Beyoncé’s Renaissance World Tour, her first solo tour since 2016, started on May 10 in Stockholm, with two nights at a 50,000-capacity arena. Fans from around the world took advantage of favorable exchange rates and flew in to buy tickets that were cheaper than in the United States or Britain, for example.

Mr. Grahn said in an email that he wouldn’t blame Beyoncé for the high inflation number but that “her performance and global demand to see her perform in Sweden apparently added a little to it.”

He added that the weakness of Sweden’s currency, the krona, would have added to demand as well as cheaper ticket prices. “The main impact on inflation, however, came from the fact that all fans needed somewhere to stay,” he said, adding that fans took up rooms as far as 40 miles away. But the impact will only be short-lived, as prices revert this month.

While this is a “very rare” effect, he said Sweden had seen this kind of inflationary effect on hotel prices before from a 2017 soccer cup final, when foreign teams played in the country.
