How Does Big Data Impact Macroeconomic Growth and Central Bank Policies?

Big data reveals economic trends and predicts microeconomic conditions

Big data technology has revolutionized economic forecasting paradigms by enabling precise analysis of economic trends and accurate prediction of microeconomic conditions. Advanced forecasting methodologies now leverage vast datasets to identify patterns invisible to traditional analytical approaches. Research demonstrates this transformation through comparative accuracy metrics between traditional and big data methods:

The application of machine learning techniques allows researchers to create simplified models that effectively describe complex economic data sets. For instance, the new index developed using over 500 macroeconomic time series has achieved 99% accuracy in aligning with historical U.S. business cycles. Furthermore, big data technology enables economic forecasters to obtain valuable insights in significantly shortened timeframes, empowering decision-makers with real-time economic intelligence. This technological advancement has proven particularly valuable in understanding microeconomic conditions through the integration of alternative data sources like Google Trends and Google Mobility, which have contributed to innovative economic analyses in markets worldwide.

Data center investments account for 80% of US private domestic demand growth in H1 2025

The first half of 2025 witnessed an unprecedented economic phenomenon as data center investments emerged as the dominant driver of U.S. private domestic demand growth. According to research from Harvard economist Jason Furman, these investments accounted for approximately 80% of private domestic demand growth during this period, fundamentally reshaping economic dynamics.

S&P Global's comprehensive analysis revealed the stark contrast between data center-driven growth and traditional economic indicators:

For the first time in economic history, the dollar value contributed to GDP growth by AI data-center buildout surpassed U.S. consumer spending. This shift indicates a fundamental transformation in the structure of the American economy, with technology infrastructure becoming the primary growth engine.

The U.S. currently leads global data center capacity, accounting for over 40% of the worldwide total—a proportion that S&P Global 451 Research expects to increase further. As Paul Gruenwald, Global Chief Economist at S&P Global Ratings noted, "The data center boom powering the AI revolution is clearly moving the macro needle, especially in the U.S."

Non-competitive and derivative data factors influence macroeconomic growth

Non-competitive structures in data markets significantly impair macroeconomic growth through reduced efficiency and innovation. When data monopolies emerge, as seen in certain digital platforms, prices typically increase while output decreases—creating deadweight losses that restrict overall economic expansion. Research from Stanford indicates that industries operating with marginal costs below price contribute to procyclical productivity fluctuations, intensifying macroeconomic volatility.

The relationship between market structure and economic outcomes becomes clear when examining productivity metrics:

Derivative data generation presents a counterbalance to these negative effects. When data flows freely between market participants, as demonstrated by Streamr (DATA) network's decentralized P2P architecture, innovation accelerates and productivity improves. Effective data governance frameworks that mandate sharing of certain datasets—while protecting legitimate competitive advantages—have shown promise in European markets where regulatory frameworks are evolving to address monopolistic tendencies. The evidence suggests that implementing data-sharing mechanisms can transform market structure dynamics, restoring growth potential that would otherwise be suppressed by non-competitive arrangements.
