The Basel Committee on Banking Supervision approved two standards at its 28-29 September 2026 meeting in Indonesia and lined up a string of publications for October, November and year-end. The Financial Services Agency posted a Japanese-language summary and provisional translation of the committee's press release on 6 October. Basel decisions are not automatically binding Japanese law; they are international standards that national authorities then choose how to implement.
Approved at the meeting
The committee approved the 2025 year-end assessment results for global systemically important banks (G-SIBs). The results go to the Financial Stability Board, which is to publish its 2026 G-SIB list at a later date.
It also approved a revision to the G-SIB assessment framework to curb window-dressing, following an earlier consultation. The committee said window-dressing by banks undermines the intended purpose of its standards and risks disrupting financial market operations. The revision is due to be published this month, October 2026.
The third approval is a final standard on machine-readable Pillar 3 disclosures, again following a consultation. The committee said most banks currently disclose only in PDF format, which makes aggregating, processing and comparing data across banks difficult. The final standard is expected around year-end.
What is coming next
| Item | Status | Expected timing |
|---|---|---|
| G-SIB assessment window-dressing revision | Approved | This month (October 2026) |
| G-SIB methodology consultation (European banking union exposures) | Agreed to publish proposal | This month (October 2026) |
| Leverage-ratio review reports (Australia, Canada, Japan, Korea, Switzerland, UK) | Approved | This month (October 2026) |
| Anti-money-laundering risk assessment survey summary | Results summary to be published | This month (October 2026) |
| IRRBB additional Pillar 2 guidance consultation | Agreed to consult | Next month (November 2026) |
| Machine-readable Pillar 3 final standard | Approved | Around year-end |
| Crypto-asset prudential standards review update | Review under way | By year-end |
| Liquidity risk principles revision update | Under consideration | This year |
The committee also agreed to publish a proposed revision to the G-SIB methodology, seeking views on whether to build the treatment of cross-border exposures within the European banking union into the framework. That consultation document is also due this month.
On interest-rate risk in the banking book, the committee said an empirical assessment of its 2016 standard found room for concrete improvement in how banks manage the risk. It agreed to consult on additional Pillar 2 guidance for banks and supervisors, with the consultation paper due next month, November 2026.
The Japan item is narrower. Under its Regulatory Consistency Assessment Programme, the committee approved jurisdictional reports on implementation of the leverage ratio in Australia, Canada, Japan, Korea, Switzerland and the United Kingdom, all due this month. The release gives no findings.
Items still at the review stage
The committee is reviewing targeted elements of its prudential standards for banks' crypto-asset exposures and plans to present an update by year-end. It is also considering targeted revisions to its 2008 principles for sound liquidity risk management, with an update due this year. Both are reviews, not adopted changes.
The committee further agreed to review whether the existing loss-event-type categories in the operational risk framework remain adequate, with a focus on cyber risk and artificial intelligence. A summary of a survey on anti-money-laundering risk assessment covering 19 jurisdictions is due this month.
