EU Basel III Market Risk Adjustments: The FRTB Multiplier for Trading Book Capital

ByOfficer

Last updated: June 2026

If your trading desk capital plan for 2027 already assumes the full Fundamental Review of the Trading Book bites on 1 January, the European Commission just changed the arithmetic. On 4 June 2026 it adopted a delegated act that keeps the new Basel III market risk rules switching on as planned, but bolts a multiplier on top to hold down the capital increase for three years. Read the headline as a delay and you will build the wrong COREP cell, disclose the wrong number, and explain the wrong figure to your supervisor at the next joint supervisory team meeting.

This is a change to how own funds requirements for market risk get calculated, not a change to when the framework applies. The distinction sounds pedantic. It is the whole story. The FRTB still becomes the live capital framework on 1 January 2027. What the Commission has done is reach for the one lever it had left under the Capital Requirements Regulation to soften the impact while major jurisdictions outside the EU drag their feet on the same standard.

Below is what the 4 June 2026 act actually does, where the legal power comes from, why it had to be a multiplier rather than another postponement, and what reporting and disclosure teams should be mapping now. The primary keyword here is straightforward: Basel III market risk is moving from a deferred problem to a live, capitalised, but discounted one.

What the Commission adopted: temporary Basel III market risk relief

The Commission adopted a delegated regulation amending Regulation (EU) No 575/2013 (the CRR) to apply a multiplier that temporarily offsets the capital impact of the FRTB for EU banks. The measure runs for three years from 1 January 2027. It does not move the FRTB application date, which stays at 1 January 2027.

The mechanism is a targeted multiplier applied in the calculation of own funds requirements for market risk. The Commission’s own framing is a multiplier to offset the capital increase that the FRTB would otherwise produce, applied for a period long enough to see whether the rest of the world catches up. The stated reason is competitive: delays in FRTB implementation by other major jurisdictions raised concerns about competitive distortions for EU banks active in trading. The Commission has said other major jurisdictions are expected to delay FRTB by at least a year.

Because this is a delegated act, it is not yet final law on the day of adoption. The European Parliament and the Council have a three-month period to object, extendable by a further three months at their request. If neither institution objects, the measure takes effect in time for the 1 January 2027 application date. That scrutiny window is the reason the operational detail, including the precise scope of the targeted amendments, sits in the delegated act text rather than in the press material, and why a reporting team should treat the headline mechanism as settled but the legal detail as pending Official Journal publication. The multiplier is applied in the calculation of own funds requirements for market risk after the output floor: each adversely affected bank calibrates its own factor so that its post-amendment, post-floor FRTB requirement scales down to its pre-FRTB level. The calibration methodology sits in the delegated act; confirm the detail against the act and its technical-implications Q&A once published.

The legal basis: Article 461a CRR, and why it matters which limb

The power comes from Article 461a of the CRR, inserted in its current form by CRR3, Regulation (EU) 2024/1623. Article 461a(1) tells the Commission to monitor the differences between how the EU and third countries implement international market risk standards, covering both the size of own funds requirements and their date of application. Article 461a(2) then gives the Commission two distinct tools where it observes significant differences.

The first tool, in Article 461a(2)(a), lets the Commission apply targeted operational relief measures or targeted multipliers equal to or greater than 0 and lower than 1 in the calculation of own funds requirements for market risk, for specific risk classes and specific risk factors, using one of the approaches referred to in Article 325(1). The legal text names the three approaches it can touch: the alternative standardised approach in Articles 325c to 325ay, the alternative internal model approach in Articles 325az to 325bp, and the simplified standardised approach in Articles 326 to 361. This relief runs until a more permanent legislative act applies or, in the absence of one, for up to three years.

The second tool, in Article 461a(2)(b), lets the Commission postpone for up to two years the date from which institutions apply the market risk own funds requirements in Part Three, Title IV. That is the postponement limb. It is the lever the Commission pulled twice already, and it is the lever that is now spent.

So when you read that the Commission used its CRR empowerment, the precise limb is Article 461a(2)(a), the multiplier. That is not a drafting nicety. The choice of limb tells you the legal runway: three years of relief, anchored to the 1 January 2027 application date, with a built-in expectation that a permanent legislative fix follows.

Why a multiplier and not a third postponement

The simplest question a reporting officer will ask is why the EU did not just push the date again. The answer is that it ran out of the legal ability to do so. Article 461a(2)(b) caps the postponement at two years, and the Commission has now used both.

Trace the timeline. CRR3 set the FRTB as the binding market risk capital framework. The Commission first deferred its application by one year through Commission Delegated Regulation (EU) 2024/2795, moving the date to 1 January 2026. It then deferred a second year through Commission Delegated Regulation (EU) 2025/1496 of 12 June 2025, moving the date to 1 January 2027. Two years of postponement, both consumed. The EBA itself responded publicly to that second delegated act, which is a useful reminder that these moves do not happen quietly inside the Commission.

That is where the postponement limb dies and the multiplier limb takes over. With no power left to delay the date, the only instrument that remained for preserving a level playing field was Article 461a(2)(a). This is the trap teams fall into when they skim the news: they assume the EU found another year. It did not. The framework applies. The multiplier is what changes, and a multiplier lives inside the capital calculation rather than at the on/off switch.

How the multiplier works inside the own funds calculation

A multiplier under Article 461a(2)(a) is a factor equal to or greater than 0 and lower than 1. The empowerment permits targeted multipliers, and operational relief measures, for specific risk classes and risk factors within one of the named approaches. Under the adopted act, an adversely affected bank calibrates its own multiplier so that its FRTB own funds requirement for market risk, after the targeted amendments and after the output floor, scales down to the level of its pre-FRTB (Basel 2.5) own funds requirement. The objective is capital neutrality against that pre-FRTB position for the three-year relief period. It is a bank-specific factor between 0 and 1, not a single value the Commission publishes.

Article 325(1), as amended by CRR3, sets the menu of approaches the multiplier can attach to. An institution calculates own funds requirements for market risk for all trading book positions, and for non-trading book positions subject to foreign exchange or commodity risk, using the alternative standardised approach in Chapter 1a, the alternative internal model approach in Chapter 1b for desks that hold permission under Article 325az(1), or the simplified standardised approach where it meets the size conditions in Article 325a(1). The multiplier rides on whichever of these an institution uses.

One operational detail worth holding onto: an institution using the alternative internal model approach already reports, every month, the alternative standardised approach result for each trading desk, under Article 325(3). That parallel calculation does not disappear because a multiplier exists. If anything it becomes more sensitive, because the gap between the standardised and modelled numbers is exactly the kind of thing supervisors will watch when a relief factor is sitting on top.

The act pairs the multiplier with targeted, time-limited methodological amendments to the FRTB calculation for the relief period. The Commission has described these as targeted adjustments across the internal model and standardised approaches; confirm the specific amendments against the adopted act and its technical-implications Q&A before relying on any individual item. The core sensitivities, default risk charge and residual risk add-on machinery still runs, with the multiplier then applied on top.

What still applies from 1 January 2027

From 1 January 2027 the FRTB is the live framework for market risk own funds requirements. The multiplier reduces the resulting figure for three years; it does not suspend the requirement to compute it. That has three practical consequences that reporting and disclosure teams need to separate cleanly.

First, the own funds requirement. Banks compute market risk capital under the FRTB approaches from 1 January 2027, apply the targeted amendments, apply the output floor, then apply the multiplier so the result scales down to the pre-FRTB level. The number that flows to own funds is that post-multiplier, capital-neutral figure for the relief period.

Second, the output floor. The FRTB standardised approach feeds the output floor calculation, and the adopted act is explicit about how the multiplier interacts with it. Banks using the multiplier apply it after the output floor, so the floor sits inside the order of operations the relief has to account for. The multiplier is therefore not separate from the floor: it is applied to a figure that already reflects the floor and its phase-in. Build the calculation so the post-floor, post-multiplier figure is evidenced end to end.

Third, disclosure. Pillar 3 market risk disclosure continues to preserve market discipline. The Commission has been explicit through the postponement phase that current methodologies stay disclosed so the market can read a consistent picture. A relief multiplier introduced into the capital number raises a presentational question that disclosure teams should resolve early: showing the relieved figure without showing the gross FRTB figure hides the very competitiveness adjustment the measure is built around.

The COREP and reporting impact

Here is the part reporting teams care about most, and the part most likely to be misread. Through 2026 the existing market risk reporting templates continue to apply. The Commission confirmed that the existing market risk reporting templates under Commission Implementing Regulation (EU) 2021/451 and Commission Implementing Regulation (EU) 2021/453 remain in use until 1 January 2027, while FRTB reporting has run in parallel for monitoring purposes. Disclosure templates sit under a separate instrument, Commission Implementing Regulation (EU) 2021/637.

From 1 January 2027 the reporting picture turns over with the framework. The FRTB market risk reporting that institutions have been submitting for monitoring becomes the basis for the capitalised requirement. In addition, the act requires banks using the multiplier to also comply with the reporting and disclosure requirements for market risk own funds set out in Part Eight of the CRR in the version in force on 8 July 2024, so a supervisor can see both the FRTB-based figure and the pre-FRTB position the multiplier targets. The precise template and data-point mapping for the multiplier sits in the EBA reporting framework that accompanies the application date, and a reporting team should be tracking the relevant Data Point Model release rather than assuming the legacy market risk templates carry the new relief field.

This is where I would slow a project plan down. The instinct on a relief measure is to treat it as a reduction you book once and forget. A bank-calibrated multiplier applied after the output floor is not that. It needs a way to show the gross FRTB requirement and the post-multiplier figure, and a control that proves the multiplier brings the post-floor number down to the bank’s pre-FRTB level. The Article 354 correlated-currencies charge taught the same lesson on a smaller scale: a targeted factor that lives in one corner of the market risk calculation still has to be evidenced end to end. For the foreign exchange angle there, our note on the EBA correlated currencies framework walks through how a narrow market risk factor flows into the capital number.

Two things reporting teams commonly get wrong on this kind of change. The first is timing the build to the adoption date rather than the application date. The act was adopted on 4 June 2026, but it only takes effect after the scrutiny period and for reporting from 1 January 2027. The second is mis-ordering the calculation. The multiplier is applied after the targeted amendments and after the output floor, and is calibrated to the bank’s pre-FRTB level; applying it before the floor, or to an un-amended FRTB number, will misstate both the relief and the capital figure. If you want the broader COREP context for where market risk sits, our COREP reporting walkthrough maps the template families.

The level playing field rationale and the trading book boundary

The whole measure hangs on competitiveness. Article 461a is built around the difference between EU and third-country implementation, and the multiplier limb explicitly exists to preserve a level playing field and offset observed differences. The Commission’s stated concern is that EU banks would carry the full FRTB capital charge on trading activity while peers in jurisdictions that delay the standard would not, distorting competition in market-making and trading.

That framing has a boundary consequence people miss. The adopted act requires banks using the multiplier to apply the pre-FRTB trading book boundary (the CRR2 boundary) for the actual calculation of their own funds requirements throughout the three-year relief period, not only for the multiplier, so that they do not run two boundaries at once. This is consistent with the EBA no-action letter that told supervisors not to prioritise enforcement of the new CRR3 boundary until the FRTB is fully in place. Banks not using the multiplier are to be given the same flexibility, and the Commission has invited the EBA to provide clarity on the boundary framework until the act expires at the end of 2029.

This is also where the measure stops being self-contained. The relief is temporary by design, and the law expects something more durable to follow.

What comes next: the EBA report and a possible legislative proposal

Article 461a(3) sets a fixed waypoint. By 10 July 2026 the EBA is to submit a report to the European Parliament, the Council and the Commission on how third countries implement international market risk standards. On the basis of that report, the Commission may, where appropriate, bring forward a legislative proposal to secure a global level playing field.

Sequence those dates and the design becomes clear. The multiplier buys three years of relief from 1 January 2027. The EBA report lands in July 2026. If the Commission decides a permanent fix is needed, a legislative proposal would aim to land before the three-year relief runs out, so that the multiplier hands over to a durable regime rather than expiring into the full FRTB charge. For capital planning that means treating the relief as a bridge with an end date, not a permanent feature of the trading book capital stack.

The honest caveat is that none of the forward path is guaranteed. The delegated act still has to clear scrutiny. The legislative proposal is conditional on the EBA report and the Commission’s judgement. A reporting and capital team plans for the relief as adopted and watches the legislative track without baking an assumed permanent regime into a 2028 capital plan.

Frequently Asked Questions

Does the 4 June 2026 act delay the FRTB again?

No. It keeps the FRTB application date at 1 January 2027 and applies a multiplier to reduce the capital impact for three years. The power to postpone the date, in Article 461a(2)(b), was capped at two years and is already used up through Delegated Regulation (EU) 2024/2795 and Delegated Regulation (EU) 2025/1496.

What legal power did the Commission use?

Article 461a(2)(a) of the CRR, the limb that allows targeted operational relief measures or targeted multipliers equal to or greater than 0 and lower than 1, for specific risk classes and risk factors, within one of the approaches in Article 325(1). Article 461a was inserted in its current form by CRR3, Regulation (EU) 2024/1623.

How big is the multiplier?

The empowerment in Article 461a(2)(a) caps any multiplier at equal to or greater than 0 and lower than 1. There is no single Commission-set value: under the adopted act each adversely affected bank calibrates its own multiplier, applied after the output floor, so that its post-amendment, post-floor FRTB requirement scales down to its pre-FRTB (Basel 2.5) level. Confirm the calibration methodology against the adopted delegated act and its technical-implications Q&A before building the calculation.

Which approaches does the multiplier apply to?

Article 461a(2)(a) names the alternative standardised approach (Articles 325c to 325ay), the alternative internal model approach (Articles 325az to 325bp), and the simplified standardised approach (Articles 326 to 361). The relief attaches to whichever approach an institution uses under Article 325(1).

Do we still report market risk in 2026?

Yes. The existing market risk reporting templates under Commission Implementing Regulation (EU) 2021/451 and (EU) 2021/453 continue until 1 January 2027, and FRTB reporting runs in parallel for monitoring. From 1 January 2027 the FRTB reporting becomes the basis for the capitalised requirement, and the multiplier has to be visible in that reporting.

Does the multiplier change the output floor?

The multiplier is applied after the output floor, so the floored figure is the base the multiplier acts on. Build and evidence the calculation in that order, and confirm the exact treatment of the output floor and its phase-in against the adopted act, which industry bodies flagged as a point needing clarification.

When will we know if a permanent regime replaces the relief?

The EBA is to report on third-country implementation by 10 July 2026, and the Commission may then bring a legislative proposal. Plan the three-year relief as a bridge from 1 January 2027 and monitor the legislative track rather than assuming a permanent outcome.

Key Takeaways

  • The Commission adopted a delegated act on 4 June 2026 that applies a multiplier to offset FRTB market risk capital for three years from 1 January 2027. It is not another postponement.
  • The FRTB still becomes the live market risk capital framework on 1 January 2027. The multiplier reduces the targeted capital impact; it does not suspend the requirement to calculate it.
  • The legal basis is Article 461a(2)(a) of the CRR, the multiplier limb, used because the two-year postponement power in Article 461a(2)(b) is exhausted by Delegated Regulation (EU) 2024/2795 and (EU) 2025/1496.
  • The multiplier is a bank-specific factor between 0 and 1, applied after the output floor, calibrated so that a bank’s post-amendment, post-floor FRTB requirement scales down to its pre-FRTB (Basel 2.5) level. It is not a single value the Commission publishes; confirm the calibration methodology against the adopted act.
  • It is a delegated act with a three-month scrutiny period for the Parliament and Council, extendable by three months. The multiplier is bank-calibrated to pre-FRTB capital neutrality and applied after the output floor; confirm the calibration detail against the adopted act once it appears in the Official Journal.
  • Existing market risk reporting templates under Commission Implementing Regulation (EU) 2021/451 and (EU) 2021/453 run until 1 January 2027; from then the FRTB reporting carries the capitalised number and must show the relief.
  • The EBA reports on third-country implementation by 10 July 2026, and a legislative proposal may follow to make the level playing field more durable. Treat the relief as a bridge with an end date.

Reading the multiplier as a bridge, not a brake

The mistake to avoid is mental shorthand. This is not the EU stepping back from the FRTB. It is the EU switching the framework on while turning down the capital volume for three years, using the only dial Article 461a left it. The reporting work that follows is unglamorous and specific: map the relieved risk classes to the right cells, show the gross and net numbers, reconcile to the output floor, and keep the disclosure honest. Build to the 1 January 2027 application date, calibrate the multiplier to pre-FRTB capital neutrality once the delegated act is published, and watch the July 2026 EBA report for the shape of whatever replaces the bridge.
