NEW YORK, Sept 23 (Reuters) - The U.S. government's proposed $700 billion bailout of Wall Street dominated markets on Tuesday, with the dollar rising on optimism the plan would aid the economy but global stocks falling on uncertainty over its fate.
U.S. and euro-zone government bond prices rose and inter-bank lending rates stayed far above central bank target levels as investors worried about the viability of a plan that lawmakers must approve and that will be paid for by taxpayers.
Oil prices fell more than $3 a barrel, reversing direction after Monday's dramatic rally, as dealers focused on slowing global energy demand and doubts over the U.S. bailout plan. Other commodities also tumbled, with copper down almost 4 percent, with profit-taking on the firmer dollar adding pressure.
As investors focused on congressional testimony by U.S. Treasury Secretary Henry Paulson and Federal Reserve Chairman Ben Bernanke, tightness in credit market was very much alive. A closely watched gauge showed banks are still reluctant to make loans to each other.
The spread between the borrowing cost on three-month dollar funds in the inter-bank market and the expected three-month rate on benchmark U.S. federal funds widened, signaling banks' unwillingness to part with their cash beyond a week.
"I just don't think the American public is sold. I think they are skeptical of the need and they are fearful of the cost," David Dietze, chief investment officer at Point View Financial Services in Summit, New Jersey.
"The skepticism is that this is going to help the Wall Street financiers and do nothing for the little guy other than saddle them with a big tax bill," Dietze said.
U.S. stocks fell, as lower commodity prices dragged down natural resources companies, reversing earlier gains on hopes the proposed bailout would help loosen up credit markets, while boosting business and consumer spending.
Investors were cautious and trading was choppy a day after Wall Street's slide wiped out gains from Friday that were driven by initial enthusiasm over the rescue plan.

Miners also fell sharply, tracking metal prices. Anglo American <AAL.L> was the most heavily weighted loser on the index, falling 8.2 percent, while Rio Tinto <RIO.L> lost 5.1 percent.
U.S. elections in November make the bailout a sensitive subject, and politicians will do their utmost to make populist changes, said Emiel van den Heiligenberg, head of asset allocation at Fortis Investments in London.
"We would expect the plan to be accepted, perhaps in a slightly amended form, but stay cautious on markets because of the recession and the impact on earnings," he said.
