The U.S. economy added just 75,000 jobs in May, fewer than the 175,000 economists were expecting, while the unemployment held at 3.6%, a 50-year low, the Labor Department said on Friday.

Why it matters: Job growth screeched to a near halt after stellar growth in April. This is a key factor that the Fed will consider, meantime the market expects the central bank to cut rates. Every single data point is make or break for those watching for cracks in the economic expansion that‘s on pace to be the longest in U.S. history.
