In our April 28 update, we emphasized that our forecast was in "transition" from stronger to weaker in large part depending on the behavior of bank credit. This month we have made the transition to a significantly weaker outlook, not only because of the current behavior of bank credit, but also because of the current behavior of the overall economy. With regard to the latter, even before the Federal Reserve has terminated its second round of quantitative easing - that is, even before the Fed has taken its foot off the monetary accelerator - the underlying pace of U.S. economic activity already appears to be coming in weaker than we had anticipated.
