NEW YORK, Nov 11 (Reuters) - The dollar slid and global equity markets fell on Monday after U.S. President Donald Trump's remarks over the weekend dashed investor optimism that Washington and Beijing would soon reach a deal to end their trade war.
Moody's warning on Britain's sovereign debt weighed on shares in London, while escalating violence in Hong Kong led Asian equities to their biggest daily decline since August, boosting demand for the safe-haven yen and Swiss franc.
Trump said on Saturday that the U.S.-Sino trade talks were moving along "very nicely" but more slowly than he would have liked. He also said there had been incorrect reporting about U.S. willingness to lift tariffs.
Last week, U.S. and Chinese officials said they had agreed to roll back tariffs already in place in a "phase one" trade deal.
The 16-month trade war between the world's largest economies has slowed global growth. Data over the weekend showed that China's producer prices fell the most in more than three years in October.
"It's difficult to say who stands to lose more from this deal falling apart, but this last-minute jostling does not inspire confidence," said Craig Erlang, senior market analyst at PANDA Corp.
"We swing from optimism to pessimism on a daily basis and never feel any the wiser," Erlang said.
U.S. stocks ended last week at closing highs, capping a rally that had lifted the S&P 500 more than 7% since early October. MSCI's gauge of equity performance in 47 countries closed last week barely 1% off a record high.
The MSCI all-country world index shed 0.23%, while the FTSEurofirst 300 index of leading regional shares closed down 0.04%.
On Wall Street, the Dow Jones Industrial Average rose 3.88 points, or 0.01%, to 27,685.12. The S&P 500 lost 6.52 points, or 0.21%, to 3,086.56 and the Nasdaq Composite dropped 13.29 points, or 0.16%, to 8,462.02.
The U.S. dollar, which often acts as a safe-haven asset when political and economic uncertainty reins, was lower against the yen and the Swiss franc, other traditional safe havens.
The dollar index fell 0.17%, with the euro up 0.16% to $1.1035. The yen strengthened 0.21% versus the greenback at 109.02 per dollar, while the dollar was 0.42% weaker against the franc, at 0.9930 per dollar.
Gold fell to its lowest in more than three months.
U.S. gold futures settled down 0.4% at $1,457.10 an ounce.
Oil prices slid as trade worries offset industry data showing a drop in U.S. crude inventories at the Cushing, Oklahoma, delivery point.
Brent crude fell 33 cents to settle at $62.18 a barrel. U.S. crude settled down 38 cents at $56.86 a barrel.
A sell-off in southern European bond markets pushed yields higher, with the inconclusive election in Spain adding to uncertainty.
Government bond markets across the single-currency bloc have been hurt in recent weeks by optimism over a U.S.-China trade deal and improving economic data.
