Sand and sea are hallmarks of Puerto Rico's geography, and Santander BanCorp is a hallmark of the island's economy. The holding company owns Banco Santander Puerto Rico, one of the largest banks in the commonwealth, providing commercial, consumer, and mortgage banking services through more than 100 branches and 150 ATMs, and online. The bank maintains a diversified loan portfolio, comprising residential mortgages and consumer and commercial loans. Santander BanCorp became a wholly owned subsidiary of Grupo Santander in 2010, after the Spanish banking giant bought the shares of the company it didn't already own.
