The OECD on Tuesday raised its global growth outlook, citing resilience across several economies despite heightened trade frictions and policy uncertainty.
The organisation now projects global GDP to expand 3.2% in 2025, up from its June estimate of 2.9%.
That would still mark a slight slowdown from 2024’s 3.3% pace, while expectations for 2026 remain at 2.9%.
The US forecast was lifted modestly to 1.8% growth in 2025, compared with 1.6% predicted earlier, though still down sharply from the 2.8% expansion recorded in 2024.
Growth is projected to ease further to 1.5% in 2026.
