PRA proposes automatic rises for regulatory thresholds

The Prudential Regulation Authority has proposed an automatic system for increasing 128 financial services regulatory thresholds, replacing periodic manual adjustments with a framework linked to growth in the UK economy. Qualifying thresholds would be updated every five years using nominal gross domestic product, with the first automatic adjustment proposed for 1 July 2031.

The thresholds determine when particular prudential rules apply to banks, insurers and credit unions, as well as how some requirements are calculated or reported. Static cash values can become progressively more restrictive as prices and the economy grow, creating what the PRA calls “prudential drag” when institutions cross regulatory boundaries even though the risk those thresholds were originally designed to capture has not increased to the same degree.

The scale of the exercise is broad. At the upper end, the proposals include the £320bn total assets threshold used for detailed capital reporting, while at the other end sits a £7,500 threshold covering amounts owed to a credit union by an individual. The package also reaches thresholds affecting the Small Domestic Deposit Takers regime and the application of Solvency UK requirements.

Reporting accounts for the largest part of the proposed scope, with 52 of the 128 thresholds, while 31 relate to the regulatory perimeter of a regime or definition, 25 to methodologies and approaches, 12 to lending, funding and investment flexibility, and eight to internal governance, policies and procedures. The breadth means institutions would see the mechanism applied across several areas of compliance rather than to a single prudential regime.

Automatic adjustment would nevertheless stop short of becoming a blanket rule for every numerical limit. The PRA proposes excluding measures where indexation could undermine the original policy intent, where the change cannot be made through PRA processes, where the threshold is not expressed as a nominal amount or where an adjustment could materially change prudential outcomes and therefore requires specific policy judgement.

That distinction preserves regulatory discretion while reducing the need for repeated consultations whose main purpose is simply to refresh monetary values. Thresholds carrying a greater policy or risk consequence would continue through ordinary rulemaking, while those that can be adjusted consistently would follow the five-year cycle.

Nominal GDP was selected because it captures changes in both economic activity and prices. The PRA considered alternatives including consumer price inflation and real GDP growth, but neither reflects the full increase in the nominal size of the economy in the same way. Using published Office for National Statistics data also gives the process an external reference point rather than leaving each adjustment dependent on a new regulatory judgement.

For regulated businesses, a predictable mechanism could improve planning around capital, reporting and systems because future monetary boundaries would be less likely to remain frozen for long periods. A growing institution could still cross into a more demanding regime, but the threshold itself would move with the wider economy instead of tightening inadvertently through inflation and nominal growth.

The effect would not always reduce regulatory requirements. Some thresholds operate in the opposite direction, meaning an increase can raise obligations or reduce flexibility, so the proposal is better understood as an attempt to preserve the intended calibration of the rules than as a general deregulatory measure.

That calibration also sits within the PRA’s wider competitiveness and growth responsibilities. Maintaining proportionality can reduce unintended barriers as institutions expand, although the regulator still has to preserve safety and soundness and ensure that automatic changes do not weaken prudential outcomes.

If adopted, the five-year mechanism would establish a common process across banking, insurance and credit unions for a large set of monetary thresholds. The change is mechanically simple, but its significance comes from replacing a series of irregular manual interventions with a repeatable system tied directly to the nominal development of the UK economy.
