Uncertainty over whether Washington can avert a "fiscal cliff", $600 billion worth of tax increases and spending cuts that will be automatically triggered in early 2013, are keeping investors nervous.
The White House dismissed a proposal from congressional Republicans on Monday that included tax reforms and spending cuts, saying it did not meet President Barack Obama's pledge to raise taxes on the wealthiest Americans.
The Republicans proposed overhauling the U. S. tax code to raise $800 billion in new revenue over ten years. Obama's opening bid, outlined last Friday, seeks $1.6 trillion in new revenue by allowing the expiry of tax cuts enacted under President George W. Bush for the top two tax brackets.
