G20 inflation is projected at 4.1% in 2026 and 3.6% in 2027.The OECD, an international organisation, says the world economy handled the energy shock from the conflict in the Middle East better than expected. But prices are rising more easily again, and the “cushions” that softened the shock are wearing thin, so it is too early to relax.
