Investors fled from the US stock market and the dollar on Wednesday after employment and manufacturing data signaled that US economic growth may be slowing more quickly than expected.

Yields on benchmark 10-year US Treasury debt, the favourite asset of investors looking for a safe place to store cash when times get tough, fell below 3.0 percent for the first time since December.

Gold, another safe haven, rose nearly 1.0 percent, while crude oil prices fell by up to 1.0 percent.

"The sugar high that has buoyed the US economy over the past 6 months is wearing out, and there is little in economic growth or foundation to show for it. The US dollar has no choice but to weaken given exports are the only bright spot in the United States," said Douglas Borthwick, a managing director with Faros Trading in Stamford, Connecticut.
   
Growth in the US manufacturing sector slowed sharply in May with the Institute for Supply Management's (ISM) index of national factory activity falling to 53.5 in May, its lowest level since September 2009.

That followed surprising private employment data from payrolls processor ADP that showed poorer job growth in May than expected, leading many Wall Street banks to slash forecasts for Friday's May employment data.

ADP's survey showed private employers in the United States added a scant 38,000 jobs in May, nearly four times below that expected by the market.

The job additions were the lowest published by the ADP since September 2010. Total non-farm payroll numbers for May are not due from the US Labor Department until Friday, but analysts do expect the official data to be much better.   

"It fits very neatly in with the puzzle we are putting together that speaks to another soft patch and really, a genuinely failed stimulus approach to growing the economy," said Peter Kenny, managing director at Knight Capital in Jersey City, New Jersey.

"And it's not just about jobs. It's about manufacturing, it's about real estate, it's about consumer confidence. This is one data point in a very broad picture, and it's not encouraging."  - Reuters
