Range has risen up the agendas of companies, regulators, and governments lately. How various are the higher echelons of banks and constructing societies within the UK? We reply this query in a latest paper utilizing a singular knowledge on essentially the most senior staff for the final 20 years.
The information
Arguments for growing range inside banks often stem from at the least one in all two views: fairness and effectivity. Our paper addresses each of those views. First, we set up the information and tendencies of range in UK banks during the last 20 years. Second, we look at whether or not extra various banks have higher outcomes.
We convey collectively data on all accepted management and senior supervisor features (2001–20) – ie all senior supervisor, government and oversight roles which require regulatory approval. We construct an information set of the id traits of senior managers for gender, age and nationality range in all PRA-regulated banks during the last 20 years (complete of 181).
The nice, the dangerous and the ugly
Probably the most attention-grabbing tendencies are in relation to gender range, so we are going to give attention to these findings right here.
The excellent news is that, general, gender range has improved in UK banks during the last 20 years. The dangerous information is that that is an enchancment upon a really low base and that progress has been very sluggish. Chart 1 reveals this pattern, plotting the proportion of girls in senior positions per quarter. Just below 10% of positions had been stuffed by girls on the finish of 2001, whereas this determine is now slightly below 20%. In any other case acknowledged, only one in 5 senior positions are held by girls in UK banks.

Issues get uglier after we decompose the pattern by position. Right here we discover proof of a ‘glass ceiling’ working in UK banks – essentially the most senior roles have seen the least and slowest progress, whereas the extra junior positions have seen sooner enchancment. Chart 2 reveals the tendencies for 4 classes of features: CEOs; government; oversight (non-executive administrators); and threat/compliance/audit personnel. The comparatively junior threat/compliance/audit positions elevated on the quickest relative tempo and CEOs on the slowest relative tempo. Certainly, just below 10% of CEOs had been girls by the top of the pattern time interval. The breaks within the pattern strains by perform are as a result of adjustments within the regulatory regime throughout our interval of research, which led to adjustments in a few of the populations captured.
Lastly, we present that shut to twenty% of all banks didn’t have any feminine illustration in authorised positions on the finish of 2020, which is down from roughly 40% in 2001.

Does range have an effect on financial institution outcomes?
This can be a robust query to reply with the info we now have. In a super analysis set-up, we’d randomly allocate range throughout banks. That approach we’d not have to fret about all the opposite variations between banks as a result of they might stability throughout people who had been ‘handled’ with range and people who weren’t as a result of randomisation. The true world is messier – it is vitally onerous to account for all of the variations that may exist between corporations to isolate the causal impact of range.
We subsequently attempt to approximate an experimental design utilizing Coarsened Actual Matching (CEM). This method creates an artificial remedy and management group by discovering banks which are precisely or roughly the identical throughout all dimensions we will measure (and deemed related) whereas differing solely by way of range. Utilizing this method, we discover that gender range is related to improved monetary efficiency (measured by the return on belongings ratio) and decreased riskiness (measured by the Z-score distance to default measure). For instance, we discover {that a} one customary deviation improve within the share of females in authorised positions (a rise of 12 share factors) is related to an anticipated discount in threat of failure by round 9 share factors.
Whereas the CEM method offers proof that range is related to higher outcomes (ie higher returns and decrease riskiness), after we look at whether or not adjustments in range over time inside corporations impacts outcomes (using common methodology of moments regression fashions), we discover a null outcome.
Our findings are subsequently combined. Whereas we do one of the best we will to establish the causal relationship between id range and agency outcomes given the info accessible to us, these findings include a reliability warning. Within the absence of some type of pure experiment, we’re unable to manage for all related elements which can have an effect on each range and outcomes, and so we cease wanting claiming that these findings are causal in nature.
What subsequent?
Whereas our outcomes are combined and include caveats round causality, taken collectively they recommend the Prudential Regulation Authority (PRA) is justified in encouraging better range in UK banks, each from an fairness and effectivity perspective.
There may be rather more to research. One avenue for future analysis is to increase the vary of range variables accessible for evaluation to people who are doubtlessly extra intently associated to cognitive range, for instance range of academic {and professional} expertise. This side is necessary as a result of id range would possibly matter for outcomes solely insofar because it results in cognitive range.
The constraints of our knowledge have a number of classes by way of the reporter necessities the PRA locations on regulated corporations. To higher perceive the information of range and its relationship with agency outcomes, extra knowledge on demographic traits are wanted. Notably, the PRA don’t at the moment collect knowledge on necessary demographic traits, eg ethnicity of people in regulated corporations. A latest Dialogue Paper, nonetheless, units out potential methods to remediate this, and whether or not metrics for inclusions would even be useful.
