Key Takeaways
Growth Slows First: Global GDP growth is projected at 2.8% in 2026 and 3.1% in 2027 if energy prices ease from mid 2026.
Inflation Reaccelerates: G20 inflation is expected to rise from 3.4% in 2025 to 4.0% in 2026 before easing to 3.1% in 2027.
Downside Is Severe: Prolonged disruption could cut global growth to 2.1% in 2026 and 1.8% in 2027, while lifting inflation further.
