Economy of  Spain

According to a report by the European Commission, the Spanish economy is projected to grow at 2.5% in 2023, 1.7% in 2024, and 2.0% in 2025. These projections indicate that while the economy is expected to continue growing, the pace might slow down slightly in 2024 before picking up again in 2025 as inflation is expected to decrease to 3.2% in 2024 from 3.4% in the previous year. Interest rate hikes impact the domestic demand and declining debt ratios may also restrain growth. GDP growth is projected to accelerate in 2025 due to increased investment by corporations, external demand, and ease in financing conditions.
