AI, Oil, and a Changing Global Economy

AI, Oil, and a Changing Global Economy

Two powerful forces are shaping the economic and investment landscape. The first, as we anticipated in the Vanguard Economic and Market Outlook for 2026, is artificial intelligence, which is supporting above-trend U.S. growth. The second is the oil shock stemming from conflict in the Middle East, which has weighed on global growth and added to inflationary pressures. These forces are driving an unusual degree of divergence across regions. While the U.S. appears positioned for structural transformation, other major economies face a more challenging balance between technological change and elevated energy costs.

AI is central to our investment thesis. It is already contributing to stronger U.S. corporate earnings expectations, though elevated valuations suggest we could see periodic corrections as the transformation unfolds. Importantly, AI appears increasingly likely to become a transformative technology, creating meaningful economic upside while also setting conditions for a potential rotation in market leadership.

U.S. economy poised for structural transformation

Our most notable call now is for 3% U.S. GDP growth in 2027, well above consensus forecasts. This reflects what we view as a structural transformation rather than a cyclical acceleration. Moreover, while six months ago we forecasted that the U.S. economy would eventually grow by 3%, that call was based on the investment trajectory relative to past technological revolutions.

AI investment to date, however, suggests we are in the early stages of a profound economic shift that could reshape productivity over the coming decade. Recent data show AI-related capital expenditure both exceeding its elevated late-2025 levels and tracking above our predictions for 2026. This wave of investment resembles historic periods of large-scale capital expansion, such as the railroad buildout in the 19th century and the late-1990s technology boom.
