LONDON, Sept 29 (Reuters) - European shares slipped on Tuesday as investors awaited a pivotal U.S. presidential debate and watched for progress of a fiscal stimulus package in Washington.
The broad Euro STOXX 600 .STOXX fell 0.4%, eroding hefty gains from a day earlier, with indexes in Frankfurt .GDAXI , Paris .FCHI and London .FTSE losing between 0.2% and 0.5%.
Among the sectors in negative territory were growth-sensitive banks .SX7P , automakers .SXAP and travel & leisure .SXTP , all down 0.8%-1.5%.
U.S shares were set to open a touch lower, with futures for the S&P 500 EScv1 and Nasdaq NQc1 giving up earlier gains to slip into negative territory. Hard-hit sectors like hotels, banks and airlines had made strong gains on Monday.
Investors are weighing the potential impact on the U.S. economy of either the re-election of President Donald Trump or a victory for Democratic presidential nominee Joe Biden.
Many see a Biden victory increasing the chances of further fiscal stimulus to counter the economic damage from the COVID-19 pandemic, judging such a scenario a boon for stocks.
"What seems clear is that were you to see a blue wave, a Democratic sweep, you'd see substantial fiscal stimulus," said Mike Bell, global market strategist at J.P. Morgan Asset Management. "The risk, I have always thought, to this recovery is premature fiscal tightening."
With time running out to change minds or influence undecided voters, the stakes are high as the two White House candidates take the stage five weeks before the Nov. 3 election. campaign has seized on a fresh line of attack on the eve of the debate with Trump - set for after the U.S. market close - accusing the Republican incumbent of gaming the system to avoid paying his fair share of taxes. debate will be critical, since it represents one of the last set-piece opportunities for either candidate to change the contours of the race," Deutsche Bank (DE:DBKGn) analysts wrote in a note.
The MSCI world equity index .MIWD00000PUS , which tracks shares in nearly 50 countries, was flat.
As the global death toll from COVID-19 rose past one million, according to a Reuters tally, investors have remained focused on prospects for a stimulus package to help the U.S. economy recover from the damage wrought by the virus. House of Representatives Speaker Nancy Pelosi said on Monday that Democratic lawmakers had unveiled a new, $2.2 trillion coronavirus relief bill. Pelosi in recent days has said she thinks a deal can be reached with the White House on a new coronavirus relief package and that talks were continuing. MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS was flat, shedding earlier gains.
Stimulus packages were also in focus in bond markets, where Germany's 10-year bond yield DE10YT=RR fell to its lowest in seven weeks before first-estimate inflation readings for September. CONSUMERS?
Also in focus was economic data due later in the day that is set to shed light on the U.S. economy's progress, with consumer confidence and home price data on the agenda.
