FRTB 2027: What Awaits Banks on Market Risk Capital?
The EU has deferred FRTB, the market risk leg of Basel III, to 1 January 2027 and in 2026 adopted transitional adjustments. For banks this is not only a modelling question; it is one of data, boundaries and business model.
The Fundamental Review of the Trading Book (FRTB) is the market risk component of the Basel III reforms. The European Commission deferred the first application date to 1 January 2027 having taken account of implementation timetables in other major jurisdictions and of competitive conditions. In June 2026 targeted transitional adjustments were also adopted; these measures are expected to apply for a defined period from 2027 onwards.
What is FRTB trying to change?
Against the weaknesses in the old market risk framework that the financial crisis exposed, FRTB aims to make risk measurement more sensitive, to reduce arbitrage at the trading book boundary and to treat illiquid risk factors more prudently. The standardised approach becomes more granular, while under the internal model approach desk-level eligibility and comprehensive testing gain importance.
Four critical implementation areas
- The trading and banking book boundary: which book a product sits in, and on what terms transfers can be made, demands clear governance.
- The risk factor data set: the sufficiency, observability and historical quality of market data feed directly into the capital outcome.
- The standardised approach engine: the sensitivities-based method and the default and residual risk components have to be applied correctly.
- Internal model eligibility: desk-level tests, backtesting and P&L attribution results can restrict the use of models.
Why does the capital effect differ from bank to bank?
The FRTB effect depends on portfolio composition. Complex options, less liquid risk factors, concentrated positions or trading desks that lose model eligibility can face materially higher capital consumption. Quoting a single percentage for “how much FRTB raises capital” is therefore misleading.
| Area | Question to ask | Risk |
|---|---|---|
| Product inventory | Which position sits in which book, and why? | Misclassification and a capital surprise |
| Market data | Is historical observation of the risk factors sufficient? | Additional capital arising from NMRF |
| Model | Are the desk tests passed consistently? | A return from internal models to the standardised approach |
| Finance | Is the capital effect reflected in pricing? | Erosion of economic profitability |
The preparation required in 2026
The time remaining before the 2027 implementation should be used to resolve parallel run and data quality problems. Banks need to run a joint programme involving not only the regulatory team but treasury, market risk, finance, IT, data governance and the front office. If the capital effect and the change in RAROC are not measured by product in advance, abrupt adjustments to customer pricing may be needed after go-live.
While FRTB changes the technical method of calculating market risk, it also redefines the capital economics of trading activity. Successful implementation requires more than regulatory compliance: reliable data, consistent product governance and carrying the capital-to-profitability link into management decisions.
