GLOBAL MARKETS-Stocks, oil fall as US-China tariff war escalates

Updates with closing US market levels

By Caroline Valetkevitch

NEW YORK, April 8 (Reuters) - Major stock indexes fell on Tuesday as the trade war between the United States and China intensified, while oil prices and the U.S. dollar also eased.

The United States said 104% duties on imports from China will take effect shortly after midnight. The news drove up concerns about slowing growth and higher inflation that have pummelled stocks since last week.

S&P 500 companies have lost $5.8 trillion in stock market value since U.S. President Donald Trump's tariff announcement late last Wednesday, the deepest four-day loss since the benchmark was created in the 1950s, according to LSEG data.

The U.S. Treasury yield curve reached its steepest level since February 2022 on Tuesday as longer-dated yields jumped on supply concerns.

On Wall Street, the S&P 500 closed below 5,000 for the first time in almost a year. Stocks had been sharply higher early in the day amid investor optimism that Washington might be willing to negotiate on some of its aggressive tariffs.

"People wanted to be optimistic and eventually realized they didn't have a good reason," said Melissa Brown, managing director, investment decision research, at SimCorp.

The Cboe Volatility index .VIX climbed for a fourth straight session and had its highest closing level since April 1, 2020.

The Trump administration also is negotiating trade agreements with countries, including Japan, and Treasury Secretary Scott Bessent said the discussions are the result of multiple calls from other countries.

The Dow Jones Industrial Average .DJI fell 320.01 points, or 0.84%, to 37,645.59, the S&P 500 .SPX fell 79.48 points, or 1.57%, to 4,982.77 and the Nasdaq Composite .IXIC fell 335.35 points, or 2.15%, to 15,267.91.

MSCI's gauge of stocks across the globe .MIWD00000PUS fell 2.52 points, or 0.34%, to 742.96. The pan-European STOXX 600 .STOXX index rose 2.72%.

Investors are looking ahead to the start of U.S. quarterly earnings reports this week.

Adam Sarhan, chief executive of 50 Park Investments in New York, said upbeat results could potentially be a catalyst to support stocks.

JPMorgan Chase JPM.N, Citigroup C.N and Wells Fargo WFC.N will kick off results on Friday. JPMorgan's CEO Jamie Dimon has warned that trade wars could have lasting negative consequences, including inflation and recession.

In Treasuries, the curve between two- and 10-year note yields US2US10=TWEB steepened sharply to 57 basis points, as the two maturities moved in opposite directions on a volatile day of trading.

The benchmark 10-year yield rose to an 11-day high on worries about weak demand for longer-dated U.S. government debt before a sale of the notes on Wednesday.

The 10-year note yield US10YT=RR was last up 12.6 basis points on the day at 4.283%. It fell to 3.86% on Friday, the lowest since October 4.

The interest-rate sensitive two-year yield US2YT=RR reversed an earlier increase and fell 2.3 basis points to 3.715%. It had reached 3.435% on Monday, the lowest since September 2022.

The euro gained following reports that German political parties had agreed to form a coalition, while the U.S. dollar weakened against major currencies and China's offshore yuan hit a record low. European equity index futures also rose after the reports.

Germany's conservatives under chancellor-in-waiting Friedrich Merz on Tuesday reached a deal with the centre-left Social Democrats $(SPD.AU)$ to form a government, NTV reported. But two people with knowledge of the matter denied to Reuters that a deal has been reached.

The dollar, which has taken a beating from the tariff turmoil, remained weak against other major currencies.

The dollar index =USD, which measures the greenback against a basket of currencies including the yen and the euro, fell 0.48% to 102.92.

Oil prices ended lower amid the recession worries as the U.S.-China trade war escalated.

Brent futures LCOc1 fell $1.39, or 2.16%, to settle at $62.82 a barrel. U.S. West Texas Intermediate crude futures CLc1 settled down $1.12, or 1.85%, at $59.58.
