How private debt managers can scale their success by optimizing their operational models

The private debt industry has experienced significant growth during the last decade and has delivered impressive performance throughout the rising interest rate cycle. With forecasts pointing to further increases in private debt assets under management (AUM) in the years ahead, private debt managers will have to upgrade their operational infrastructure to support their rapidly-expanding franchises and better connect front, mid, and back-office functions.

In what has been a challenging period for alternative investment managers, the private debt asset class has been a standout performer.

According to McKinsey, private debt generated stronger returns than all other private market asset classes in 2023 and was the most resilient for fundraising.

Rising interest rates benefited private debt firms, due to the floating rate structures that gains when base rates climb. This has driven ongoing investor demand for the strategy, proving its ability to deliver attractive risk-adjusted returns across the investment cycle.

The robust performance of private debt strategies through the recent period of market dislocation and uncertainty follows a period of remarkable growth for the asset class.

Private debt assets under management (AUM) have more than quadrupled during the last decade, according to Preqin figures, and currently stand at approximately US$1.6 trillion. And according to BlackRock, the private debt industry is well-positioned to sustain its growth trajectory. AUM forecast is set to reach US$3.5 trillion by the end of 2028 as borrowers continue to favor the bespoke and flexible financing structures offered by private debt managers, and investors, many of which are under-allocated to private debt, move to grow their exposure to the asset class.

Preparing for the next cycle of expansion

For private debt managers, the rapid increase in industry AUM has brought their franchises to an organizational tipping point.

Private debt firms are not only managing larger pools of capital for a more diverse, demanding investor base, but are also executing increasingly complex investment strategies that have expanded beyond bilateral, middle-market loans into big-ticket club deals and opportunistic purchases of debt tranches.

Unlocking capital from a global investor base and expanding deal pipelines into new areas have opened exciting opportunities for managers. However, capitalizing on these prospects will require private debt firms to upgrade their operational infrastructure to sustain their growth.

Managers have not only had to enhance their back-office fund accounting and investor reporting functions to serve an increasingly demanding and sophisticated investor base, but also their middle-office loan servicing and loan administration services to borrowers and the companies to which they lend.

The lean operations that supported private debt through its first phase of expansion will have to be upscaled to ensure that managers can maintain operational nimbleness, and the ability to measure performance while tracking risk, as transaction volumes rise.

Increasing middle and back-office capabilities do pose operational challenges for managers. Staff and technology costs ramp up, while the impacts of additional processes, sign-offs and internal bureaucracy can compromise the agility and responsiveness that have underpinned previous success and growth.

It has also become crucial for managers to establish seamless links between front-office dealmakers, middle-office, and client-facing teams that support borrowers, and back-office teams managing fund accounting and reporting.

Key areas for consideration

As private debt managers enter the next phase of the asset class’s evolution, there are three key questions that should be asked before embarking on an operational overhaul: 

  1. Does integration exist through the front, middle, and back office?

While the oversight and investment management of a private debt fund does have similarities with other alternative asset classes such as private equity and real assets, there are specific deal structuring and fund accounting requirements that are unique to private debt. 

Loan structures, for example, will include multiple tranches, varying rates and payments of principals and interest. Managers must also be able to source and analyze data in markets where public information is less available than in syndicated loan and bond markets. 

The fund accounting required to track and report on private credit portfolios and investments is also vastly different from what is required in private equity portfolios, for example.

As managers expand, it is essential that their accounting and operating teams have the requisite experience to handle the specific demands of private debt fund accounting and reporting. 

It is equally important for private debt managers to have the middle-office capabilities to take loan agency responsibilities, such as for individual investments, handle all trade settlements and interest rate payments, and to administer borrowing bases. 

  1. Outsourcing or in-house? 

Managers must decide if it is best to outsource both back- and middle-office functions as their operations grow or invest in building additional infrastructure in-house.

Keeping operations in-house gives managers direct control of loan operations, fund accounting, and data, which has its advantages, but does come with high upfront costs and makes it more difficult to scale up back-office resources in the future.

Outsourcing to a third-party provider allows managers to benefit from the global reach and extensive industry expertise of fund administration specialists. It is also important to factor in that when a manager ramps up the size of internal teams, the GP bears those costs. In contrast, when outsourcing, the costs of administration are covered by the fund.

If managers do choose to go down the outsourcing route, it is crucial to have clarity on what infrastructure and technology will have to be retained internally to oversee, engage, and interact with a third-party fund administrator.

Managers must also be clear on the scope of work that a loan servicer and fund administrator can handle. Not all partner firms, for example, can deliver portfolio accounting via their loan administration systems.
Managers should be clear on exactly what support they require and whether the administrator can meet that request.

  1. How will data challenges be addressed? 

Data management poses distinctive challenges in a private debt context, as different teams within a firm have different technology and data requirements.

Investor relations teams, for example, want to access performance data to report to LPs, while operations teams prioritize the data requirements of investment professionals and fund accountants want to ensure that books are up to date.

This has seen the asset class move away from single systems, which aim to cover the full loan cycle and serve as a “single source of truth,” to a model where there is an interlinking patchwork of technology platforms and servicing teams.

As data linkages between different operations and teams grow in importance, the middle and back office must become more fluid and integrated.

Ensuring that the data linkages between these teams and their respective technology tools are fully integrated and seamless is complex and impacts how back-office and mid-office functions are structured.

Whether outsourcing or keeping operations in-house, firms must ensure that operating models are structured in a way that aligns the back office and middle office teams and helps to facilitate the “front-to-back” integration required to support multiple complex front office investment management tasks.

Curating an operating infrastructure that covers these priorities and meets the specific demands of each individual private debt manager lays a firm foundation for building a scalable operational model that can grow with a private debt platform. 

The value of a supportive loan servicing and fund administration partner

Transforming an operating model is demanding and can distract managers from their core front office investment management priorities.
