NEW YORK, May 29 (Reuters) - Fears that an escalating trade war between the United States and China will slash global economic growth pulled world stock markets down to near two-and-a-half-month lows on Wednesday and continued to feed a rally in safe-haven government bonds.
German bond yields fell deeper into negative territory and inched toward record lows of minus 0.2%. Ten-year U.S. Treasury note yields dropped to 20-month lows, having fallen almost 30 basis points this month.
Chinese newspapers warned on Wednesday that Beijing could use rare earths to strike back at the United States after U.S. President Donald Trump remarked he was "not yet ready" to make a deal with China over trade.
China was the source of 80 percent of the rare earths imported by the United States between 2014 and 2017. prospect of a prolonged standoff between the world's two biggest economies and the likelihood of Europe and Japan getting dragged in have raised investor concerns about global growth.
With economic data showing that U.S. manufacturing growth dropped to 10-year lows, another round of tariffs would sharply raise the risk of a U.S. recession, said Justin Onuekwusi, a fund manager at Legal & General Investment Management.
“The market is simply calculating what the impact will be of the next set of tariffs as it doesn't look like the rhetoric is calming down,” Onuekwusi said.
“Then we have a weaker growth outlook ... so we have the negative shock of trade added to lower growth and the cushion of protection isn't as good as it was eight to nine months ago.”
Those concerns dragged MSCI's global equity index .MIWD00000PUS down 0.9% to a 2 1/2-month low following losses across Asia.
On Wall Street, the Dow Jones Industrial Average .DJI fell 221.36 points, or 0.87%, to 25,126.41, the S&P 500 .SPX lost 19.37 points, or 0.69%, to 2,783.02 and the Nasdaq Composite .IXIC dropped 60.04 points, or 0.79%, to 7,547.31.
The pan-European STOXX 600 index .STOXX lost 1.43%.
Concerns over the fate of Britain's exit from the European Union also helped drive U.S. 10-year yields about 10 basis points below the three-month rates, an inversion typically seen as a leading indicator of a recession. The inversion is the deepest in almost 12 years.
“What I see as more consistent is that typically when the yield curve inverts you get central bank easings. So the question about recession would be: would the U.S. Fed ease enough to avoid a recession?” said Chris Rands, Sydney-based fixed income portfolio manager at Nikko Asset Management.
Data this week showed a gauge of U.S. manufacturing activity unexpectedly fell in May from the previous month. That follows earlier disappointing readings on U.S. manufacturing and industrial output, Rands said.
“The fact that you have got a bit more noise around the trade war now at the same time as manufacturing is rolling over — it's getting people to think that things are a little bit worse than they had expected,” he said.
Currency activity was muted, with the dollar index .DXY , tracking the U.S. unit against six major currencies, up at 97.905. The dollar is on track for a fourth month of gains, benefiting from flows away from markets such as Asia that are considered at greater risk from trade wars.
The euro was unchanged at $1.1159 after falling two straight days. The British pound held at $1.2656.
Commodity markets were also dominated by fears of a global economic downturn. Brent crude was off more than 1% at $69.15 per barrel. Gold benefited from the safe-haven bid, rising half a percent to $1.285 an ounce.
