The US market is currently experiencing an unprecedented wave of AI infrastructure investment, with the four tech giants—Amazon, Meta, Microsoft, and Alphabet—investing over $700 billion to deploy core hardware for data centers, semiconductors, and computing power, reshaping the US economic landscape. This epic capital expenditure has sparked fierce debate within the Federal Reserve, with two distinct camps arguing over the medium- to long-term impact of AI investment on inflation, creating crucial uncertainty for future monetary policy.

Walsh's optimistic view: AI improves efficiency and increases production, and can curb inflation in the long run.

Newly appointed Federal Reserve Chairman Kevin Warsh holds a firmly optimistic view of the AI industry's benefits and is a key figure within the Fed who believes AI can empower the economy and curb inflation. He consistently adheres to a core logic: large-scale AI infrastructure development will comprehensively improve labor productivity across the US, not only helping companies reduce costs and increase efficiency and boost operating profits, but also driving steady wage growth. Ultimately, through continuous expansion of production capacity and supply, this will offset market price pressures, stabilizing prices and suppressing inflation in the long term. Warsh has repeatedly affirmed this view in public, pointing out that the market is currently in a super cycle of AI capital expenditure. The current surge in demand is a short-term phenomenon; over time, the benefits of AI-related production capacity and supply will continue to be released, gradually alleviating cost pressures across the entire industry chain. In his view, this multi-billion dollar AI investment is not a driver of inflation, but rather a core tool for optimizing the US economic structure, eradicating long-term high inflation, and a key force in breaking the recent pattern of inflationary volatility in the US.

Most FOMC members have the opposite view: AI investment could fuel stubborn inflation stickiness.

In stark contrast to Warsh's optimistic assessment, most Federal Reserve policymakers remain highly vigilant about the inflationary risks associated with AI infrastructure. A majority of Federal Open Market Committee (FOMC) members explicitly disagree with the logic of AI lowering inflation. This is evident in the minutes of the Fed's June policy meeting released on July 8th—Warsh's first complete meeting record since taking office—showing a significant increase in Fed officials' vigilance regarding upward inflation risks. The massive capital expenditure on AI has become a new core variable driving up US inflation stickiness, following the geopolitical conflict with Iran and existing tariffs. Notably, the Fed's policy meetings in the first half of the year never specifically discussed the impact of AI infrastructure; the June meeting marked the first time it was listed as a key topic, signifying that the inflationary risks posed by AI investment have escalated from a hidden market risk to a core issue that the Fed's monetary policy must consider. Most members agreed that the continued investment in AI infrastructure by leading technology companies is not a one-off investment impulse, but rather a long-term, sustained, and rigid demand. Large-scale computing power construction will continue to drive up costs across the entire industry chain, including semiconductors, specialized hardware, software services, and electricity, and the signal that these costs are being transmitted to the end-consumer market is becoming increasingly clear. The most typical market evidence is that in June, Apple raised prices across its entire Mac and iPad product line due to chip supply shortages and rising component procurement costs, with the lowest price increase reaching $150 per item. This phenomenon confirms the concerns of Federal Reserve officials: the increased supply chain costs brought about by AI infrastructure construction have begun to impact consumer spending, which will prolong the upward cycle of US inflation, solidify inflation stickiness, and generate persistent and stubborn inflationary pressures.

Fed officials take a hawkish stance: Structural inflation may force interest rate hikes.

In addition to most FOMC members, several senior Federal Reserve officials have also continued to issue risk warnings. While New York Fed President John Williams claimed that short-term inflation may have peaked, he also clearly stated that the sustained large-scale capital expenditures in AI will create long-term, stable new market demand, easily disrupting the existing supply-demand balance and creating structural inflationary pressures that are difficult to resolve. This type of systemic risk is not a short-term disturbance, and the Fed cannot selectively ignore it; it may even force the central bank to initiate interest rate hikes. Fed Governor Lisa Cook similarly warned that this epic investment cycle in the AI industry will comprehensively raise the pricing level of the entire industry chain, providing a sustained upward push for US inflation.

Wall Street is divided: AI profitability has not yet materialized, and risks of bubbles and inflation coexist.

Beyond the Federal Reserve, Wall Street also holds differing opinions on the returns and inflationary impact of massive AI investments. Jim Cramer, a well-known financial commentator and former hedge fund manager, continues to moderate his risk appetite, stating explicitly that "the current AI sector lacks real, tangible profit data to support its growth, and the commercial value of these massive investments has not yet been realized. Until profits materialize, the market's bearish logic will remain valid, and the inflationary side effects of AI investment are far from being fully priced in." It's worth noting that, considering the current market fundamentals, despite widespread concerns about a valuation bubble in the AI sector, leading technology companies have not scaled back their investments. AI will remain a core driver of US corporate capital expenditures for the next few years. Wall Street institutions estimate that global AI capital expenditures will reach $800 billion to $900 billion in 2026 and exceed $1 trillion in 2027. This infrastructure boom will continue to unfold, and the risk of inflation will persist for a long time.

Current US Inflation Status and Outlook for Federal Reserve Interest Rate Policy

Considering the current inflation fundamentals, US inflation has experienced several years of dramatic fluctuations, reaching a 40-year peak in 2022 before declining somewhat. However, influenced by factors such as the geopolitical conflict with Iran affecting energy prices and existing tariffs suppressing the economy, the inflation center has remained above the average of the past decade. In June, the US CPI year-on-year growth rate fell to 3.5%, a decrease of 0.4 percentage points from May, temporarily dispelling market expectations for a short-term interest rate hike, but still far exceeding the Fed's 2% inflation target. Currently, the Fed is maintaining its benchmark interest rate at the 3.50%-3.75% range, a level that has remained stagnant since its adjustment last December. Combining the Fed officials' inflation assessments and internal disagreements, the future interest rate path is clear: Warsh, adhering to the long-term logic of AI improving efficiency and reducing inflation, tends to maintain a loose monetary policy and postpone tightening; however, most FOMC members and senior officials are closely monitoring the structural and persistent inflationary pressures brought about by AI investment, coupled with the uncertainty of energy and geopolitical risks, and the market has already priced in an expected 25 basis point rate hike by the end of the year. Overall, the internal divisions within the Federal Reserve triggered by AI infrastructure will be a key variable dominating the Fed's monetary policy in the fourth quarter and influencing the performance of US stocks and bonds. If AI-driven inflation continues to intensify, the Fed is highly likely to break its current wait-and-see stance and restart interest rate hikes to tighten monetary policy in order to hedge against long-term inflation risks. For long-term investment assets such as gold, changes in interest rates directly affect their valuations and prices, making studying the Federal Reserve an essential course for investors.
