Resumen: "Financial technology" or "FinTech" has transformed the financial sector, changing how incumbent financial institutions interact with each other and with consumers. The interlinkage of finance and technology has given rise to a new type of digital products and services which are highly demanded by society. This study aims to analyze how the new era of FinTech has emerged in the developed and developing world. FinTech has posed important challenges for market participants such as banks in balancing their potential benefits with the new approaches to technology financial products. The results show that new forms of interaction have appeared between banks and fintech companies for adapting to the need for digitalization. These relationships are affected by challenges raised in these technologies such as regulation or customer privacy breach and are also affected by the presence of other big technological financial players. The findings of this study support the need to modernize the traditional financial institutions for facing the international disruption in the financial paradigm caused by FinTech.
