NEW YORK, June 25 (Reuters) - Wall Street opened lower and global stock markets sank on Monday as a trade dispute between the United States and other leading economies worsened, while U.S. Treasuries and other safer investments gained.

A U.S. government official on Sunday said the Treasury Department was drafting curbs that would block firms with at least 25 percent Chinese ownership from buying U.S. companies with "industrially significant technology."

Separately, a report by the Wall Street Journal said the U.S. Commerce Department and National Security Council were proposing "enhanced" export controls to keep such technologies from being shipped to China.

The news sent equities sharply lower.

“Trade wars typically have a negative impact on the markets. Markets don’t like uncertainty,” said Justin Lederer, an interest rate strategist at Cantor Fitzgerald in New York.

In mid-morning trading, the Dow Jones Industrial Average fell 279.69 points, or 1.14 percent, to 24,301.2, the S&P 500 lost 31.82 points, or 1.16 percent, to 2,723.06 and the Nasdaq Composite dropped 136.59 points, or 1.78 percent, to 7,556.22.

Technology stocks bore the brunt of the news, with the S&P technology index falling 1.5 percent, the most among the major S&P 11 sectors.

The report hit Asian stocks overnight and in London the pan-European FTSEurofirst 300 index lost 1.88 percent and MSCI (Frankfurt: 3HM.F - news) 's gauge of stocks across the globe shed 1.26 percent.

Policymakers in China moved quickly to temper any potential economic drag from its dispute with the United States. Its central bank said on Sunday it would cut the amount of cash some banks must hold as reserves by 50 basis points.

The European autos sector, was hit by trade tensions between Washington and Europe, falling 2.7 percent and set for its seventh straight day of losses after U.S. President Donald Trump said on Friday he aimed to hike tariffs on EU car imports by 20 percent.

The index of global auto manufacturers fell 1.34 percent.

A senior European Commission official said on Saturday (Shenzhen: 002291.SZ - news) that the European Union would respond to any U.S. move to raise tariffs on cars made in the bloc.

Harley-Davidson Inc said on Monday it would move production of motorcycles shipped to the European Union from the United States to its international facilities and forecast the trading bloc's retaliatory tariffs would cost the company $90 million to $100 million a year.

The growing disputes have led investors to take refuge on safer ground. The U.S. Treasury yield curve between 2-year and 10-year notes flattened to 33 basis points, the lowest level since 2007.

Meanwhile, Brent crude oil fell as investors prepared for an extra 1 million barrels per day in output to hit the markets after OPEC and its partners agreed to raise production.

Brent was last at $74.36, down 1.58 percent on the day.

In the currency market, the dollar index fell 0.12 percent, with the euro up 0.26 percent to $1.1685.

The Japanese yen strengthened 0.25 percent versus the greenback at 109.69 per dollar, while Sterling was last trading at $1.3266, down 0.02 percent on the day.

The Turkish lira rose on expectations of a stable government after Tayyip Erdogan and his ruling AK Party claimed victory in presidential and parliamentary polls.

Bitcoin steadied after hitting seven-month lows over the weekend as the security of cryptocurrency exchange operators came under more scrutiny.
