On paper, inflation in Honolulu during the first half of this year was barely discernible, and at this pace, stands to end 2015 at its lowest level since 2009. Good news indeed.

This low inflation rate — just 0.7 percent up from the same period last year — is thanks largely to big drops here in gas and electricity prices, which are certainly welcomed by consumers. But, those energy easings on the pocketbook are countered by rising costs for food and beverages (up 4.2 percent from the same period a year ago) as well as for medical care (up 4.8 percent) and education/communication (up 3.1 percent).

Such is life on the inflationary treadmill: two steps forward, three steps back.
