Big Box Banks, meaning those that compete largely on price and offer commodity products to mass-market customers.
Notably, big box banks can operate with a range of agility levels. As with the second category, these can also be existing banks (e.g., one of the top four players in the current market) or new entrants (such as a large retailer). In both cases, they will have the benefit of immediate market share and low pricing across a range of products, making them appealing to existing customers.
