The Federal Reserve held its benchmark interest rate unchanged at its March 17-18 meeting, a move that investors had anticipated due to still-sticky inflation and a stable job market. However, Fidelity revealed that the Fed is still considering the implications of the Iran conflict and recent swings in energy and labor data. The company also highlighted three key unknowns to watch for the Fed's next moves. The job market has continued to show sluggishness, but there is no sign of a sharp deterioration. With inflation still above target, the data didn't give the Fed a persuasive reason to resume cutting rates. The outlook for Fed policy becomes more uncertain as the oil prices rise.
