Wall Street's main indexes slipped on Tuesday, hit by trade jitters and rising tensions in the Middle East, while investors focused on speeches by Federal Reserve officials for clues on monetary policy.

Fed Chair Jerome Powell is among a host of central bank policymakers scheduled to speak amid rising expectations of an interest rate cut for the first time since the financial crisis.

Traders fully expect a rate cut from the U.S. central bank in July and see a 40% chance of a 50 basis point move, CME Group's FedWatch program showed.

At 11:07 a.m. ET the Dow Jones Industrial Average was down 56.33 points, or 0.21%, at 26,671.21, the S&P 500 was down 12.05 points, or 0.41%, at 2,933.30 and the Nasdaq Composite was down 59.87 points, or 0.75%, at 7,945.83.
