04 · RisKIT · Prudential models
RisKIT is a suite of 22 pre-built prudential risk models in native Excel, made by RiskTAE for regulated financial firms that need regulator-aligned capital and liquidity numbers without a bespoke build or a software subscription. Each model is bought once under a perpetual licence for your firm, and every formula is open to review.
Who it is for
The models are for risk, finance and treasury teams at banks, building societies, investment firms and payment institutions who carry the accountability for the numbers.
They have neither months nor a large budget for a custom build, so the design brief was a Toyota Corolla, not a Ferrari: something proportionate that your own team can keep running.
Behind the models is a team. We configure them to your balance sheet, train the people who will run them and support you wherever you operate, so you buy a working capability rather than a file.
Why RisKIT
Most firms get a prudential model one of three ways, and each has a cost that shows up later. RisKIT is a fourth route: a finished model that your firm owns outright.
| Route | What it usually costs you | Who owns the logic | How you pay |
|---|---|---|---|
| Build it in-house | Slow, competes with day-to-day work and depends on the few people who built it; documentation is usually the first thing to slip | You, while those people stay | Staff time |
| Hire consultants | A blank-page build: the scope grows, delivery takes months and the model is hard to run without them | You, once the handover works | Project fees |
| Buy software | Limited tailoring, heavier data work than expected and logic your reviewers cannot see; leaving is painful | The vendor | Annual fees that tend to rise |
| RisKIT | A finished model built to the rules, configured to your balance sheet in weeks and tailored further by your own team | You, from day one | One price, once |
The suite
Each model has a reference number, and each framework comes in the versions a firm actually needs, with or without market risk.
| Framework | Models | Numbers |
|---|---|---|
| UK Basel 3.1 (PRA) | All risks excluding FRTB market risk; all risks including FRTB market risk; FRTB market risk only | 500, 501, 502 |
| EU CRR III and CRD VI | The same three versions | 600, 601, 602 |
| Basel IV (the finalised Basel III standards, for other jurisdictions) | The same three versions | 700, 701, 702 |
| US Basel III Endgame | The same three versions | 800, 801, 802 |
| Basel III liquidity | Liquidity and funding (ILAAP); Basel II and III hybrid | 400, 401 |
| Basel II and Basel 2.5 | All risks with or without Basel 2.5 market risk; Basel 2.5 market risk only | 200, 201, 300 |
| Basel I | Credit risk (1988); 1996 market risk amendment | 100, 101 |
| Recovery and resolution | Recovery and resolution planning tool | 900 |
| Payments and e-money (EU PSD3 and PSR; UK) | Capital and wind-down tool for payment and e-money institutions, EU and UK versions | 1000, 1100 |
Earlier Basel versions are there because many national regulators still apply them. If your framework is a mix, we build a hybrid.

Capital models
The all-risks capital models calculate Pillar 1 requirements under the standardised approaches of their framework. In the Basel 3.1, CRR III, Basel IV and US versions that means credit, counterparty credit, credit valuation adjustment and operational risk, with FRTB market risk in the versions that include it. The models hold capital resources, the capital conservation and countercyclical buffers, Pillar 2A, management buffer overlays and the leverage ratio.
Pillar 2 covers interest rate risk in the banking book, concentration risk, and liquidity, reputational, environmental and social and cyber risk capital. The Basel 3.1 versions add group, strategic, legal and model risk.
Each model runs a base case and four stress scenarios (idiosyncratic, market-wide, combined and macroeconomic) over a three-year horizon, supports reverse stress testing, and produces board-ready outputs: capital ratio trends, risk-weighted asset breakdowns, surplus or deficit charts and the Pillar 3 disclosure report.
Assumptions sit in one register with a change log, so internal audit can follow every number back to its source, and traffic-light triggers show a ratio heading for its threshold before it gets there.
Liquidity model
Model 400 calculates the liquidity coverage ratio, the net stable funding ratio and the survival period, with liquidity gap analysis in local and foreign currency across maturity buckets from overnight to five years.
It runs business as usual plus mild, moderate and severe stress over three years, sizes the contingency funding needed to close any gap, and supports reverse stress testing. Behavioural assumptions, such as how retail deposits really behave, are set in one place and can be changed.
Recovery and resolution
Model 900 gives a bank one place to build and run its recovery plan: the triggers and thresholds, the recovery options and what each is worth, the early warning indicators and the governance around them. It also maps creditors and critical services for resolution planning, and tracks remediation actions until they close.
For banks and building societies outside the systemic tier, the tool supports solvent exit planning: the solvent exit analysis the PRA expects as part of normal business, and the execution plan a firm needs once an exit becomes a reasonable prospect.

Payments and e-money
Yes. Models 1000 and 1100 are a capital and wind-down tool for payment institutions and e-money institutions. They project own funds and liquidity 12 to 18 months ahead under base and stressed conditions, test the effect of volume shocks, margin compression, fraud losses and outages, track safeguarding and reconciliations, and set out the wind-down plan with its triggers, owners and timelines.
Model 1000 follows the EU’s new payments rules, PSD3 and the Payment Services Regulation, which the Council and the European Parliament agreed on 27 November 2025; they will require a winding-up plan from every applicant. Model 1100 is for UK firms. The UK is not adopting PSD3, and the FCA’s changes to safeguarding have applied since 7 May 2026, so talk to us about how the tool fits the rules you report under.

Why Excel
Because many regulated firms already do their prudential modelling in Excel, and it is where your reviewers can see everything. Every formula is visible, and input and output cells are colour-coded separately. The models contain no VBA or macro code, which removes a route for malicious code and leaves your security team nothing to vet.
The models take data from your own finance and treasury reporting, and there is no platform to renew or exit.
Implementation
Our team does, wherever you operate. Implementation starts with a walkthrough of the model against your balance sheet, then configuration, a first run with your own data and training for the people who will own it.
After go-live you have remote support for set-up, data entry and early use, and Risk Advisory can add validation, tailoring or a full ICAAP or ILAAP built on the model.
Licence
You pay once. The licence is perpetual, for internal use by the legal entity named in your order, with no subscription or annual maintenance fee. Each model comes with a user manual and remote support for set-up, data entry and early use.
If a regulatory logic error or a functional defect turns up in the model as delivered, we correct it free of charge, however long after delivery it is found. A regulatory update commitment also covers statutory changes to the rules your model is built on, for the update period set in your order.
Tailoring, implementation and validation support are available from Risk Advisory as a separate piece of work. Prices are available on request.
Basel 3.1
Models 500 to 502
Models 500 to 502 implement the PRA’s Basel 3.1 rules, which apply from 1 January 2027 under policy statement PS1/26, published on 20 January 2026. Models 501 and 502 use the new standardised approach for market risk under the Fundamental Review of the Trading Book. The internal model approach for market risk, which applies from 1 January 2028, is outside their scope.

FAQ
No. RisKIT models are Excel files that you keep and run on your own systems. There is no login or subscription, and your data never leaves your firm.
You are, as with any model your firm uses. It goes into your model inventory and through your usual governance, and because every formula is open, your validators and auditors can test it without asking us.
Yes. The models are standardised but configurable, and your team can tailor them. Keep an unmodified master copy, so that any error you report can be checked against the model as delivered.
Firms typically move from walkthrough to implementation in weeks rather than months. If your team is short of time, we can support the set-up.
The regulatory update commitment covers statutory changes to the standards your model is built on, for the update period in your order. Larger rebuilds, new modules or a move to a different framework are quoted separately.
Each model has a one-off price, with no subscription or annual fee. Prices are available on request.
