US stocks closed Tuesday in negative territory one day before key consumer inflation figures are released. 

The Dow was down 192 points, or 0.62% to end at 30,981. The S&P 500 fell 35 points, or 0.92%, to 3,818.

The Nasdaq was off 107 points, or 0.95%, to finish at 11,264.

Investors await inflation figures that will be released before markets open Wednesday.

Analysts expect it to show an increase of 8.8% in June, up from an annual gain of 8.6% in May.

If the figure is higher, the US Federal Reserve will be forced to make more aggressive moves in its monetary policy that could lower liquidity in markets.

The 10-year US Treasury yield fell 1% to 2.961%.

The dollar index rose to 108.17 for a 0.14% gain after soaring to 108.56 during the session to a 20-year high.
