The eSLR Reform, Explained: What Changed and Why

Luis Estrada — Mon, 21 Sep 2026 12:01:15 GMT

A leverage ratio is supposed to be a backstop. For several US G-SIB subsidiaries, it had become the binding constraint. TheNovember 2025 final rule, effectiveApril 2026with early adoption from 1 January 2026, recalibrated it, and the way it did so tells you more than the numbers do.

CET1 vs AT1 vs Tier 2: the capital stack, properly explained

Luis Estrada — Thu, 17 Sep 2026 06:00:02 GMT

Not all bank capital is equal, even when it all shows up on the same balance sheet. CET1, AT1, and Tier 2 rank on one key property: how reliably each absorbs losses while the bank keeps running. Get that ranking wrong, and you'll misread every capital ratio you look at afterward, including why a 14% CET1 ratio didn't save Credit Suisse. Here's the stack, properly explained.

Why a 14% CET1 Ratio Didn't Save Credit Suisse

Mirai RiskTech — Thu, 10 Sep 2026 10:01:54 GMT

Credit Suisse entered March 2023 reporting a CET1 ratio of 14.1% and a liquidity coverage ratio near 150%. Both numbers were accurate. Both were published. Within a week, the bank had been merged into UBS over a weekend under Swiss emergency law.

Why Aren't Strong Liquidity Ratios Enough for Banks?

Miguel Angel Penabella — Tue, 08 Sep 2026 10:02:50 GMT

For much of the past decade, liquidity was abundant and readily available at relatively low cost, allowing many banks to focus primarily on meeting regulatory requirements and maintaining comfortable buffers above minimum levels.

That environment is changing as liquidity becomes more costly, funding markets more competitive, customer behavior more dynamic, and balance sheet resources more constrained. This article explores what these changes mean for liquidity management and how banks can build a more anticipatory and integrated approach, supported by better data, behavioral modeling, dynamic scenarios, governance, and decision-making.

EBA's IRRBB Reporting Consultation: What Will Really Change

Mirai RiskTech — Thu, 03 Sep 2026 06:00:01 GMT

In April 2026, the EBA opened a consultation on simplifying IRRBB reporting. Before anyone in finance or risk starts celebrating a lighter workload, it's worth asking what a supervisor who now benchmarks bank models in near-real time is actually willing to give back.

Spoiler: not what you're hoping for.

Why Operating Model Integration Outperforms Cloud Migration Alone

Olmo Vázquez — Mon, 31 Aug 2026 06:00:00 GMT

Cloud migration has transformed the technology landscape of financial institutions over the past decade. Infrastructure has become more scalable, hardware investment cycles have been reduced, and many organizations now benefit from greater flexibility in the way computing resources are deployed. For many institutions, migrating balance sheet management applications to the cloud has become an important milestone within broader technology modernization programs.

As these modernization initiatives mature, a different question begins to emerge. If infrastructure has already been modernized, where does the next layer of value come from?

EVE vs NII: The Two Lenses of Interest Rate Risk

Mirai RiskTech — Thu, 27 Aug 2026 06:00:01 GMT

Every question about interest rate risk in the banking book (IRRBB) can be asked in two ways, and the two answers routinely disagree. Economic value of equity (EVE) asks what the balance sheet is worth if rates move; net interest income (NII) asks what happens to the margin. Understanding why they conflict, and why every modern regulatory framework requires banks to measure both, is the single most important piece of intuition in this field. It is also, as Silicon Valley Bank demonstrated in March 2023, a matter of survival.

SVB's IRRBB Failure: A Case Study in Interest Rate Risk

Mirai RiskTech — Thu, 20 Aug 2026 06:00:00 GMT

Silicon Valley Bank did not fail because it could not measure its interest rate risk. It measured it, breached its own limits, and then changed the assumptions until the numbers behaved. The risk stayed.

March 2023 ended the era in which interest rate risk in the banking book (IRRBB) could be treated as a second-tier risk: real, but rarely fatal. SVB, then the 16th largest US bank, failed in substantial part because of textbook IRRBB, unmanaged. The numbers, assembled from the Federal Reserve’s Barr report and public filings, map onto the discipline’s core concepts almost too neatly. It is a story in three acts.

CP5/26: Central Bank Facilities Enter UK Liquidity Adequacy

Mirai RiskTech — Thu, 13 Aug 2026 05:00:01 GMT

For fifteen years, one principle has sat at the foundation of liquidity regulation: your buffer has to be your own. The central bank is a backstop, deliberately kept outside the ratios, on the logic that a bank must be able to survive a crisis without assuming it will be rescued. In March 2026 the PRA proposed to change that. CP5/26, “Modernising the liquidity policy framework,” would let a bank’s drawing capacity at regular Bank of England facilities count toward its liquidity adequacy. It is the biggest UK liquidity policy event since the framework was built, and if it is adopted, the UK becomes the first major jurisdiction to bring the central bank formally inside the fence.
