TOKYO (Reuters) - Global stocks barely budged on Friday as investors tightened positions with less than two weeks to go before the U.S. presidential election and awaited a breakthrough in stimulus talks in Washington. The final debate between U.S. President Donald Trump and his Democrat challenger Joe Biden on Thursday presented few surprises for election watchers but slightly reinforced investor caution heading into the Nov. 3 poll. U.S. S&P 500 futures ESc1 had dipped slightly after the debate but were mostly flat by midday trade. The underlying index had gained about 0.5% in the previous day on hopes that the U.S. Congress and the White House could soon strike a deal on another round of COVID-19 stimulus. Shares in Asia hardly budged, with MSCI"s broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS flat while Japan"s Nikkei .N225 ticked up 0.2%. The CSI300 index of mainland China .CSI300 also edged up 0.2%. At Thursday’s debate, Biden renewed his criticism of Trump’s handling of the coronavirus pandemic as Trump levelled unfounded corruption accusations at Biden and his family. “I don’t think there’s anything new in it, I think that’s why the market is not moving much. The focus is still on the timing of the fiscal stimulus and how big it is,” said Moh Siong Sim, FX analyst at Bank of Singapore. On Thursday, U.S. House of Representatives Speaker Nancy Pelosi reported progress in talks with the Trump administration for another round of financial aid, saying legislation could be hammered out “pretty soon”. While the news helped to lift U.S. share prices, the U.S. S&P500 .SPX is still down 0.9% so far this week amid uncertainties over stimulus and the election. A widening lead in polls by Biden is prompting many investors to bet on a Biden presidency and also a “blue sweep”, where Democrats win the both chambers of Congress. “A blue wave may lead to concerns about the impact on the tech sector, while a Biden win and a split Congress may imply another four years of limited policy changes and politicking,” said Mary Nicola, senior economist at Pinebridge Investments in Singapore. Reflecting concerns Democrats could take a harder stance on big tech firms, the Nasdaq index .IXIC, which had led the market"s rally, has underperformed lately, having lost 1.4% so far this week. Expectations of bigger government stimulus have also boosted U.S. borrowing costs. The 10-year U.S. Treasuries yield US10YT=RR rose to 4 1/2-month high of 0.870% on Thursday and last stood at 0.853%. U.S. economic data published on Thursday surprised to the upside, as jobless claims fell more than expected and existing home sales exceeded estimates to more than a 14-year high. In the currency market, the dollar bounced back from Wednesday’s seven-week low but stayed under pressure as investors began to wager on a Biden presidency and big U.S. stimulus. The euro traded at $1.1803 EUR=, down 0.2% and off Wednesday"s high of $1.1805 but still up 0.7% on the week. The yen changed hands at 104.77 yen per dollar JPY=, stepping back a tad after its biggest gain in nearly two months on Wednesday. The Chinese yuan stood at 6.6729 per dollar in offshore trade CNH=, off 27-month high of 6.6278 touched on Wednesday. Oil prices were supported by hopes on U.S. stimulus and the prospect of extended output cuts. Brent futures LCOc1 ticked up 0.3% to $42.59 per barrel while U.S. crude futures CLc1 rose 0.25% to $40.74 per barrel.
