Capital expenditure in artificial intelligence is no longer just a tech sector phenomenon; it has officially become a primary engine of global macroeconomic expansion. In its latest midyear economic assessment, Bank of America (BofA) upgraded its global growth projections, citing a massive wave of AI infrastructure spending that is outpacing traditional economic drivers like consumer demand.
The Numbers: Upgraded Projections for Global GDP
According to Bank of America global economists Claudio Irigoyen and Antonio Gabriel, the global economy is now projected to expand by 3.2% in 2026 and 3.5% in 2027. These figures represent upward revisions from the bank’s previous estimates of 3.1% for 2026 and 3.4% for 2027. This bullish recalibration underscores the compounding macroeconomic effects of the artificial intelligence boom, which is driving both domestic hardware investment in the United States and a powerful export cycle across Asian manufacturing hubs.
The Shift: AI Investment Eclipses Consumer Spending
For years, US economic resilience was anchored by consumer spending. However, BofA’s data reveals that AI investment is gradually supplanting the consumer as the leading driver of US final domestic demand. While consumer spending faced headwinds in the first half of the year due to elevated energy prices and sticky inflation, tech megacaps continued to pour hundreds of billions of dollars into data centers, chips, and software. By the first quarter of 2026, AI capital expenditure emerged as the dominant force in domestic demand.
This capital-intensive cycle has also revitalized emerging-market exporters. For instance, South Korea’s Kospi Composite index (^KS11) has soared by nearly 100% since the beginning of the year, powered by semiconductor giants SK Hynix (000660.KS) and Samsung Electronics (005930.KS). BofA notes that the demand for machinery parts and hardware has transformed the export economies of China and the rest of emerging-market Asia into critical nodes of this global expansion.
Macro Risks: Federal Reserve Policy and Geopolitics
Despite the optimistic growth upgrades, the macroeconomic landscape remains fraught with risk. BofA warns of a potential “disorderly tightening of financial conditions,” particularly as loose financial conditions and AI-driven stock market gains fuel K-shaped economic dynamics. To combat persistent inflation, BofA economists project that the US Federal Reserve will implement 75 basis points in rate hikes by the end of 2026.
Furthermore, geopolitical tensions in the Middle East and risks of escalation in the Iran war continue to threaten energy stability. While temporary deals have dissipated immediate conflicts, BofA warns that low global oil inventories offer little buffer against future energy price shocks, which could negatively impact developed markets by 2027.
Frequently Asked Questions (FAQ)
How does AI investment directly increase global GDP?
AI drives GDP through massive capital expenditure (Capex) on physical infrastructure, including data centers, specialized semiconductors, and energy grid upgrades. This spending creates a multiplier effect, boosting manufacturing and exports in countries like China and South Korea that supply the hardware supply chain.
Why is consumer spending losing its lead in driving economic growth?
While consumer spending remains resilient, it has been hamstrung by persistent inflation, declining real income, and energy price volatility. In contrast, corporate investment in AI is viewed as a secular necessity, leading megacap technology firms to maintain high levels of capital deployment regardless of consumer headwinds.
What are the primary risks to this AI-driven economic outlook?
The main threats include hawkish monetary policy, with Bank of America forecasting 75 basis points of Federal Reserve rate hikes by the end of 2026. Additionally, geopolitical risks in energy-producing regions and the potential for a K-shaped recovery could lead to a disorderly tightening of global financial conditions.
