GLOBAL MARKETS-Equities edge higher, dollar gains on last day of choppy quarter

(Adds quote, updates through mid-morning trading)

NEW YORK, Sept 30 (Reuters) - Global equity markets rose and safe-haven assets, including the dollar, gained Wednesday as investors weighed a rising number of COVID-19 cases and a chaotic U.S. presidential debate against better-than-expected U.S. private jobs data on the last day of a turbulent quarter.

Republican President Donald Trump and Democratic rival Joe Biden battled over Trump’s record on the coronavirus pandemic, healthcare and the economy in a bad-tempered first debate Tuesday night marked by personal insults and Trump’s repeated interruptions of Biden.

U.S. stock futures had nudged higher early during the debate but then retreated as Trump cast doubt on whether he would accept the election’s outcome if he lost.

“The only point worth mentioning is that the debate may have increased expectations for a contested election result,” said UBS chief economist Paul Donovan. “Given the importance of international investors to U.S. markets, this may add volatility around the election.”

MSCI’s gauge of stocks across the globe gained 0.62% following modest gains in Europe and mixed trading in Asia.

In midmorning trading on Wall Street, the Dow Jones Industrial Average rose 370.57 points, or 1.35%, to 27,823.23; the S&P 500 gained 33.34 points, or 1.00%, to 3,368.81; and the Nasdaq Composite added 116.09 points, or 1.05%, to 11,201.34.

Better-than-expected gains in ADP’s survey of private payrolls helped push U.S. equities higher.

“The election is not the primary driver of markets right now - the level of economic reopening is,” said David Bahnsen, chief investment officer at the Bahnsen Group.

Globally, markets - most of which are headed for their first monthly retreats since March’s coronavirus-triggered meltdown - either deepened losses or pulled back from highs scaled after data showed China’s economic recovery remains on track.

MSCI’s broadest index of world shares, which tracks nearly 50 countries, is on path for a 4% September loss. Overall, it is on track to close out the quarter with a 7% gain.

Oil is down just over 10% this month, while gold’s 4.1% drop will make it its worst month since late 2016.

The U.S. dollar crept higher and is set for its best monthly gain since July 2019, while Japan’s yen rose 0.2% to 105.50 per dollar, its strongest daily rise in nearly two weeks.

As the Nov. 3 U.S. election draws closer, investors are increasingly expecting a bumpy final lap and are bracing for the possibility that the result will be unclear on Election Day.

Options trade points to a volatile November. Two-month dollar/yen volatility, a gauge of expected moves in the yen, is elevated, and its premium over one-month volatility is near record levels.

In the closing stages of Tuesday night’s debate, Biden said he would accept defeat if he lost at the ballot box and would not claim victory prematurely.

Trump, who has refused to commit to a peaceful transfer of power if he loses the election, repeated unfounded allegations that mail-in voting would lead to fraud.

“I don’t think we were expecting anything else from Trump,” said Chris Weston, head of research at Melbourne brokerage Pepperstone. “He continues to put that contested (result) risk premium back into the market.”

Benchmark 10-year notes last fell 12/32 in price to yield 0.684%, from 0.645% late on Tuesday.

Oil prices were mixed as a rising number of coronavirus cases weighed on demand.

U.S. crude recently rose 0.51% to $39.49 per barrel and Brent was at $40.74, down 0.71% on the day.
