Global inflation surged once again in May, according to new data from the Organization for Economic Cooperation and Development (OECD).

The Paris-based group reported that annual inflation for the OECD area rose to 9.6% in May, up from 9.2% in April — marking the sharpest price rise since 1988.

The latest increase was “largely driven by food and energy prices,” it noted.
