NEW YORK, June 1 (Reuters) - The euro fell to a four-year low on Tuesday on worries the euro zone's debt crisis is spreading to its banking system, and the price of U.S. Treasuries and gold rose as investors sought safe havens.
U.S. stocks bounced between negative and positive territory, hurt by a warning from the European Central Bank on the region's public finances but buttressed by better-than-expected U.S. construction and manufacturing data.
The European Central Bank warned on Monday that euro zone banks could face another 195 billion euros $239 billion in a "second wave" of potential loan losses over the next 19 months due to the the financial crisis. For more, see [

"The ECB warning on Monday set the stage for euro selling," said Matthew Strauss, senior currency strategist at RBC Capital Markets in Toronto. "Markets remain jittery and overall risk sentiment is bearish," he said.
After May marked the most volatile month of trading since the aftermath of Lehman Brothers' collapse in late 2008, investors focused on concerns that growth would slow in a euro zone struggling to rein in debt, in turn reducing demand for exports from economies like China, slowing production there.
Concerns over another crisis in the banking sector were compounded by data signaling slowing manufacturing growth in Europe and China. In the United States, a revival in the factory sector due to overseas demand and inventory restocking has helped to lead an economic rebound over the past three quarters.
"Treasuries and the dollar remain the safe haven because the euro zone problem will not go away any time soon," said Frank Cholly Sr., a senior market strategist at Lind Waldock in Chicago.

The dollar rose to its highest in 15 months against a basket of major currencies.
A survey showed manufacturing activity in the euro zone expanded in May at a considerably more sluggish pace than in April, while separate data showed the pace of China's factory output eased last month.
China's PMI, an indicator of factory activity, compiled by the China Federation of Logistics and Purchasing, fell to 53.9 in May from 55.7 in April, close to analysts forecasts of 54.0.
However, it stood above the threshold of 50 that separates expansion from contraction for the 15th consecutive month.
"The figures point to slower economic growth toward the end of this year," said Eugen Weinberg, commodities analyst at Commerzbank in Frankfurt. The fear is that Chinese officials will tighten monetary policy and this will also dampen growth."
