  In the past decade, the financial industry has experienced a technology
revolution. While we witness a rapid introduction of conversational bots for
financial services, there is a lack of understanding of conversational user
interfaces (CUI) features in this domain. The finance industry also deals with
highly sensitive information and monetary transactions, presenting a challenge
for developers and financial providers. Through a study on how to design
text-based conversational financial interfaces with N=410 participants, we
outline user requirements of trustworthy CUI design for financial bots. We
posit that, in the context of Finance, bot privacy and security assurances
outweigh conversational capability and postulate implications of these
findings. This work acts as a resource on how to design trustworthy FinBots and
demonstrates how automated financial advisors can be transformed into trusted
everyday devices, capable of supporting users' daily financial activities.
