NewWall Street, global stocks fall on Fed concerns rates may rise in September

World stock indexes fell on Monday as a Federal Reserve official’s comments added to investor concerns the bank may start raising interest rates in September, while oil prices jumped more than 8 per cent, extending their biggest price surge in 25 years.
The S&P 500 registered its biggest monthly percentage drop since May 2012 after being pummeled in the past two weeks on concerns about slowing growth in China.
US crude oil futures jumped 8.8 per cent, helped by a downward revision of US crude production data and OPEC’s readiness to talk with other producers.
Fed Vice Chairman Stanley Fischer said in a speech at the annual Jackson Hole, Wyoming, central bankers’ symposium over the weekend that US inflation was likely to rebound, allowing rates to rise gradually.
Many analysts took Fischer’s comments as a sign the Fed would raise rates in September, instead of December. That shook already jittery stock investors.
"If they move in September, it’s going to cast a lot of doubt about where they will stop," said Stephen Massocca, chief investment officer at Wedbush Equity Management LLC in San Francisco.
