PRA confirms FRTB internal models delayed to 2028, Barclays capital impact guidance broadly unchanged

Overview

This report focuses on the UK PRA's latest statement on the final Basel rules and the implementation timeline for FRTB internal models. The PRA confirmed that, except for the FRTB components related to market risk internal models, the UK's final Basel rules are still scheduled to take effect in January 2027; the FRTB internal model components will be implemented in January 2028. Goldman Sachs views this as mildly positive for Barclays because the PRA's consultation proposals include several adjustments that support international consistency and proportionality, but they have limited impact on Barclays' previously provided guidance of an approximately £3-10bn increase in RWA.

Core views

The core views include: first, the PRA has not changed the overall implementation timeline of the final Basel rules, only keeping the FRTB internal model-related parts for implementation in 2028. Second, Barclays has already incorporated the related impact into its guidance and had previously stated that it may choose to defer some FRTB elements to 2028. Third, Barclays believes the output floor will not become a binding constraint at any point, and expects the Pillar 2A requirement from January 2027 onward may benefit from adjustments that avoid double counting. Fourth, compared with UK peers, NatWest expects Basel 3.1 to bring an approximately £10bn increase in RWA in January 2027, while Lloyds expects an approximately £6-8bn decline in RWA on day one.

Analysis framework

The report combines regulatory event analysis, Barclays' capital guidance, peer comparison of RWA impacts, and target price valuation. On the regulatory side, it focuses on assessing the PRA's consultation direction regarding FRTB internal models, the profit and loss attribution test, treatment of limited trading data, capital calculation when internal and standardized approaches are used together, and operational simplification; at the company level, it examines whether these changes would alter Barclays' RWA and CET1 impact; at the valuation level, it maintains a target price framework based on a P/E multiple.

Methodology notes

• Valuation methodP/E methodology

  Weighted P/E valuation based on 2027/28E EPS

  Goldman Sachs weights 2027E and 2028E EPS at 75%/25% and applies a 9.0x P/E multiple to derive Barclays' 12-month target price of 630p.

• Regulatory capital analysisBasel / FRTB impact assessment

  RWA and CET1 sensitivity assessment

  The report uses Barclays' guided range of approximately £3-10bn increase in Basel RWA to gauge capital impact, and notes that this range is equivalent to roughly a 10-40bps CET1 impact; a low-teens bps Pillar 2A offset is considered reasonable.

• Factor frameworkGS Factor Profile

  Growth, Financial Returns, Multiple, and Integrated percentile comparison

  Goldman Sachs Factor Profile compares individual stocks with the coverage universe and industry peers across growth, financial returns, valuation multiples, and integrated percentiles, as a supplement to the investment backdrop.

• M&A probability frameworkM&A Rank

  Acquisition target probability ranking

  Goldman Sachs classifies covered companies into ranks 1 to 3 based on the probability of being acquired; 1 represents high probability, 2 medium probability, and 3 low probability, and some rankings may factor into the target price.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Barclays Plc (BARC.L)

  Covered company and primary investment target

  Strengths

  Buy rating maintained; direction of regulatory adjustments is mildly positive; the output floor is not expected to become binding; a potential Pillar 2A offset may ease Basel capital impact.

  Weaknesses

  Basel in January 2027 may still bring an approximately £3-10bn increase in RWA, creating about 10-40bps of pressure on CET1.

  Comparison

  Compared with NatWest's approximately £10bn increase in RWA and Lloyds' approximately £6-8bn decline in RWA, Barclays' impact range sits in the middle and depends on FRTB and Pillar 2A details.

  Risks

  A slower recovery in IB capital markets, weaker US data affecting the USCB, a higher UK bank tax rate, or faster UK policy rate cuts or a lower terminal rate.

• Barclays plc ADS (BCS.US)

  US depositary security of the same issuer

  Strengths

  Linked to Barclays Plc's fundamentals and regulatory capital themes.

  Weaknesses

  ADS performance remains affected by the underlying stock, exchange rates, and cross-market valuation differences.

  Comparison

  The report's company disclosures list prices for both Barclays Plc and Barclays plc ADS.

  Risks

  In addition to Barclays' fundamental risks, exchange rates and ADR market liquidity also warrant attention.

• NatWest Group (NWG.US)

  UK banking peer comparison

  Strengths

  As a UK domestic banking peer, it provides a benchmark for Basel 3.1 capital impact.

  Weaknesses

  Guidance shows an approximately £10bn increase in RWA from Basel 3.1 in January 2027.

  Comparison

  NatWest's RWA increase is mainly driven by changes in infrastructure and SME support factors, and the report says it is not affected by this PRA announcement.

  Risks

  Basel 3.1 implementation and changes in UK banking regulation may still affect capital requirements.

• Lloyds Banking Group

  UK banking peer comparison

  Strengths

  Guidance indicates an approximately £6-8bn decline in RWA on day one in January 2027.

  Weaknesses

  Its commercial banking business uses Foundation ARB, unlike other commercial banks that typically use advanced ARB, limiting comparability.

  Comparison

  Unlike the RWA increases at Barclays and NatWest, Lloyds expects a reduction in RWA on day one.

  Risks

  Differences in model methodology and changes in regulatory capital definitions may affect peer comparison.

Impact & implications

For Barclays, the PRA announcement reinforces the narrative of increasingly flexible UK bank regulation, but does not significantly change the core assumptions of the company's capital planning. If the Pillar 2A offset materializes, it could partly cushion the CET1 pressure from Basel; however, higher RWA, FRTB implementation details, and the macro interest-rate path will still affect capital returns and valuation realization.

Risks

• IB capital markets recover more slowly than expected.
• US data weakens and weighs on USCB performance.
• UK bank tax rates rise.
• UK policy rates are cut faster than expected, or the terminal rate is lower than expected.
• The final implementation details of the PRA consultation proposals could change the actual impact of FRTB internal models and market risk capital requirements.
