Fed's Lisa Cook Flags AI Inflation as Top 2027 Risk Amid Data Center Boom

Lisa Cook Identifies AI Inflation as Major 2027 Concern

Federal Reserve Governor Lisa Cook has flagged AI-driven inflationary pressures as one of her primary concerns for 2027, warning that the massive infrastructure buildout may create price pressures that won't resolve quickly1

1

. Speaking at an event with New York Fed President John Williams, Cook stated that "the AI build out is potentially creating inflationary pressures that may not resolve very quickly," marking this as "one of the main things that concerns me right now for 2027"1

1

. The Federal Reserve Governor's warning comes as inflation by the Fed's targeted measure reached 3.4% in August, remaining above the central bank's 2% goal for more than 5-1/2 years1

AI Demand Drives Sector-Specific Price Pressures

During a keynote speech at Oakland Tech Week, Cook detailed how AI demand has caused prices for chips, computers and software to surge over the past year3

3

. She noted that these steep price increases reflect a shift in demand toward AI-related sectors rather than an increase in economy-wide demand3

3

. Cook argued that attempting to fight sector-specific price pressures with monetary policy "could be a mistake" since the Federal Reserve's tools are too blunt to target narrow sectors2

2

. She expects supply chains will adjust and resolve these sector-specific inflation issues without policy intervention3

Data Center Buildouts Create Economy-Wide Cost Increases

More concerning for monetary policy are signs that AI infrastructure investment is pushing up costs throughout the broader economy2

2

. Cook explained that data center buildouts rely on inputs like construction labor and energy that are broadly used across many sectors3

3

. As a result, increased AI demand could introduce price pressure to those other sectors3

3

. Cook pointed to concrete evidence of this broadening effect, noting that electricity and water costs have each risen approximately 5% over the past year5

5

. Core-goods prices are running above a 3% annual pace this year, with companies having spent only a small fraction of roughly $2 trillion in announced investment plans5

Productivity Gains Face Uncertain Timing

While Cook voiced a view shared by many at the Federal Reserve that AI will boost productivity in the longer term, she expressed concern about timing4

4

. "I worry about when the productivity gains that would produce disinflation will come, and where the supply bottlenecks are going to be next," Cook stated4

4

. She anticipates that productivity gains will provide modest disinflation within the next few years, but crucially added that she does not expect those effects to arrive in time to offset the broadening inflationary pressure later this year2

2

. Cook warned that AI-driven productivity could eventually coincide with a painful transition as workers move between jobs and skills5

Interest Rate Hikes Remain on the Table

Cook joined a unanimous vote last month at the Federal Reserve to raise the policy rate by a quarter of a point to support a "timelier" return of inflation to the Fed's 2% goal1

1

. The decision raised rates by 25 basis points to 3.75%-4%, marking the first increase since 20235

5

. Cook said total inflation reached an estimated 3.8% in the 12 months through August, while core inflation stood at 3.4%5

5

. Traders are pricing in roughly a 70% chance that the Federal Open Market Committee will again hike interest rates by a quarter point at its next meeting in late October3

Geopolitical Conflicts Add to Supply Shock Concerns

Cook also highlighted how geopolitical considerations, including the conflict in the Middle East, could further crimp supply chains and add to inflationary pressures4

4

. She noted that increasingly frequent supply shocks have had surprisingly persistent effects and become more salient for policy decisions1

1

. Cook explained that the Federal Reserve's conventional view used to be to "look through" supply shocks because tighter monetary policy wouldn't affect oil prices or wars, but could slow down employment and output4

4

. However, she suggested that the "optimal response" could now be different, depending on the sectors affected by the supply shocks4

4

. Cook expects higher oil prices and Middle East supply-chain disruptions to keep adding inflation pressure in coming months5

5

. Despite these challenges, Cook stated that "the labor market appears to be well positioned to handle an increase in rates," citing August unemployment of 4.1%5
