A new study shows California's largest banks aren't spending much with minority-owned businesses.  

Released today by the San Francisco-based Greenlining Institute, the study shows that in a state where people of color make up 60 percent of the population, banks get less than 8 percent of their goods and services from businesses owned by African Americans, Latinos, Asians or Native Americans.  

The banks in the report spent more than $51 billion on goods and services in 2012.
