It has also upgraded its 2026 forecast by 0.2 percentage points to 3.9%. A recent Reuters poll anticipates Saudi Arabia to record 3.8% growth this year. Meanwhile, the World Bank maintained its June estimates of 2.8% growth for 2025 and 4.5% for 2026.

ICYMI- The Kingdom’s real GDP grew 3.9% y-o-y in 2Q 2025, buoyed by a 4.6% growth in non-oil activities.

Zooming out: Globally, the OECD raised its 2025 growth forecast to 3.2% from 2.9%, though output is expected to moderate from that figure to 2.9% in 2026 as trade and investment weaken under high tariffs and political uncertainty.
