Huntington Bank grew its year over year auto portfolio by 39% to $6.9 billion at the end of the first quarter compared to $5 billion the same time last year. Huntington said in its earnings presentation Wednesday that it expects the bank’s indirect auto loan business will grow as originations remain strong. The bank touted its dealer relationships, saying it currently works with 3,500 dealers and is the dominant player in the Midwest. The bank also said it had been using its custom credit scorecards to enhance more predictive modeling.
