When a European bank evaluates its regulatory reporting stack, the question is rarely framed as a strategic architecture decision. It tends to arrive as a procurement line item: "We already use Platform X for core banking — can we activate the reporting module?" The answer is almost always yes. The better question is whether that convenience translates into a defensible compliance posture under the European Banking Authority's current taxonomy cadence, ECB reporting demands, and the expanding scope of frameworks like DORA and CRD VI.
This article makes the case that specialist XBRL software — purpose-built for the taxonomy-heavy, validation-intensive reality of European prudential reporting — consistently outperforms the regulatory reporting modules embedded in core banking platforms, ERPs, and integrated risk suites. The argument is not that integrated platforms are bad software. It is that regulatory reporting is a sufficiently specialised domain that the trade-offs of a module architecture consistently land in the wrong place for compliance-critical institutions.
