Actuarial Consulting for Singapore Insurance: RBC2, IFRS 17 and When to Outsource

Actuarial consulting for Singapore insurance is the better route when a workload is project-shaped, specialist or temporary, and in-house hiring is the better route when the work is continuous and central to your control environment. Most insurers need both. The practical question is which workstreams belong in each bucket, and the answer has shifted as RBC2 and IFRS 17 have moved from implementation projects into permanent, recurring obligations.

This article sets out why the talent market is tight, which actuarial workstreams outsource well, which do not, and how to scope an engagement so that accountability and model knowledge stay with the insurer.

Why modelling talent is scarce in Singapore

Two regimes created overlapping demand for the same small pool of people. IFRS 17 (SFRS(I) 17 in Singapore) took effect for annual periods from 1 January 2023 and requires measurement of the contractual service margin, risk adjustment and discounting at a level of granularity that legacy valuation systems were not built for. RBC2, the revised risk-based capital framework supervised by the Monetary Authority of Singapore, changes the asset, liability and capital requirement calculations for licensed insurers and adds new demands on data lineage, parameter governance and management reporting.

The people who can build and maintain these calculations sit at an unusual intersection: life or general insurance technical knowledge, fluency in a projection platform such as Prophet or RAFM, enough programming skill to automate runs and reconcile outputs, and enough regulatory understanding to explain results to a board or to MAS. Each of the large insurers, reinsurers, brokers and consultancies in the region recruits from the same market. Job advertisements for roles citing RBC2, Prophet, RAFM and IFRS 17 appear continuously, which tells you the vacancies are persistent rather than seasonal.

For a mid-sized or newly licensed insurer the consequence is predictable. A vacancy takes months to fill, the person hired may leave once the model is stable, and a single key-person departure can leave the valuation team unable to reproduce last quarter's numbers. That risk sits directly in the operational risk register of any insurer that takes ORSA seriously.

Workstreams that outsource well

Outsourced actuarial services in Singapore work best where the scope is bounded, the deliverable is clear and the insurer retains ownership of the conclusion. The following categories fit that description.

Model build and migration. Rebuilding a projection model to RBC2 specification, migrating from one platform to another, or converting a spreadsheet-based process into a controlled model environment is a finite project. It needs deep platform skill for a few months, then much less.

IFRS 17 support during peaks. Opening balance sheet work, new product onboarding, the first run of a changed methodology and year-end disclosure preparation all create temporary spikes. Contracting IFRS 17 actuarial support for those periods avoids carrying permanent headcount for peak load.

Assumption setting and experience studies. Mortality, morbidity, lapse and expense studies require data work and judgement that smaller portfolios cannot always resource. A specialist team can run the study, document the credibility treatment and present recommendations to the insurer's actuarial committee.

Actuarial peer review. Material pricing, reserving and capital work benefits from review by a qualified actuary who did not produce it. Independence is the whole point, so this workstream is naturally external. See our overview of actuarial consulting for the types of review that are commonly commissioned.

Capital and solvency analysis. Projecting the capital adequacy position under stress, testing management actions and supporting the quantification behind the ORSA are analytical tasks that suit a project team. Our risk-based capital page describes the scope in more detail.

Regulatory remediation. Where MAS feedback or an internal audit finding requires documentation, validation or reperformance of calculations, a time-boxed external team can close the gap faster than a stretched internal one.

Workstreams that should stay in-house

Outsourcing does not transfer accountability. Under the Appointed Actuary regime for Singapore-licensed insurers, the Appointed Actuary and the board remain responsible for the valuation, solvency position and the advice given to the board. Several activities should therefore stay under direct internal control even if external support is used around them.

Sign-off and governance. Approval of assumptions, methodology changes and valuation results must be an internal decision made by named individuals with the authority to make it. External advisers can recommend and challenge, but they should not be the decision maker.

Day-to-day production. A quarterly valuation cycle that runs on fixed deadlines with tight data dependencies is hard to outsource without creating handoff risk. If production is outsourced, the insurer needs documented service levels, escalation routes and a tested fallback.

Model ownership. Someone inside the company should be able to explain why each material assumption was chosen and how the model reaches its output. If that knowledge exists only at the vendor, the insurer has a concentration risk that regulators will question.

Regulatory expectations on outsourcing actuarial work

An insurer that engages external actuaries is outsourcing a function that supports a regulated outcome, so the outsourcing governance framework applies. MAS Guidelines on Outsourcing and the related notice on outsourcing expect the insurer to assess materiality, perform due diligence on the service provider, define the arrangement in a written agreement and retain the ability to monitor performance and access records. MAS must be able to obtain information about the arrangement on request.

In practical terms, an engagement letter for actuarial support should cover the following points:

• Scope, deliverables and the acceptance criteria for each deliverable.
• Data confidentiality, security standards and where data and models will be stored.
• Rights of audit and access for the insurer, its external auditor and MAS.
• Subcontracting restrictions and key-person provisions.
• Exit arrangements, including return of model code, documentation and data.
• Professional standards the actuaries will observe, including independence for any peer review.

Insurers should also record the arrangement in their outsourcing register and consider it within their operational risk assessment and business continuity planning. The ORSA should not ignore a dependency that, if it failed, would delay a regulatory return.

Deciding between build, hire and outsource

A simple framework helps. For each actuarial workstream, ask four questions.

How frequent is the work? Continuous work argues for permanent staff. Work that peaks once a year or once per product launch argues for contracted support.

How specialised is the skill? A rare combination, such as RBC2 parameterisation within a specific platform, is expensive to hire and slow to replace. Renting it for a defined period is often cheaper than carrying it.

How independent must the output be? Peer review, validation and some capital challenge activities lose value if performed by the team being reviewed.

How much knowledge must remain in the company? If the answer is all of it, plan a knowledge transfer from day one, with documented methodology, annotated code and a handover session with internal staff.

Plotting your workstreams against these questions usually reveals a hybrid answer: a lean core team that owns production and sign-off, supported by external specialists for build, review and peaks. This arrangement also gives the Appointed Actuary an independent source of challenge, which supports the second-line and third-line expectations in the insurer's ERM framework.

Scoping an engagement that works

Poorly scoped actuarial engagements fail in predictable ways. The deliverable is described as "support", the insurer's data is not ready, the reviewer discovers late that documentation does not exist, and the cost grows. A few disciplines reduce that risk.

Define the end product. Name the model, the report or the study, the version of the regulation or standard it must satisfy and the audience that will use it.

Agree the data position first. Confirm what data exists, its quality and who will provide it. Data remediation is often the largest hidden cost in RBC2 and IFRS 17 work.

Set review points. Staged deliverables, such as methodology paper, build, parallel run and final report, allow the insurer to challenge early.

Plan the transfer. Make documentation and handover part of the contract rather than an afterthought, so the insurer is not dependent on the adviser to run what was built.

Align the timetable to the reporting calendar. Avoid scheduling a methodology change in the weeks before a regulatory submission or audit sign-off.

Next steps

If your actuarial team is carrying RBC2 or IFRS 17 workload that exceeds its capacity, or you need independent challenge on assumptions, models or capital projections, the first step is a short review of which workstreams are continuous, which are project-based and which require independence.
