The Closed Pool: Why Some Finance Skills Cannot Be Hired Into
Most shortages in professional hiring are cyclical. Demand rises, salaries follow, more people train, supply catches up, and the premium erodes. That is the normal mechanism and it works — slowly, imperfectly, but it works. There is a category of finance expertise where it does not work at all, because the experience can only be acquired inside firms that already possess it. The result is a closed loop: firms need people who have done it, and the only place to have done it is inside a firm that needed people who had done it. This article is about that closed pool — where it exists, why it persists, and what employers and finance professionals should do about it.
What makes a pool closed
Three conditions have to hold together, and where they do the shortage becomes structural rather than temporary.
The obligation exists only in certain firms. Client money reconciliation, safeguarding, prudential capital calculation and regulatory reporting are not things a commercial business does badly — they are things it does not do at all. There is no equivalent to learn on.
The learning is experiential rather than theoretical. The rules are published and free. What is not published is the judgement: which differences matter, what an expanding scope looks like before it expands, what is reportable, and what a supervisor will ask. That comes from having done it.
And the consequence of error is external. A firm cannot let someone learn on the job as its sole resource, because the cost of a mistake is a shortfall, a breach or a supervisory conversation. So the roles are filled by people who have already done it — which is precisely what keeps the pool closed.
Contrast that with, say, consolidation. Group accounting is technically demanding and genuinely scarce, but it can be learned inside any business that has a group structure, with a senior person checking. The pool is small; it is not closed. Regulated finance is different in kind.
Where the closed pools are
In UK finance, four stand out.
Client money. The CASS regimes govern how firms hold money belonging to clients, and they differ enough between sectors that experience is not even fully transferable within the category — a specialist from an investment firm is not interchangeable with one from an insurance broker, as our comparison of CASS 7 versus CASS 15 sets out. It is the tightest pool in UK finance and the roles command it: our CASS accountant job description and salary guide covers what firms are paying.
Prudential reporting. Own funds, regulatory capital requirements and the returns that follow. Learnable in principle, acquired in practice only inside authorised firms, and concentrated in remarkably few heads — frequently one per firm, with nothing documented.
Safeguarding in payments and e-money. A growing sector with a genuinely thin supply, and one where the closed-pool problem produces a specific and common hiring failure discussed below.
And specialist tax disciplines — investigations, complex VAT, employment tax at scale. Adjacent to the pattern rather than identical, because practice provides a training ground the regulated disciplines lack, but the same scarcity dynamics apply, as our guide to the personal tax manager market illustrates from the other direction: a discipline with plenty of practice supply and almost no in-house demand.
What the closed pool does to pay
The premium in regulated finance runs at roughly ten to twenty per cent over equivalent commercial roles, and the striking feature is that it does not erode. Cyclical premiums compress when supply catches up; this one has held for as long as I have watched it, because supply cannot catch up through the normal mechanism.
It also does not compress with seniority, which is unusual. In most disciplines the scarcity premium is largest early — a rare technical skill matters more at three years than at fifteen, when general capability dominates. In closed pools the reverse applies: someone with eight years of client money or prudential experience is scarcer at that point than they were at three, because the pool does not deepen. Our regulated-firm finance salary guide sets out where the premiums actually sit by discipline.
One further consequence worth naming: the premium is not compensation for difficulty. Client money reconciliation is not conceptually harder than a complex consolidation. It is compensation for scarcity, and confusing the two leads employers to under-value the roles and candidates to over-explain their value.
The hiring failure the closed pool produces
Because the pool is closed, employers under pressure to fill a role reach for adjacency — and adjacency is where the specific, recurring mis-hire happens.
The clearest example is in payments. A large share of businesses that describe themselves as fintechs operate as agents or distributors of an authorised principal firm. Their finance people have never safeguarded anything, because the principal does it. The CV looks right, the sector matches, and the experience is absent. The question that prevents it takes ten seconds — was your firm authorised, and did it hold relevant funds? — and it is asked far less often than it should be.
The same pattern appears elsewhere. A candidate with CASS 7 experience applying for a CASS 5 role in a broker; a strong statutory accountant applying for a prudential reporting role; a commercial Financial Controller applying into an authorised firm. In each case the adjacency is genuine and the specific experience is not, and our comparison of regulated versus commercial financial control works through which parts actually transfer.
The useful reframing for employers is this: the question is not whether the candidate knows the regime. It is who in your business would notice if they got it wrong. Where there is genuine expertise elsewhere — a compliance lead, an engaged adviser, an existing specialist — a capable adjacent candidate with strong control discipline is frequently the better and faster appointment. Where there is not, and the role is the sole finance resource, that is the configuration in which breaches go unnoticed longest.
How the pool actually gets entered
Given the loop, how does anyone get in? Three routes account for almost all of it, and only one is reliable.
A general finance role at an authorised firm. The reliable one. A management accountant or financial accountant position where the regulatory work sits alongside you rather than on you. Within two years you have absorbed enough to move into a specialist role, and you are inside the pool. This is what I recommend to almost everyone asking.
Auditing regulated clients. Practice auditors who have tested client money or regulatory returns arrive with a genuine head start, because auditing a control teaches you what it is for. An under-used route in both directions — firms rarely think to look there.
Interim assignments, which regulated firms use frequently and which are a legitimate way to acquire the experience for someone already strong in financial control.
What does not work is applying directly into a specialist role from a purely commercial background, and the reason is the closed loop itself: firms buying that expertise are buying it because they lack it, so they cannot supervise someone learning it. Candidates weighing the move will find our guide to preparing for a regulated-firm finance interview useful on what employers actually test.
The other closed pool: fund accounting
Worth naming because it is less discussed and has the same shape. Fund accounting sits alongside the management company’s own finance function rather than inside it, and the skills are genuinely separate: net asset value production or oversight, valuation, fee and carried interest calculation, investor allocations. A strong financial accountant is not a substitute, and vice versa.
The closed-pool dynamic operates identically — the experience is acquired at fund administrators or asset managers and almost nowhere else — with an added complication, which is that production and oversight are themselves different jobs. Someone whose career has been producing NAVs at an administrator frequently finds reviewing an administrator’s work from the manager’s side unsatisfying, and the mismatch is invisible on a CV. Our fund accountant job description and salary guide covers the distinction and what employers should specify.
What employers should do differently
Four things, none of them expensive.
Name the regime in the advert. “CASS 5 client money, non-statutory trust, mixed risk transfer” reaches a small but correct pool. “Regulated environment experience” reaches everybody and filters nobody.
Ask the authorisation question at screening. Ten seconds, and it prevents the commonest mis-hire in the sector.
Stop requiring the full stack. Client money, prudential reporting, Consumer Duty MI and statutory accounts, at manager level, on one salary, in a closed pool, produces no shortlist at all.
And take the key-person problem seriously before it becomes a hiring problem. A great deal of current demand in this market is firms discovering that one person owns the calculation, the reconciliation and the returns, with nothing written down. Documentation is cheaper than recruitment and it makes the eventual hire easier.
And what professionals should take from it
If you are inside one of these pools, the practical implication is that your position is stronger than a general market view suggests, and it strengthens rather than decays with time. The honest counterweight is optionality: moving back out is harder than moving in, because commercial businesses do not value client money experience, and a record that is heavily regulatory can read as narrow. People who want both tend to keep a foot in general financial control alongside the specialism.
If you are outside and want in, the route is unglamorous and it works: stop applying for the specialist roles and start applying for the general ones at authorised firms. Firms hiring a CASS specialist need someone who already is one. Firms hiring a management accountant will happily take a good candidate and let the regulatory knowledge accumulate — and two years later, you are inside the pool.
A Note from Our Founder — Adrian Lawrence FCA
The closed pool is the most durable feature of the market I recruit into, and it is the reason regulated finance premiums have held through periods when commercial hiring slowed. What I would say to employers is that the answer is almost never to wait for the perfect candidate, because in a closed pool waiting does not improve the odds — it just delays the hire. The answer is to be precise about which regime you actually need, honest about who in your business could check the work, and willing to take strong adjacent experience where that check exists. And if one person currently owns your client money reconciliation, your returns and your capital calculation with nothing documented, that is the search I would start before the audit asks about it rather than after.
