US stock indices save the positive dynamics after the Fed head Jerome Powell on Tuesday gave a positive assessment of the current state of the American economy.

According to Powell, the state of the US economy, the growth in the number of jobs and the acceleration of inflation "make the best solution is the gradual increase in rates".

In conditions when unemployment is 4%, and annual inflation has recently reached the target level of the central bank of 2%, the Fed management does not want to allow the economy to overheat.

On Wednesday, Jerome Powell will continue his speech, which will begin at 14:00 (GMT). It is likely that Powell will reaffirm the Fed's intention to further gradually increase the interest rate.

As US Treasury Secretary Stephen Mnuchin said last week, the US economy will not suffer as a result of the introduction of import duties.
