Cleveland Federal Reserve President Beth Hammack warned that surging demand for artificial intelligence infrastructure could add to inflationary pressures and may force the Federal Reserve to raise interest rates again if price growth remains elevated. Speaking to CNBC from the European Central Bank conference in Sintra, Portugal, Hammack said inflation remains above the Fed’s 2% target and warned that persistent price pressures tied to AI spending could complicate monetary policy.

"We’ve got inflation that’s too high, and it’s been too high for the past five years," Hammack told CNBC’s Sara Eisen. "When I look at policy, if that continues, it may mean that we need higher interest rates to bring inflation back down to target."

Hammack pointed to aggressive spending on AI-related infrastructure, particularly data centers, as a sign that economic demand remains strong and could continue putting upward pressure on prices. She cited a manufacturer in her district involved in electric switching equipment for data centers and said demand remains unusually strong. "What they say is that the demand is insatiable, that these companies, these hyperscalers, will pay almost any price for those inputs, and they need things built yesterday," Hammack said.

Recent data from Data Center Watch showed at least 75 AI data center projects worth roughly $130 billion were blocked or delayed in the first quarter of 2026 as infrastructure expansion accelerated. Hammack said she is not seeing much evidence that high borrowing costs are slowing corporate investment. "When I look broadly, particularly around large companies, I’m not seeing a lot of restraint in the economy," she said.

Hammack’s comments contrast with Fed Chair Kevin Warsh, who has argued AI could eventually reduce labor costs and become disinflationary through productivity gains. Hammack is a voting member of the Federal Open Market Committee this year. The Federal Open Market Committee kept rates unchanged earlier this month, though policymakers’ latest projections indicated one quarter-point rate increase could still be possible later this year.

Global financial markets reacted positively after a Donald Trump administration official confirmed that the U.S. and Iran would "stand down" following a recent exchange of military strikes, allowing vessels to move freely through the Strait of Hormuz. According to the Wall Street Journal, Trump was briefed on all-out war options against Iran but opted to continue with diplomatic talks, and is willing to extend the Iran nuclear deal deadline beyond August 18. The announcement helped lift oil prices to nearly $70 per barrel and drove U.S. stock futures higher, even as Iran has not publicly confirmed the pause in hostilities. The development comes amid ongoing technical talks regarding a memorandum of understanding signed earlier this month, aimed at reopening the strategic waterway and advancing negotiations over Iran's nuclear program.

Diplomatic Developments

A senior U.S. administration official stated that technical talks on implementing the memorandum remain "on track" and that deconfliction channels between the two sides remain operational. American and Iranian officials are scheduled to meet in Doha, Qatar, for further discussions. The latest developments follow a tense period during which President Trump warned of additional military action if Iranian strikes continued, while Iran cautioned that any ceasefire violations would "result in the complete halt of all diplomatic processes." Despite the fragile nature of the agreement, Trump's decision to pursue talks over military escalation — and his willingness to extend the nuclear deal deadline beyond August 18 — signals a continued, if cautious, diplomatic approach.
