Basel III compliance checklist \u2014 published by FineIT
This Basel III compliance checklist is published by FineIT Private Limited (est. 2001), a quantitative advisor to the International Accounting Standards Board on Predictive Analytics and a member institution of the Basel Committee on Banking Supervision (BCBS). The checklist distils supervisory requirements across capital adequacy, risk-weighted assets, liquidity, leverage, and buffers into a practical sequence for banks implementing or remediating Basel III programmes.
Capital requirements covered include the Common Equity Tier 1 (CET1) minimum of 4.5% of RWA, the Tier 1 minimum of 6.0%, and the Total Capital minimum of 8.0%, plus the Capital Conservation Buffer (2.5%), the Countercyclical Capital Buffer (0–2.5% jurisdiction-dependent), and the Global or Domestic Systemically Important Bank surcharge where applicable. Liquidity requirements cover the Liquidity Coverage Ratio (LCR ≥ 100%) and Net Stable Funding Ratio (NSFR ≥ 100%). The leverage ratio requires Tier 1 capital of at least 3% of total exposures, with higher expectations for G-SIBs.
FineIT Basel Analytics Suite automates these computations with credit, market, and operational RWA engines, stress testing, ICAAP, ILAAP, and regulator-specific submission templates for CBUAE, SBP, SAMA, CBK, NRB, CBB, QCB, BoT, RBF, PRA, OSFI, and more. 200+ Big 4 audit approvals have been logged across FineIT platforms, with a 14-day standard implementation window.

Frequently asked questions
What are the minimum capital requirements under Basel III?
CET1 ratio: 4.5% of risk-weighted assets; Tier 1 ratio: 6.0%; Total Capital ratio: 8.0%. Additional buffers include the 2.5% Capital Conservation Buffer, a jurisdiction-specific Countercyclical Capital Buffer (0–2.5%), and a G-SIB or D-SIB surcharge where applicable.
How often must Basel III ratios be reported?
Capital adequacy ratios are typically reported quarterly. The Liquidity Coverage Ratio (LCR) usually requires daily internal monitoring with monthly supervisory reporting. NSFR is reported quarterly. Leverage ratio reporting is typically quarterly, though some jurisdictions require monthly.
What is the implementation timeline for Basel III?
Full phase-in of Basel III capital components completed by 1 January 2019. Basel III revisions (often called Basel IV) have continued implementation timelines running through 2025–2028 in most major jurisdictions, with revised standardised and IRB approaches to credit risk, operational risk, market risk (FRTB), and output floor.
How are RWA calculated under Basel III?
RWA are calculated separately for credit risk (Standardised or IRB), market risk (Standardised or IMA under FRTB), and operational risk (Standardised Measurement Approach). Totals are aggregated and then multiplied by the minimum capital ratios. The revised standards introduce an output floor of 72.5% of Standardised RWA.
What is ICAAP and how does FineIT support it?
The Internal Capital Adequacy Assessment Process (ICAAP) is a bank’s own view of the capital it needs to support all material risks. FineIT Basel Analytics Suite provides stress-testing, scenario analysis, capital planning, and board-ready ICAAP documentation aligned with BCBS and local supervisory expectations.
Which regulator templates are pre-built in Basel Analytics Suite?
Templates cover CBUAE, SBP, SAMA, CBK, NRB, CBB, QCB, BoT, RBF, UK PRA, and Canadian OSFI. Submission format (regulator returns, XBRL where applicable) and calculation specificity follow each jurisdiction’s guidance.
