Recently, developing countries have witnessed a sharp increase in foreign bank participation. We examine the impact on banking outreach using newly gathered data for Mexico, where foreign bank participation rose from 2% to 83% of assets during 1997–2005. Country-, bank-, and bank-municipality-level estimations show a decline in the number of deposit and loan accounts. While country- and bank-level estimations indicate an increase in the share of municipalities with bank branches and in the likelihood of bank presence, bank-municipality regressions show that only rich and urban municipalities benefited. Overall, the evidence is consistent with a decline in outreach.

The “conventional wisdom” in academic and policy circles argues that, while large and foreign banks are generally not interested in serving SMEs, small and niche banks have an advantage because they can overcome SME opaqueness through relationship lending. This paper shows that there is a gap between this view and what banks actually do. Banks perceive SMEs as a core and strategic business and seem well-positioned to expand their links with SMEs. The intensification of bank involvement with SMEs in various emerging markets is neither led by small or niche banks nor highly dependent on relationship lending. Moreover, it has not been derailed by the 2007–2009 crisis. Rather, all types of banks are catering to SMEs and large, multiple-service banks have a comparative advantage in offering a wide range of products and services on a large scale, through the use of new technologies, business models, and risk management systems.
