NEW YORK, Jan 30 (Reuters) - Signs of deepening economic weakness around the world on Friday dragged stocks lower, with the Dow close to its worst decline in January since 1960, and investors fled to the safety of gold and government debt.
Gold futures jumped nearly 2 percent on flight-to-quality buying and record investment demand, while the price of longer-dated U.S. and euro zone government bonds rose, bolstered by demand for safe-havens in financial markets.
A plunge in euro zone inflation, a record fall in Japanese industrial production and the fastest shrinking of the U.S. economy in nearly 27 years heightened fears that the global downturn could be worst than many investors had feared.
World stocks, as measured by MSCI's all-country index <.MIWD00000PUS>, fell 1.6 percent on Friday and was poised to close the month down more 8 percent.
European shares rose and fell throughout the session but a close reading of a report on U.S. gross domestic product put a damper on investment sentiment as it showed a large rise in unsold goods, suggesting further corporate cutbacks ahead.
U.S. GDP fell at a 3.8 percent annual rate in the fourth quarter, but business equipment and software spending fell 27.8 percent and exports slipped 19.7 percent.
"This is one where the headline is clearly better than people were expecting," said Nigel Gault, chief U.S. economist at Global Insight in Lexington, Massachusetts. "But underneath, those details do not look healthy and it's telling us firms were not cutting production as fast as their sales were falling.
"And that's a bad sign for what's going to happen in the first quarter because it says they got to work off these excess inventories," Gault said.
Highlighting the corporate slowdown, Procter & Gamble Co <PG.N>, the world's largest consumer products maker, reported profit that missed expectations, becoming the latest company to cut its full-year earnings forecast on weaker demand.

Oil shares also fell, with BP <BP.L> down 0.9 percent and Royal Dutch Shell <RDSa.L> off 3.4 percent.
The euro weakened against the dollar as the data further underlined the region's vulnerability, but shorter-dated euro zone government bonds rallied on speculation the European Central Bank will cut interest rates earlier than expected.
The euro <EUR=> was down 1.12 percent at $1.2813.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.53 percent at 85.939. Against the yen, the dollar <JPY=> was down 0.09 percent at 89.85.
Inflation in the euro zone plunged in January to its lowest in almost 10 years and unemployment rose more than expected, boosting pressure on the ECB to cut rates further.
"The inflation number was definitely a shock, a much bigger-than-expected drop, and just shows how strong disinflationary pressures are in Europe," said Matthew Sharratt, an economist at Bank of America.
In Japan, industrial production fell a record 9.6 percent in December while core annual inflation almost evaporated, reinforcing expectations of a record economic contraction as the global financial crisis worsens.
