'It's not just Taylor Swift': ECB's Lagarde says Eras Tour is not alone in keeping euro zone inflation high

European Central Bank President Christine Lagarde said Tuesday that Taylor Swift's Eras Tour is not alone in keeping inflation high across the euro zone.

Lagarde said that while services inflation remained sticky last month in the 20-nation bloc, coinciding with the European leg of Swift's sell-out tour, it could not be attributed to just one performer.

"It's not just Taylor Swift, you know," Lagarde told CNBC's Sara Eisen in Sintra, Portugal. "Others have come as well."

Lagarde was responding to a question about whether Swift's tour boosted services inflation, one of the ECB's closely watched measures.

The economic impact of Swift's sell-out tour has been well documented and comes amid concerns that central banks may not be out of the woods yet in their fight against inflation.

Terms such as "Swiftflation" and "Swiftonomics" emerged last year following a surge in spending on services such as hotels, flights and restaurants around her performances. Analysts have even suggested that the impact on key U.K. inflation readings during her London dates could prompt the Bank of England to delay an anticipated September interest rate cut.

However, increased consumer spending around major music tours for other artists, such as Bruce Springsteen, Pink and Sting, are also said to be providing an economic boost.

"Services is the difficult one," Lagarde noted, adding that "the jury is still out" on whether that stickiness is permanent.

Services inflation in the euro zone held steady at 4.1% in June, the European Union's statistics agency said earlier Tuesday. Core inflation, excluding the volatile effects of energy, food, alcohol and tobacco, stayed at 2.9% from the prior month, just above the 2.8% economists had forecast.
