BlackRock's head of investment research, Boivin, said that the unusually high policy uncertainty this year has disrupted the financial markets, and the Federal Reserve is powerless to solve this problem, and it has also been affected. He said that Fed Chairman Powell emphasized this point several times in the policy statement on Wednesday, pointing out that uncertainty is one of the reasons for "policy inertia." "We believe that the Fed will find it difficult to cut interest rates more than once or twice this year - even if the long-term uncertainty begins to undermine the originally healthy economic growth."
