Abstract

As in the rest of the world, inflation in CEMAC surged more quickly and persistently than expected during the 2021–23 period. This paper examines the drivers of inflation dynamics and the contribution of global shocks to inflation persistence in CEMAC. We use a Phillips curve framework combined with the local projections method. Our results confirm the prominent role of global factors in driving inflation dynamics. Global commodity food and oil price fluctuations, and shipping costs are the main factors explaining the large variability in headline inflation. Further, we find that global price shocks have sizable and persistent effects on domestic headline inflation, with differences in the magnitude and speed of pass-through. The pass-through from commodity food price fluctuations to headline inflation is higher and more persistent than that of other global price shocks, reflecting the large share of food in the consumption baskets, which makes inflation more vulnerable to direct effects of international food shocks, but also larger second-round effects.
