On the heels of a downward revision to first-quarter U.S. GDP growth last month, full-year economic growth projections are coming down. The big question mark that arises as a result of these downward revisions is how the Federal Reserve will react?

The International Monetary Fund reduced its estimate for full-year U.S. GDP growth to 2.0 percent from 2.8 percent. The World Bank has lowered its estimate to 2.1 percent from 2.8 percent, based in no small part on the weak first quarter.
