The ACPR conducted in 2017, and published in early 2018, two studies on the digital revolution, one dedicated to the insurance sector and the other to the banking sector. It seemed worthwhile to repeat these two studies a few years later, in order to assess developments in these two sectors. This work, which focuses on the banking sector, drew on a survey similar to the 2017-2018 one and comprising about fifty questions, that was sent to eight representative banking institutions in the French market.
