Roundup: U.S. stocks fall amid Fed minutes

U.S. stocks ended sharply lower after a volatile trading session Wednesday, as investors digested the closely-watched minutes from Federal Reserve's July meeting released in the afternoon.

The Dow Jones Industrial Average tumbled 162.61 points, or 0.93 percent, to 17,348.73. The S&P 500 dropped 17.31 points, or 0.83 percent, to 2,079.61. The Nasdaq Composite Index lost 40.30 points, or 0.80 percent, to 5,019.05.

As there is no Fed policy meeting in August, Wall Street kept a close eye on the Fed minutes.

According to the minutes, most U.S. Federal Reserve officials believed conditions for tightening monetary policy were approaching, but failed to give clear signals on the timing of the first interest rate hike in nearly nine years.

The minutes left mixed signals on whether or not the Fed officials decide to raise the interest rate at the next monetary policy meeting in September. Many Fed officials, including its chairwoman Janet Yellen, have said that it's appropriate to raise the benchmark interest rate this year.

Market investors widely see September or even later as the most likely time for a Fed rate increase.

Dampening investor sentiment, oil prices plunged Wednesday as a government report showed that U.S. crude stockpiles last week increased unexpectedly.

The West Texas Intermediate for September delivery moved down 1.82 U.S. dollars to settle at 40.8 dollars a barrel on the New York Mercantile Exchange, while Brent crude for September delivery decreased 1.65 dollars to close at 47.16 dollars a barrel on the London ICE Future Exchange.

Dragging by the diving oil prices, the energy sector, the biggest laggard among the S&P 500's ten sectors, slumped 2.79 percent Wednesday.

On the economic front, the Consumer Price Index (CPI) for All Urban Consumers added 0.1 percent in July on a seasonally adjusted basis, below market consensus of 0.2 percent, the U.S. Labor Department reported Wednesday. Over the last 12 months, the all items index rose 0.2 percent before seasonal adjustment.

The index for all items less food and energy also rose 0.1 percent in July, which grew 1.8 percent for the 12 months ending July.

"The retracement in energy costs will likely drag headline CPI back into negative territory by the end of the quarter, and will filter through to the broader economy throughout the rest of the year," said Jay Morelock, an economist at FTN Financial, in a note.

Overseas, Chinese equities witnessed wild swings Wednesday as persistent worries about economic pressures continued to weigh on market sentiment, with the key Shanghai index fluctuating more than 6 percent.

The benchmark Shanghai Composite Index closed 1.23 percent higher to finish at 3,794.11 points, reversing losses of more than 5 percent in the morning trading session, on speculation of fresh government support, including an expected reserve requirement ratio cut.

The CBOE Volatility Index, often referred to as Wall Street's fear gauge, rose 10.59 percent to end at 15.25 Wednesday.

In other markets, the U.S. dollar dropped against most major currencies amid the Fed minutes on Wednesday.

In late New York trading, the euro rose to 1.1113 dollars from 1.1024 dollars in the previous session, while the dollar bought 123.86 Japanese yen, lower than 124.39 yen of the previous session.

Gold futures on the COMEX division of the New York Mercantile Exchange rose on Wednesday, with the most active gold contract for December delivery up 11 dollars, or 0.98 percent, to settle at 1,127.90 dollars per ounce. Endit
