All that stimulus is sending inflation higher

Worries about sudden inflation spikes are keeping investors and economists up at night. Their concerns aren't baseless: Inflation is indeed rising in the United States, government data for producer prices showed Friday.

The question on everyone's mind remains: Is inflation a temporary sugar rush from stimulus or is it here to stay? The US Producer Price Index, which measures sale prices for goods and services, climbed 1% on a seasonally adjusted basis in March, the Bureau of Labor Statistics announced Friday. That was a steeper rise than February and greater than economists had expected.
