Federal Reserve Governor Lisa Cook identified the artificial-intelligence buildout as one of her main inflation concerns for 2027, warning that the investment wave may create price pressures that do not fade quickly. Speaking with New York Fed President John Williams on Thursday, Cook said the physical expansion behind AI could produce persistent supply constraints even if the technology ultimately improves productivity. Her remarks put the cost of data centers, chips, electrical equipment and construction capacity directly into the monetary-policy debate.
Cook’s concern centers on timing. AI is widely expected to improve efficiency over the longer term, but the infrastructure required to deliver those gains must be built first. Reports on her remarks said rising demand has already affected prices for chips, electrical components and materials used in data centers. Cook said she remains uncertain about when productivity gains will begin generating disinflation and where the next bottlenecks will appear. That sequence matters because an investment boom can strengthen demand and strain limited supplies before any economy-wide efficiency benefit becomes visible.
The comments come against an already difficult inflation backdrop. Cook joined the Federal Open Market Committee’s unanimous decision in September to raise the policy rate by 25 basis points, a move intended to support a timelier return of inflation to the Fed’s 2% objective. Inflation measured by the Fed’s preferred gauge was reported at 3.4% in August and has remained above the central bank’s target for more than five and a half years. Persistent AI-related costs would add another complication as officials judge whether existing restraint is sufficient.
Cook also placed the AI expansion within a broader pattern of more frequent supply shocks. She said such disruptions have sometimes proved more persistent than policymakers expected, while geopolitical tensions and the Middle East conflict could further affect supply chains. The traditional central-bank approach has often been to look through temporary supply shocks because higher interest rates cannot produce more oil or resolve a war. Cook suggested the appropriate response may now depend more closely on which sectors are affected and how widely the pressure spreads through the economy.
What it means for traders: Cook’s remarks add a new supply-side risk to the outlook for US inflation and interest rates. If AI infrastructure demand continues to lift input costs before productivity improves, inflation could remain above target for longer, keeping the path of Federal Reserve policy sensitive to incoming price and labor data. A broader or more persistent spillover would be relevant for the US dollar and Treasury yields, while evidence that bottlenecks are easing or productivity is arriving sooner would weaken that particular inflation concern. The comments describe a risk scenario rather than a new policy decision.
Attention now turns to evidence of whether AI-related price pressure remains concentrated in technology and construction inputs or spreads into the wider economy. Traders will also watch the September US employment report, subsequent inflation releases and additional Fed commentary for indications of how officials balance resilient activity against elevated prices. Cook’s distinction between near-term investment pressure and longer-term productivity gains will remain important: the timing of that transition may influence how long monetary policy must stay restrictive.
