The digital transformation of the banking sector represents one of the greatest achievements of recent years. At the international level, it is impossible to stop the digitalization of all processes, including the use of the most modern technologies and the introduction of software to optimize their operations. Digital transformation of the banking sector is, first, a mandatory step for its further development. This is a system-wide process, not just a business alternative. Ecuador is a small economy dependent on oil exports, rather open and dollarized. Ecuador's monetary policy restricts macroeconomic policy options for responding to external shocks and transfers this task to fiscal policy, acting as an important macroeconomic tool for influencing the level of domestic demand. Ecuador's banking market is characterized by uneven, but stable number of banks. In general, the Russian financial industry is highly mature in terms of the introduction of digital solutions. On the one hand, local banks already have a developed physical infrastructure. On the other hand, the largest of them have created a developed ecosystem of digital channels. At the same time, it would be very interesting to compare the characteristics of the digital transformation of the Russian banking sector with foreign ones. For comparison, this study takes the banking sector of Ecuador.
