Fresh off the IMF’s October 2025 World Economic Outlook, the global growth map is flipping toward frontier frontiers—think oil gushers, reform rushes, and resource rebounds—as South Sudan blasts to the top spot with a blistering 24.3% real GDP leap, outpacing the pack on the back of revved-up crude flows and a chill in political heat.

Hot on its heels? Libya’s clawing back at 15.6%, fueled by steady oil ramps and rebuild buzz that’s turning war scars into boom blueprints. Guyana keeps its pedal down in third, clocking 10.3% on that endless black-gold wave, cementing its rep as a pint-sized powerhouse.

The vibe? A seismic shift to raw-material riches and makeover markets, with Africa stealing extra shine: Guinea, Ethiopia, and Rwanda all revving 7%+ via infra injections, farm flexes, and post-plague pivots. Georgia ties in at 7.2%, rounding out the reform squad.
