American families are growing sharply less optimistic about the economic outlook, but the Federal Reserve may be loathe to respond aggressively to a weakening economy in light of increasing worries that the Trump administration's trade policy will boost already elevated inflation.

The Fed is not expected to cut interest rates at the conclusion of its next meeting on March 19, but there may be clues to the timing of the next cut.
