Digital financial services are transforming the way we bank, borrow, save, invest, and make payments. But are these innovations creating more competitive markets, or are they simply fostering new forms of market power? On this episode of Our Curious Amalgam, we speak with Beatriz Marques of the OECD Competition Division about the evolving competitive landscape in digital finance. We explore the role of FinTechs, incumbent banks, card networks, and BigTech platforms; the importance of data, interoperability, and open banking; and what competition authorities can do to foster innovation while protecting competition and consumers in an increasingly digital financial ecosystem.
