> Almost all of this seems untrue (except maybe the last one). I’ve worked at a variety of banks from front to back office across securities and private wealth. I’ve seen plenty of company-specific languages, plenty of C++, Java, perl, python but have literally never encountered a COBOL system.
Two of Australia's four biggest banks – ANZ and Westpac – have historically run CSC Hogan. I don't know what they are doing as of today, but according to media reports ANZ was still using it in 2016 [0] and Westpac in 2019 [1]. Hogan is based on z/OS, CICS, COBOL. Not only is the vendor-supplied product code in COBOL, any customer ends up having to write lots of their own COBOL code to add customisations necessary for their environment. CSC – now DXC – has a replacement platform, Celiriti, which runs on a more mainstream tech stack (Java/Linux/etc), and I believe both were looking at migrating to that eventually. Australia's 6th largest bank, Suncorp, uses Hogan too, having in 2020 abandoned an attempt to replace it with Oracle Banking Platform. [3]
