Investors are gearing up for another assessment of the global economy, as the Federal Reserve is set to release the minutes of its March meeting later on Wednesday. Stewart Warther, a U.S. equity and derivatives strategist at BNP Paribas said the markets were rewarded with dovish comments from Fed Chair Janet Yellen's speech last week, but thinks Wednesday's minutes will be slightly less accommodative. 'I think the key here will be the assessment of the balance of risks and seeing where all of the committee members fall,' he said.
