The year-on-year increase is below the 1.7 percent average
annual increase over the last 10 years.
Economists had forecast the CPI gaining 0.3 percent last
month and advancing 1.1 percent from a year ago.
The so-called core CPI, which strips out food and energy
costs, also rose 0.2 percent in June, rising by the same margin
for three consecutive months. That lifted the year-on-year core
CPI gain to 2.3 percent from 2.2 percent in May.
