Weak U.S. data reaffirmed investor worries Friday, fueling a sell-off in global equities and pressuring U.S. Treasury yields to multi-month lows.

Richly valued technology firms took much of the pain, and an index of European bank stocks headed for its largest weekly decline in 17 months on soft earnings.

The VIX stock market volatility measure, dubbed Wall Street's fear gauge, surged.

UNEXPECTED WEAKNESS

Investors turned to safe havens, including government debt and gold, as Friday's U.S. jobs report flagged unexpected economic weakness.

Markets were already rattled by downbeat earnings updates from Amazon and Intel and Thursday's softer-than-expected U.S. U.S. factory activity survey and the monthly U.S. non-farm payrolls report, which showed job growth slumped to 114,000 new hires in July from 179,000 in June.

The weak data raised expectations of multiple rate cuts by the Federal Reserve this year, which just this week opted to keep rates unchanged.

"The jobs data are signaling substantial further progress that the Federal Reserve made a policy error by not reducing the Fed Funds rate this week," said Jamie Cox, managing partner for Harris Financial Group in Richmond, Virginia.

"It’s very possible the Fed alters its inter-meeting communications on the balance of risks to remove all doubt all a September rate cut. "

With thin summer trading likely exaggerating moves, a slump that began in Asia with a 5.8% drop for Japan's Nikkei, its biggest daily fall since March 2020 during the COVID-19 crisis, rippled through Europe and headed for Wall Street.

MSCI's global stock gauge MSCI's gauge of stocks across the globe fell 2.26% to 785.26.

The Dow Jones Industrial Average fell 569.93 points, or 1.41%, to 39,778.04, the S&P 500 lost 119.44 points, or 2.19%, to 5,327.24 and the Nasdaq Composite lost 560.79 points, or 3.26%, to 16,633.36.

The STOXX 600 index fell 2.42%, while Europe's broad FTSEurofirst 300 index fell 49.58 points, or 2.44%

Emerging market stocks fell 23.92 points, or 2.20%, to 1,063.88. MSCI's broadest index of Asia-Pacific shares outside Japan closed 2.27% lower 2.27%, at 554.93.

Japan's Nikkei fell 2,216.63 points, or 5.81%, to 35,909.70.

The Fed has kept benchmark borrowing costs at a 23-year high of 5.25%-5.50% for a year, and some analysts believe the world's most influential central bank may have kept monetary policy tight for too long, risking a recession.

Money markets on Friday rushed to price a 70% chance of the Fed, which was already widely expected to cut rates from September, implementing a jumbo 50 basis points cut next month to insure against a downturn.

The "employment report flashes a warning signal that this economy does have the ability to turn rather quickly," said Charlie Ripley, Senior Investment Strategist for Allianz Investment Management in Minneapolis.

"Ultimately, today’s employment data should embolden the committee to cut policy by more than 25 basis points at the next meeting."

RUSH FROM TECH

Shares in U.S. chipmaker Intel tumbled to a more than 11-year low after the group suspended its dividend and announced hefty job cuts alongside underwhelming earnings forecasts.

Artificial intelligence chipmaker Nvidia, one of the biggest contributors to the tech rally, dropped 4.2%

Nvidia, up more than 700% since January 2023, has left many asset managers with an outsized exposure to the fortunes of this single stock.

Safe-haven buying went full throttle, with government debt, gold and currencies traditionally all rallying. They are assets viewed as likely to hold value during market chaos.

The yield on benchmark U.S. 10-year notes fell 15 basis points to 3.828%, from 3.978%.

The 2-year note yield, which typically moves in step with interest rate expectations, fell 24.6 basis points to 3.9187%, from 4.165%.

In foreign exchange markets, the yen added over 1%, extending a rapid bounceback as the Bank of Japan raising interest rates to levels unseen in 15 years.

In commodities, spot gold added 0.92% to $2,467.89 an ounce. U.S. gold futures gained 1.4% to $2,469.10 an ounce.

Oil prices, however, took a hit on the growth worries. U.S. crude lost 3.3% to $73.79 a barrel and Brent fell to $77.19 per barrel, down 2.93% on the day.

Both benchmarks have fallen around 10% over the past four weeks in the longest run of weekly losses this year.
