Czech National Bank (CNB): regulatory returns

What this page covers

Every periodic return the Czech National Bank lists for the main populations it supervises: 99 returns, of which 24 are EU-harmonised (group names end '(EU, EBA)' or '(EU, ESMA)') and 75 are national (the Bank's own; group names end '(national)'). For EU returns this file records only the Czech facts (who files, the Bank's national codes and deadlines where it sets them, and the filing route); the templates and EU validation rules are in the library's EBA entries, or described from ESMA's own material where no EBA or EIOPA entry matches (the CNB gives several ESMA-defined EU returns its own national codes, for example the AIFMD report as OFZ (ČNB) 33-04/35-04 and the instant-payments charges report as sepa_ipr). Banks and credit unions: anchored on the Bank's 'Information duties of financial market entities' page, the credit institutions supervisory-statistics methodology page (which lists the SDAT reporting frameworks EBA_COREP, EBA_FINREP, EBA_FP, EBA_IRRBB, EBA_PAY and the national BANKY and DZ frameworks), and Decree No. 346/2013 Coll. (banks and branches of foreign banks) and Decree No. 426/2013 Coll. (credit unions), each read in full for its own national returns and their content annexes. This gives 11 EU returns (COREP own funds, leverage, large exposures, LCR, NSFR and FRTB, FINREP, asset encumbrance, funding plans, IRRBB and the instant-payments charges report) and 27 national returns for banks, plus 8 further national returns specific to credit unions (which share the same EU returns). Insurers and reinsurers: anchored on the insurers' supervisory-statistics methodology page (SDAT frameworks EIOPA_S2, EIOPA_PEPP and POJIŠTOVNICTVÍ) and Decree No. 305/2016 Coll., giving 7 EU returns (quarterly and annual Solvency II QRTs for solo insurers and groups, the ECB statistics add-on, and the SFCR/RSR disclosure return) and 11 national returns (balance sheet, profit and loss, organisational structure, supplementary statistics, notional minimum capital requirement, intermediary activity, intra-group operations, the motor-insurance guarantee fund return, EEA branch indicators, motor-liability annuities, and the policyholders-offering-insurance return). Investment firms, trading venues and crypto-asset service providers: anchored on the capital markets supervisory-statistics methodology page (SDAT frameworks KT, MKT and the relevant EBA frameworks) and Decree No. 424/2017 Coll., giving 2 EU returns (the IFR prudential reports for Class 2 and Class 3 firms) and 1 further EU (ESMA) return (MiFIR transaction reporting, under the CNB's own TRAFIM/REFFIM codes), 8 national returns (daily transaction, order and settlement reports, the monthly client-assets summary, the quarterly financial position report for venue operators, organisational structure, consolidated group structure and mixed-holding intra-group transactions) and 4 further national returns for crypto-asset service providers under the Markets in Crypto-Assets Regulation (MiCA). Funds and fund managers: anchored on the funds supervisory-statistics methodology page (SDAT frameworks FONDY and FONDY_DOKUMENTY) and Decree No. 267/2020 Coll., giving 2 further EU (ESMA) returns (the money market fund quarterly return under the Money Market Funds Regulation, and the AIFMD report for above-threshold managers, under the CNB's own codes) and 9 national returns (balance sheet and profit or loss, securities issued, investment-instrument structure and asset composition, real-estate fund data, summary information, compliance with operating conditions, the qualified-investor fund report, the key-information report, and the below-threshold manager's AIFMD-style report). Payment and e-money institutions: anchored on Decree No. 401/2021 Coll., giving 2 national returns (quarterly payment statistics, and the half-yearly payment statistics and fraud report); these firms, and banks and credit unions, also file the EU instant-payments charges return above. Pension management companies: anchored on Decree No. 425/2012 Coll., giving 6 national returns (balance sheet and profit or loss, the retirement/pension unit report, organisational structure, funds received and paid out, capital and capital requirements, and portfolio composition); the Czech supplementary pension savings and transformed-fund system is a national scheme, not an EU-harmonised occupational pension (IORP) regime, so no EU return applies. Cross-sector: the DORA register of information on ICT third-party arrangements is recorded once, for all sectors, as an EU return. Left out: statistical returns collected for monetary, balance-of-payments and payment-statistics purposes under Decree No. 235/2013 Coll. and Decree No. 314/2013 Coll. (a separate 'Legislativa k výkaznictví' page keeps these apart from supervisory reporting); the Central Credit Register and Central Register of Accounts (databases built from submissions, not periodic returns in the sense covered here); DORA major ICT incident reports and significant-cyber-threat notifications (event-driven, not periodic); the EBA's MiCA token-issuer reporting (sent directly to the EBA, not through the CNB, and no Czech issuer confirmed); regular reporting by issuers of listed securities and the related 'ECP' SDAT framework (listed-issuer disclosure, not supervision of a regulated financial firm); bureaux de change, retail intermediaries and other smaller populations the CNB's pages list, which were not reached in this session; and ad hoc or event-driven notifications, licensing applications and fit-and-proper filings generally. Resolution planning, MREL/TLAC, G-SII and financial-conglomerate EU returns that may apply to some Czech banks are also left out: no specific CNB page or document confirming them was read in this session (see gaps).

How firms file

• SDAT (Sběr dat ČNB)

  The Czech National Bank's data-collection system: a web application and web-service interface through which banks, credit unions, insurers, pension management companies, investment firms, funds, fund managers, payment and e-money institutions and crypto-asset service providers file their statistical and supervisory returns, both EU-harmonised (COREP, FINREP, Solvency II QRTs and others) and the CNB's own national returns. Firms must register and sign returns with a qualified electronic certificate. Source

Reuse terms for the CNB's documents

Czech National Bank: Terms and conditions of using the internet pages of the Czech National Bank, section 3 (Rights of the website users), checked 13 November 2026. In the CNB's words:

You may store, distribute and reproduce all our Internet information with the exception of texts with an author, i.e. texts whose author is given in the header or footer (in such cases, you must obtain the author’s consent directly from her/him or via the Czech National Bank), and images whose copyright is clearly not owned by the CNB. You may create links to the CNB website, including deep linking, from other websites but note that the CNB reserves the right to change the content and internal structure of the website and that the URLs of individual CNB web pages may not be the same in all circumstances. The CNB must always be stated as the source of the information (Source: the CNB), the file and its content may not be altered in any manner and each page must be displayed in a new browser window. If an extract from a text, a text divided into several sections or a combination of multiple texts is used, the facts and meaning of the text may not be changed.

Can others share copies?

Allowed with conditions.

Conditions

State the CNB as the source ("Source: the CNB"). Do not alter a file or its content. Display each CNB page in a new browser window. Extracts and combinations must not change the facts or meaning. Texts with a named author, and images whose copyright the CNB does not own, need their owner's consent.

What the library does

Keeps copies of the documents, as the terms allow. The CNB's terms let anyone store, distribute and reproduce its internet information, unchanged and with the CNB stated as the source, and allow deep links. So copies of the CNB's own reporting documents are kept, unchanged, with that credit. Legal texts, texts with a named author and other bodies' material are not copied.

Notice the CNB's terms ask for: Source: the CNB (Czech National Bank, https://www.cnb.cz). Documents copied here are unchanged. The plain-English summaries are Line4's own; the CNB does not endorse this library.

What could not be verified

Said plainly, so nobody relies on a fact the sources do not give.

• Not checked: the SDAT public metadata pages (sdat.cnb.cz/.../F2001-prehled-vykazu.zul and similar 'presentation of methodology' links) render through JavaScript; page.py received only a 'Pracuji...' placeholder, so the per-return field lists and remittance-date calendars those pages would show could not be read.
• Not checked: e-sbirka.gov.cz and e-sbirka.cz (the Czech official legal-text portal) serve a JavaScript single-page application; every path requested, including robots.txt, returned the same short HTML shell, so decree and act texts could not be read there. They are cited in legal_basis by title only, the same way EUR-Lex links are used elsewhere in this library, and were not requested for facts.
• OFZ (ČNB) 15-01 is listed among the DOFOS series of the Fondy framework on the funds supervisory-statistics page, but is not named in Decree No. 267/2020 Coll. as read in this session; not described as a separate return here.
• Frequencies and deadlines for the four crypto-asset service provider (CASP) national returns (CSPCZ01, CSPCZ02, CSPCZ10, CSPCZ11) were not found on the pages checked; the CNB's page states only that they are collected under the KT (Kapitálové trhy I) framework in SDAT. No decree setting their content was identified.
• POJ (ČNB) 90-01 (annuities from motor third-party liability insurance) and POJ (ČNB) 26-04 (policyholders offering the chance to become insured): the decree text read does not separately state a filing deadline beyond the return's frequency.
• Not checked: whether a later amendment to Decree No. 424/2017 Coll. (investment firms reporting) has updated its references from the Capital Requirements Regulation to the EU Investment Firms Regulation (IFR); the CNB's capital markets methodology page confirms an EBA_IF framework operates in SDAT, which points to the IFR applying in practice.
• Not checked: whether the fraud data in the national half-yearly return PSS (ČNB) 22-02 (Decree No. 401/2021 Coll.) has since moved into the EBA_PAY harmonised framework in SDAT, which the credit institutions methodology page lists alongside COREP, FINREP and other EBA frameworks, or whether the two run in parallel.
• EBA resolution planning reports (resol1, resol2), MREL/TLAC reporting (mrel-tlac), G-SII indicators (gsii) and financial conglomerates intra-group reporting (fc) were not confirmed with a specific CNB page or document read in this session; left out of this file rather than guessed, even though the CNB's resolution function and the Resolution section of the legislation pages suggest some of them apply to Czech banks.
• The EIOPA_PEPP framework is named as a SDAT reporting framework on the insurance methodology page, but no Czech PEPP (pan-European personal pension product) provider was confirmed on the pages checked; not described as a return here.
• The CNB's Central Credit Register (Decree No. 131/2018 Coll.) and Central Register of Accounts (Decree No. 300/2016 Coll. and Decree No. 30/2017 Coll.) were not examined in depth; they are registers/databases built from bank submissions rather than a periodic supervisory return in the sense covered here, and are left out of scope, consistent with how other national authorities' credit registers and account registers are treated elsewhere in this library.
• The EBA's MiCA reporting for issuers of asset-referenced tokens and e-money tokens (library ids mica, mica-of) is sent directly to the EBA rather than through the CNB, as the CNB's own credit institutions methodology page states; no Czech issuer of such tokens was confirmed on the pages checked, so this is left out of scope rather than included as a CNB-collected return.
• No day-by-day remittance-date schedule equivalent to some other national authorities' published reporting calendars was found on the CNB's pages for COREP, FINREP, asset encumbrance, funding plans or IRRBB; these EU returns' deadline fields record that the EU implementing technical standard sets the dates, without a CNB-specific calendar to cite.
• Decree No. 425/2012 Coll. (pension management company reporting): the copy read does not itself state that it has been amended, unlike the other national decrees used in this file, although the CNB's laws page separately lists Decree No. 404/2020 Coll. and Decree No. 476/2017 Coll. as having changed it, and the file served carries a 2020 modification date consistent with that.
• Regular reporting by issuers of listed securities (half-year and annual financial reports under the Transparency framework) and the CNB's 'ECP' (Emitenti cenných papírů) reporting framework seen in the SDAT news feed were not examined; left out as a different regime (listed-issuer disclosure, not prudential or conduct supervision of a regulated financial firm).
