Artificial intelligence investment has become a critical driver of global economic growth, with the U.S. benefiting disproportionately from massive outlays by major technology firms, according to Barclays Private Bank’s Chief Market Strategist Julien Lafargue.
Lafargue estimates that between 50% and 75% of recent U.S. economic growth can be directly or indirectly attributed to AI-related investments. The cycle remains in its early stages, he notes, though growth rates in spending are expected to moderate over time. The momentum is unlikely to fade soon, driven by competitive pressures on corporations, investor demand, and strategic government support amid the U.S.-China technology rivalry.
While Lafargue anticipates potential corrections in overvalued segments such as semiconductor and memory chip manufacturers, he views these as normalizations within a broader, long-term trend rather than the end of the AI investment cycle. The core investment thesis, he argues, is not AI itself but the productivity gains it enables. Improved efficiency and margin expansion across industries could ultimately help address structural fiscal challenges, including rising sovereign debt in many advanced economies.
Europe’s prospects remain subdued by comparison. Despite recent initiatives in infrastructure and defense spending in Germany, Lafargue cautions that tangible economic benefits will take years to materialize. Political uncertainty, including upcoming French presidential elections in 2027 and fragile governing coalitions in Germany, further dampens investor confidence. The Swiss economy, however, is positioned more favorably due to its stability, though its equity market lacks exposure to the current AI-driven rally.
Looking ahead, Lafargue expects AI adoption to expand beyond infrastructure—such as data centers and chips—into traditional sectors. Healthcare, in particular, holds significant potential for productivity gains through drug discovery and diagnostics. Over time, Europe and Switzerland may benefit more than currently anticipated as AI diffuses across industries.
China, often underestimated by investors, could emerge as a surprise leader in the next phase of AI development, Lafargue suggests. While facing structural headwinds in consumption and real estate, China possesses strong foundations for advancements in robotics and physical AI. Its combination of advanced AI models and industrial manufacturing capabilities could position it at the forefront of future investment opportunities.
The U.S. remains the primary catalyst for global growth, Lafargue notes. Political dynamics, including November’s U.S. congressional elections, may influence fiscal policy, with potential implications for equity markets. Regardless of short-term outcomes, Europe’s trajectory remains closely tied to American economic performance, he adds.
