How to Prepare a Credible Response to a PRA Capital Add-On Proposal

A PRA letter proposing a capital add-on is not an opening bid. It is a reasoned supervisory judgement, grounded in SREP analysis, peer data, and the PRA's own methodologies. Treating it as a negotiation is the fastest way to lose credibility. The firms that respond well treat it as a structured technical dialogue: they engage with the evidence, concede where the PRA is right, and push back only where they have genuinely better analysis.

Key Executive Takeaways

• A credible response is a technical document grounded in better evidence, not a commercial argument about the cost of capital.
• Governance of the response, who signs off, what the Board sees, how challenge is recorded, matters as much as the content.
• Concessions made early and clearly on areas where the PRA is right strengthen, not weaken, your position on the areas you contest.

Read the proposal properly before responding to it

The first mistake is reacting to the number. The second is reacting to the tone. Neither is the point. Work out what the PRA is actually saying: which risks are being capitalised, under which methodology (SS31/15, the Pillar 2A statement of policy, the PRA buffer framework), and what evidence base they have relied on. Identify whether the add-on reflects a methodology-driven calculation, a judgement overlay, or a response to specific control or governance findings. Each requires a different kind of answer.

Map the proposal against your own ICAAP. Where do the numbers diverge, and why? Is it a different modelling approach, a different stress calibration, a different view of diversification, or a different read of your risk profile? Precision here determines whether your response lands.

Build the technical rebuttal around evidence, not assertion

The PRA is unmoved by statements that management considers the add-on excessive. What moves the position is new or better evidence: loss data the supervisor has not seen, model validation work that addresses their specific concerns, scenario analysis calibrated to their stated worries, or independent assurance on controls they have questioned.

Structure the rebuttal risk by risk. For each contested element, state the PRA's position, your position, the evidence supporting your position, and the residual uncertainty. Be explicit about what you accept. Firms that contest every point lose authority on the points that matter.

If the add-on reflects control weaknesses, the only credible response is a remediation plan with dates, owners, and assurance milestones, together with a view on when the add-on could reasonably be reconsidered. Arguing the controls are fine when the PRA has concluded otherwise rarely succeeds and damages the relationship.

Govern the response as a Board-level matter

The response should be owned by the CRO and CFO jointly, with the Board Risk Committee reviewing the substantive analysis and the Board approving the final submission. Minute the challenge. If internal audit or an independent party has reviewed the technical work, say so. The PRA reads for signs that the firm has engaged seriously at the top, not just at the second line.

Use the supervisory relationship. Request a technical meeting with the line supervisor and the relevant risk specialists before submitting written representations. This is standard practice and surfaces misunderstandings before they harden. Come with specific questions and specific evidence, not general concerns.

What good looks like

A strong response is short, structured, and quantitatively precise. It opens with what the firm accepts. It sets out contested areas with evidence that is new, verifiable, and relevant to the PRA's stated methodology. It commits to remediation where remediation is warranted. It avoids rhetoric about competitive impact, dividend policy, or peer comparisons the firm cannot substantiate.

What goes wrong, consistently: tone that reads as aggrieved; technical arguments made by people who were not involved in the original ICAAP; late escalation to the Board; and a failure to distinguish between the add-on itself and the underlying supervisory concerns that produced it.

The decision point

Before you submit, ask one question: if the PRA accepted every argument in this response, would a reasonable supervisor still have residual concerns about the risks they identified? If the answer is yes, the response is not finished.

Frequently Asked Questions

How long should the written response be?

Typically twenty to forty pages for the main submission, with technical annexes. Longer responses signal that the firm is reaching. The PRA values precision over volume.

Should we involve external advisers?

For the technical modelling and benchmarking work, often yes, particularly where independent validation strengthens the evidence. For the drafting and tone of the response itself, keep it internal. Submissions that read as having been written by advisers lose credibility quickly.

What if we fundamentally disagree with the PRA's methodology?

Say so, clearly, with reasoning. But recognise that methodology disputes rarely succeed in a single response. The more productive path is to engage through industry channels on methodology and respond to the specific proposal on its merits.

When should the Board see the draft?

Twice: once at the point of agreeing the response strategy and contested positions, and once to approve the final submission. A single sign-off at the end suggests the Board has not genuinely engaged.

How does this affect the ongoing supervisory relationship?

A well-argued response, even one the PRA ultimately rejects, strengthens the relationship. A poorly argued or defensive response weakens it for years.
