Skill: Convert supervised-entity data into an MNB supervisory report

Region: Hungary (Magyarország) Category: Government — Regulatory Does: Takes a supervised entity's prudential/operational data (balances, exposures, transactions, statistics) and assembles the statement-specific supervisory report as structured XML or XBRL for electronic filing to the MNB (Magyar Nemzeti Bank) through its supervisory reporting channel (ERA / electronic reporting system) — declaring the institution, the reporting period, the statement (table) code, and its data cells per the relevant MNB reporting decree.

Spec: MNB — supervisory reporting decree / taxonomy (statement- and version-specific XML/XBRL)

The MNB, as Hungary's central bank and integrated financial supervisor, collects mandatory supervisory and statistical reports from banks, insurers, funds, investment firms, and other supervised entities. Each report is defined by an MNB decree (MNB rendelet) and a statement (tábla) code, with a reporting frequency (daily, monthly, quarterly, annual) and a prescribed structured format — entity-specific national templates in XML, plus XBRL taxonomies for the EU harmonised packages (e.g. COREP/FINREP, Solvency II) MNB ingests. Element/table names below follow the specific MNB statement, not a single verbatim XSD; the decrees and taxonomies are versioned, so confirm the current release for your reporting population.

When this applies

A supervised entity (credit institution, insurer, fund manager, investment firm, payment institution, etc.) must submit a periodic supervisory/statistical report to MNB.
The frequency and deadline are set per statement by the applicable MNB decree (e.g. monthly by a set business day, quarterly within the prescribed window).
The package is national XML (MNB template) or XBRL (harmonised EU reporting that MNB collects), submitted via the MNB electronic reporting system (ERA / Kibővített Elektronikus Rendszer az Igazgatási Adatok fogadására) under the entity's credentials.

Structure (supervisory statement → XML/XBRL)

header        institution id (MNB-issued törzsszám / intézményi azonosító), name,
              reporting reference date / period, statement (tábla) code, decree & taxonomy version
context       reporting entity, period, currency, consolidation scope (XBRL contexts/dimensions)
data          statement cells: balances, exposures, P&L, statistical aggregates keyed by
              the statement's row/column codes (XML) or taxonomy concepts (XBRL facts)
crosschecks   intra- and inter-statement validations defined by the taxonomy/decree

Data rules

Institution identified by its MNB register id (törzsszám / intézményi azonosító); the statement code and version must match the population and the in-force decree.
Cells keyed to the statement's row/column codes (national XML) or to taxonomy concepts with contexts/dimensions (XBRL) — currency, period, and consolidation scope must be set correctly; do not free-form fields.
Validation rules (EBA/MNB) must pass: intra-table sums, inter-table reconciliations, and sign conventions are enforced; failures block acceptance.
Currency and units per the statement (HUF, or original currency with HUF conversion where required); follow the decree's rounding (often HUF thousands or millions).
Corrections / resubmissions reference the same reporting period and statement; late or missing filings carry supervisory consequences.

Worked example (outline)

header:  intézményi azonosító=<MNB id>, statement=<tábla kód>, refDate=2026-03-31, taxonomy=<current>
context: entity=<id>, period=2026-Q1, currency=HUF, scope=solo
data:    total assets=850,000 (mFt), of which loans=600,000 (mFt), CET1=70,000 (mFt)
check:   total assets = Σ asset rows  ✓ ; cross-statement tie to capital report  ✓

Generated as MNB XML / XBRL, run through the validation rules, then submitted via the MNB electronic reporting system for the period.

Validation checklist

Correct statement (tábla) code and current decree/taxonomy version for the reporting population
Institution MNB id (törzsszám / azonosító) and reporting period/reference date correct
Cells keyed to row/column codes (XML) or taxonomy concepts with contexts/dimensions (XBRL)
Currency, units, and consolidation scope set per the statement
Intra- and inter-statement validation rules pass; sign conventions respected
Corrections reference the same period/statement; deadline per the decree met
Rounding (HUF thousands/millions) per the statement convention

Last updated: 2026-06-04 — MNB supervisory statements, decrees, taxonomies, and deadlines are statement- and version-specific; confirm the current schema/version, identifiers, rounding, and deadline against current authority (mnb.hu) guidance before use.
