According to economic theory, repeated interactions can play a crucial role in shaping trust. We randomly allocated people to treatments that promote interactions with bankers. Next, these people play incentivised trust games with their own banker and with an anonymous other banker. While the effect on trust in the own banker is limited, the impact on trust in other bankers is important. We also find account savings strongly associate with trust in one's own banker. Our experiment suggests that trust in one's banker matters for savings, but that it is more difficult to influence than trust in bankers in general.
