Careful with that webinar, I've found it's more of an advertisement for the Verafin product than an actual presentation about combining your Fraud and AML Departments.
For what it's worth, I've worked in multiple institutions that combined Fraud and AML to different degrees. One of them was a larger bank, which had separate departments but shared the same case management system - which provided a good channel for exchanging information. Logistically, it didn't make sense for them to completely combine. Having worked at both sides of the fence in that bank, I'd say there was a mindset difference between the two groups. Fraud/loss prevention seemed to be fast-paced, black-and-white, and quantifiable. AML was more methodical, qualitative, and focused on subjecive, "gray" areas. From a detection system perspective, the only time they seemed to cross paths was with kiting, which would get flagged for layering rules and check fraud rules in separate programs. Therefore, they were better off separated since they could hire personnel focused on their respective areas.
At my current institution, there's a higher degree of workload sharing; both as a matter of resources and taking advantage of the similarities each function has. We're a smaller bank, so justifying expenses can be difficult and everyone's used to wearing multiple hats. In my opinion, the whole "FRAML" thing works better at smaller institutions.
To get started, take stock of the functions and resources within each department and see if and where it would make sense to combine. If you don't have AML or fraud software, Verafin might actually be an attractive option (not an advertisement) because of the resource savings and efficiencies it provides by including both functions in one system.
