Artificial Intelligence Spending Threatens to Keep Global Interest Rates High

Tokyo, Monday, 5 October 2026.
Massive capital investments in artificial intelligence infrastructure are driving up corporate bond issuance, threatening to keep global real interest rates elevated before productivity gains materialize.

The Demand Shock Dynamics

On Monday, 5 October 2026, Bank of Japan Deputy Governor Shinichi Uchida addressed the ECONDAT 2026 Fall Meeting in Tokyo, characterizing the current AI boom as a significant macroeconomic force [3]. Uchida described artificial intelligence as a “big positive demand shock” that has subsequently put upward pressure on both the economy and prices [2][4][5][7]. This assessment suggests that while equity markets have rallied on AI enthusiasm, easing some financial conditions, the underlying demand surge is reshaping traditional monetary policy parameters [6]. The central bank notes that this shock is distinct because it simultaneously stimulates activity through investment while potentially complicating inflation targets [7].

Capital Intensity and Financing Costs

The scale of investment required to sustain this technological shift is unprecedented, with Deputy Governor Ryozo Himino estimating annual U.S. IT-related capital investment at approximately $1.7 trillion as of August 2026 [1]. Major technology corporations, including Amazon, Microsoft, Alphabet, Meta, and Oracle, are projected to incur total capital expenditures of roughly $800 billion in 2026, a significant portion dedicated to AI infrastructure [1]. To finance these expenditures, firms are increasing corporate bond issuance, which exerts upward pressure on long-term interest rates even as equity valuations rise [5]. This dynamic creates a scenario where heavy capital expenditure for semiconductors, servers, and power grids precedes actual productivity gains, potentially sustaining higher financing costs in the near term [1].

Policy Implications and Monitoring

Bank of Japan officials acknowledge that determining the ultimate impact on the neutral interest rate, or r*, remains difficult at this stage [3]. Uchida stated that the central bank does not yet have a clear answer on whether AI will permanently raise the natural rate of interest, necessitating continued monitoring of economic and financial indicators [1][6]. Policy meetings now frequently include discussions on AI’s implications for the output gap and financial stability, marking it as a major focus alongside geopolitical and climate risks [3][6]. Until productivity gains materialize to offset the initial capital outlay, investors and policymakers must navigate a landscape where technological success does not automatically guarantee cheap capital [1].
