IAS 30
Withdrawn
Disclosures in the Financial Statements of Banks and Similar Financial Institutions
Provided disclosure requirements specific to banks and similar financial institutions, including maturity analyses, concentrations of risk, and the hidden reserves prohibition. Superseded by IFRS 7 Financial Instruments: Disclosures.
Withdrawn Standard
IAS 30 (issued 1990) provided disclosure requirements specific to banks and similar financial institutions, including maturity analyses, concentrations of risk, and the hidden reserves prohibition. It was superseded by IFRS 7 Financial Instruments: Disclosures (2007), which extended similar (and in many respects more rigorous) disclosure principles to all entities holding financial instruments, not just banks specifically.
It is retained here for historical reference. For current financial instrument disclosure requirements, always apply IFRS 7.

Conceptual Framework Linkage
Why banks needed industry-specific disclosure guidance
Banks and similar institutions face risk profiles (liquidity, concentration, credit) that are both more pronounced and structurally different from ordinary commercial entities – a bank's core business is managing financial risk. The Conceptual Framework's relevance objective demanded disclosure requirements tailored to this reality, which IAS 30 provided as a dedicated, industry-specific disclosure standard.
HOW IAS 30 MAPPED TO THE FRAMEWORK
Relevance – maturity and concentration disclosures gave users insight into a bank's genuine liquidity and credit risk exposure, which ordinary financial statements alone would not adequately convey Faithful representation – the explicit prohibition on "hidden reserves" (undisclosed provisions used to smooth reported profit) directly enforced transparent, faithful reporting of a bank's true financial position Industry-specific vs universal disclosure – IAS 30's bank-specific scope reflected an earlier standard-setting philosophy of addressing certain risks through dedicated, industry-focused standards, rather than universal principles applicable to all entities
IAS 30's eventual replacement by the universally applicable IFRS 7 (covering all entities' financial instrument disclosures, not just banks) reflects the IASB's later preference for broadly applicable, principles-based standards over narrow industry carve-outs – a recurring pattern across many withdrawn standards in this library.
Key disclosure areas IAS 30 pioneered
Disclosure areaPurpose
Maturity analysisLiquidity risk transparency
Concentrations of riskCredit/geographic/industry risk transparency
Hidden reserves prohibitionPreventing profit-smoothing via undisclosed provisions
These three disclosure pillars are direct ancestors of IFRS 7's liquidity risk maturity analysis, credit risk concentration disclosure, and general transparency requirements – applied today to all entities, not just banks.
2
Scope & Applicability (Historical)
What IAS 30 covered
IAS 30 applied to the financial statements of banks and similar financial institutions (including some other institutions accepting deposits and dealing in money and monetary instruments) – a narrowly targeted, industry-specific scope.
This narrow, industry-specific scope is the key structural difference from IFRS 7, which applies universally regardless of industry.
Key definitions you must know (historical)
Bank (original, broad concept)
An institution whose principal activities include taking deposits and borrowing with the object of lending and investing, and that is included within banking legislation in the jurisdiction of operation.
Hidden reserve
A reserve that understates assets, or overstates liabilities, resulting in an understatement of net assets not apparent from the financial statements.
3
Income Statement Disclosures
Broad categories of interest income/expense and fee income
Banks disclosed major categories of interest and similar income, interest expense and similar charges, and fee/commission income and expense – providing users with a clear picture of the fundamental sources of a bank's core operating revenue, distinct from ordinary commercial entities' revenue disclosure conventions.
4
Maturity Analysis of Assets and Liabilities (with worked example)
The direct ancestor of IFRS 7's liquidity risk disclosure
Banks disclosed an analysis of assets and liabilities into relevant maturity groupings, based on the remaining period to the contractual maturity date – providing users with insight into a bank's liquidity position (whether assets and liabilities' maturities were reasonably matched).
Example 1: A simplified maturity grouping disclosure
A bank discloses loans and advances of $500,000,000 maturing within 1 year, and customer deposits of $650,000,000 also maturing (or repayable on demand) within 1 year.
This disclosure reveals a potential liquidity mismatch – deposits repayable within a year exceed loans maturing in the same period by $150,000,000, meaning the bank must either roll over deposits or source alternative funding to meet obligations – precisely the kind of insight IAS 30's maturity analysis was designed to surface, and the direct conceptual ancestor of IFRS 7's own liquidity risk maturity analysis requirement today.
5
Concentrations of Assets, Liabilities, and Off-Balance-Sheet Items
Surfacing concentrated risk exposures
Banks disclosed significant concentrations of assets, liabilities, and off-balance-sheet items – by geographical area, customer/industry group, or other risk concentration – helping users understand where a bank's risk was disproportionately exposed to a single counterparty, sector, or region, a direct forerunner of IFRS 7's own credit risk concentration disclosure requirement.
6
The Hidden Reserves Prohibition (with worked example)
A uniquely bank-focused transparency safeguard
IAS 30 explicitly prohibited the historical banking practice of maintaining "hidden reserves" – undisclosed reserves used to smooth reported profit across periods by understating assets or overstating provisions in good years, then releasing them in bad years, without transparent disclosure. Banks were required to disclose the aggregate amount of any general banking risk provisions, and movements in them, preventing this opaque practice.
Example 2: Hidden reserve manipulation IAS 30 prohibited
In a historically strong profit year, a bank sets aside an excessive, undisclosed general provision of $50,000,000 (beyond what specific credit risk actually warrants), intending to release it quietly in a future weaker year to smooth reported earnings.
IAS 30 required disclosure of the aggregate amount of such general provisions and their movements – preventing this kind of opaque earnings-smoothing practice, since users could see the provision was created and could scrutinise its justification, rather than it remaining hidden within undisclosed reserves.
7
Losses on Loans and Advances
An early ancestor of today's credit risk/ECL disclosures
Banks disclosed the accounting policy for recognising losses on loans/advances, the movement in any provision for losses during the period, and the aggregate amount of the provision at the reporting date – a considerably simpler disclosure regime than IFRS 9's later three-stage expected credit loss model and IFRS 7's detailed staging disclosures, but addressing fundamentally the same underlying user need.
8
Why IAS 30 Was Replaced
Universal application replacing an industry-specific carve-out
As the IASB developed a comprehensive financial instrument disclosure standard (IFRS 7) applicable to all entities – recognising that liquidity, credit, and market risk disclosures were valuable for many types of entities, not just banks – it made sense to withdraw the narrower, bank-specific IAS 30 and fold its principles into the universal IFRS 7, which offers equivalent (and in several respects more rigorous, e.g. sensitivity analysis, fair value hierarchy) disclosure requirements applicable across the entire economy.

Disclosure Summary (Historical)
Required disclosures under IAS 30
Major categories of interest and fee income/expense Maturity analysis of assets and liabilities Significant concentrations of assets, liabilities, and off-balance-sheet items Aggregate amount of general banking risk provisions and movements, prohibiting undisclosed "hidden reserves" Losses on loans/advances – accounting policy, provision movements, and aggregate balance

Critical Judgments & Estimates (Historical)
Where management judgement mattered most
SIGNIFICANT JUDGEMENTS
Identifying significant concentrations warranting separate disclosure Determining appropriate maturity groupings for the analysis
SIGNIFICANT ESTIMATES
Provisions for losses on loans/advances General banking risk provision amounts, subject to the transparency requirement
Prior to IAS 30's "hidden reserves" prohibition, historical banking practice in some jurisdictions permitted genuinely opaque profit smoothing – a practice this standard was specifically designed to eliminate through mandatory transparency.

IAS 30 vs Modern IFRS 7
Comparison – IAS 30 (1990) vs current IFRS 7
FeatureIAS 30 (withdrawn)Current (IFRS 7)
Applicable entitiesBanks and similar financial institutions onlyAll entities holding financial instruments, regardless of industry
Maturity analysisContractual maturity groupings for assets/liabilitiesUndiscounted contractual cash flow maturity analysis for financial liabilities specifically, more precisely defined
Concentration disclosureGeographic/customer/industry concentrationsSimilar credit risk concentration disclosure, now framed within a broader risk management disclosure framework
Sensitivity analysis / fair value hierarchyNot addressedMandatory market risk sensitivity analysis and three-level fair value hierarchy disclosure
IFRS 7 represents a significant expansion beyond IAS 30's bank-specific content – extending similar principles universally, while also adding entirely new disclosure dimensions (sensitivity analysis, fair value hierarchy) that IAS 30 never contemplated.
