LONDON — United States markets opened lower on Monday, led by another decline in energy shares as the price of oil slips.

After two weeks of heavy turbulence, the market is on the verge of closing out its worst month in more than three years.

KEEPING SCORE In early trading, the Dow Jones industrial average fell 0.94 percent and the Standard & Poor’s 500-stock index was down 0.76 percent. The Nasdaq composite index dropped 0.46 percent.

ENERGY Noble Energy sank 6 percent, the most in the S.&P. 500 index. Benchmark United States crude declined 64 cents to $44.58 a barrel on the New York Mercantile Exchange. After a two-month decline, crude gained last week but appears ready to lose more ground.

EUROPEAN MARKETS In Germany, the DAX fell 0.9 percent and in France, the CAC 40 also lost 0.9 percent. Markets in London were closed because of a holiday.

FED TALK Stanley Fisher, the Fed’s vice chairman and a close adviser to the Fed chairwoman, Janet L. Yellen, said on Saturday at an annual gathering in Jackson Hole, Wyo., of central bankers that there was a “pretty strong case” for raising rates in September. That ran counter to recent market sentiment that China’s economic slowdown and global market volatility might prompt the Fed to wait.

Mr. Fisher emphasized that he was not saying what action the Fed might take at its September meeting, but analysts interpreted his comments as meaning that the economy was moving close to satisfying the Fed’s conditions for a rate increase.

It would be the Fed’s first reverse from its policy in place since the 2008 crisis of ultra-low rates that have pushed up stock prices.

ANALYST’S TAKE “The Fed is still at the drawing board with regards to the specifics of the timing of a rate hike this year,” said analysts from Mizuho Bank in a report. “But to be sure conviction for a hike this year was not watered down. What’s more, a rate hike sooner rather than later is preferred on forward-looking inflation.”

SLUGGISH DATA In Japan, industrial production fell unexpectedly by 0.6 percent in July from the previous month, defying expectations of a small increase. “The drop in industrial production in July suggests that economic activity will recover only slowly this quarter,” said the analyst Marcel Thieliant of Capital Economics in a report.

In Europe, official figures showed the annual inflation rate remained at a weak 0.2 percent in the 19-country eurozone. The figure was broadly expected but underlines the challenges facing the European Central Bank in bringing inflation back toward its 2 percent target.

ASIAN MARKETS The Nikkei 225 declined 1.3 percent in Japan, while in Hong Kong, the Hang Seng gained 0.3 percent. The Shanghai Composite Index was down by as much as 2.6 percent during the day, but recovered to close down 0.3 percent in China. The Kospi was up 0.2 percent in South Korea. In Australia, the S.&P./ASX 200 lost 1.1 percent, while the Sensex in India was off 0.3 percent. Markets in Taiwan, Bangkok and Jakarta rose while Singapore and New Zealand fell.

CURRENCIES AND BONDS The dollar declined to 121.36 yen from 121.38 yen on Friday. The euro rose to $1.1204 from $1.1180.

Bond prices rose. The yield on the 10-year Treasury note fell to 2.14 percent.
