AI Fuels Global Growth: Bank of America Elevates Economic Forecasts Amid Shifting Drivers

Bank of America has significantly upgraded its global economic growth projections, citing the pervasive and accelerating influence of the artificial intelligence (AI) investment boom. In a midyear report, the financial giant’s strategists outlined a more optimistic outlook, recalibrating their expectations for the coming years.

Previously, global growth estimates stood at 3.1% for 2026 and 3.4% for 2027. However, driven by persistent economic tailwinds, BofA now forecasts global expansion of 3.2% in 2026 and 3.5% in 2027. This upward revision underscores AI’s pivotal role, increasingly positioned as the central engine of global economic activity.

AI’s Ascendancy Over Traditional Consumer Spending

A notable shift in economic dynamics has emerged, with AI investment supplanting consumer spending as the primary force behind US final domestic demand growth. This critical metric, representing the total expenditure on goods and services within the domestic economy, traditionally relies heavily on robust consumer activity. However, BofA’s data reveals that AI’s contribution has become disproportionately significant through 2025 and into 2026.

While consumer spending remains a foundational element of any thriving economy, the sheer scale of investment in AI technologies—including the development of advanced computing infrastructure, specialized hardware like GPUs, and innovative software solutions—has begun to overshadow consumer-led demand in driving incremental growth. This trend experienced a brief mean-reversion in late 2025, but by the first quarter of 2026, AI firmly re-established its dominance as the leading growth catalyst.

Global Reach: Asia’s AI-Driven Export Surge

The economic impact of the AI investment surge extends far beyond US borders, creating a global ripple effect. The increased demand for sophisticated AI hardware and related components has spurred a significant export boom in key Asian economies. China, a major hub for manufacturing and supply chain operations, benefits from the production and export of numerous machinery parts essential for AI infrastructure. Similarly, other emerging-market economies in Asia are experiencing a boost due to their integration into the global technology supply chain.

A prime example of this phenomenon is South Korea. Its Kospi Composite index (^KS11) has witnessed an astounding nearly 100% rise since the beginning of the year. This index is heavily weighted towards the semiconductor sector, with industry giants like SK Hynix (000660.KS) and Samsung Electronics (005930.KS) at the forefront. Their robust performance underscores the immense global demand for the high-end memory chips and other components crucial for AI development.

Persistent Headwinds and Monetary Policy Outlook

Despite the optimism surrounding AI, the economic landscape is not without its challenges. Global economists Claudio Irigoyen and Antonio Gabriel highlight several risks that could temper this growth. Consumer spending, while projected for “robust growth” in the latter half of the year, has faced headwinds from war-driven surging energy prices and stubbornly high US inflation. These factors erode real income and purchasing power, potentially constraining household expenditure.

The persistent inflation scenario raises the likelihood of aggressive monetary policy responses from the US Federal Reserve. BofA economists predict 75 basis points in interest rate hikes by the end of 2026. Such tightening measures aim to cool the economy and control inflation, but they also carry the risk of a “disorderly tightening of financial conditions,” potentially triggering volatility in stock markets and impacting overall economic stability. The economists also caution that while a temporary peace deal might alleviate immediate concerns from the Iran war, the risk of escalation remains, threatening global oil supplies and, consequently, energy prices.

Ultimately, the narrative for the global economy in the coming years appears inextricably linked to the trajectory of AI development and investment, albeit with critical traditional economic and geopolitical factors still capable of shaping its path.

Frequently Asked Questions (FAQs)

• What is driving Bank of America’s upgraded global growth forecast?

  Bank of America revised its global growth forecasts upward primarily due to the accelerating AI investment boom, particularly in the US, and the subsequent AI-driven export cycle in Asian economies, alongside mildly lower oil prices.

• How is AI impacting US economic growth compared to consumer spending?

  AI investment has increasingly become the primary driver of US final domestic demand growth, surpassing traditional consumer spending, especially observed in Q1 2026, according to Bank of America data. This indicates a shift in the fundamental components fueling economic expansion.

• What are the main risks to this positive global economic outlook?

  Key risks include the increased likelihood of Federal Reserve rate hikes (BofA predicts 75 basis points by end of 2026) due to persistent US inflation, which could lead to a disorderly tightening of financial conditions. Geopolitical tensions, such as potential escalation of the Iran war affecting oil markets, also pose a significant threat. These factors could create K-shaped dynamics, where some sectors thrive while others struggle.
