AI In his opening remarks at the ECONDAT 2026 Fall Meeting, Bank of Japan Deputy Governor Shinichi Uchida discussed how AI and big data are changing central bank analytical methods and data use, and how AI adoption may affect productivity and the labor market in both positive and negative ways. He said AI is affecting core monetary policy variables such as the output gap, financial conditions and the natural rate of interest, but that there are still no clear answers on its scope, magnitude and timing, so the Bank will continue to analyze economic and financial indicators for the time being.
