Private markets are growing. Back offices are struggling to keep up

Private markets are now a core part of the financial system. They fund companies and provide credit where banks no longer serve. In the US, SEC staff data shows that private equity funds alone reported roughly US$7.2tn in net assets at the end of 2024: scale that puts a premium on robust valuation processes, controlled calculations and investor-ready reporting.

Scale like that brings scrutiny: as private markets grow, weaknesses in valuation, reporting, or controls can affect far more investors. In private capital, the risk is not minute-by-minute repricing, because the asset class is built for long horizons. The bigger pressure point is operational: the back office has to translate complex fund structures into accurate books, defensible valuations and investor-ready reporting, then repeat the process under tighter deadlines.

Structural complexity has outgrown the operating model

Private funds were always complex but used to be easier to manage. A small set of vehicles, a largely institutional investor base and quarterly reporting left room for manual workarounds.

That world has moved on. Fund structures now stack and branch to meet jurisdictional needs, support co-investments, run continuation arrangements, reflect bespoke fee and carry logic. One portfolio can pass through multiple entities and SPVs before it reaches the underlying asset.

Asset coverage has broadened too. Private equity sits alongside private credit, infrastructure and hybrids, each with its own transaction detail and accounting requirements. Operations teams have to support that breadth without building a separate workflow for every exception.

The investor base has changed as well. Institutions remain central, but wealth managers and retirement channels play a bigger role in distribution. That wider mix raises expectations for timeliness and tailoring, especially when a manager runs multiple products with different reporting requirements.

Adding to the challenge, private markets remain relatively illiquid by design but the expectations around transparency have changed significantly. Investors no longer only ask for a quarterly snapshot and a PDF pack. They want to understand what is driving returns, how valuations were formed and, when needed, be able to trace numbers back to the underlying positions.

That shift is showing up in oversight too. In the US, the SEC’s fiscal-year 2026 examination priorities make clear that private fund advisers remain a focus, with attention on core pressure points such as valuation, fees and disclosures, especially where firms are newer to advising private funds or moving into less liquid assets.

Globally, the International Organization of Securities Commissions (IOSCO) is consulting on updated valuation recommendations for funds holding illiquid and private assets, adding more explicit expectations on governance, conflicts and record-keeping. At the system level, the Financial Stability Board’s latest monitoring flags both the continued expansion of non-bank finance and the data limitations that make private finance exposures harder to map – themes the IMF also echoes as non-bank credit channels deepen and retail participation grows.

In addition, in a CFA Institute survey of investment professionals, respondents highlighted concerns around how often valuations are reported and how reliable they are, alongside calls for greater fee transparency in private markets.

The operational consequence is simple: the time allowed to explain the numbers is shrinking. That is most obvious in evergreen credit products, where more regular NAV-based dealing can require valuations to be produced monthly rather than quarterly. When the window tightens, offline reconciliations and spreadsheet models stop being “just how the back-office works” and become a repeatable source of control risk.

The real fault line is the spreadsheet outside the system 

Many private funds are still trying to meet today’s demands with yesterday’s tools. Managers and administrators often run core processes on platforms that are 15 to 20 years old, then rely on spreadsheets and manual steps to fill the gaps. Data gets exported, rekeyed, reconciled offline and pasted into reporting templates to get packs out the door.

When activity is low, that setup can feel workable, but it does not scale when the fund gets complex. Pressure spikes when funds are raising, deploying, restructuring or winding down. Those are the moments when volume increases, structures change and investors and auditors ask more detailed questions. If key numbers are being stitched together across side files and email threads, the chance of inconsistency rises fast, while the cost of getting it wrong increases.

However, spreadsheets are not the enemy. They are a useful interface for modeling, sense-checking and review. The risk starts when spreadsheet logic becomes the real source of truth, with critical calculations sitting outside controlled workflows. Teams end up managing versions instead of managing outcomes, and confidence in the numbers becomes harder to defend.

Auditability needs the right definition

Audit trails often get lumped into the same bucket as investor and regulatory reporting. They are related, but they are not the same thing.

A strong audit trail means a firm can prove what happened inside the system, who did it and when it happened. It also means the firm can investigate quickly when something goes wrong. That is what auditors care about and what operational leaders need when deadlines are tight.

When critical work is scattered across emails, files and spreadsheets, that evidence becomes slow to assemble and easy to challenge. This typically results in longer audits, further follow-up questions and more time spent recreating history instead of running the business.

Fund administrators feeling the strain

Many private capital firms push more work to fund administrators so they can focus on investing. That shift concentrates complexity where scale is already hardest.

Administrators run many clients across asset classes and structures. Activity can surge across several clients at once. If the platform depends on offline reconciliations and manual uploads, workload can spike beyond what teams can safely absorb.

For fintech leaders, this is where the opportunity sits. The market needs operations that can handle rising complexity without scaling risk at the same rate.

What modernization looks like in practice

Modernization is often framed as a system replacement. The real goal is to reduce operational risk while increasing throughput and control. It starts with the data model. Firms need a single flexible data model that can represent the real structure, not a simplified version of it. If a platform cannot model the fund as it exists, teams end up tracking the missing pieces in “side files”: usually spreadsheets and offline logs for items like fee terms, waterfalls, and allocations, and then reconciling those back into the core books and reports.

That is only half the picture though. Complex modeling also needs to sit inside the platform, in order to access up-to-date data. Equally, private funds will always require bespoke calculations. The question is whether those calculations sit in uncontrolled spreadsheets or in secure, versioned tools that capture inputs, approvals and outputs. When modeling stays inside the system of record, results can flow directly into reporting without rekeying.

Integration must be built in. A modern platform should connect cleanly to upstream and downstream systems through open APIs so data can be shared without constant exporting and manual uploads. This reduces double entry and improves consistency across investor reporting, treasury processes and data warehouses.

Once that connectivity is in place, the goal is straightforward. Private markets do not need live, second-by-second reporting. They do need numbers that can be produced reliably on a tighter cycle, with a clear trail back to source data. That is why the foundation matters. AI may improve search and request handling, but it will not fix broken data foundations.

The takeaway: treat the back office as a risk surface

Private markets can tolerate illiquidity. They cannot tolerate opaque operations.

Firms that modernize their back-office foundations spend less time reconciling and more time analyzing. They answer investor questions faster because the evidence is already in the system. Audit cycles become smoother because approvals and changes are captured automatically. Most of all, these firms can support new structures and new investor expectations without turning every close into a fire drill.
