CPI: March: +0.6%, April: +0.8%, 12 months: +4.2%
This is the largest 12-month increase since a 4.9-percent increase for the period ending September 2008.
Core CPI (CPI less food and energy): April: +0.9%, 12 months: +3.0%,
The index for used cars and trucks rose 10.0 percent in April. This was the largest 1-month increase since the series began in 1953, and it accounted for over a third of the seasonally adjusted all items increase. The food index increased in April, rising 0.4 percent as the indexes for food at home and food away from home both increased. The energy index decreased slightly, as a decline in the index for gasoline in April more than offset increases in the indexes for electricity and natural gas.
Over the past 12 months:
The energy index rose 25.1 percent , and the food index increased 2.4 percent. Gasoline prices up 49.6% ((and this is long long before the Colonial Pipeline shutdown. Just wait for the May report -Progree))
