San Marinos GDP (PPP) is projected at $2.9 billion in 2025, though data is limited. San Marinos economy relies on tourism, financial services, and small-scale manufacturing. The PPP adjustment moderates GDP due to a high cost of living. Close ties with Italy support trade, but reliance on tourism and banking poses risks. San Marino is diversifying into technology and green finance, though its small size limits economic scope. Regulatory pressures and infrastructure needs require focus to maintain economic stability.
