composite leading indicator (CLI) for its member states dropped to its weakest level since November 2009, falling to 100.1 from 100.4 in September.
There were bright spots. OECD economist Gyorgy Gyomai, who heads the unit in charge of CLIs, said a slowing pace of decline in Canada, China, Russia, Japan and the US was a positive sign and contrasted with ongoing weakness in the euro zone.
"We have really mild indications that for these countries the downward trend may be breaking," he told Reuters.
