NEW YORK (Reuters) - Stock markets around the world fell hard on Monday on fears that China's willingness to let the yuan slide in response to the latest U.S. tariff threat could further aggravate trade-related tensions between the world's two largest economies.
China on Monday let the yuan <CNY=> tumble beyond the 7-per-dollar level for the first time in more than a decade, in a sign Beijing might be willing to tolerate further currency weakness after U.S. President Donald Trump vowed last week to impose 10% tariffs on the remaining $300 billion of Chinese imports from Sept. 1.
A weaker yuan - and a stronger dollar - pose challenges for U.S. companies that do substantial business in China, as it effectively raises the cost of their goods for Chinese customers.
China also said it would stop buying U.S. agricultural products.
Safe-haven assets, including the Japanese yen, government bonds and gold, rallied as investors cut back on riskier assets.
"I think there's a sense that President Trump might try and escalate in terms of a reaction, if he thinks that this was a deliberate move by the Chinese to try and weaken their currency artificially,” said Brian Daingerfield, head of G10 FX strategy for the Americas at NatWest Markets in Connecticut.
Against the Japanese yen, the U.S. dollar fell 0.43% to its lowest level since a January flash crash. <JPY=>
Trade-sensitive emerging market currencies took a beating. The emerging market currency index <.MIEM00000CUS> fell 1.24% to set a 2019 low, on pace for its worst one-day drop since June 2016.
MSCI's All Country World Index <.MIWD00000PUS>, which tracks shares in 47 countries, extended last week's slide and was down 2.53% to a two-month low.
On Wall Street, the main indexes logged steep declines, led by technology companies.
"The currency move is part of the trade war," said Andre Bakhos, managing director at New Vines Capital LLC in Bernardsville, New Jersey. "It is a bold statement to the U.S. that says 'If you want to play, we could play a different way as well.' It takes any optimism out of the market that there will be a quick resolution to trade."
The Dow Jones Industrial Average <.DJI> fell 767.27 points, or 2.9%, to finish at 25,717.74, the S&P 500 <.SPX> lost 87.31 points, or 2.98%, to close at 2,844.74 and the Nasdaq Composite <.IXIC> dropped 278.03 points, or 3.47%, to end at 7,726.04.
The pan-European STOXX 600 index <.STOXX> closed down 2.31%. Factoring in Friday's losses, the index marked its largest two-day decline in over three years. [.EU]
Worries about a slowdown in global growth due to an extended trade conflict also hurt oil prices.
"The escalation in the U.S.-China trade is another negative for the oil demand outlook, as the fallout from the spat continues to greatly impact the Asian economic region, which is key to the oil demand outlook," said John Kilduff, partner at Again Capital Management.
Brent crude <LCOc1> fell $2.08, or 3.36%, to settle at $59.81 a barrel, while U.S. West Texas Intermediate (WTI) crude <CLc1> futures fell 97 cents, or 1.74%, to settle at $54.69 a barrel.
Gold rose to a more than six-year high. Spot gold <XAU=> was up 1.52% at $1,462.32 per ounce.
ADVERTISEMENTU.S. Treasury yields tumbled, with 10-year yields hitting their lowest level since November 2016 on the safety bid.
In late U.S. trading, the yield on benchmark 10-year Treasury notes <US10YT=RR> was down 12.7 basis points at 1.7278%.
